• If the spark plug is dirty, clean it and make sure that
the electrode gap is correct, refer to
on page 24
.
• Replace the spark plug if it is necessary.
To do maintenance on the muffler
WARNING: The muffler decreases the noise
level and points the exhaust gases away
from the operator. The exhaust gases are
hot and can contain sparks. This can cause
fire if pointed against dry and flammable
material.
WARNING: Mufflers with catalytic converters
become hot during operation. Risk of burn or
fire. This also applies at idle speed. To
examine if your product has a catalytic
converter, refer to [xref].
1. Stop the engine and let the muffler become cool.
2. Remove the muffler cover.
3. Remove the screw and remove the spark arrester
screen.
4. Examine the spark arrester screen for damage.
Replace a damaged spark arrester screen.
5. Clean the spark arrester screen with a wire brush.
6. Remove dirt from the inlet and outlet of the muffler
with the wire brush.
7. Attach the spark arrester screen with the screw.
CAUTION: If the spark arrester screen is
frequently blocked, it can be a sign that
performance of the catalytic converter is
decreased. Speak to your servicing dealer to
examine the muffler. A blocked spark
arrester screen causes overheating and
results in damage to the cylinder and piston.
Air filter
Remove dust and dirt from the air filter to keep it clean in
order to prevent:
• Carburettor malfunctions.
• Starting problems.
• Loss of engine power.
• Unnecessary wear to engine parts.
• Too much fuel consumption.
Clean the air filter at an interval of 25 hours, or more
regularly if conditions are unusually dusty.
To clean the air filter
CAUTION: Always replace an air filter that is
damaged, very dirty or soaked with fuel.
If you use an air filter for a long time, it cannot be fully
cleaned. Replace the air filter with a new one at regular
intervals.
