MAINTENANCE

Y

WARNING: Mufflers fitted with catalytic converters get very hot during use and remain so for some time after stopping. This also ap- plies at idle speed. Contact can re- sult in burns to the skin. Remember the risk of fire!

WARNING: Bear in mind that: Engine exhaust fumes contain car- bon monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or any- where that is poorly ventilated. The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near flam- mable material!

WARNING: The inside of the muffler contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler.

Cooling system

The engine is equipped with a cooling system for maintaining the right operating temperature.

The cooling system consists of the follow- ing components:

1.Air intake on the starter device (Z).

2.Fan blades on the flywheel (AA).

3.Cooling fins on the cylinder (BB).

4.Cylinder cowling (guides cooling air flow

against cylinder surfaces).

Clean the cooling system by brushing once a week, or more often, if necessary.

A dirty or blocked cooling system will cause the blower to overheat and this will damage the cylinder and piston.

Air filter

The air filter (CC) must be regularly cleaned to remove dust and dirt in order to avoid:

SCarburetor malfunctions S Starting problems

S Loss of engine power

S Unnecessary wear to engine parts S Excessive fuel consumption

S Elevated content of harmful exhaust fumes.

CCDD

Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty.

Cleaning the air filter

Remove the air filter cover (DD) and take out the filter. Wash it clean in warm, soapy water. Rinse thoroughly. Ensure that the filter is dry before reinstalling it.

An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals.

CAUTION! A damaged air filter must always be replaced.
