• REPLACEMENT PLUG IS A NGK CMR7H.
IMPORTANT
• Note that using any spark plug other than those des-
ignated may result in the engine failing to operate prop-
erly or in the engine becoming overheated and dam-
aged.
• To install the spark plug, first turn the plug until it is
finger tight, then tighten it a quarter turn more with a
socket wrench.
INTAKE AIR COOLING VENT
WARNING
• Check the intake air cooling vent after every 25
hours of use for blockage, and remove any waste
which has attached itself to the brushcutter.
IMPORTANT
• If waste gets stuck and causes blockage around the
intake air cooling vent, it may cause the engine to over-
heat, and that in turn may cause mechanical failure
on the part of the brushcutter.
■ PERIODICAL SERVICE POINTS
1. CYLINDER FINS
Periodically check and clean the cylinder fins in the re-
pair specialty store.
MUFFLER
WARNING
• Inspect periodically, the muffler for loose fasten-
ers, any damage or corrosion. If any sign of ex-
haust leakage is found, stop using the machine
and have it repaired immediately in the repair spe-
cialty store.
• Note that failing to do so may result in the engine
catching on fire.
ANGLE TRANSMISSION
• The reduction gears are lubricated by multipurpose,
lithium-based grease in the angle transmission.
Supply new grease every 25 hours of use or more
often depending on the job condition.
• Remove the bolt of the grease nipple and the bolt
opposite side of the grease nipple. Install new grease
into the grease nipple to arrange for old grease to
exit from the opposite side.
10. Storage
Aged fuel is one of major causes of engine starting fail-
ure. Before storing the unit, empty the fuel tank and run
the engine until it uses all the fuel left in the fuel line and
the carburetor. Store the unit indoor taking necessary
measures for rust prevention.
