A WARNING: PERIODICALLY CLEAN MUF­
FLER AREA TO REMOVE ALL GRASS,
DIRT AND COMBUSTIBLE DEBRIS.
CLEANING
• The chipper-shredder may be cleaned by running
water from a hose through the hopper assembly
and chipper chute with the engine running. Allow
the chipper-shredder to dry thoroughly.
• Wash the bag periodically with water. Allow to dry
thoroughly in the shade. Do not use heat.
Clean Out
Chaff and Dirt
FIGURE 11.
SPARK PLUG
The spark plug should be cleaned and the gap reset
to .030" at least once a season or every 50 hours of
operation. See figure 12. Spark plug replacement is
recommended at the start of each season. 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.
MUFFLER
Do not operate the chipper-shredder without a muffler
or tamper with the exhaust system. Damaged mufflers
or spark arresters could create a fire hazard. Inspect
periodically, and replace if necessary. If your engine
is equipped with a spark arrester screen assembly,
remove every 50 hours for cleaning and inspection.
Replace if damaged.
STORAGE
Prepare your chipper-shredder for storage at the end
of the season or if the unit will not be used for 30 days
or more.
A WARNING: NEVER STORE MACHINE
WITH FUEL IN THE FUEL TANK INSIDE
OF BUILDING WHERE FUMES MAY
REACH AN OPEN FLAME OR SPARK, OR
WHERE IGNITION SOURCES ARE
PRESENT SUCH AS HOT WATER AND
SPACE HEATERS, FURNACES, CLOTHES
DRYERS, STOVES, ELECTRIC MOTORS,
ETC.
NOTE: A yearly check-up by your local Sears Service
Center is a good way to make certain your chipper­
shredder will provide maximum performance for the
next season.
CHIPPER-SHREDDER
• Clean the chipper-shredder thoroughly.
• Wipe unit with an oiled rag to prevent rust (use a
light oil or silicone).
ENGINE
IMPORTANT: IT IS IMPORTANT TO PREVENT
GUM DEPOSITS FROM FORMING IN ESSENTIAL
FUEL SYSTEM PARTS SUCH AS CARBURETOR,
FUEL FILTER, FUEL HOSE, OR TANK DURING
STORAGE. ALSO, EXPERIENCE INDICATES THAT
ALCOHOL BLENDED FUELS (CALLED GASOHOL
OR USING ETHANOL OR METHANOL) CAN
ATTRACT MOISTURE WHICH LEADS TO SEPARA­
TION AND FORMATION OF ACIDS DURING STOR­
AGE. ACIDIC GAS CAN DAMAGE THE FUEL SYS­
TEM OF AN ENGINE WHILE IN STORAGE.
• Drain the fuel tank.
• Start the engine and let it run until the fuel lines and
carburetor are empty.
• Never use engine or carburetor cleaner products in
the fuel tank or permanent damage may occur.
• Use fresh fuel next season.
