GENERAL SAFETY RULES
SAFETY
Read this manual and labels affixed to the machine to
understand its limitations and potential hazards.
Be thoroughly familiar with the controls and their proper
operation. Know how to stop the machine and disengage
the controls quickly.
Make sure to read and understand all the instructions and
safety precautions as outlined in the Engine Manufactur-
er's manual packed separately with your unit. Do not
attempt to operate the machine until you fully understand
how to properly operate and maintain the engine and how
to avoid accidental injuries and/or property damage.
If the unit is loaned, rented, sold, or used by someone
other than the original purchaser, provide this manual and
safety training before operation. The user can prevent and
is responsible for accidents or injuries that may occur to
themselves, other people, and property
Always use the correct machine for your job. Forcing the
machine may cause damage. The correct machine will do
the job more efficiently and safely at the rate it was
designed.
Always keep hands and feet away from all moving parts
during operation. Moving parts can cut or crush body
parts.
Do not touch parts that might be hot from operation.
Allow parts to cool before attempting to maintain, adjust,
or service.
Do not overreach. Do not operate the machine while
barefoot or when wearing sandals or similar lightweight
footwear. Wear protective footwear that will protect your
feet and improve your footing on slippery surfaces. Keep

This machine is equipped with an internal combustion
engine. Do not use on or near any unimproved, forest
covered, or brush covered land unless the exhaust system
is equipped with a spark arrester meeting applicable
local, state, or federal laws.
Never start or run the engine inside a closed area. The
exhaust fumes are dangerous, containing carbon monox-
ide, an odorless and deadly gas. Operate this unit only in a
well-ventilated outdoor area.
Do not tamper with the engine to run it at excessive
speeds. The maximum engine speed is preset by the
manufacturer and is within safety limits. See engine
manual.
Keep a Class B fire extinguisher on hand when operating
this Wood chipper in dry areas as a precautionary
measure.
Fuel is highly flammable, and its vapors can explode if
ignited. Take precautions when using to reduce the
chance of serious personal injury.
When refilling or draining the fuel tank, use an approved
fuel storage container while in a clean, well-ventilated
outdoor area. Do not smoke, or allow sparks, open flames,
or other sources of ignition near the area while adding fuel
or operating the unit. Never fill the fuel tank indoors.
Keep grounded conductive objects, such as tools, away
from exposed, live electrical parts and connections to
avoid sparking or arcing. These events could ignite fumes
or vapors.
Always stop the engine and allow it to cool before filling
the fuel tank. Never remove the cap of the fuel tank or
add fuel while the engine is running or when the engine is
hot. Do not operate the machine with known leaks in the
fuel system.
Never overfill the fuel tank. Fill the tank to no more than
½ inch below the bottom of the filler neck to provide
space for expansion as the heat of the engine can cause
fuel to expand.
Replace all fuel tank and container caps securely and
wipe up spilled fuel. Never operate the unit without the
fuel cap securely in place.
Loosen the fuel tank cap slowly to relieve any pressure in
the tank.
Avoid creating a source of ignition for spilled fuel. If fuel
is spilled, do not attempt to start the engine; instead,
move the machine away from the spillage area and avoid
creating ignition sources until vapors dissipate.
When fuel is spilled on yourself or your clothes, wash your
skin and change clothes immediately.
Store fuel in containers specifically designed and
approved for this purpose.
Store fuel in a cool, well-ventilated area, safely away from
sparks, open flames, or other sources of ignition.
Never store fuel or a machine with fuel in the tank inside
a building where fumes may reach a spark, open flame, or
any other source of ignition, such as a water heater,
furnace, or clothes dryer. Allow the engine to cool before
storing in any enclosure.
Identify hazards and take preventive steps to avoid
accidents and minimize risk. Possible hazards include,
but are not limited to, moving parts, thrown objects,
weight of the machine and components, and the operat-
ing environment.
