ing material in the chipper chute or shredder hopper,
8. Never place your hands, feet, or any part of your body into the
shredder hopper, chipper chute, discharge opening, or near
any moving part while the engine is running. Keep clear of the
discharge opening at all times. If it becomes necessary to
push material into the chipper chute or shredder hopper, use a
small diameter stick, NOT YOUR HANDS.
9. If it is necessary for any reason to unclog the feed intake or
discharge openings or to inspect or repair any part of the
machine where a moving part can come in contact with your
body or clothing, stop the machine, allow it to cool, disconnect
the spark plug wire from the spark plug and move it avi?ay from

which could cause you to stumble and fall. Do not overreach,
Maintaining proper footing and balance is essential to prevent
ing accidents.
12. Do not allow an accumulation of processed material to build
up in the discharge area as this will prevent proper discharge
and can result in kick-back from the chipper chute.
13. Keep your face and body back from chipper chute to avoid
accidental bounce back of any material.
14. Do not transport machine while engine is running.
15. If the cutting mechanism strikes a foreign object or if your

or in dark areas where your vision may be impaired.
II. CHILDREN
^Tragic accidents can occur if the operator is not alert to the pres
ence of small children. Children are often attracted to the chipper
shredder and the chipping and shredding activity. Never assume
that children will remain where you last saw them.
1. Keep children out of the work area and under the watchful eye
of a responsible adult other than the operator.
2. Be alert and turn the unit off if a child enters the area.
3. Never allow children under the age of 16 to operate the chip
per-shredder.
III. SERVICE
k 1, Use extreme care in handling gasoline and other fuels. They
are extremely flammabie and the vapors are explosive.
a. Store fuel and oil in approved containers, away from heat
and open flame, and out of the reach of children. Check
and add fuel before starting the engine. Never remove gas
cap or add fuel while the engine is running. Allow engine
to cool at least two minutes before refueling.
b. Replace gasoline cap securely and wipe off any spilled
gasoline before starting the engine as it may cause a fire
or explosion.
c. Extinguish all cigarettes, cigars, pipes and other sources
of ignition.
d. Never refuel unit indoors because flammable vapors will
accumulate in the area.
e. Never store the machine or fuel container inside where
there is an open flame or spark such as a gas hot water
heater, space heater, clothes dryer or furnace.
2. Never run your machine in an enclosed area as the exhaust
from the engine contains carbon monoxide, which is an odor
less, tasteless and deadly poisonous gas.
3. To reduce fire hazard, keep engine and muffler free of leaves,
grass, and other debris build-up. Clean up fuel and oil spillage.
Allow unit to cool at least 5 minutes before storing.
4. Before cleaning, repairing, or inspecting, make certain the
impeller and ali moving parts have stopped. Disconnect the
spark plug wire and keep wire away from spark plug to prevent
accidental starting, Do not use flammable solutions to clean
air filter.
5. Check the blade and engine mounting screws at frequent inter
vals for proper tightness. Also visually inspect blades for wear
and/or damage (e.g., bent, cracked). Replace with biades
which meet original equipment specifications.
6. Keep all nuts, bolts, and screws tight to be sure the equipment
is in safe working condition.
7. Never tamper v;ith safety devices. Check their proper opera
tion regularly.
8. After striking a foreign object, Immediately stop the engine,
disconnect the spark plug wire from the spark plug, and thor
oughly inspect the unit for any damage. Repair damage before
starting and operating unit.
9. Do not alter or tamper vdth the engine’s governor setting. The
governor controls the maximum safe operating speed of the
engine. Over-speeding the engine is dangerous and will cause
damage to the engine and to other moving parts of the

WARNING: MAKE CERTAIN THE CHIP
PER CHUTE DOOR IS CLOSED WHEN
A
NOT IN USE.
5W30
NOTE: Although multi-viscosity oils (5W30, 10W30,
etc.) improve starting in cold weather, these multi
viscosity oils will result in increased oil consumption
when used above 32°F. Check your oil level more fre
quently to avoid possible engine damage from run
ning low on oil.
• Fill engine with oil as follows. Remove oil fill dip
stick. See figure 12. With chipper-shredder level,
use a funnel to fill engine with oil to FULL mark on
dipstick. Capacity is approximately 21 ounces. Be
careful not to overfill. Tilt chipper-shredder toward

necessary. Replace dipstick and tighten.
SAE 30
IMPORTANT: There is a flail screen located inside
the housing in the discharge area. If the flail screen
becomes clogged, remove and clean as instructed in
the Service and Adjustments section. For best per
formance, it is important to keep the shredding blade
and the chipper blades sharp. If the composition of
the material being discharged changes (becomes
stringy, etc.) or if the rate at which the material Is dis
charged slows down considerably, it is likely that the
shredding blade and/or chipper blades are dull and
need to be sharpened or replaced. Refer to Service
and Adjustments section.
FIGURE 12.
GAS
• Remove fuel cap and fill fuel tank with about 3
quarts of clean, fresh, lead-free grade automotive
gasoline. DO NOT use Ethyl or high octane gaso
line. Be certain container is clean and free from
rust or foreign particles. Never use gasoline that
may be stale from long periods of storage in the
container. Replace fuel cap.
WARNING: DO NOT FILL CLOSER THAN
1/2 INCH OF TOP OF FUEL TANK TO
A
PREVENT SPILLS AND TO ALLOW FOR
FUEL EXPANSION. IF GASOLINE IS
ACCIDENTLY SPILLED, MOVE CHIPPER
SHREDDER AWAY FROM AREA OF
SPILL. AVOID CREATING ANY SOURCE
OF IGNITION UNTIL GASOLINE VAPORS
HAVE DISAPPEARED.
10
Check the fuel level periodically to avoid running out
of gasoline while operating the chipper-shredder, if the
unit runs out of gas as it is shredding or chipping, it
may be necessary to unclog the unit before it can be
restarted. Refer to “Removing the Flail Screen” in
SERVICE AND ADJUSTMENT section.
WARNING: EXPERIENCE INDICATES THAT ALCO
HOL BLENDED FUELS (CALLED GASOHOL OR
USING ETHANOL OR METHANOL) CAN ATTRACT
MOISTURE WHICH LEADS TO SEPARATION AND
FORMATION OF ACIDS DURING STORAGE.
ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM
OF AN ENGINE WHILE IN STORAGE. TO AVOID
ENGINE PROBLEMS, THE FUEL SYSTEM
SHOULD BE EMPTIED OR TREATED WITH FUEL
STABILIZER BEFORE STORAGE FOR 30 DAYS
OR LONGER. USE FRESH FUEL NEXT SEASON.

5W30
32“F
SAE30
NOTE: Although multi-viscosity oils (SE30, 10W30,
etc.) improve starting in cold weather, these multi- vis
cosity oils will result in increased oil consumption
when used above 32“F. Check your oil level more fre
quently to avoid possible engine damage from run
ning low on oil.
Your four-cycle engine will normally consume some
oil—therefore, check engine oil level regularly approx
imately every five hours of operation and before each
usage. Stop engine and wait several minutes before
checking oil level. With engine level, the oil must be to
FULL mark on dipstick (refer to figure 12). Change
engine oil after the first five hours of operation, and
every twenty-five hours thereafter.
To Drain Oil:
• Drain oil while engine is warm.
a. Remove oil drain plug. Refer to figure 12. Catch
oil in a suitable container.
b. When engine is drained of all oil, replace drain
plug securely.
• Refill with fresh oil. Refer to GAS AND OIL FILL
UP section.
• Replace dipstick.
