Maintenance (continued)
10/15-hour Maintenance
Remove and clean or replace 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 CMR5H or equivalent
resistor type spark plug of the cor-
rect heat range.
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.
NOTE:
The NGK CMR5H also meets the require-
ments for electro magnetic compliance
(EMC).
Remove and replace the fuel filter
element.
■
Use a hooked wire to extract the fuel
filter from inside the fuel tank. Inspect
the fuel filter element. If it shows signs
of contamination from debris, replace it
with a genuine Shindaiwa replacement
fuel filter element.
Before reinstalling the filter, inspect
the fuel line. If you discover damage
or deterioration, the unit should be
removed from service unitl it can be
inspected by a Shindaiwa-trained ser-
vice technician..
135 hour maintenance
■
Combustion chamber should be decar-
bonized, and the valve clearance should
be adjusted. It is highly recommended
that this is done by a Shindaiwa-trained
service technician.