Thoroughly inspect the area in which you are working,
keeping it clean and free of debris to prevent tripping.
Operate on a flat level ground.
Before starting your wood chipper: make sure the feed
hopper and cutting housing are empty and free of all
debris, check the oil level, make sure all nuts and bolts
are tight, and check the air pressure in the tires.
Never place any part of your body where it would be in
danger if movement should occur during assembly, instal-
lation, operation, maintenance, repair, or moving.
Never place your hands, feet, or any part of your body in
the chipper hopper, discharge opening, or near or under
any moving part while the machine is running. Keep the
area of discharge clear of people, animals, buildings,
glass, or anything else that will obstruct clear discharge,
causing injury or damage. Wind can also change
discharge direction, so be aware. If it becomes necessary
to push materials to the chipper hopper, use a small-di-
ameter stick, not your hands.
Keep bystanders and pets at least 75 feet away from the
discharge chute and feed hopper.

SAFETY
OPERATING ZONE
www.mechmaxx.com
Keep your face and body back from the chipper hopper and
discharge chute to avoid injury from accidental bounce
back of material.
Feed only clean materials into the machine. Foreign
matter such as soil, sand, grit, stones, pieces of metal,
etc. will damage the sharp edge of the cutting knives.
Root balls and dead wood will also dull the blades quickly
Avoid feeding pine needles, flax and cabbage tree leaves
into the machine; these stringy materials can wrap
around the rotor shaft and work their way into the bearing.
Avoid feeding short, stubby pieces of wood into the
machine; they tend to bounce and spin in the feed hopper.
Feed these short pieces together with longer pieces.
After becoming familiar with the machine, prune to suit
its capabilities.
This machine is self-feeding, do not force branches into
the blades. Allow the machine to automatically feed
through. Allow time for the machine to reach the highest
spinning revolutions before feeding the next load of
branches.
Never allow processed material to build up in the
discharge area. This can prevent proper discharge and
result in kickback from the chipper hopper.
Never attempt to unclog either the feed hopper or
discharge chute while the engine is running. Immediately
shut off the engine, allow the cutting disk to come to a
complete stop, and then remove the clogged material.
Inspect for damage and check for any loose parts that
need repair or replacement.
Whenever you leave the operating position or if you have
to remove processed material, leaves, or debris from the
machine, always shut down the engine, and ensure the
engine is switched to“off” to prevent accidental starting,
and wait for all moving parts to come to a complete stop.
Before opening the cutting disk housing, always make
sure the engine is switched off, the cutting disk is at a
complete standstill, and the belt drive is disengaged.
Move the machine at least 10 feet away from the refuel-
ing point before starting engine.
This wood chipper is for movement by hand only. Never
attempt to tow the machine on public highways, roads, or
thoroughfares.
Position the machine in such a way that it can not move
during maintenance,cleaning, adjustment, assembly of
accessories or spare parts, as well as under storage.
Always use the correct machine for your job. Forcing the
machine may cause damage. The correct machine will do
the job better and safer at the rate for which it is
designed.
Do not adjust the engine governor settings or operate the
engine above the recommended speed. The governor
controls the maximum safe operating speed of the
engine.
Always stop the engine before moving the machine, and
watch out for sharp objects that could pierce the tires.
Never reach with your hands inside the feed hopper past
the rubber flap while operating the machine.
Keep combustible substances away from the engine
when it is hot.
Do not tilt the machine while the engine is running
Never operate this machine without the feed hopper or
discharge chute properly attached.

3. Using a funnel, add oil up to the FULL mark on the
dipstick. (See engine manual for oil capacity, oil recom-
mendation, and location of fill cap.).
1. The engine must be off and
allowed to cool at least two
minutes before adding fuel.
2. Remove the fuel filler cap
and fill the tank. (See engine
manual for fuel capacity, fuel
recommendation, and location
of fuel cap.)
The engine is shipped without oil. Do not
start the engine before adding oil.
