■
Remove and clean the cylinder cover
and clean dirt and debris from the cylin-
der cooling fins.
Remove and replace the fuel filter
element.
Use a hooked wire to extract the fuel filter

50 hour maintenance
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 0.6 - 0.7 mm
(0.024 - 0.028 inch). If the spark plug must
be replaced, use only the an NGK BPMR6A
or equivalent resistor type spark plug of the
correct 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.
10/15 hour maintenance
Maintenance (continued)
NOTE
The NGK BPMR6A also meets the
requirements for electro magnetic compli-
ance (EMC).
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.
