MAINTENANCE

Muffler

NOTE!

Some mufflers are fitted with a catalytic converter. See “Technical data” to see whether you clearing saw is fitted with a catalytic converter.

The muffler is designed to dampen the noise level and to direct the exhaust fumes away from the user. The exhaust fumes are hot and can contain sparks, which can result in fire if the exhaust fumes are directed towards a dry and inflammable mate- rial. Some mufflers are equipped with a special spark arrest screen. If your machine is fitted with this type of screen it should be cleaned regularly. This is done using a wire brush. On mufflers without a catalytic converter the screen should be cleaned weekly, or replaced if necessary. On mufflers fitted with a catalytic converter the screen should be checked and cleaned monthly. If the screen is damaged it should be replaced. If the screen is frequently blocked, this can be a sign that the function of the catalytic converter is impaired. Contact your dealer to inspect the muffler. A blocked screen will cause the engine to overheat resulting in damage to the cylinder and piston. Also see under “Maintenance”.

NOTE!

Never use a machine with a defective muffler.

Cooling system

To maintain as low operating temperature as possible the engine is equipped with a cooling system.

The cooling system consists of:

1.An air intake on the starter unit.

2.Cooling fins on the flywheel.

3.Cooling fins on the cylinder

4.Cylinder cover (leads cold air onto the cylinder).

Clean the cooling system using a brush at least once a week, in difficult conditions more often.

A dirty or blocked cooling system leads to the engine overheating resulting in damage to the cylinder and piston.
