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.
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.
NOTE: Fuel stabilizer is an acceptable
alternative in
minimizing the formation of fuel gum deposits during
storage. Add stabilizer to gasoline in fuel tank or stor-
age container.
Always follow the mix ratio found on
stabilizer container.
Run engine at least 10 minutes
after adding stabilizer to allow the stabilizer to reach
the carburetor. Do not drain the gas tank and carbure-
tor if using fuel stabilizer.
• Drain all the oil from the crankcase (this should be
done after the engine has been operated and is still
warm) and refill the crankcase with fresh oil.
• If you have drained the fuel tank, protect the inside
of the engine as follows. Remove spark plug, pour
approximately
1/2 ounce (approximately
one table-
spoon) of engine oil into cylinder and crank slowly
to distribute oil. Replace spark plug.
OTHER
• Do not store gasoline from one season to another.
• Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems.
• Store unit in a clean, dry area. Do not store next to
corrosive materials, such as fertilizer.
NOTE: If storing in an unventilated
or metal storage
shed, be certain to rustproof the equipment by coating
with a light oil or silicone.
SERVICE & ADJUSTMENT
WARNING: ALWAYS STOP ENGINE AND
DISCONNECT
SPARK PLUG WIRE AND
MOVE
IT AWAY
FROM
SPARK
PLUG
BEFORE
PERFORMING
ANY ADJUST-
MENTS OR REPAIRS.
REMOVING THE FLAIL SCREEN
If the discharge area becomes clogged, remove the
flail screen and clean area as follows.
• Stop the engine, make certain the chipper-shredder
has come to a complete stop and disconnect spark
plug wire from the spark plug before unclogging the
chute.
Loosen the two hand knobs on each side of the
chute deflector. Lift the chute deflector up, and tie it
out of the way.
Remove two hairpin clips from the clevis pins which
extend through
the housing.
Remove
the clevis
pins. Lift the flail screen from inside the housing.
See figure 19.
• Clean
the screen
by scraping
or washing
with
water. Reinstall the screen.
NOTE: Be certain to reassemble the flail screen with
the curved side down as shown in figure 19.
