•
Keep your hands, feet, face, clothing, and other
body parts away from the muffler and other hot
surfaces. Allow engine components to cool before
performing maintenance.
•
Do not change the engine governor speed or
overspeed the engine.

Service Interval: Every 100 hours or yearly,
whichever comes first—Clean the
primary air filter (more often in dirty
or dusty conditions).
Every 400 hours or yearly, whichever comes
first—Replace the primary air filter (more often
in dirty or dusty conditions).
Every 600 hours/Yearly (whichever comes
first)—Replace the safety air filter (more often in
dirty or dusty conditions).
Note:
Service the air cleaner more frequently if
operating conditions are extremely dusty or sandy.

air-cleaner body
Note:
Avoid knocking the filter into the side of
the body.

Inspecting the Filters
1. Inspect the safety filter. If it is dirty, replace both
the safety and primary filters.
Important:
Do not attempt to clean the
safety filter. If the safety filter is dirty, then
the primary filter is damaged.
2. Inspect the primary filter for damage by looking
into the filter while shining a bright light on the
outside of the filter. If the primary filter is dirty,
bent, or damaged, replace it.
Note:
Holes in the filter appear as bright spots.
Do not clean the primary filter.
