2. Adjust the idle speed with the idle adjustment screw.
The idle adjustment screw T is identified with a "T"
mark.

smoothly in all positions. The idle speed must be below
the speed when the cutting attachment starts to turn.
WARNING: If the cutting attachment
does not stop when you adjust the idle
speed, turn to your nearest servicing dealer.

recommended idle speed.
To do maintenance on the muffler
The muffler decreases the noise level and points 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 that holds the spark arrestor
screen.
4. Clean the spark arrestor screen if it is blocked or
replace it if it is damaged.
CAUTION:
The spark arrestor screen
must be replaced if it is damaged. Do not
use a product if the spark arrestor screen on
the muffler is missing or defective.
CAUTION: If the spark arrestor screen
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 screen 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 components that follow:
1. Air intake on the starter.
2. Fins on the flywheel.
