you may receive. Be thoroughly familiar with the controls and
the proper use of the tiller and its engine. Know how to stop
the unit and disengage the controls quickly.
2. Never allow children under age 16 to operate the tiller. Never
allow adults to operate the tiller without proper instruction.
3. Keep the area of operation clear of all persons, particularly
children and pets.
4. Keep in mind that the operator or user is responsible for
accidents or hazards occurring to other people, their property,
and themselves.
Preparation
1. Thoroughly inspect the area where the tiller is to be used and
remove all foreign objects.
2. Be sure all tiller controls are released and both wheels are in
the Wheel Drive position before starting the engine.
3. Do not operate the tiller without wearing adequate outer
garments. Avoid loose garments or jewelry that could get
caught in moving parts.
4. Do not operate the tiller when barefoot or wearing sandals,
sneakers, or light footwear. Wear protective footwear that will
improve footing on slippery surfaces.
5. Do not till near underground electric cables, telephone lines,
pipes or hoses. If in doubt, contact your telephone or utility
company.
6. Warning: Handle fuel with care; it is highly flammable and its
vapors are explosive. Take the following precautions:
6a. Store fuel in containers specifically designed for this
purpose.
6b. The gas cap shall never be removed or fuel added while
the engine is running. Allow the engine to cool for several
minutes before adding fuel.
6c. Keep matches, cigarettes, cigars, pipes, open flames and
sparks away from the fuel tank and fuel container.
6d. Fill fuel tank outdoors with extreme care. Never fill fuel
tank indoors. Use a funnel or spout to prevent spillage.
6e. Replace all fuel tank and container caps securely.
6f. If fuel is spilled, do not attempt to start the engine, but
move the machine away from the area of spillage and
avoid creating any source of ignition until fuel vapors have
dissipated.
7. Never make adjustments when engine is running (unless
recommended by manufacturer).
Operation
1. Do not put hands or feet near or under rotating parts.
2. DO NOT till in reverse.
3. Exercise extreme caution when on or crossing gravel drives,
walks, or roads. Stay alert for hidden hazards or traffic. Do
not carry passengers.
4. After striking a foreign object, stop the engine, remove the
wire from the spark plug and prevent it from touching the
spark plug. Thoroughly inspect the machine for any damage
and repair the damage before restarting and operating the
machine
5. Exercise caution to avoid slipping or falling.
6. If the unit should start to vibrate abnormally, stop the engine,
disconnect the spark plug wire and prevent it from touching
the spark plug, and check immediately for the cause.
Vibration is generally a warning of trouble.
7. Stop the engine, disconnect the spark plug wire and prevent
it from touching the spark plug, whenever you leave the
operating position, before unclogging the tines,
or when making any repairs, adjustments or inspections.
8. Take all possible precautions when leaving the machine

14. Never operate the tiller under engine power if the wheels
are in the Freewheel position. In the Freewheel position,
the wheels will not hold the tiller back and the revolving tines
could propel the tiller rapidly, possibly causing loss of control.
Always engage the wheels with the wheel drive pins in the
Wheel Drive position before starting the engine or engaging
the tines⁄wheels with the forward or reverse controls.
15. Be aware that the tiller may unexpectedly bounce
upward or jump forward if the tines should strike
extremely hard packed soil, frozen ground, or buried
obstacles like large stones, roots, or stumps. If in
doubt about the tilling conditions, always use the following
operating precautions to assist you in maintaining control of
the tiller:
15a. Use shallower depth regulator settings, working
gradually deeper with each pass.
15b. Use slower engine speeds.
15c. Clear the tilling area of all large stones, roots or other
debris.
15d. Avoid using downward pressure on the handlebars.
If need be, use slight upward pressure to keep the tines
from digging too deeply.
15e. In an emergency, stop the tines and wheels by releasing
whichever lever is engaged. Do not attempt to restrain the
tiller.
16. Do not overload the tiller’s capacity by attempting to till too
deeply at too fast a rate.
17. Never operate the tiller at high transport speeds on hard or
slippery surfaces. Look behind and use care when backing
up.
18. Do not operate the tiller on a slope that is too steep for safety
(greater than 15 degrees). When on slopes, slow down and
make sure you have good footing. Never permit the tiller to
freewheel down slopes.
19. Never allow bystanders near the unit.
20. Never operate the tiller without good visibility or light.
21. Never operate the tiller if you are tired; or under the influence
of alcohol, drugs or medication.
22. Operators shall not tamper with the engine-governor settings
on the machine; the governor controls the maximum safe
operating speed to protect the engine and all moving parts
from damage caused by overspeed. Authorized service shall
be sought if a problem exists.
23. Do not touch engine parts which may be hot from operation.
Let parts cool down sufficiently.
24. Please remember: You can always stop the tines and wheels
by releasing control levers (whichever control is engaged).
25. Never pull the tiller towards you.
26. Start the engine carefully according to instructions and with
feet well away from the tines.
27. Never pick up or carry a machine while the engine is running.
Maintenance and Storage
1. Check all nuts, bolts, and screws for proper tightness to be
sure the equipment is in safe working condition.
2. Never store the tiller with fuel in the fuel tank inside a building
where ignition sources are present, such as hot water and
space heaters, furnaces, clothes dryers, stoves, electric
motors, etc. Allow the engine to cool before storing the unit in
any enclosure.
3. To reduce the chances of a fire, keep the engine free of grass,
leaves, or excessive grease.
4. Store gasoline in a cool, well-ventilated area, safely away
from any spark- or flame-producing equipment. Store
gasoline in an approved container, safely away from the reach
of children.

