To do maintenance of the muffler
WARNING:
Do not use a product
with a damaged muffler.
WARNING:
The mufflers become
very hot during and after operation, also
at idle speed. Use protective gloves to
prevent burn injuries.
1. Stop the engine and let the muffler become cool.
2. Replace the spark arrester screen (C) if it is
damaged.
3. Remove the screws (E) and remove the exhaust
duct (D).

Note:
The inner surfaces of the muffler contain
chemicals that can cause cancer. Be careful
not to touch these elements if the muffler is
damaged.
4. Remove the spark arrester screen (C) and clean
it with a wire brush. Remove dirt from the inlet
and outlet of the muffler with the wire brush.
Also, remove dirt from the exhaust port of the
cylinder with the wire brush.
5. Attach the spark arrester screen (C) and the
exhaust duct (D) with the screws (E). Tighten the
screws to 2-3 Nm.
6. Make sure that the muffler is correctly attached
to the product. Tighten the screws (A) and (B) to
8–12 Nm.

To examine the air intake screen
A clogged air intake screen decreases the blow force
and increases the temperature of the engine. An
increased temperature can result in engine failure.
1. Stop the engine.
2. Examine the air intake screen for damages and
make sure that it is attached correctly.
3. Remove dirt, leaves and unwanted materials
from the air intake screen.
To clean the air filter
Clean the air filter regularly from dirt and dust. This
prevents carburetor malfunctions, starting problems,
loss of engine power, wear to engine parts and more
fuel consumption than usual. Clean the air filter at an
interval of 40 hours of operation or less if it is heavy
operation conditions.
