8. Maintenance
1. Cleaning the air filter
Remove the air filter cover 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.
If the machine is used in dusty conditions the air filter should be
soaked in oil. See instructions under the heading Oiling the air
filter.
2. Oiling the air filter
Always use special filter oil. Filter oil contains a solvent to
make it spread evenly through the filter. You should
therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour
off the excess before fitting the filter to the machine. Never
use common engine oil. This would drain through the filter
quite quickly and collect in the bottom.
■ 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.
