Shindaiwa AHS2510/EVC manual Remove and replace the fuel filter element

Maintenance (continued)

50-hour maintenance

Every 50 hours of operation; more fre- quently in dusty conditions:Remove and clean the cylinder cover and clean dirt and debris from the cylinder cooling fins.

Remove and replace the fuel filter element.

ŶUse a hooked wire to extract the fuel filter from inside the fuel tank. Inspect the fuel filter element. If it shows signs of contam- ination, replace with a genuine Shindaiwa replacement fuel filter element.

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.

Before reinstalling the new filter element, inspect the condition of all the fuel system components (fuel pick-up line, fuel return line, tank vent line, tank vent, fuel cap and fuel tank). If damage, splitting or deterioration is noted, the unit should be removed from service until it can be inspected or repaired by a Shindaiwa-trained service technician.

Gearcase lubrication

To perform this operation, first remove the gearcase from the outer tube as follows:

1.Loosen the gearcase clamp bolt.

2.Remove the index bolt from the gearcase.

CAUTION!

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

3.Slide the gearcase out of the tube. Using a grease gun, pump lithium- base grease (about 10 grams) into the grease fitting (B) on the gearcase until you see old grease being purged from the gearcase. Purged grease will be visible in the outer tube cavity.

4.Clean up excess grease, then reas- semble the gearcase onto the outer tube. Make sure the index bolt fits into the hole on the outer tube. Securely tighten both bolts.
