5. MAINTENANCE
5.1.
AIR FILTER CLEANING
Under normal operating conditions, the air filter must
be cleaned daily. However, more frequent cleaning is
recommended in extremely dirty conditions.
To clean the air filter: Remove the locking nut at the bottom
of the filter box cover. Remove the foam filter. Brush with a
large brush. Wash with mineral spirits until clean. Squeeze to
get all the remaining liquid out. Reinstall.
5.2.
COOLING THE MOTOR
This motor is air-cooled.
Keep the air inlet screen on the motor free of dirt. Make sure it
is protected from obstruction by grass, leaves, branches, etc.
5.3.
SPARK PLUG
Monitor and clean the spark plug regularly (every 15 hours of
operation). A dirty, carbonized or misadjusted spark plug will
make it difficult to start and harm motor performance.

IMPORTANT
Dirt entering the motor through the carburetor is one of
the biggest causes of motor wear; therefore, it is very
important to regularly check the air filter.