FLammaBLE aND EXPLOSIVE.
Fire or explosion can cause severe burns or death.
Gasoline and gasoline vapors:
– Gasoline is highly flammable and explosive.
– Gasoline can cause a fire or explosion if ignited.
– Gasoline is a liquid fuel but it’s vapors can ignite.
– Gasoline is a skin irritant and needs to be cleaned up
immediately if spilled on skin or clothes.
– Gasoline has a distinctive odor, this will help detect potential
leaks quickly.
– In any petroleum gas fire, flames should not be extinguished
unless by doing so the fuel supply valve can be turned OFF.
This is because if a fire is extinguished and a supply of fuel is
not turned OFF, then an explosion hazard could be created.
– Gasoline expands or contracts with ambient temperatures.
Never fill the gasoline tank to full capacity, as gasoline needs
room to expand if temperatures rise.
When adding or removing gasoline:
Turn the tiller off and let it cool for at least two minutes before
removing the gasoline cap. Loosen the cap slowly to relieve
pressure in the tank.
Only fill or drain gasoline outdoors in a well-ventilated area.
DO NOT pump gasoline directly into the tiller at the gas station.
Use an approved container to transfer the fuel to the tiller.
DO NOT overfill the gasoline tank.
Always keep gasoline away from sparks, open flames, pilot lights,
heat and other sources of ignition.
DO NOT light or smoke cigarettes.
When starting the tiller:
DO NOT attempt to start a damaged tiller.
Make certain that the gasoline cap, air filter, spark plug, fuel lines
and exhaust system are properly in place.
Allow spilled gasoline to evaporate fully before attempting to start
the engine.
Make certain that the tiller is resting firmly on level ground.
When operating the tiller:
DO NOT tip the tiller or allow fuel or oil to spill.
When transporting or servicing the tiller:
Make certain that the fuel valve is in the OFF position and the
gasoline tank is empty.
Disconnect the spark plug wire.
When storing the tiller:
Store away from sparks, open flames, pilot lights, heat and other
sources of ignition.
Do not store tiller or gasoline near furnaces, water heaters, or any
other appliances that produce heat or have automatic ignitions.

WARNiNG
Before operating your machine, carefully read and understand
all safety, controls and operating instructions.
Failure to follow these instructions can result in serious
personal injury.

introduction
This section describes the location and function of the controls on
your tiller. Refer to the following Section, Operation, for detailed
operating instructions.
Practice using these controls, with the engine shut off, until you
understand the operation of the controls and feel confident with
each of them.
Wheel Drive Pins
Each wheel is equipped with a locking pin that secures the wheel
to the wheel shaft. The wheels can be positioned in either a
WHEEL DRIVE or a FREEWHEEL mode.
Before starting the engine, put both wheels in the WHEEL DRIVE
position by inserting the wheel drive pins through the wheel hubs
and axle shaft. Doing so “locks” the wheels to the axle shaft,
causing the wheels to turn when either the forward or reverse
lever is engaged.
Use the FREEWHEEL mode only when the engine is not running. In
FREEWHEEL, the wheel locking pins are placed only through the
holes in the wheel shaft (not the wheel hubs), thus allowing the
wheels to turn freely when you manually move the tiller
WARNiNG
Never allow either of the wheels to be in the FREEWHEEL
position when the engine is running. Always put both wheels in
the WHEEL DRIVE position before starting the engine.
Failure to comply could cause loss of tiller control, property
damage, or personal injury.
To replace the wheels in the WhEEL DRIVE or FREEWhEEL:
1. Stop the engine, disconnect the spark plug wire from the
spark plug and allow engine to cool.
2. Raise one wheel about 1 in. (2.5 cm) off the ground and place
a sturdy support under the transmission.
WARNiNG
Do not place tiller on its side when changing wheel drive
positions. Doing so could result in gasoline leaking from the
fuel tank.
Failure to follow this instruction could result in personal injury
or property damage.
FOR WhEEL DRIVE mODE: Slide wheel outward and align the
holes. Insert locking pin through wheel hub and wheel shaft.
Secure wheel locking pin by pushing in as far as it will go then
wrapping ring around the wheel shaft as shown. Repeat with
the other wheel and then remove the support from beneath the
transmission.
WHEEL DRiVE Position
FOR FREEWhEEL mODE: Slide the wheel inward and insert the
wheel drive locking pin only through the hole in the axle shaft.
Secure wheel locking pin by pushing in as far as it will go then
wrapping ring around the wheel shaft as shown. Repeat for
the other wheel and then remove the support from beneath the
transmission.
fREEWHEEL Position
WARNiNG
Before starting engine, be sure that both wheels are in WHEEL
DRIVE position. See Wheel Drive Pins for instructions.
Engaging the Forward Lever when the wheels are not in
WHEEL DRIVE could allow the tines to rapidly propel the tiller
forward or backward. Failure to comply could cause loss of
tiller control, property damage, or personal injury
forward Lever
The Forward Lever controls the engagement of forward drive to
the wheels and counter-rotating tilling with the tines.
To operate the Forward Lever:
1. Put wheels in WHEEL DRIVE position (see “WARNING”
statement).
2. Depress and hold the lever against the handlebar to start the
wheels going forward and tines rotating in a reverse direction.
100380 - REAR TiNE TiLLER
ASSEMbLY
18
3. Release the lever to disengage (stop) the wheels and tines
(the engine will continue to run).
WARNiNG
Never pull the tiller toward you with the tines engaged.
Reverse Lever
The reverse lever controls the reverse motion of the wheels
and forward motion of the tines. To operate the Reverse
Lever:
1. Put wheels in WHEEL DRIVE position (see “WARNING”
statement).
2. Ensure all tiller tine motion has stopped before re-engaging
tines.
3. Depress and hold the lever against the handlebar to start the
wheels in reverse and tines rotating in a forward direction.
4. Release the lever to disengage (stop) the wheels and tines
(the engine will continue to run).
WARNiNG
DO NOT till in reverse.
Depth Regulator Lever Adjustment
This regulator lever controls the tilling depth of the tines. Remove
pin and clip and slide regulator lever up or down as required.
Reassemble pin and clip.
The “travel position” (highest hole) raises the tines approximately
1-1/2 in. (4 cm) off the ground, allowing the tiller to be moved
without the tines contacting the ground. This setting should also
be used when starting the engine.
Moving the regulator lever upward will increase the tilling depth.
The lowest notch allows a tilling depth of approximately 6 in. (15
cm), depending on soil conditions. For best results, always begin
tilling at a very shallow depth setting and gradually increase the
tilling depth.
WARNiNG
Do not attempt to till too deeply too quickly.
Gradually work down to deeper tilling depths.
Place the Depth Regulator Lever in the “travel” position before
starting the engine. This position prevents the tines from
touching the ground until you are ready to begin tilling.
Failure to follow this warning could result in personal injury or
property damage.

