• If waste gets stuck and causes blockage around the

intake air cooling vent or between the cylinder fins, it
may cause the engine to overheat, and that in turn
may cause mechanical failure on the part of the
brushcutter. (MA6)

■ PROCEDURES TO BE PERFORMED AFTER

1. Remove the muffler, insert a screwdriver into the

vent, and wipe away any carbon buildup. Wipe away
any carbon buildup on the muffler exhaust vent at
the same time. (MA7)

2. Tighten all screws, bolts, and fittings.
3. Check to see if any oil or grease has worked its way

in between the clutch lining and drum, and if it has
wipe it away using oil-free, lead-free gasoline.

• Aged fuel is one of major causes of engine starting

failure. 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.

• When disposing your machine, fuel or oil for the

machine, be sure to allow your local regulations.
