Troubleshooting - Craftsman 536.797480 Owner's Manual

i
• To remove gasoline, run the engine
until the tank is empty and the engine
stops.
• If you do not want to remove gasoline
a fuel stabilizer (such as 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 container. Then run engine at
least 10 minutes after stabilizer is added
to allow mixture to reach carburetor.
Store edger/trimmer in a safe place. See
IMPORTANT under STORAGE (EN-
GINE).
• Store the edger/trimmer in the wheels-
down, operating position. If the edger/
trimmer is stored in any other position, oil
from the crankcase could enter the
cylinder, causing a service problem.
You can keep your engine in good operating
condition during storage by:
• Changing oil.
• Lubricating the piston/cylinder area.
This can be done by first removing the
spark plug and squirting clean engine
oil into 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.
