Figure 29

Every 10 to 15 hours of operation: Remove and clean the spark plug. Adjust the spark plug electrode gap to 0.024 inch (0.6 mm). If the spark plug must be replaced, use only an champion CJ8 or equivalent type spark plug of the correct heat range. See Figure 29.

CAUTION!

Before removing the spark plug, clean the area around the plug to prevent dirt and debris from getting into the engine’s internal parts.

50-Hour Maintenance

Every 50 hours of operation (more frequently in dusty or dirty conditions):

nRemove and clean the cylinder cover and clean grass and dirt from the cylinder fins.

nRemove the cutting attachment, cutting attachment holder and gear shaft collar. Remove the filler plug from the side of the gearcase and press new grease into the gearcase until old grease is pushed out. Use only lithium-base grease such as Shindaiwa Gear Case Lubricant or equivalent. See Figure 30.

nLubricate main shaft splines.

nUse a hooked wire to extract the fuel filter from inside the fuel tank.

See Figure 31.

CAUTION!

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

nRemove and replace the filter ele- ment. 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.
