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.
Clean the outside of the spark plug. Remove it and check
the electrode gap. Adjust the gap to 0,6-0,7 mm, or
replace the spark plug. Check that the spark plug is fitted
with a suppressor.

Contact can result in burns to the skin.

• Refit the air filter and air filter cover. Do not forget to
put the air screen back in place. If the grill is missing,

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.

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.

excess oil out of the filter inside the plastic bag and pour
off the excess before fitting the filter to the machine. Never
