GAS
• Remove fuel cap and fill fuel tank with approxi­
mately 3 quarts of clean, fresh, lead-free grade
automotive gasoline. DO NOT use Ethyl or high
octane gasoline. Be certain container is clean and
free from rust or foreign particles. Never use gaso­
line that may be stale from long periods of storage
in the container. Replace fuel cap.
A
WARNING: DO NOT FILL CLOSER THAN
1/2 INCH OF TOP OF FUEL TANK TO
PREVENT SPILLS AND TO ALLOW FOR
FUEL EXPANSION. IF GASOLINE IS
ACCIDENTLY SPILLED, MOVE CHIPPER-
VACUUM AWAY FROM AREA OF SPILL.
AVOID CREATING ANY SOURCE OF
IGNITION UNTIL GASOLINE VAPORS
HAVE DISAPPEARED.
Check the fuel level periodically to avoid running out
of gasoline while operating the chipper-vacuum. If the
unit runs out of gas as it is chipping, it may be neces­
sary 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.
SEE “STORAGE” SECTION FOR ADDITIONAL
INFORMATION.
NEVER USE ENGINE OR CARBURETOR CLEAN­
ER PRODUCTS IN THE FUEL TANK OR PERMA­
NENT DAMAGE MAY OCCUR.
USING THE CHIPPER CHUTE
NOTE: Do not try to chip any material other than veg­
etation like branches, leaves, twigs, etc., in a normal
yard. Such materials of up to 3" diameter may be fed
into the chipper chute. See figure 13.
FIGURE 13.
A
WARNING: DO NOT FEED ANY MATERI­
AL
MORE THAN 3" DIAMETER
VEGETATION INTO THE CHUTE. PER­
SONAL INJURY AND/OR DAMAGE TO
THE UNIT COULD RESULT IF YOU TRY
TO FEED ANY MATERIAL OTHER THAN
SPECIFIED HERE.
If necessary, use the tamper plug to push the
material into the chipper chute. See figure 8 for the
location of the tamper plug.
Place tamper plug inside the chute when not in use
to deaden the noise.
A
WARNING: NEVER PLACE
INSIDE THE CHIPPER CHUTE.
HANDS
• For best performance, keep the chipper blades
sharp.
• If the discharged material starts to become stringy,
or if the rate of discharge slows down considerably,
the chipper blades may have become dull. To
sharpen or replace the blade, refer to Service and
Adjustment section.
• If the flail screen, located inside the housing in the
discharge area, becomes clogged, remove the
screen and clean. For instructions on cleaning the
screen, refer to the Service and Adjustment sec­
tion.