Handlebar Height Adjustment
The handlebar height is adjustable to three different settings. In
general, adjust the handlebars so they are at waist level when the
tines are 3-4 in. in the soil.
To adjust the handlebars:
1. Stop engine, disconnect spark plug wire from spark plug, and
allow engine to cool.
2. Remove hardware, reposition handlebars, and reinstall
hardware securely.

introduction
Read this section before you start the engine. Then, take the time
to familiarize yourself with the basic operation of the tiller before
using it in the garden. Find an open, level area and practice using
the tiller controls without the tines engaging the soil (put tines in
“travel” setting). Only after you’ve become completely familiar
with the tiller should you begin using it in the garden.

NOTiCE
The first 5 hours of run time are the break-in period for the
unit. During the break in period stay at or below 50% of the
running watt rating and vary the load occasionally to allow
stator windings to heat and cool. Adjusting the load will also
cause engine speed to vary slightly and help seat piston rings.
After the 5 hour break-in period, change the oil.
NOTiCE
Synthetic oil may be used after the 5 hour initial break-in
period. Using synthetic oil does not decrease the recommended
oil change interval. Full synthetic 5W-30 oil will aid in starting
in cold ambient < 41º F (5º C) temperatures.
Add fuel
DANGER
Gasoline vapors are highly flammable and extremely explosive.
DO NOT light or smoke cigarettes. Fire or explosion can cause
severe burns or death.
Only fill or drain fuel outdoors in a well-ventilated area. DO
NOT pump gasoline directly into the engine. Use an approved
container to transfer the fuel to the engine.
Never use a gasoline container, gasoline tank, or any other fuel
item that is broken, cut, torn or damaged.
DO NOT overfill the gasoline tank. Always keep fuel away from
sparks, open flames, pilot lights, heat and other sources of
ignition.
Use clean, fresh, regular unleaded gasoline with a minimum
octane rating of 87 and an ethanol content of 10% or less by
volume. ybc
DO NOT mix oil with gasoline.
1. Remove the gasoline cap.
2. Slowly add gasoline to the tank. DO NOT OVERFILL.
Gasoline can expand after filling. A minimum of ¼ in. (6.4 mm) of
space left in the tank is required for gasoline expansion although
more than ¼ in. (6.4 mm) is recommended. Gasoline can be
forced out of the tank as a result of expansion if overfilled and can
affect the stable running condition of the tiller.
CAUTiON
Use unleaded gasoline with a minimum octane rating of 87
and an ethanol content of 10% or less by volume.
DO NOT light cigarettes or smoke when filling the tank.
DO NOT mix oil and gasoline.
DO NOT overfill the tank. Fill tank to approximately ¼ in.
(6.4 mm) below the top of the tank to allow for gasoline
expansion.
DO NOT pump gasoline directly into the engine at the pump.
Use an approved fuel container to transfer the gasoline to the
engine.
DO NOT fill tank indoors.
DO NOT fill tank when the engine is running or hot.
WARNiNG
Pouring gasoline too fast through the fuel screen may result in
blow back of gasoline at the operator while filling.
100380 - REAR TiNE TiLLER
OPERATiON
21
NOTiCE
The engine works well with 10% or less ethanol blended
gasoline. When using ethanol-gasoline blends there are some
issues worth noting:
– Ethanol-gasoline blends can absorb more water than
gasoline alone.
– These ethanol blends can eventually separate, leaving
water or a watery goo in the tank, fuel valve and
carburetor. The compromised gasoline can be drawn into
the carburetor and cause damage to the engine and/or
create potential hazards.
– If a fuel stabilizer is used, confirm that it is formulated to
work with ethanol-gasoline blends.
– Any damages or hazards caused by using ethanol blended
gasoline higher than 10% by volume, improperly stored
gasoline, and/or improperly formulated stabilizers, are not
covered by manufacturer’s warranty.
It is advisable to always shut off the gasoline supply and
run the engine to starvation after each use. See Storage
instructions for extended non-use.
Transmission Gear Oil
The tiller ships from the factory with transmission gear oil
installed. Operating the tiller when the transmission is low on oil
can result in severe damage. See checking or adding Transmission
Gear Oil Service for more details.
Starting the Engine
To help prevent serious personal injury or damage to equipment
WARNiNG
Do not attempt to engage the tines or wheels until you have
read all of the operating instructions
WARNiNG
Before starting engine, put both wheels in the WHEEL DRIVE
position. Never have wheels in FREEWHEEL position when
engine is running. When the wheels are in FREEWHEEL, they
do not hold back the tiller and the tines could propel the tiller
rapidly forward or backward.
WARNiNG
Never run engine indoors or in enclosed, poorly ventilated
areas. Engine exhaust contains carbon monoxide, an odorless
and deadly gas.
WARNiNG
Keep away from rotating tines. Rotating tines will cause injury.
1. Make certain the tiller is on a flat, level surface. Tilling on a
grade greater than 15 degrees can be unsafe and cause a
low oil shut-off as oil pools in the engine opposite the low oil
sensor.
2. Put the wheels in the WHEEL DRIVE position (wheel pins must
be through holes in wheel hubs and wheel shaft).
3. Move the Depth Regulator Lever all the way down to the
“travel” position, so that the tines clear the ground.
4. Release all controls on the tiller.

