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 10. With chipper-shredder level,
use a funnel to fill engine with oil to FULL mark on
dipstick. Capacity is approximately 1-1/4 pints. Be
careful not to overfill. Tilt chipper-shredder toward
the left (from behind the hopper), then re-level.
Check oil level. Refill to FULL mark on dipstick if
necessary. Replace dipstick and tighten.
SAE30
FIGURE 9.
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.
GAS
• Remove fuel cap and fill fuel tank with about 1-7/8
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 CHIPPERSHREDDER 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-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.
SEE “STORAGE” SECTION FOR ADDITIONAL
INFORMATION.
