NOTE
Lubrication should be applied 3g at 20 hour
intervals and more frequently with heavy use.
Fuel fi lter (Fig. 15)
Remove the fuel fi lter from the fuel tank and thoroughly
wash it in solvent. After that, push the fi lter into the
tank completely.
NOTE
If the fi lter is hard due to dust and dirt, replace it.
Cleaning the cylinder fi ns (Fig. 16)
When leaves get caught between cylinder fi ns (7),
the engine may overheat, resulting in lower output.
To avoid this, always keep cylinder fi ns and cylinder
cover clean.
Every 100 operating hours, or once a year (more
often if conditions require), clean fi ns and external
surfaces of engine of dust, dirt and oil deposits which
can contribute to improper cooling.
Cleaning the muffl er (Fig. 17)
Remove the muffl er and spark arrestor (if so
equipped), and clean out any excess carbon from
the exhaust port or muffl er inlet every 100 hours of
operation.
