Basic adjustments and run-in
The basic carburetor adjustments are done at the
factory. The basic adjustments are high speed needle
(H) = 2 ½ turns and low speed needle (L) = 2 turns.
To give the components of the engine sufficient
lubrication during run-in, adjust the idle speed. Adjust
the idle speed to 600-700 rpm below the recommended
maximum idle speed.
CAUTION: If the saw chain rotates at idle
speed, turn the idle speed screw
counterclockwise until the saw chain stops.
To adjust the low speed needle (L)
1. Turn the low speed needle clockwise and
counterclockwise to find the highest idle speed.
2. Turn the low speed needle (L) ¼ turn
counterclockwise from the position of the highest idle
speed.
L
+ 1/4
To adjust the idle speed screw (T)
1. Start the product.
2. Turn the idle speed screw clockwise until the saw
chain starts to rotate.
3. Turn the idle speed screw counterclockwise until the
saw chain stops.
Note: The idle speed is correctly adjusted when the
engine runs correctly in all positions. The idle speed
must also be safely below the speed at which the saw
chain starts to rotate.
WARNING: If the saw chain does not stop
when you turn the idle speed screw, speak
to your servicing dealer. Do not use the
product until it is correctly adjusted.
To adjust the high speed needle (H)
CAUTION: To make sure that the
adjustment is correct, speak to your
servicing dealer who has access to a
tachometer. Do not override the
recommended maximum idle speed.
1. Start the product.
2. Operate the product at full throttle for approximately
10 seconds.
3. Turn the high speed needle (H) ¼ counterclockwise.
4. Operate the product at full throttle for approximately
10 seconds again and listen to the difference in the
idle speed.
5. Turn the high speed needle (H) ¼ counterclockwise.
6. Operate the product at full throttle for approximately
10 seconds again and listen to the difference in the
idle speed.
Note: You have operated the product at adjustments
of H=±0, H=+¼, H=+½ from the basic adjustments.
The engine has a different sound for each
adjustment.
7. Turn the high speed needle (H) clockwise until the
adjustments is correct and the product has the
correct sound.
H
Note: The high speed needle (H) is correctly
adjusted when the product 4-cycles a little at full
throttle. If the product "screams" the product is set
too lean, which can cause damage to the engine.
The product is set too rich if the product 4-cycles and
ejects smoke.
To examine if the carburetor is correctly
adjusted
• Make sure that the product has the correct
acceleration capacity.
• Make sure that the product 4-cycles a little at full
throttle.
• Make sure that the saw chain does not rotate at idle
speed.
• If the product is not easy to start or has less
acceleration capacity, adjust the low and high speed
needles.
CAUTION: Incorrect adjustments can
cause damage to the engine.
To replace a broken or worn starter
rope
1. Loosen the screws to the starter housing.
