der fins.

n

Remove the cutting attachment, cutting

attachment holder and gear shaft collar.

Remove the filler plug from the side of

the gear case and press new grease into

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.

Every 10 to 15 hours
of operation:

Remove and clean the spark plug. Adjust

the spark plug electrode gap to 0.024 - 0.028

inch (0.6 - 0.7 mm). If the spark plug must

be replaced, use only an NGK BPMR6A or

equivalent resistor type spark plug of the

correct heat range. See Figure 27.

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.

10/15-Hour Maintenance

Remove and replace the filter element.

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 deteriora-

tion is noted, the unit should be removed

from service until it can be inspected or

repaired by a Shindaiwa-trained service

technician.