DO NOT OVERFILL. Check engine oil level
daily and add as needed.
This equipment and/or its engine may
include evaporative emissions control
system components, required to meet
EPA and/or CARB regulations, that will
only function properly when the fuel tank
has been filled to the recommended level.
Overfilling may cause permanent damage
to evaporative emissions control system
components. Filling to the recommended
level ensures a vapor gap required to
allow for fuel expansion. Pay close atten-
tion while filling the fuel tank to ensure
that the recommended fuel level inside
the tank is not exceeded. Use a portable
gasoline container with an appropriately
sized dispensing spout when filling the
tank. Do not use a funnel or other device
that obstructs the view of the tank filling
process.
Gasoline is highly flammable and explo-
sive. You can be burned or seriously
injured when handling fuel. Use extreme
care when handling gasoline.
Fill the fuel tank outdoors, never indoors.
Gasoline vapors can ignite if they collect
inside an enclosure. Explosion can result.

The wood chipper can process a wide variety of dry and
green organic materials, including branches, stalks, vines,
leaves, roots, and vegetable matter. The maximum capac-
ity is 8-inch diameter branches, though this may vary
depending on the type and hardness of the wood. Rotating
the branch as you feed it into the machine can improve
performance.
After the engine warms up, pull the throttle lever to accel-
erate engine speed.
OPERATING
Feed limbs or branches through cut-end first, leaving the
bushy head on. This helps guide the limb down the feed
hopper and reduces spinning and bouncing of small pieces
back up the feed hopper. Some side branches may require
pre-cutting so that they self-feed more efficiently.
It is always advisable to process freshly cut materials, as
wooden branches become springy and dull knives more
quickly when dried out.
While operating the machine, keep a wooden stick handy,
approximately 1 inch in diameter by 2 feet long. This stick
will be useful to push in short, brushy and very leafy mate-
rials and keep the feed hopper clear.
17
OPERATION
www.mechmaxx.com
Do not force material into the machine. If it does not chip
well, the chipper knives may need sharpening or to be
replaced, or the gap between the knives and the wear
plate needs adjusting.
Do not overload the machine by feeding too much material
in to the feed hopper at one time. If you hear the speed of
the engine decreasing, immediately stop feeding material
in to the machine. Do not resume feeding material into the
machine until the engine has returned to full speed.
The wood chipper can clog up with soft, wet, or fibrous
materials. However, if you feed soft materials intermit-
tently with branches, there should be no problem, as the
wood chipper tends to clean out any residue left in the
machine.
If any stringy material wraps around the rotor shaft,
remove it before it works its way into the bearing.
If the wood chipper stalls due to overloading or clogging,
turn off the engine switch and wait until the cutting disk
is completely stopped and the belt drive is disengaged.
Allow the engine to completely cool and switch the engine
to off. Open the housing cover to clear and remove all the
materials from the housing. Lock the housing cover,
switch the engine to the on position, and start the
machine again to resume operation.
As the discharge material plies up, move the chipper away
from the pile. This will keep the material from backing up
the discharge chute. Do not position the deflector
vertically, as this will reduce the airflow, impeding the
discharge and causing blockage.
Make sure the machine is level and stable
to avoid unnecessary vibrations.
Do not open the housing cover unless the
engine and cutting disk are completely
stopped and the belt drive is disengaged.
To shut down the machine, move the
throttle control lever to idle speed, turn
the engine switch to the OFF position, and
it will gradually come to a standstill.
Set the throttle control lever to the SLOW position to
reduce stress on the engine when chipping is not being
performed. Lowering the engine speed will help extend the
life of the engine, as well as conserve fuel and reduce
noise level.
IDLE SPEED
To stop the engine in an emergency, simply turn the
engine switch to the OFF position. Under normal condi-
tions, use the following procedure:
Your wood chipper is equipped with two large pneumatic
wheels for easy maneuverability. To move the unit, grip
the handles and tilt the wood chipper slightly, ensuring
that the oil tank cover is securely tightened beforehand.
