A missing or damaged discharge cover can cause blade 12.
contact or thrown object injuries.
Many injuries occur as a result of the mower being pulled 13.
over the foot during a fall caused by slipping or tripping.
Do not hold on to the mower if you are falling; release the
handle immediately.
Never pull the mower back toward you while you are 14.
walking. If you must back the mower away from a wall or
obstruction first look down and behind to avoid tripping
and then follow these steps:
Step back from mower to fully extend your arms.a.
Be sure you are well balanced with sure footing.b.
Pull the mower back slowly, no more than half way c.
toward you.
Repeat these steps as needed.d.
Do not operate the mower while under the influence of 15.
alcohol or drugs.
Do not engage the self-propelled mechanism on machines 16.
so equipped while starting engine.
The blade control handle is a safety device. Never attempt 17.
to bypass its operation. Doing so makes the safety device
inoperative and may result in personal injury through
contact with the rotating blade. The blade control handle
must operate easily in both directions and automatically
return to the disengaged position when released.
Never operate the mower in wet grass. Always be sure of 18.
your footing. A slip and fall can cause serious personal
injury. If you feel you are losing your footing, release the
blade control handle immediately and the blade will stop
rotating within three seconds.
Mow only in daylight or good artificial light. Walk, never 19.
run.
Stop the blade when crossing gravel drives, walks or roads.20.
If the equipment should start to vibrate abnormally, stop 21.
the engine and check immediately for the cause. Vibration
is generally a warning of trouble.
Shut the engine off and wait until the blade comes to 22.
a complete stop before removing the grass catcher or
unclogging the chute. The cutting blade continues to
rotate for a few seconds after the blade control is released.
Never place any part of the body in the blade area until you
are sure the blade has stopped rotating.
Never operate mower without proper trail shield, discharge 23.
cover, grass catcher, blade control handle or other safety
protective devices in place and working. Never operate
mower with damaged safety devices. Failure to do so can
result in personal injury.
Muffler and engine become hot and can cause a burn. Do 24.
not touch.
Never attempt to make a wheel or cutting height 25.
adjustment while the engine is running.
Only use parts and accessories made for this machine by 26.
the manufacturer. Failure to do so can result in personal
injury.
When starting engine, pull cord slowly until resistance 27.
is felt, then pull rapidly. Rapid retraction of starter cord
(kickback) will pull hand and arm toward engine faster than
you can let go. Broken bones, fractures, bruises or sprains
could result.
If situations occur which are not covered in this manual, 28.
use care and good judgement. Contact Customer Support
for assistance or the name of the nearest service dealer.
Slope Operation
Slopes are a major factor related to slip and fall accidents, which
can result in severe injury. Operation on slopes requires extra
caution. If you feel uneasy on a slope, do not mow it. For your
safety, use the slope gauge included as part of this manual to
measure slopes before operating this machine on a sloped or
hilly area. If the slope is greater than 15 degrees, do not mow it.
Do:
Mow across the face of slopes; never up and down. Exercise 1.
extreme caution when changing direction on slopes.
Watch for holes, ruts, rocks, hidden objects, or bumps 2.
which can cause you to slip or trip. Tall grass can hide
obstacles.
Always be sure of your footing. A slip and fall can cause 3.
serious personal injury. If you feel you are losing your
balance, release the blade control handle immediately and
the blade will stop rotating within three (3) seconds.
Do Not:
Do not mow near drop-offs, ditches or embankments, you 1.
could lose your footing or balance.
Do not mow slopes greater than 15 degrees as shown on 2.
the slope gauge.
Do not mow on wet grass. Unstable footing could cause 3.
slipping.
Children
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the mower
and the mowing activity. They do not understand the dangers.
Never assume that children will remain where you last saw them.
Keep children out of the mowing area and under watchful 1.
care of a responsible adult other than the operator.
Be alert and turn mower off if a child enters the area.2.
Before and while moving backwards, look behind and 3.
down for small children.
Use extreme care when approaching blind corners, 4.
doorways, shrubs, trees, or other objects that may obscure
your vision of a child who may run into the mower.
Keep children away from hot or running engines. They can 5.
suffer burns from a hot muffler.
Never allow children under 14 years of age to operate this 6.
machine. Children 14 and over should read and understand
the instructions and safe operation practices in this manual
and on the machine and be trained and supervised by an
adult.

