MAINTENANCE
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water.
Bevel gear
The bevel gear is filled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is filled
The grease in the bevel gear does not normally need to be changed except if repairs are carried out.
Drive shaft
The drive shaft must be greased every three months during
Spark plug
The spark plug condition is influenced by:
•Incorrect carburetor 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 0.020 inch (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.
Winter use
Running problems can occur when using the machine in the cold and snowy conditions caused by:
•Too low engine temperature.
•Icing of the air filter and carburetor. Special measures are therefore often required:
•Partly mask the air inlet on the starter to increase the working temperature of the engine.
•Preheat the intake air to the carburettor by utilising the heat from the muffler.
Temperature 5°C (41°F) or colder
•Fit the cooling air duct with the arrow pointing to the snow flake.
