HEAT RANGE

• Check spark plug heat range by observing electrode color. If

the electrode of the spark plug is wet appearing or dark color,

replace the spark plug with hotter type one. If it is white or

glazed appearing, replace the spark plug with colder type

one.

Inspect every 6 000 km (4 000 miles, 12 months).

driver or a bar to avoid its damage.

prevent short/open circuit.
