MAINTENANCE

Correctly adjusted carburettor

When the carburettor is correctly adjusted the machine accelerates without hesitation and burbles a little at maximum speed. It is also important that the blades do not move when the engine is idling or when the choke control is in the start position. If the low speed jet L is set too lean it may cause starting difﬁculties and poor acceleration.

If the high speed jet H is set too lean it will result in less power, less performance, poor acceleration and/or damage to the engine. If both the L and H jets are set too rich it will results in acceleration problems or too low a working speed.

Mufﬂer

CAUTION! Some mufﬂers are ﬁtted with a catalytic converter. See chapter on Technical data to see whether your machine is ﬁtted with a catalytic converter.

The mufﬂer is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause ﬁre if directed against dry and combustible material.

Some mufﬂers are equipped with a special spark arrestor mesh. If your machine has this type of mufﬂer, you should clean the mesh at least once a week. This is best done with a wire brush.

On mufﬂers without a catalytic converter the mesh should be cleaned weekly, or replaced if necessary. On mufﬂers ﬁtted with a catalytic converter the mesh should be checked, and if necessary cleaned, monthly. If the mesh is damaged it should be replaced. If the mesh is frequently blocked, this can be a sign that the

performance of the catalytic converter is impaired. Contact your dealer to inspect the mufﬂer. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston. See also instructions under the heading Maintenance.

CAUTION! Never use a machine with a defective mufﬂer.

WARNING! Mufﬂers ﬁtted with catalytic

! converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin.

Remember the risk of ﬁre!

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.

The cooling system consists of:

1Air intake on the starter.

2Fins on the ﬂywheel.

3Cooling ﬁns on the cylinder.

4Cylinder cover (directs cold air over the cylinder).

Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.
