■Remove and clean the cylinder cover and clean dirt and debris from the cylinder cooling fins.

■Remove the sprocket cover and inspect the sprocket for excessive dirt, debris, or wear. Remove the guide bar and clean out the guide bar groove. If the sprocket is excessively worn, replace it with a new one. See Figure 32.

■Lubricate the gearcase. To perform this operation, first remove the gearcase from the upper outer tube as follows (Figure 33):

CAUTION!

Do not remove the D-shaped shim washer from the gearcase clamp! The shim washer prevents damage from overtightening the tube clamp screw.

•loosen the gearcase clamp bolt.

•remove the index bolt from the gearcase.

•slide the gearcase out of the tube.

Using a lever-type grease gun, pump lithium-base grease (about 10 grams) into the grease fitting until you see old grease being purged

from the gearcase, this can be seen in the outer tube cavity at the input end of the gearcase. Clean up excess grease, then reassemble the gearcase onto the outer tube.

■Use a hooked wire to extract the fuel filter from inside the fuel tank (Figure 34). Inspect the fuel filter element for signs of contamination. Replace it with a new one if re- quired. Before reinstalling the filter, inspect the fuel line. If you find damage or deterioration, remove the unit from service until it can be inspected by a Shindaiwa- trained service technician.

CAUTION!

Make sure you do not pierce the fuel line with the end of the hooked wire. The line is delicate and can be damaged easily.