NOTiCE
If the engine starts but does not run, make certain that the
tiller is on a flat, level surface. The engine is equipped with a
low oil sensor that will prevent the engine from running when
the oil level falls below a critical threshold.
Stopping the Engine and the Tiller
In an emergency, turn the engine switch to the “OFF”
position.
Under normal operation:
1. To stop the wheels and tines, release all control levers.
2. Turn the fuel valve to the “OFF” position.
fUEL Off
fUEL ON
3. Let the engine run until fuel starvation has stopped the
engine. This usually takes a few minutes.
Operation at High Altitude
The density of air at high altitude is lower than at sea level. Engine
power is reduced as the air mass and air-fuel ratio decrease.
Engine power will be reduced approximately 3½% for every 1000
ft. of elevation above sea level. This is a natural trend and cannot
be changed by adjusting the engine. At high altitudes increased
exhaust emissions can also result due to the increased enrichment
of the air fuel ratio. Other high altitude issues can include hard
starting, increased fuel consumption and spark plug fouling.
To alleviate high altitude issues other than the natural power
loss, CPE can provide a high altitude carburetor main jet. The
alternative main jet and installation instructions can be obtained
by contacting our Technical Support Team. Installation instructions
are also available in the Technical Bulletin area of the CPE website.
The part number and recommended minimum altitude for the
application of the high altitude carburetor main jet is listed in the
table below.
100380 - REAR TiNE TiLLER
TiLLiNG TiPS AND TECHNiQUES

In order to select the correct high altitude main jet it is necessary
to identify the carburetor model. For this purpose, a code is
stamped on the side of the carburetor. Select the correct high
altitude jet part number corresponding to the carburetor code
found on your particular carburetor.

