MAINTENANCE

Bevel gear

The bevel gear is filled with the right amount of grease at the factory. However, before using the machine you should check that the bevel gear is filled 3/4 full with grease. Use JONSERED special grease.

The grease in the bevel gear does not normally need to be changed except if repairs are carried out.

Spark plug

The spark plug condition is influenced by:

•Incorrect carburettor adjustment.

•An incorrect fuel mixture (too much or incorrect type of oil).

•A dirty air filter.

These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties.

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 0.5 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.

Check that the spark plug is fitted with a suppressor.
