ENGINE
Refer to the separate engine manual for engine
maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and
follow instructions carefully.

conditions. Clean every few hours under extremely
dusty conditions. Poor engine performance and
flooding usually indicates that the air cleaner should
be serviced. To service the air cleaner, refer to the
separate engine manual packed with your unit.
The spark plug should be cleaned and the gap
reset once a season. Spark plug replacement is
recommended at the start of each season; check
engine manual for correct plug type and gap
specifications.
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area)
clean to permit proper air circulation which is
essential to engine performance and life. Be certain
to remove all dirt and combustible debris from
muffler area.