WARNiNG
Operation using the alternative main jet at elevations lower
than the recommended minimum altitude can damage the
engine. For operation at lower elevations, the originally
supplied standard main jet must be used. Operating the
engine with the wrong engine configuration at a given altitude
may increase its emissions and decrease fuel efficiency and
performance.
TiLLiNG TiPS AND TECHNiQUES
Tilling Depths
WARNiNG
Before tilling, contact your telephone or utilities company and
inquire if underground equipment or lines are used on your
property. Do not till near buried electric cables, telephone
lines, pipes or hoses.
Avoid pushing down on the handlebars in an attempt to force the
tiller to dig deeper. Doing so takes the weight off the powered
wheels, causing them to lose traction. Without the wheels
helping to hold the tiller back, the tines will attempt to propel the
tiller – often causing the tiller to skip rapidly across the ground.
(Sometimes, slight downward pressure on the handlebars will
help get through a particularly tough section of sod or unbroken
ground, but in most cases this wont be necessary.)
Avoid trying to dig too deeply too quickly, especially when busting
sod or when tilling soil that hasn’t been tilled for some time. Use
shallow depth regulator settings (only an inch or two deep) for
the first passes through the soil. With each succeeding pass, dig
another inch or two deeper. (Watering the area a few days prior to
tilling will make the tilling easier, as will letting the newly worked
soil set for a day or two before making a final, deep tilling pass.
When cultivating (breaking up surface soil around plants to
destroy weeds), adjust the tines to dig only 1 in. to 2 in. (2.5 to
5 cm) deep. Using shallow tilling depths helps prevent injury to
plants whose roots often grow close to the surface. If needed, lift
up on the handlebars slightly to prevent the tines from digging too
deeply. (Cultivating on a regular basis not only eliminates weeds,
it also loosens and aerates the soil for better moisture absorption
and faster plant growth.)
Choosing Correct Wheel and Tine Speeds
With experience, you will find the “just right” tilling depth and
tilling speed combination that is best for your garden.
Set the engine throttle lever at a speed to give the engine
adequate power and yet allow it to operate at the slowest possible
speed ... at least until you have achieved the maximum tilling
depth you desire. Faster engine speeds may be desirable when
making final passes through the seedbed or when cultivating.
Selection of the correct engine speed, in relation to the tilling
depth, will ensure a sufficient power level to do the job without
causing the engine to labor.
Let the Tiller Do the Work
While tilling, relax and let the wheels pull the tiller along while the
tines do the digging. Walk on the side that is not yet finished (to
avoid making footprints in the freshly tilled soil) and lightly, but
securely grip the handlebar with just one hand.
Avoid Tilling Soggy, Wet Soil
Tilling wet soil often results in large, hard clumps of soil that can
interfere with planting. If time permits, wait a day or two after
heavy rains to allow the soil to dry before tilling. Test soil by
squeezing it into a ball. If it compresses too easily, it is too wet to
till.
Preparing Seedbeds
When preparing a seedbed, go over the same path twice in the
first row, then overlap one-half the tiller width on the rest of the
passes. When finished in one direction, make a second pass at
a right angle. Overlap each pass for best results (in very hard
ground, it may take three or four passes to thoroughly pulverize
the soil.)
If the garden size will not permit lengthwise and then crosswise
tilling, then overlap the first passes by one-half a tiller width,
followed by successive passes at one quarter width.
100380 - REAR TiNE TiLLER
TiLLiNG TiPS AND TECHNiQUES
24
Cultivating
With planning, you can allow enough room between rows to
cultivate. Leave room for the hood width, plus enough extra room
for future plant growth.
Tilling on Slopes
Read the following recommendations before tilling on slopes:
If you must garden on a moderate slope, please follow two very
important guidelines:
1. Till only on moderate slopes, never on steep ground where
footing is difficult. Tilling on a grade greater than 15 degrees
can be unsafe and cause a low oil shut-off as oil pools in the
engine opposite the low oil sensor.
2. We recommend tilling up and down slopes rather than
terracing. Tilling vertically on a slope allows maximum
planting area and also leaves room for cultivating.
IMPORTANT: When tilling on slopes, be sure the correct oil
level is maintained in the engine (check every one-half hour of
operation). The incline of the slope will cause the oil to slant away
from its normal level and this can starve engine parts of required
lubrication. Keep the engine oil level at the full point at all times!
WARNiNG
Do not operate tiller on a slope too steep for safe operation. Till
slowly and be sure you have good footing. Never permit tiller
to freewheel down slopes. Failure to follow this warning could
result in personal injury.
Tilling on slopes greater than 15 degrees can be unsafe and
cause a low oil shut-off due to oil pooling in the opposite side
of the engine to the low oil sensor.
Tilling Up and Down Slopes (Vertical Tilling)
To keep soil erosion to a minimum, be sure to add enough organic
matter to the soil so that it has good moisture-holding texture and
try to avoid leaving footprints or wheel marks.
When tilling vertically, try to make the first pass uphill as the tiller
digs more deeply going uphill than it does downhill. In soft soil or
weeds, you may have to lift the handlebars slightly while going
uphill. When going downhill, overlap the first pass by about one-
half the width of the tiller.
Tilling across Slopes Without Using Terraces (horizontal
Tilling)
If vertical or terracing gardening aren’t practical for you, then you
can till laterally across a slope. We don’t recommend this method
as it can create unsure footing and invites soil erosion.
As in terrace gardening, start at the top of the slope and overlap
the first pass by half the width of the tiller. For added stability of
the tiller, always keep the uphill wheel in the soft, newly tilled soil.
Terrace Gardening
– When a slope is too steep or too short for vertical tilling, it may
be necessary to till across the slope and create terraced rows.
Terraces are rows that are cut into the side of a slope, creating
a narrow, but flat area on which to plant.
– On a long slope, you can make several terraces, one below the
other.
– Terraces should be only 2-to-3 ft. (60-90 cm) wide. Digging
too far into the side of the slope will expose poor subsoil that is
unproductive for plants.
– To create a terrace, start at the top of the slope and work
down. Go back and forth across the first row.
– Each succeeding lower terrace is started by walking below
the terrace you’re preparing. For added stability of the tiller,
always keep the uphill wheel in the soft, newly tilled soil.
Do not till the last 12 in. (30 cm) or more of the downhill
outside edge of each terrace. This untilled strip helps prevents
the terraces from breaking apart and washing downhill. It also
provides a walking path between rows.
Clearing the Tines
The tines have a self-clearing action which eliminates most
tangling of debris in the tines. However, occasionally dry grass,
stringy stalks or tough vines may become tangled. Follow these
procedures to help avoid tangling and to clean the tines, if
necessary.
– To reduce tangling, set the depth regulator deep enough to get
maximum “chopping” action as the tines chop the material
against the ground. Also, try to till under crop residues or cover
crops while they are green, moist and tender.
– While power composting, try swaying the handlebars from side
to side about 6 in. to 12 in. (15 to 30 cm). This “fishtailing”
action often clears the tines of debris.
– If tangling occurs, lift the tines out of the soil and run the tiller
in reverse (if unit is equipped with powered reverse) for a
few feet. This reversing action should unwind a good deal of
debris.
– It may be necessary to remove the debris by hand (a pocket
knife will help you to cut away the material). Be sure to stop
the engine and disconnect the spark plug wire before clearing
the tines by hand.
WARNiNG
Before clearing the tines by hand, stop the engine, allow all
moving parts to stop and disconnect the spark plug wire.
Remove the ignition key on electric start models.
Failure to follow this warning could result in personal injury.

