9.5.2
Fuel filter (Fig. 25)
When the engine runs short of fuel supply, check the fuel cap and the fuel filter for blockage.
9.5.3
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 three-quarters full with grease.
The grease in the bevel gear does not normally need to be changed except if repairs are
carried out.
9.5.4
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: POWACG2013
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.
10 MAINTENANCE TIMESCALE
The following intervals apply to normal operating conditions
only. If your daily working time is longer or operating
