To adjust the idle speed
Your Husqvarna product is made to specifications that
decrease harmful emissions.
1. Make sure that the air filter is clean and the air filter
cover is attached before you adjust the idle speed.
2. Adjust the idle speed with the idle speed screw T
which is identified with "T" mark.
a) Turn the idle speed screw T clockwise until the
cutting attachment starts to rotate.
b) Turn the idle speed screw T counterclockwise
until the cutting attachment stops.
WARNING: If the cutting attachment
does not stop when you adjust the idle
speed, speak to your servicing dealer.
Do not use the product until it is correctly
adjusted or repaired.
3. 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 rotate.
Note:
Refer to
Technical data on page 28
for the
recommended idle speed.
To adjust the start throttle speed
(545FR, 545RX, 545RXT)
1. Apply idle speed to the product.
2. Push the start throttle lock. Refer to
Product
overview on page 2
.
3. If the start throttle speed is less than 4000 rpm, turn
the adjuster screw (A) clockwise. When the cutting
attachment starts to rotate, turn the adjuster
screw (A) 1/2 turn clockwise.

5 mm
4. If the start throttle speed is more than 6500 rpm, turn
the adjuster screw (A) counterclockwise. When the
cutting attachment starts to rotate, turn the adjuster
screw (A) 1/2 turn.
To clean the muffler
WARNING: The muffler gets very hot during
and after operation, also at idle speed. Risk
of fire and burn injuries.
1. If the muffler on your product has a spark arrester
screen, clean it weekly with a steel brush. Replace
the spark arrester screen if it is damaged.
CAUTION:
A blocked spark arrester screen
causes the engine to become too hot and
results in damage to the cylinder and piston.
CAUTION: If the spark arrester screen is
frequently blocked, let your service agent
examine the muffler.
To clean the cooling system and starter
pawls
The cooling system includes:
• The air intake on the starter (A)
• The fins on the flywheel (B)
• The cooling fins on the cylinder (C)
• The cylinder cover (D)
