3. Adjust the idle speed with the idle adjustment screw
T which is identified with "T" mark. Turn the idle
adjustment screw clockwise until the saw chain
starts to turn.
4. Turn the idle adjustment screw counterclockwise
until the saw chain stops.
The idle speed is correct when the engine operates
smoothly in all positions. The idle speed must be below
the speed when the saw chain starts to turn.
WARNING: If the saw chain does not
stop when you adjust the idle speed, turn
to your nearest servicing dealer. Do not use
the product until it is correctly adjusted or
repaired.
Note: Refer to
Technical data on page 23
for the
recommended idle speed.
To do maintenance on the muffler
The muffler decreases the noise level and directs the
exhaust gases away from the operator.
WARNING:
Mufflers that have catalytic
converters get very hot during operation and
will stay hot for some time after you stop the
product. This also applies at idle speed. If
you touch the product it can result in burns
to the skin. Think about of the risk of fire.
1. Stop the product and let it cool down.
2. Remove the cover to the muffler.
3. Remove the screw holding the spark arrestor mesh.
4. Clean the spark arrestor mesh if it is blocked or
replace it if it is damaged.
CAUTION: The spark arrestor mesh
must be replaced if it is damaged. Do not
use a product if the spark arrestor mesh on
the muffler is missing or damaged.
CAUTION: If the spark arrestor mesh
is frequently blocked it can be a sign that
performance of the catalytic converter is
decreased. Turn to your servicing dealer
to examine the muffler. A blocked spark
arrestor mesh will cause overheating and
result in damage to the cylinder and piston.
Cooling system
The product has a cooling system to keep the operation
temperature as low as possible.
Clean the components of the cooling system with a
brush weekly or more frequently in rougher conditions.
A dirty or blocked cooling system makes the product too
hot which causes damage to the piston and cylinder.
The cooling system has the following components:
1. Air intake on the starter.
2. Fins on the flywheel.
3. Cooling fins on the cylinder.
4. Cylinder cover.
5. Muffler cover.
6. Muffler plate.
