2. Adjust the idle speed with the idle adjustment screw.
The idle adjustment screw T is identified with a "T"
mark.
3. Turn the idle adjustment screw clockwise until the
cutting attachment starts to turn.
4. Turn the idle adjustment screw counterclockwise
until the cutting attachment stops.
The idle speed is correct when the engine operates
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. Do not
use the product until it is correctly adjusted
or repaired.
Note: Refer to Technical data on page 18 for the
recommended idle speed.
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 Technical data on page
18
.
Note: Clean the spark arrester screen weekly on
mufflers without a catalytic converter and on mufflers
with a catalytic converter this must be done monthly.
1. Stop the engine and let the muffler become cool.
2. Remove the muffler cover.
3. Replace the spark arrester screen if it is damaged.
4. Remove the screw and remove the spark arrester
screen.
5. Clean the spark arrester screen with a wire brush.
Remove dirt from the inlet and outlet of the muffler
with the wire brush.
6. 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.
To do maintenance on the trimmer
head
1. Only use the recommended cutting attachment and
cutting attachment guard. See,
