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.
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.
Cleaning the air filter
Remove the air filter cover and take out the filter. Blow
clean with compressed air.