Wait until the machine completely stops. Allow the
engine to completely cool. Then clean out the interior of
the machine and its discharge chute.
Sudden stopping at a high speed under a
heavy load is not recommended. Engine
damage may result.
Do not move the choke control to CLOSE
to stop the engine. Backfire or engine
damage may occur.
Do not disengage the belt drive with the
machine running. This will cause friction
and vibration on the belt drive.
STOP ENGINE
1. Move the throttle lever to the SLOW ( ) position.
2. Let the engine idle for one or two minutes.
3. Turn the engine switch to the OFF position.
4. Turn the fuel valve lever to the OFF ( ) position.

Shut down the engine, wait for all moving
parts to come to a complete stop, remove
the spark plug wire, and then wait five
minutes before performing maintenance
on the chipper.
PREVENTIVE MAINTENANCE
1. Turn off the engine. The engine must be cool.
REGULAR MAINTENANCE CHECKLIST
19
MAINTENANCE
www.mechmaxx.com
Routinely inspect both the knives (for sharpness) and the
wear plate (for edge condition) to ensure that your wood
chipper is operating at full efficiency. Using dull knives or
a rounded wear plate will decrease performance and
cause excessive vibration that will damage the machine
and make chipping difficult for the operator.
KNIFE AND WEAR PLATE INSPECTION
If the machine's cutting disk strikes a foreign
object, or if the machine begins to make an
unusual noise or vibrates excessively, immedi-
ately shut off the engine. Allow the cutting disk
to come to a complete stop. Switch the engine to
"off" to avoid any accidental start. Then perform
the following steps:
Inspect for damage.
Repair or replace damaged parts.
Check for any loose parts and tighten to ensure
continued safe operation.
There are two bearings, one outside and the
other inside the housing . The bearings are
greased when they are new, but it is recommend-
ed to grease them after a couple hours of use.
One or two pumps is sufficient. Be careful not to
over grease. Over lubrication can damage the
bearings.
Grease the outside bearing
1. Open the plastic oil plug.
2. Grease the outside bearing through the filling hole.
3. Close the plastic oil plug.
1. Loosen the lock nut which holds the discharge chute
on the machine.
2. Slide down the fixing plate under the lock nut.
Grease the inside bearing
3. Open, then grease the inside bearing.

The clearance between the knives and wear plate should
be approximately 0.04 inch at the position of closest to
the rotor shaft and 0.12 inch at the position of farthest to
the rotor shaft. They are tapered out slightly to allow for a
small amount of movement in the cutting disk as it bites
into the wood.
Make sure that all locknuts are tightened properly. Then
turn the cutting disk with a long wooden stick to make
sure it rotates freely.
BELT ADJUSTMENT
fig.1
The belt on your chipper should deflect 3/8 in. under 10 lb
of pressure, as shown in Figure 1 below.
If it does not, adjust the belt tension according to the
following instructions.
1.
2.
3.
4.
5.
6.
Remove belt guard.
Loosen engine bolts.
Tighten or loosen the nut until you have the correct
tension as shown in fig. 1.
Retighten engine bolts.
Check alignment of the clutch with the drive pulley by
placing a straight edge across both faces as shown in
fig. 2. If adjustment is necessary, correct alignment
by moving rotor pulley in or out on the rotor shaft. Do
not make adjustment by moving the clutch on the
engine shaft.
Replace belt guard.
If the cutting disk surface is not cleaned
properly and the knives are not mounted
flush on the cutting disk, the knives could
crack when the hardware is tightened.
5. Remove the dull or damaged knives and visually
inspect the cutting disk slot and knives mounting area.
Make sure they are clean and that the placement knives
will be able to mount flush against the cutting disk.
Remount new or sharpened knives with the knife edges
facing up.
1. Remove the feed hopper.
Be careful and wear gloves when working
near the knives.
