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 0,026 inch
(0,65 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.
1 Foam plastic filter (urethan filter)
2 Felt filter
3 Screen
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
Cleaning the air filter
Close the choke control by setting the choke into a choke
position.
• Remove the air filter cover and take out the filter. Wash
it clean in warm, soapy water. Clean also the inside of
the filter cover by using air or a brush. Ensure that the
filter is dry before refitting it.
• Remove the Felt filter from the filter holder and gently
brush debris from the filter.
• Install screen and Felt filter to the air filter holder.
• Install the foam filter in the air filter cover.
• Install the air filter cover.
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.
Damaged, very dirty, or fuel-
soaked air filter must always be replaced.
Air intake screen
Check that the air intake is not blocked, for example, by
leaves or rubbish. A clogged air intake reduces the
machine’s blowing capacity and increases the engine’s
working temperature, which can result in engine failure.
Stop the engine and remove the object.
Fuel filter
Check the fuel filter for contamination and the fuel hose
for cracks or other defects. Replace if necessary.
