SAFETY
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
1/2" 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 but move the
machine away from the area of spillage and avoid creating
any source of ignition until fuel vapors have dissipated.
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 chipper shredder: 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 all bystanders and pets at least 75 feet away. If you
are approached, stop the unit immediately.

SAFETY
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 for
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 roller housing,always make
sure the engine is switched off,the cutting roller is at a
complete standstill.
Move the machine at least 10 feet away from the refuel-
ing point before starting engine.
This chipper shredder 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
Do not force the machine.Use the correct machine for
your application. The correct machine will do the job
better and safer at the rate for which it is designed.
Do not change the engine governor settings or over-speed
the engine. The governor controls the maximum safe
operating speed of the engine.
Do not run the engine at a high speed when youare not
working.
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

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.

5. Pull the recoil starter until engine compression has
become difficult to pull. Let the recoil return to the home
position, then pull quickly to start the engine. Repeat
steps as needed. Fully open the choke and set the throt-
tle to the FAST position, before operating the unit.
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 the branch will self-feed more
efficiently.
If the chipper shredder stalls from overloading or clogging,
turn off the engine's power switch and wait until the
cutting roller is completely stopped . 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.
It is always advisable to process freshly cut materials, as
wooden branches get very hard, they become springy
when dried out and can make the knives dull more quickly.
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.
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.
The chipper shredder can process a wide variety of dry or
green organic materials such as branches, stalks, vines,
leaves, roots, and vegetable matter. The maximum
capacity is 3-inch diameter branches, this can vary
depending on the type and hardness of wood. Rotating
the branch as you feed it into the machine will improve
performance.
After the engine warms up, pull the throttle lever to accel-
erate engine speed.
Rapid retraction of the starter cord (kick-
back) will pull your handand arm toward
the engine faster than you can let go.
Broken bones, fractures, bruises, or
sprains could result.
Make sure the machine is level and stable
to avoid unnecessary vibrations.
Do not operate on concrete or other hard
surface.

OPERATION
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 movement by hand. To move the unit, grip
the handles and tilt the wood chipper slightly after
making sure the oil tank cover is tightened.
Wait until the machine completely stops. Allow the
engine to completely cool. Remove the engine's spark
plug. Then clean out the interior of the machine and its
discharge chute.
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.
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 open the housing cover unless the
engine and cutting roller are completely
stopped.
The engine is fitted with an oil alert and
will not start if the oil level in the sump is
too low. It may also stop if it is operated
on a steep slope.
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.
IDLE SPEED
STOP ENGINE
1. Move the throttle lever to the SLOW ( ) position.
2.Let the engine idle for one or two minutes.

2. Keep the engine's throttle lever in its SLOW position
and remove the spark plug wire from the spark plug and
secure.
3. Inspect the general condition of the chipper shredder.
Check for loose screws, misalignment or binding of
moving parts, cracked or broken parts, and any other
condition that may affect its safe operation.
4. Remove all debris from the Wood chipper with a soft
brush, vacuum, or compressed air. Then use a premium
quality lightweight machine oil to lubricate all moving
parts.
The service intervals shown are the maximum
under normal operating conditions. Increase
frequencies under extremely dirty or dusty condi-
tions.
5. Replace the spark plug wire.
Maintaining your Wood chipper will ensure long life to the
machine and its components.
Never use a pressure washer to clean your
Wood chipper. Water can penetrate tight
areas of the unit and cause damage to
spindles, pulleys, bearings, or the engine.
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.

MAINTENANCE
If the machine's cutting roller 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 roller
to come to a complete stop. Switch the engine to
"off" to avoid any accidental start. Then perform
the following steps:
Routine inspection of the knives for sharpness and wear
plate for a sharp edge will ensure that your wood chipper
is operating at full efficiency. Using dull knives or a round-
ed wear plate will decrease performance and cause
excessive vibration that will damage the machine and
make chipping difficult for the operator.
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 knifes by following
steps.
4. 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.
KNIFE AND WEAR PLATE INSPECTION
KNIFE REMOVAL AND REPLACEMENT
1. Remove the feed hopper.
2. Rotate the cutting disc until the blade can be seen from
the feed hopper side.
Inspect for damage.
Repair оr replace damaged parts.
Check for any loose parts and tighten to ensure
continued safe operation.
3. Remove the bolts, nuts that fix the blade.
20
www. mechmaxx.com
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.
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 chipper shredder 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 con tent 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 chipper shredder in an upright position in a
clean, dry building with good ventilation.
The clearance between the knives and wear plate should
be approximately 1 mm at the position of closest to the
rotor shaft and 3 mm 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.
