• Never operate unit without either the inlet nozzle or optional
hose attachment properly affixed to unit. These devices shield
the operator from accidental contact with the rotating impeller.
Never attempt to convert the unit from nozzle to hose mode or
vice versa with the engine running.
• Never attempt to remove or empty vacuum bag when engine is
running. Shut the engine off and wait for the impeller to come to
a complete stop before removing the bag. The impeller contin
ues to rotate for a few seconds after the engine is shut off.
Never place any part of the body in the impeller area until you
are sure the impeller has stopped rotating.
• Keep all guards and safety devices in place and operating prop
erly.
• 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.
• Keep your face and body back from chipper chute to avoid acci
dental bounce back of any material.
• If the cutting mechanism strikes a foreign object or if your
machine should start making an unusual noise or vibration,
immediately stop the engine, disconnect the spark plug wire and
move the wire away from the spark plug. Allow the machine to
stop and take the following steps.
• Inspect for damage
• Repair or replace any damaged parts.
• Check for any loose parts and tighten to assure continued
safe operation.
• Muffler and engine become hot and can cause a burn. Do not
touch.
• Do not allow leaves or other debris to build up on engine’s muf
fler. The debris could ignite and cause a fire.
• Do not operate engine if air cleaner or cover over carburetor airintake is removed, except for adjustment. Removal of such
parts could create a fire hazard.
Jl. CHILDREN
Tragic accidents can occur if the operator is not alert to the pres
ence of small children. Children are often attracted to the chipping
and vacuuming activity. Never assume that children will remain
where you last saw them.
• Keep children out of the work area and under the watchful eye of
a responsible adult other than the operator.
• Be alert and turn the unit off if a child enters the area.
• Never allow children under the age of 16 to operate the chippervacuum.
III. SERVICE
Use extreme care in handling gasoline and other fuels. They are
extremely flammable and the vapors are explosive.
• 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.
• Replace gasoline cap securely and wipe off any spilled
gasoline before starting the engine as it may cause a fire or
explosion.
• Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
• Never refuel unit indoors because flammable vapors will
accumulate in the area.
• Never store the machine or fuel container inside where
there is an open flame or spark such as a gas hot water
heater, clothes dryer or furnace.
• Never run your machine in an enclosed area as the exhaust from
the engine contains carbon monoxide, which is a odorless,
tasteless and deadly poisonous gas.
• 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.
• Before cleaning, repairing, or inspecting, make certain the
impeller and all 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.
Keep all nuts, bolts, and screws tight to be sure the equipment is
in safe working condition.
Never tamper with safety devices. Check their proper operation
regularly.
After striking a foreign object, immediately stop the engine, dis
connect the spark plug wire from the spark plug, and thoroughly
inspect the unit for any damage. Repair damage before starting
and operating unit.
Do not alter or tamper with 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 machine.
Check the vacuum bag frequently for wear. Replace if worn or
damaged.
Keep vacuum bag free of debris when not in use.

CUSTOMER RESPONSIBILITIES
GENERAL RECOMMENDATIONS
WARNING: ALWAYS STOP THE ENGINE
AND DISCONNECT THE SPARK PLUG
A
• Periodically check all fasteners and be sure they
are tight.
• Follow the Maintenance Schedule above.
WIRE BEFORE PERFORMING ANY
MAINTENANCE OR ADJUSTMENTS.
CHIPPER-VACUUM
LUBRICATION
Lubricate the pivot points on the height adjustment
mechanism once a season using a light oil.
CLEANING
• Clean the chipper-vacuum thoroughly after each
use.
• Wash the bag periodically with water. Allow to dry
thoroughly in the shade. Do not use heat.
ENGINE
ENGINE OIL
Only use high quality detergent oil rated with API
service classification SF, SG or SH. Select the oil’s
viscosity grade according to your expected operating
temperature.
Colder
5W30
NOTE: Although multi-viscosity oils (SE30, 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
frequently to avoid possible engine damage from
running 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 cooled down, the oil
level must reach 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 cap. Refer to figure 12. Catch
oil in a suitable container.
b. When engine is drained of all oil, replace drain
cap securely.
• Refill with fresh oil. Refer to GAS AND OIL FILL
UP section.
• Replace dipstick.

AIR CLEANER
The air cleaner prevents damaging dirt, du st, etc.,
from entering the carburetor, and being forced into the
engine. It is important to keep the engine clear to pro
long engine life and improve performance.
Never run your engine without air cleaner com
pletely assembled.
To Service Air Cleaner:
Service pre-cleaner after every 25 hours of us e, or at
least once a season. Replace filter every 100 hours of
use, or at least once a season. Service pre-clesner and
filter more often under dusty conditions.
• Remove wing nut and cover. See figure 16.
• Slide pre-cleaner off filter. Clean the inside of base
and cover thoroughly.
• Clean pre-cleaner as follows.
Wash in water and detergent solution, and £ queeze
(do not twist) until all dirt is removed.
Rinse thoroughly in clear water.
Wrap in a clean cloth and squeeze (do not twist)
until completely dry, or allow to air dry.
• If necessary, replace filter (do not attempt tc clean).
• Install new filter on base. Slide pre-dearer over
filter.
• Install cover and wing nut. Tighten w ng nut
securely.
CLEAN ENGINE
Clean engine periodically. Remove dirt and debris
with a cloth or brush. Cleaning with a forceful spray of
water is not recommended as water could contami
nate the fuel system.
Yearly or every 25 hours of using, whichever occurs
first, remove the air intake screen and blower
housing, and clean the areas shown in figure 17 to
avoid overspeeding, overheating and engine damage.
Clean more often if necessary.

SPARK PLUG
The spark plug should be cleaned and the gap reset
to .030" at least once a season or after every 50
hours of operation. See figure 18. Spark plug replace
ment is recommended at the start of each season.
Replace spark plug if electrodes are pitted, burned,
fouled with deposits, or porcelain is cracked. Refer to
engine parts list for correct spark plug type.
NOTE: Do not sandblast spark plug. Spark plug
should be cleaned by scraping or wire brushing and
washing with a commercial solvent.
