10/15-Hour Maintenance
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
CMR6H or equivalent resistor type spark
plug of the correct heat range.
See Figure 26.
NOTE:
The NGK CMR6H also meets the
requirements for electromagnetic
compliance (EMC).
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 condi-
tions):
■ Remove and clean the cylinder cover
and clean grass and dirt from the
cylinder fins.
■ 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 27.
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.
135-hour or Annual Maintenance.
■ The valve clearance should be ad-
justed annually or every 135 hours. It
is highly recommended that this is
done by a Shindaiwa-trained service
technician.
