Engine
Refer to the separate engine manual for all engine
maintenance instructions.
1. Maintain engine oil as instructed in the separate
engine manual packed with your unit.
2. Service air cleaner every 25 hours under normal con-
ditions. Poor engine performance and flooding usually
indicate that the air cleaner should be serviced. To
service the air cleaner, refer to the separate engine
manual packed with your unit.
3. The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is recom-
mended at the start of each leaf blowing season.
4. Clean the engine regularly with a cloth or brush. Keep
the area around the engine clean to permit proper air
circulation which is essential to engine performance
and life. Be certain to remove all grass, dirt, and
combustible debris from muffler area.
