■ GEAR CASE

• Remove cutter, cutter holder A and plug and  insert

fresh lubricant. (MA4)

■ FUEL STRAINER
Drain the fuel from the tank. Remove the fuel strainer
from the fuel tank and clean the fuel strainer. (MA5)

A clogged fuel filter may cause poor acceleration of the
engine.

■ SPARK PLUG

Take out the spark plug, check the electrodes, and if
contaminated, clean them with a wire brush, etc. every
25 hours of use.
When mounting the spark plug, screw the plug in with
your fingers, and then tighten it with the plug wrench
supplied as a standard accessory.
The spark gap should be adjusted to 0.6 to 0.7 mm.
(MA6)

If you use the plug wrench to start tightening the spark
plug, the thread might become damaged.

■ INTAKE AIR COOLING VENT

• Check the intake air cooling vent and the area around

the cylinder cooling fins, and remove any waste which
has attached itself to the brushcutter. (MA7)

• Note that failing to do so could cause the muffler to

become overheated, and that this in turn could cause
the brushcutter to catch on fire.