Safe Handling Of Gasoline:
To avoid personal injury or property damage use extreme 1.
care in handling gasoline. Gasoline is extremely flammable
and the vapors are explosive. Serious personal injury can
occur when gasoline is spilled on yourself or your clothes,
which can ignite. Wash your skin and change clothes
immediately.
Use only an approved gasoline container.2.
Never fill containers inside a vehicle or on a truck or trailer 3.
bed with a plastic liner. Always place containers on the
ground away from your vehicle before filling.
Remove gas-powered equipment from the truck or 4.
trailer and refuel it on the ground. If this is not possible,
then refuel such equipment on a trailer with a portable
container, rather than from a gasoline dispenser nozzle.
Keep the nozzle in contact with the rim of the fuel tank or 5.
container opening at all times until fueling is complete. Do
not use a nozzle lock-open device.
Extinguish all cigarettes, cigars, pipes and other sources 6.
of ignition.
Never fuel machine indoors because flammable vapors will 7.
accumulate in the area.
Never remove gas cap or add fuel while engine is hot or 8.
running. Allow engine to cool at least two minutes before
refueling.
Never over fill fuel tank. Fill tank to no more than 1 inch 9.
below bottom of filler neck to provide for fuel expansion.
Replace gasoline cap and tighten securely.10.
If gasoline is spilled, wipe it off the engine and equipment. 11.
Move machine to another area. Wait 5 minutes before
starting engine.
Never store the machine or fuel container near an open 12.
flame, spark or pilot light as on a water heater, space
heater, furnace, clothes dryer or other gas appliances.
To reduce fire hazard, keep machine free of grass, leaves, 13.
or other debris build-up. Clean up oil or fuel spillage and
remove any fuel soaked debris.
Allow machine to cool at least 5 minutes before storing.14.
General Service:
Never run an engine indoors or in a poorly ventilated area. 1.
Engine exhaust contains carbon monoxide, an odorless
and deadly gas.
Before cleaning, repairing, or inspecting, make certain the 2.
blade and all moving parts have stopped. Disconnect the
spark plug wire and ground against the engine to prevent
unintended starting.
Check the blade and engine mounting bolts at frequent 3.
intervals for proper tightness. Also, visually inspect blade
for damage (e.g., bent, cracked, worn) Replace blade with
the original equipment manufacture’s (O.E.M.) blade only,
listed in this manual. “Use of parts which do not meet the
original equipment specifications may lead to improper
performance and compromise safety!”
Mower blades are sharp and can cut. Wrap the blade or 4.
wear gloves, and use extra caution when servicing them.
Keep all nuts, bolts, and screws tight to be sure the 5.
equipment is in safe working condition.
Never tamper with safety devices. Check their proper 6.
operation regularly.
After striking a foreign object, stop the engine, disconnect 7.
the spark plug wire and ground against the engine.
Thoroughly inspect the mower for any damage. Repair the
damage before starting and operating the mower.
Never attempt to make a wheel or cutting height 8.
adjustment while the engine is running.
Grass catcher components, discharge cover, and trail shield 9.
are subject to wear and damage which could expose
moving parts or allow objects to be thrown. For safety
protection, frequently check components and replace

which do not meet the original equipment specifications
may lead to improper performance and compromise
safety!”
Do not change the engine’s governor setting or over-speed 10.
the engine. The governor controls the maximum safe
operating speed of the engine.
Check fuel line, tank, cap, and fittings frequently for cracks 11.
or leaks. Replace if necessary.
Do not crank engine with spark plug removed.12.
Maintain or replace safety and instruction labels, as 13.
necessary.
Observe proper disposal laws and regulations. Improper 14.
disposal of fluids and materials can harm the environment.
According to the Consumer Products Safety Commission 15.
(CPSC) and the U.S. Environmental Protection Agency (EPA),
this product has an Average Useful Life of seven (7) years,
or 140 hours of operation. At the end of the Average Useful

