STORAGE
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.
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
separation and formation of acids during storage.
Acidic gas can damage the fuel system 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 storage
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 carburetor 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 tablespoon) 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.
