MAINTENANCE

Spark plug

The condition of the spark plug

Cooling system

To maintain as low an operating temperature as possible the power cutter is equipped with a cooling system.

is affected by:

•An incorrect carburettor setting.

•An incorrect fuel mixture (too much oil).

•A dirty air filter.

These factors cause deposits on the spark plug electrode that may result in malfunction or starting difficulties.

•If the machine is low on power, difficult to start or runs poorly while idling always check the spark plug first. If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm. The spark plug should be changed after about one month of operation or earlier if necessary.

The cooling system consists of:

1.An air intake on the starter unit.

2.Air flow guide.

3.Cooling fins on the flywheel.

4.Cooling fins on the cylinder

5.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.

NOTE! Always use the recommended type of spark plug. (see chapter ”Technical data”)! An incorrect spark plug can damage the cylinder/piston.

Silencer

The silencer 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 or inflammable material. Some silencers are fitted with a special spark arrest screen.

If your power cutter is fitted with this type of silencer then the screen should be cleaned at least once a week. This is done using a wire brush.

NOTE! If the screen is damaged in anyway it should be replaced. If the screen is blocked this will result in the engine overheating and damage to the cylinder and piston. Never use a power cutter with a defective silencer.
