50-Hour Maintenance

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 plug must be replaced, use only a Champion CJ8 or equivalent spark plug of the correct heat range. For electromagnetic compliance (EMC), use NGK BMR6A.

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

Every 50 hours of operation

(more frequently in dusty or dirty condi- tions):

Remove and clean the cylinder cover and clean grass and dirt from the cylin- der fins.

Remove the cutting attachment, holder and the gear shaft collar. Remove the filler plug from the side of the gearcase and press new grease into the gearcase until the old grease has been pushed out. Use only lithium-base grease such as Shindaiwa Gearcase Lubricant or equivalent. See Figure 37.

Use a hooked wire to extract the fuel filter from inside the fuel tank. Remove and replace the filter element. Before reinstalling the filter, inspect the condition of the fuel line. If damage or deterioration are noted, the unit should

be removed from service until it can be inspected by a Shindaiwa-trained service technician. See Figure 38.

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.