3. Rotate the cutting disc until the blade can be seen
from the feed hopper side.
2. Remove the discharge chute.
4. Remove the bolts, nuts that fix the blade.
KNIFE REMOVAL AND REPLACEMENT
This Wood chipper is equipped with two chipper knives
mounted on the cutting disk. When the knives get dull or
show visible nicks, the machine will lose its self- feeding
action and the material has to be pushed in. Often it
comes out in long strips. Replace the knives by following
steps.

NOTE: Check and re-tighten belts after
initial break-in period, one hour of use.
BELT REPLACEMENT
To replace the belt, follow the belt adjustment direc-
tions above.
After loosening the engine bolts, remove the old belts
and replace them with new ones. Always replace both
belts, as they come in a matched set. This is required
for proper operation.
Set the belt tension and alignment according to the
instructions above.
CENTRIFUGAL CLUTCH TECH TIPS
The shoes and springs on the clutch are normal wear
items. If you notice decreased performance of the clutch,
they should be checked and replaced if necessary.
The clutch on your machine is designed for rugged,
dependable service. However, it is important to under-
stand the limitations of a clutch. A clutch is designed to
provide load-free starting of the engine and allow slippage
under excessive overloading of the driven application.
These features help protect the engine from damage,
such as broken crankshafts and starters.
The clutch obtains its power from engine RPMs. The lower
the engagement speed and the higher the maintained
engine speed, the more torque the clutch can transfer to
the driven unit. Do not operate at less than full RPMs.
At engine start-up, your chipper's engine operates under
no load until approximately 1,000–1,200 RPMs, at which
point the centrifugal clutch engages and begins driving
the rotor.
The proper rotor speed is 2,200 RPM ± 200 RPM when the
engine is at full RPM.
Do not tamper with the engine's governor setting. The
governor controls the maximum safe operating speed and
protects the engine. Over-speeding the engine is danger-
ous and will cause damage to the engine and other
moving parts of the machine. See your authorized dealer
for engine governor adjustments.
Become familiar with successful operating conditions
and avoid those that can overload or damage the
machine.
Do not overload or attempt to chip material beyond the
manufacturer's recommendation. Personal injury or
machine damage could result.
Learn to recognize the sound of the machine when it is
overloaded. If the machine becomes jammed due to
overloading or any other cause, stop the machine immedi-
ately.
If the machine jams and the engine is not stopped, it can:
Burn the belt.
Ruin the clutch.
Only operator experience will determine how quickly you
can successfully feed limbs into the machine.
Clutch damage can be costly and is not covered under
warranty. For this reason, immediately shut off the
machine if it becomes jammed.

STORAGE
Remove the spark plug and drain all oil
from the cylinder before attempting to
start the unit after storage.
Do not use strong detergents or petroleum
based cleaners when cleaning plastic
parts. Chemicals can damage plastics.
Do not store your wood chipper with fuel
in a non-ventilated area where fuel fumes
could reach flames, sparks, pilot lights or
any ignition sources.
If your Wood chipper will not be used for more than 30
days, follow the steps below to prepare your unit for
storage:
1. Drain the fuel tank completely. Stale fuel has high
gum content and can clog the carburetor and restrict fuel
flow.
2. Start the engine and allow it to run until it stops. This
ensures no fuel is left in the carburetor and helps prevent
deposits from forming inside, which can damage the
engine.
3. Drain the oil from the engine while it is still warm.
Refill with fresh oil of the grade recommended in the
engine manual.
4. Allow the engine to cool. Remove the spark plug and
put 60 ml of SAE-30 high-quality engine oil into the cylin-
der. Pull the starter rope slowly to distribute the oil.
Replace the spark plug.
5. Use clean cloths to clean off the outside of the Wood
chipper and to keep the air vents free from obstructions.
6. Store your wood chipper in an upright position in a
clean, dry building with good ventilation.
Use only approved fuel containers.
