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 central screw from the cover, incline it
towards you and pull out. Once the cover is removed, remove
the foam filter. Brush with a large brush. Wash with mineral
spirits until clean. Squeeze to get all the remaining liquid out
and re-install.
6.1. AIR FILTER CLEANING
6.2. COOLING THE MOTOR
6.3. SPARK PLUG
This screen prevents grass, leaves, etc. from entering the
cooling system flaps. As this motor is cooled by air, this screen
must always be clean to allow fresh water into the fan.
Monitor and clean the spark plugs regularly (every 10 hours of
operation). A dirty, carbonized or misadjusted spark plug will
make it difficult to start and harm motor performance.
To check the distance from the electrode, remove the spark
plug and check with a gauge that the distance is 0.9 mm.
Re-install and check that it works.
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.