Loading and Unloading the Tiller
WARNiNG
Loading and unloading the tiller into a vehicle is potentially
hazardous and we don’t recommend doing so unless
absolutely necessary, as this could result in personal injury
or property damage. However, if you must load or unload the
tiller, follow the guidelines given next.
– Before loading or unloading, stop the engine, wait for all parts
to stop moving, disconnect the spark plug wire and let the
engine and muffler cool.
– The tiller is too heavy and bulky to lift safely by one person.
Two or more people should share the load.
– Use sturdy ramps and manually (engine shut off) roll the tiller
into and out of the vehicle. Two or more people are needed to
do this.
– The ramps must be strong enough to support the combined
weight of the tiller and any handlers. The ramps should provide
good traction to prevent slipping; they should have side rails
to guide the tiller along the ramps; and they should have a
locking device to secure them to the vehicle.
– The handlers should wear sturdy footwear that will help to
prevent slipping.
– Position the loading vehicle so that the ramp angle is as flat
as possible (the less incline to the ramp, the better). Turn the
vehicle’s engine off and apply its parking brake.
– When going up ramps, stand in the normal operating position
and push the tiller ahead of you. Have a person at each side to
turn the wheels.
– When going down ramps, walk backward with the tiller
following you. Keep alert for any obstacles behind you. Position
a person at each wheel to control the speed of the tiller. Never
go down ramps tiller-first, as the tiller could tip forward.
– Place wooden blocks on the downhill side of the wheels if you
need to stop the tiller from rolling down the ramp. Also, use
the blocks to temporarily keep the tiller in place on the ramps
(if necessary), and to chock the wheels in place after the tiller
is in the vehicle.
– After loading the tiller, prevent it from rolling by engaging the
wheels in the WHEEL DRIVE position. Chock the wheels with
blocks and securely tie the tiller down.

Tiller Lubrication
After every 10 operating hours, oil or grease the lubrication points
as described below.
Use clean lubricating oil (#30 weight engine oil is suitable) and
clean general purpose grease (grease containing a metal lubricant
is preferred, if available).
– Remove the wheels, clean the wheel shaft and apply a thin
coating of grease to the wheel shaft.
– Grease the back, front and sides of the depth regulator lever.
– Remove the tines and clean the tine shaft. Use a file or
sandpaper to gently remove any rust, burrs or rough spots
(especially around holes in shaft). Apply grease to ends of
shaft before installing tines.
– Oil the threads on the handlebar height adjustment screws and
the handlebar attaching screws.
Check for Oil Leaks
Before each use, check the tiller for signs of an oil leak — usually
a dirty, oily accumulation either on the unit or on the floor.
A little seepage around a cover or an oil seal is usually not a cause
for alarm. However, if the oil drips overnight, then immediate
attention is needed. Ignoring an oil leak can result in severe
transmission damage!
If a cover is leaking, check for loose screws. If the screws are
tight, a new gasket or oil seal may be required.
If the leak is from around a shaft and oil seal, the oil seal probably
needs to be replaced. See your authorized dealer or contact the
factory for service or advice.
ImPORTaNT: Never operate the tiller if the transmission is low
on oil. Check the oil level after every 30 hours of operation and
whenever there is any oil leakage.
Check Hardware
Check for loose or missing hardware after every 10 operating
hours and tighten or replace (as needed) before reusing tiller.
Be sure to check the screws underneath the tiller hood that secure
the transmission cover and the Depth Regulator Lever to the
transmission.
Check Tire Pressure
Check the air pressure in both tires. The air pressure should not
be more than 30 PSI (pounds per square inch).
Keep both tires equally inflated to help prevent machine from
pulling to one side.
Transmission Gear Oil Service
Check the transmission gear oil level after every 30 hours of
operation or whenever you notice any oil leak. Operating the tiller
when the transmission is low on oil can result in severe damage.
a. To Check the Transmission Gear Oil Level:
1. Check the gear oil level when the transmission is cool. Gear
oil will expand in warm operating temperatures and this
expansion will provide an incorrect oil level reading.
2. With the tiller on level ground, pull the Depth Regulator Lever
all the way up.
3. Remove the dipstick/oil fill plug from the transmission
housing and look inside the oil fill hole to locate the main
drive shaft situated below the hole.

DIPSTICK
4. The gear oil level is correct if it falls between the two nodes
on the oil dipstick.
5. If the gear oil level is low, add GL-4 gear oil (SAE 85W-140 or
SAE 140).
6. If the gear oil level is okay, securely replace the oil fill plug.
ImPORTaNT: Do not operate the tiller if the gear oil level is
low. Doing so will result in severe damage to the transmission
components.
B. To Drain the Transmission Gear Oil:
The transmission gear oil does not need to be changed unless it
has been contaminated with dirt, sand or metal particles.
1. Drain gasoline from the fuel tank or run the engine until the
fuel tank is empty. See “DANGER” statement below.
2. Drain the oil from the engine.
3. Remove the drain bolt from the bottom of the transmission
and allow the gear oil to drain completely.
5. Reinstall the drain bolt.
6. Refill the transmission using GL-4 gear oil (SAE 85W-140 or
SAE 140).
7. Refill the engine with engine oil and replenish the fuel tank
with gasoline.
Tines
The tines will wear with use and should be inspected at the
beginning of each tilling season and after every 30 operating
hours. The tines can be replaced either individually or as a
complete set. Refer to the parts list for tine identification and part
numbers.
a. Tine Inspection:
With use, the tines will become shorter, narrower and pointed.
Badly worn tines will result in a loss of tilling depth, and reduced
effectiveness when chopping up and turning under organic matter.
B. Removing/Installing a Single Tine:
1. With the engine shut off and the spark plug wire
disconnected, remove the M10×25 bolt, lock washer, flat
washer and M10 nut that attach a single tine to a tine holder.
If needed, use penetrating oil on the nuts.
2. When installing a single tine, be sure to position it so that its
cutting edge (sharp) will enter the soil first as the tiller moves
forward. Hand tighten completely.
C. Removing/Installing a Tine assembly:
1. A tine assembly consists of eight tines mounted on a tine
holder.
2. If removing both tine assemblies, mark them “left” and
“right” before removal. Remove (2) pins and (2) cotter pins
that secure the tine assembly to the tine shaft. If necessary,
use a rubber mallet to tap the tine assembly outward off the
shaft.
3. Before reinstalling the tine assembly, inspect the tine shaft
for rust, rough spots or burrs. Lightly file or sand, as needed.
Apply a thin coat of grease to the shaft.
4. Install each tine assembly so that the cutting (sharp) edge of
the tines will enter the soil first when the tiller moves forward.
5. Bend cotter pins once inserted to prevent the pins from
coming out.

