and remove the air
filter.
As
the generator set runs out of fuel, squirt
fogger into the carburetor intake, then reassemble
the air filter.
When generator set runs out of fuel and stops run-
ning, remove the spark plug. Squirt one tablespoon
(about
30
mi) of clean engine oil into the spark plug
hole. Turn the engine over for several revolutions.
Replace the spark plug. Pull the recoil starter han-
dle out slowly until compression is felt
Drain the oil base while still warm. Refill the crank-
caseand attach atag indicating viscosity of oil used.
Hot
oil can Cause severe bums if

spilled
or
splashed on skin.
Keep fingers
and
hands clear when removing oil
drain plug, and wear protective clofhing.

low,
charge until correctvalue is obtained. If level is low
add distilled water and charge until specific gravity
is correct.
