NOTE

Properly lubricate the cutter sliding surfaces with machine oil.

Gear case (Fig. 14)

Apply a good quality lithium based grease through the grease fi tting

until a small amount comes out between the cutter blades and the

gear case.

NOTE

Lubrication should be applied 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 (8), 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.

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.
