Maintenance (continued)
10/15 hour maintenance
Ever y 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
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 BPMR6A also meets the
requirements for electro magnetic com-
pliance (EMC).
