The cutters are poor in sharpness.
To adjust the cutter clearance
1. Loosen the cutter fi xing nuts.
2. Fully tighten the cutter fi xing bolts and then loosen them approx.
1/2 turn.
3.
With the bolts set at that position, tighten the cutter fi xing nuts.

worn or damaged. Also be sure to replace damaged cutter blade.

NOTE
Lubrication should be applied at 50 hour intervals and more
frequently with heavy use.

NOTE
If the fi lter is hard due to dust and dirt, replace it.
Cleaning the cylinder fi ns (Fig. 20)
When leaves get caught between cylinder fi ns (16), the engine may
overheat, resulting in lower output. To
avoid this, always keep cylinder
fi ns and fan case 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.

any excess carbon from the exhaust port or muffl er inlet every 100
hours of operation.