Starting Engine
WARNING: Be sure no one other than the operator
is standing near the lawn mower while starting
engine or operating mower. Never run engine
indoors or in enclosed, poorly ventilated areas.
Engine exhaust contains carbon monoxide, an
odorless and deadly gas. Keep hands, feet, hair and
loose clothing away from any moving parts on
engine and lawn mower.
Refer to engine manual for help with the engine.
Push primer (if equipped) three times. Wait about two 1.
seconds between each push. See Figure 5-1. In temperature
around 55° F or below, prime five times. Do not prime to
restart a warm engine.
Standing behind the mower, squeeze the blade control 2.
against upper handle.
Recoil Start:3. Holding these two handles together firmly,
grasp recoil starter handle and pull rope out with a rapid,
continuous, full arm stroke. See Figure 5-1. Keeping a firm
grip on the starter handle, let the rope rewind slowly.
Repeat until engine cranks. Let the rope rewind each time
slowly.
Electric Start: Turn ignition key to the right to start the
engine. Release the key after the engine starts.
Stopping Engine
Release blade control to stop the engine and blade.1.
WARNING: Wait for the blade to stop completely
before performing any work on the mower or to
remove the side discharge chute.
Using Your Lawn Mower
Be sure lawn is clear of stones, sticks, wire, or other objects
which could damage lawn mower or engine. Such objects could
be accidently thrown by the mower in any direction and cause
serious personal injury to the operator and others.
WARNING: If you strike a foreign object, stop the
engine. Remove wire from the spark plug,
thoroughly inspect mower for any damage, and
repair damage before restarting and operating.
Extensive vibration of mower during operation is an
indication of damage. The unit should be promptly
inspected and repaired.
Using as Mulcher
For mulching grass, remove the grass catcher and the side
discharge chute from the mower. For effective mulching, do not
cut wet grass. If the grass has been allowed to grow in excess of
four inches, mulching is not recommended. Use the grass catcher
to bag clippings instead.
WARNING: The operation of any lawn mower can
result in foreign objects being thrown into the eyes,
which can damage your eyes severely. Always wear
safety glasses while operating the mower, or while
performing any adjustments or repairs on it.
Using Grass Catcher
You can use the grass catcher bag to collect clippings while
you are operating the mower. The grass bag is equipped with
a bag-fill indicator to add convenience to your work. While the
mower is running, air will flow through the bag and into the
Grass Gauge. If the grass catcher is empty, air flows through
easily pushing the gauge up. If the grass catcher is full, air does
not flow through it allowing the gauge to fall. So the position of
the gauge acts as a bag-fill indicator signifying when to empty
the grass bag.
Attach grass catcher following instructions in “Setup and 1.
Adjustment”. Grass clippings will automatically collect in
the bag as you run the mower.
Operate the mower till the grass bag is full.2.
Stop engine completely by releasing the blade control. 3.
Make sure that the unit has come to a complete stop.
While holding the grass bag by both the rear handle and 4.
the lower handle, lift the grass bag straight up off the
adapter. The chute door will move the rope out of the way
of the bag.
Continue to hold the lower handle and raise the rear of the 5.

Maintenance
General Recommendations
Always observe safety rules when performing any •
maintenance.
The warranty on this lawn mower does not cover items that •
have been subjected to operator abuse or negligence. To
receive full value from warranty, operator must maintain
the lawn mower as instructed here.
Changing of engine-governed speed will void engine •
warranty.
All adjustments should be checked at least once each •
season.
Periodically check all fasteners and make sure these are •
tight.
WARNING: Always stop engine, disconnect spark
plug, and ground against engine before performing
any type of maintenance on your machine.
Lubrication
Lubricate pivot points on the blade control at least once a 1.
season with light oil. The blade control must operate freely
in both directions. See Fig. 6-1.
Lubricate the wheels and casters at least once a season 2.
with light oil (or motor oil). If wheels are removed for any
reason, lubricate the axle bolt and inner surface of the
wheel with light oil. See Fig. 6-1.
Lubricate the torsion spring and pivot point on each end of 3.
the grass catcher adapter door at least once a season with
light oil to prevent rust. See Fig. 6-1.
The transmission is pre-lubricated and sealed at the factory 4.
and does not require lubrication.
Follow the accompanying engine manual for lubrication 5.
schedule and instruction for engine lubrication.
Deck Care
Clean underside of the mower deck after each use to prevent
build-up of grass clippings or other debris. Follow steps below
for this job.
Disconnect spark plug wire. Drain gasoline from lawn 1.
mower or place a piece of plastic under the gas cap.
Tip mower so that it rests on the housing. Keep the side 2.
with the air cleaner facing up. Hold mower firmly.
WARNING: Never tip the mower more than 90º in
any direction and do not leave the mower tipped for
any length of time. Oil can drain into the upper part
of the engine causing a starting problem.
3. Scrape and clean the underside of the deck with a suitable
tool. Do not spray with water.
IMPORTANT: Do not use a pressure washer or garden hose
to clean your unit. These may cause damage to bearings,
or the engine. The use of water will result in shortened life
and reduce serviceability.
4. Put the mower back on its wheels on the ground. If you had
put plastic under the gas cap earlier, make sure to remove it
now.