Checking and Adjusting forward Drive belt
Tension
It is important to maintain correct tension on the forward drive
belt. A loose belt will cause the tines and wheels to slow down
— or stop completely — even though the engine is running at full
speed. A too-tight belt can result in unintentional tine movement
when the lever is in the Neutral (released) position.
– Check belt tension after the first two hours of break-in
operation and after every 10 operating hours.
– At the end of each tilling season, check the belt for cracks,
cuts or frayed edges, and replace it as soon as possible.
To Check Belt Tension:
1. Stop engine, wait for all parts to stop moving and disconnect
spark plug wire.
2. With the forward and reverse lever in an open (released)
position, measure and note the overall length of the cable
spring by measuring from the outermost coil to the outermost
coil.
fORWARD LEVER
REVERSE LEVER
3. Squeeze the forward lever against the handlebar and re-
measure the length of the coils. The belt tension is correct if
this second measurement is between 1/6 in. to 3/16 in. (2-5
mm) shorter than the first measurement.
4. If the spring is too short (less than 1/16 in. [2 mm]), the
tension is too tight. If the spring is too long (more than 3/16
in. [5 mm]), the tension is too loose.
5. To adjust the length of the spring.
1. Release the forward lever.
2. Un-thread the hex nut halfway up the adjustment screw.
3. Unhook the top of the spring from the lever.
4. Use pliers to prevent the adjuster from turning and turn
the slotted screw located inside the spring clockwise
(viewed from operator’s position) to increase tension on
the spring. Turn the screw counter-clockwise to decrease
tension. Once adjusted, reattach the spring to the lever.
5. Repeat Steps 2 and 3 to re-measure the length of the
spring. When the second measurement is between
1/16 in. to 3/16 in. (2 to 5 mm) shorter than the first
measurement, re-tighten the hex nut against the top of
the adjuster.

Air Cleaner Service
The air cleaner filters dirt and dust out of the air before it enters
the carburetor. Operating the engine with a dirty, clogged air
filter can cause poor performance and damage to the engine.
Never operate the engine without the air cleaner installed. Inspect
and service the air cleaner more often if operating in very dusty
or dirty conditions. Refer to the engine Owner’s Manual for air
cleaner service intervals and instructions.
Engine Oil Service
Check the engine oil level before each use and after every five
hours of continuous operation. Running the engine when it is low
on oil will quickly ruin the engine.
It is recommended that you change the engine oil after every 10
hours of operation and even sooner when operating in extremely
dirty or dusty conditions.
a. To Check the Engine Oil Level:
1. Park the tiller on a level area and shut off the engine.
2. Level the engine (use the Depth Regulator Lever to adjust the
engine angle).
3. Clean around the oil dipstick to prevent dirt from falling into
the crankcase.
4. On engines with a dipstick, remove it and wipe it clean.
Reinsert the dipstick, tighten it securely, and remove it. Add
oil as needed to bring the level up to the FULL mark. Wipe
dipstick clean each time oil level is checked. Do not overfill.
Tighten dipstick securely.

