IMPORTANT: Used motor oil may cause skin cancer if repeatedly
left in contact with the skin for prolonged periods. Although this
is unlikely unless you handle used oil on a daily basis, it is still
advisable to thoroughly wash your hands with soap and water as
soon as possible after handling used oil.
NOTE: Please dispose of used motor oil in a manner that is
compatible with the environment. We suggest you take it in a
sealed container to your local service station for reclamation. Do
not throw it in the trash or pour it on the ground.
AirFilter Service
Paper filters cannot be cleaned and must be replaced once a year
or every 100 operating hours; more often if used in extremely
dusty conditions.
WARNING: Never use gasoline or low flash point
solvents for cleaning the air filter element. A fire or
explosion could result.
IMPORTANT: Never run the engine without the air filter. Rapid
engine wear will result.

rectangle paper filter with foam pre-filter or a single element
oval foam filter. The dual element type has a long rectangular
shaped air filter cover with a thumb screw towards the rear of
the engine to access the air filter elements. The single element
type has a short rectangular shaped air filter cover with a primer
on the air filter base at the front of the engine. Follow the
appropriate instructions below for the engine on your unit.