Adjustments
Shift Lever Cable
Periodic adjustment of the six speed shift cable may be necessary
due to normal wear on the cable. Adjustment is needed if all six
speeds do not work. The adjustable cable bracket is located on
the left side of the mower beside the engine. See Fig. 6-3.

See Fig. 6-3.
Push back on the adjustable cable bracket.4.
Tighten hex nut.5.
Engine Care
A list of key engine maintenance jobs required for good
performance by the mower is given below. Follow the
accompanying engine manual for a detailed list and instructions.
Maintain oil level as instructed in engine manual.•
Service air cleaner every 25 hours under normal conditions. •
Clean every few hours under extremely dusty conditions.
Poor engine performance and flooding usually indicates
that the air cleaner should be serviced. To service the air
cleaner, refer to the engine manual.
Clean spark plug and reset the gap once a season. Spark •
plug replacement is recommended at the start of each
mowing season. Check engine manual for correct plug
type and gap specifications.
Clean engine regularly with a cloth or brush. Keep the •
top of the engine clean to permit proper air circulation.
Remove all grass, dirt, and combustible debris from muffler
area.

carefully fold the upper handle down toward the lower
handle as shown in Fig. 7-2.
Blade Care
WARNING: When removing the cutting blade for
sharpening or replacement, protect your hands with
a pair of heavy gloves or use a heavy rag to hold the
blade.
Periodically inspect the blade adapter for cracks, especially if you
strike a foreign object. Replace when necessary. Follow the steps
below for blade service.
Disconnect spark plug boot from spark plug. Turn mower 1.
on its side making sure that the air filter and the carburetor
are facing up.
Remove the bolt and the blade bell support which hold the 2.
blade and the blade adapter to the engine crankshaft. See

Replacing Fuse
The electric starter circuit and battery are protected by a 40
ampere fuse. If the fuse burns out, the electric starter will not
operate. If the unit fails to start with the electric starter, perform
the following steps to check the fuse inside the battery housing:
Open the battery cover as described in Replacing Battery. 1.
See Fig. 7-2.
Remove fuse from socket and inspect as shown in Fig. 7-5. 2.
If it is burned out, replace with standard automotive 40
ampere fuse.
Carefully place wiring back into housing, close battery 3.
cover, and fold upper handle back into place.
NOTE: The engine can be started manually if the fuse burns
out.
Off-Season Storage
The following steps should be taken to prepare your lawn mower
for storage.
Clean and lubricate mower thoroughly as described in the •
lubrication instructions.
Do not use a pressure washer or garden hose to clean your •
unit.
Coat mower’s cutting blade with chassis grease to prevent •
rusting.
Refer to engine manual for correct engine storage •
instructions.
Store mower in a dry, clean area. Do not store next to •
corrosive materials, such as fertilizer.
When storing any type of power equipment in a poorly
ventilated or metal storage shed, care should be taken to
rust-proof the equipment. Using a light oil or silicone, coat the
equipment, especially cables and all moving parts of your lawn
mower before storage.

workmanship for a period of three (3) years, commencing on the date
of original retail purchase or lease and will, at its option, repair or
replace, free of charge, any part found to be defective in materials or

items such as: belts, blades, blade adapters, grass bags and wheels.
Batteries have a one-year prorated limited warranty against defects in
material and workmanship, with 100% replacement during the first three
months. After three months, the battery replacement credit is based on
