Maintenance

_ INTAKE AIR COOLING VENT

• Never touch the cylinder, muffler,

or spark plugs with your bare

hands immediately after stopping

the engine. The engine can

become very hot when in

operation, and doing so could

result in severe burns.

• When checking the machine to

make sure that it is okay before

using it, check the area around

the muffler and remove any

debris. Failing to do so could

cause the muffler to become

overheated, and that this in turn

could cause the engine to catch

on fire. Always make sure that the

muffler is clean and free of

debris.

• Check the intake air cooling vent

and the area around the cylinder

cooling fins after every 25 hours of

use for blockage, and remove any

waste which has attached itself.

Note that it is necessary to remove

the engine cover shown in (MA10)

in order to be able to view the upper

part of the cylinder.

• 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. (MA10)

_ (MA11) PROCEDURES TO BE

PERFORMED AFTER EVERY 100

HOURS OF USE

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 and cylinder

exhaust port at the same time.

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.
