11 ROUTINE MAINTENANCE
11.1 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 filter every 25 hours, or more regularly if conditions are exceptionally dusty.
11.1.1 Cleaning the air filter (Fig. 20)
Remove the air filter cover (16) and take out the filter. Wash it clean in warm, soapy water.
Ensure that the filter is dry before refitting it.
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.
11.2 Fuel filter
When the engine runs short of fuel supply, check the fuel cap and the fuel filter for blockage.
11.3 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 0,6-0,7 mm.
The spark plug should be replaced after about a month in operation or earlier if necessary.
Recommended Spark plug type:
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.