CHAMPION POWER EQUIPMENT, INC. (CPE),
THE UNITED STATES ENVIRONMENTAL PROTECTION AGENCY (U.S. EPA)
AND THE CALIFORNIA AIR RESOURCES BOARD (CARB) EMISSION CONTROL SYSTEM WARRANTY
Your Champion Power Equipment (CPE) engine complies with both the U.S. EPA and state of California Air Resources Board
(CARB) Exhaust and Evaporative emissions regulations.
YOUR WARRANTY RIGHTS AND OBLIGATIONS:
The US EPA, California Air Resources Board, and CPE are pleased to explain the Federal and California Exhaust and Evaporative Emission
Control Systems Warranty on your 2023 small off-road engine (SORE) and engine powered equipment. In California, new equipment that
use small off-road engines (SORE) must be designed, built and equipped to meet the State’s stringent anti-smog standards.
CPE must warrant the exhaust and evaporative emission control system on your small off-road engine (SORE) for the period listed below,
provided there has been no abuse, neglect, unapproved modification, or improper maintenance of your equipment leading to the failure of
the exhaust and evaporative emission control systems.
Your evaporative emission control system may include parts such as: carburetors, fuel tanks, fuel lines, (for liquid fuel and fuel vapors),
fuel caps, valves, canisters, filters, clamps, connectors, and other associated components. Also included for your exhaust emission control
system may be the fuel-injection system, the ignition system, catalytic converter and other exhaust emission related assemblies. Where a
warrantable condition exits, CPE will repair your small off-road engine (SORE) at no cost to you including diagnosis, parts and labor.
MANUFACTURER’S WARRANTY COVERAGE:
This exhaust and evaporative emission control system is warranted for two years. If any exhaust and evaporative, emission related part on
your engine or equipment is defective in, the part will be repaired or replaced by CPE.
OWNER WARRANTY RESPONSIBILITIES:
As the small off-road engine (SORE) owner, you are responsible for the performance of the required maintenance listed in your Owner’s
Manual. CPE recommends that you retain all your receipts covering maintenance on your small off-road engine (SORE), but CPE cannot
deny warranty coverage solely for the lack of receipts.
As the small off-road engine (SORE) owner, you should be aware that CPE may deny you warranty coverage if your small off-road engine
(SORE) or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.
You are responsible for presenting your small off-road engine to an Authorized CPE distribution center, service center or alternate service
outlet as described in (3)(f) below or CPE dealer or CPE, Santa Fe Springs, Ca. as soon as the problem exists. The warranty repairs shall be
completed in a reasonable amount of time, not to exceed 30 days.

EXHAUST AND EVAPORATIVE EMISSION CONTROL SYSTEM WARRANTY
The following are specific provisions relative to your Exhaust and Evaporative Emission Control System (ECS) Warranty
Coverage.
1. APPLICABILITY: This warranty shall apply to 1995 and later model year California small off-road engines (SORE) (for other states,
1997 and later model year engines). The ECS Warranty Period shall begin on the date the new engine or equipment is delivered to its
original, end-use purchaser, and shall continue for 24 consecutive months thereafter.
2. GENERAL EMISSIONS WARRANTY COVERAGE
CPE warrants to the original, end-use purchaser of the new engine or equipment and to each subsequent purchaser that each of its
small off-road engines (SORE) is:
2a. Designed, built and equipped to conform to U.S. EPA emissions standards for spark-ignited engines at or below 19 kilowatts and
all applicable regulations adopted by the California Air Resources Board and
2b. Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material respects
to the part as described in the engine manufacturer’s application for certification for a period of two years.
3. THE WARRANTY ON EXHAUST AND EVAPORATIVE EMISSION-RELATED PARTS WILL BE INTERPRETED AS FOLLOWS:
3a. Any warranted part that is not scheduled for replacement as required maintenance in the Owner’s Manual shall be warranted for
the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall be repaired or replaced by CPE according
to Subsection “d” below. Any such part repaired or replaced under the ECS Warranty shall be warranted for any remainder of the
ECS Warranty Period.
3b. Any warranted, exhaust and evaporative emissions-related part which is scheduled only for regular inspection as specified in the
Owner’s Manual shall be warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair
or replace as necessary”, shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty
shall be warranted for the remainder of the ECS Warranty Period.
3c. Any warranted, exhaust and evaporative emissions-related part which is scheduled for replacement as required maintenance in
the Owner’s Manual shall be warranted for the period of time prior to the first scheduled replacement point for that part. If the part
fails prior to the first scheduled replacement, the part shall be repaired or replaced by CPE according to Subsection “d” below.
Any such exhaust and evaporative emissions-related part repaired or replaced under the ECS Warranty, shall be warranted for the
remainder of the ECS Warranty Period prior to the first scheduled replacement point for such emissions-related part.
3d. Repair or replacement of any warranted, exhaust and evaporative emissions-related part under this ECS Warranty shall be
performed at no charge to the owner at a CPE Authorized Service Outlet.
3e. The owner shall not be charged for diagnostic labor which leads to the determination that a part covered by the ECS Warranty is in
fact defective, provided that such diagnostic work is performed at a CPE Authorized Service Outlet.
3f. CPE shall pay for covered exhaust and evaporative emissions warranty repairs at non-authorized service outlets under the
following circumstances:
i. The service is required in a population center with a population over 100,000 according to U.S. Census 2000 without a CPE
Authorized Service Outlet AND
ii. The service is required more than 100 miles from a CPE Authorized Service Outlet. The 100 mile limitation does not apply in the
following states: Alaska, Arizona, Colorado, Hawaii, Idaho, Montana, Nebraska, Nevada, New Mexico, Oregon, Texas, Utah and
Wyoming.
3g. CPE shall be liable for damages to other original engine components or approved modifications proximately caused by a failure
under warranty of an emission-related part covered by the ECS Warranty.
3h. Throughout the ECS Warranty Period, CPE shall maintain a supply of warranted exhaust and evaporative emission-related parts
sufficient to meet the expected demand for such exhaust and evaporative emission-related parts.
3i. Any CPE Authorized and approved exhaust and evaporative emission-related replacement part may be used in the performance
of any ECS Warranty maintenance or repair and will be provided without charge to the owner. Such use shall not reduce CPE’s
warranty obligation.
3j. Unapproved add-on or modified parts may not be used to modify or repair a CPE engine. Such use voids this ECS Warranty and
shall be sufficient grounds for disallowing an ECS Warranty claim. CPE shall not be liable hereunder for failures of any warranted
parts of a CPE engine caused by the use of such an unapproved add-on or modified part.
