STORAGE
▲
NEVER STORE YOUR CHIPPER-
SHREDDER INDOORS OR IN AN EN­
CLOSED, POORLY VENTILATED AREA IF
GASOLINE REMAINS IN THE TANK.
FUMES MAY REACH AN OPEN FLAME,
SPARK OR PILOT LIGHT FROM A
FURNACE, WATER HEATER, CLOTHES
DRYER, CIGARETTE, ETC.
To prevent engine damage if chipper-shredder is not
used for more than 30 days, follow the steps below.
NOTE: GASOLINE MUST BE REMOVED OR
TREATED TO PREVENT GUM DEPOSITS FROM
FORMING IN THE TANK, FILTER, HOSE AND CAR­
BURETOR DURING STORAGE. ALSO DURING
STORAGE, ALCOHOL-BLENDED GASOLINE THAT
USES ETHANOL OR METHANOL (SOMETIMES
CALLED GASOHOL) ATTRACTS WATER. IT ACTS
ON THE GASOLINE TO FORM ACIDS WHICH
DAMAGE THE ENGINE.
To remove gasoline, run engine until tank is empty and
engine stops. Then disconnect fuel line at carburetor
or fuel tank. Be careful not to damage fuel line, fittings
or fuel tank. Drain any remaining fuel from the system.
If you do not want to remove gasoline. Sears Craftsman
Fuel Stabilizer No. 33500 may be added to any gasoline
left in the tank to minimize gum deposits and acids. If
the tank is almost empty, mix stabilizer with fresh
gasoline in a separate container and add some to the
tank.
Always follow instructions on stabilizer con­
tainer. Then run engine at least 10 minutes after
stabilizer is added to allow mixture to reach car­
buretor. Store chipper-shredder in safe place. See
warning in previous column.
You can help keep your engine in good operating con­
dition during storage by:
• Changing oil.
• Lubricating the piston/cylinder area by first remov­
ing the spark plug and squirting clean engine oil in­
to the spark plug hole. Then cover the spark plug
hole with a rag to absorb oil spray. Next, rotate the
engine by pulling the starter two or three times.
Finally, reinstall spark plug and attach spark plug
wire.
Protect the chipper-shredder during storage by:
• Thoroughly cleaning the chipper-shredder.
• If storing in an unventilated or metal storage shed,
coat metal parts with a light oil or silicone to prevent
rust.
• Store in a clean, dry area.
