MAINTENANCE

Maintenance

WARNING! Make sure the cutting

!attachment has stopped before cleaning, carrying out repairs or an inspection. Disconnect the HT lead from the spark plug.

Air filter

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

•Carburettor malfunctions

•Starting problems

•Loss of engine power

•Unnecessary wear to engine parts.

•Excessive fuel consumption.

Clean the air filter daily, or more often in demanding conditions.

The air filter is dismantled once the air filter cover has been lifted off. Press in the catches on the top of the air filter cover and lower the cover.

Remove the air filter and check that it is undamaged. Replace with a new air filter if you believe it to be defective.

Clean the filter by knocking the filter carefully against a hard surface and blowing with compressed air from inside. Never brush the dirt away. Replace the air filter if it is very dirty.

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. A damaged air filter must always be replaced.

When reassembling, make sure that the filter completely seals against the filter holder.

Spark plug

WARNING! The muffler gets very hot in use

!and remains so for a short time afterwards. Do not touch the muffler if it is hot!

If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.7-0.8 mm. The spark plug should be replaced after about a month in operation or earlier if necessary.

CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder.

Muffler

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.

Regularly check that the muffler is securely attached to the machine.

Never use a machine that has a faulty muffler.
