this causes damage to the cylinder and
piston.
To adjust the idle speed screw (T)
The basic carburetor adjustments are done at the
factory. You can adjust the idle speed but for more
adjustments, refer to your servicing dealer.
To give the components of the engine sufficient
lubrication during run-in, adjust the idle speed. Adjust
the idle speed to the recommended idle speed. Refer to
Technical data on page 27 .
CAUTION: If the saw chain rotates at idle
speed, turn the idle speed screw
counterclockwise until the saw chain stops.
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 examine if the carburetor is correctly
adjusted
•
Make sure that the product has the correct
acceleration capacity.
•
Make sure that the saw chain does not rotate at idle
speed.
CAUTION: Incorrect adjustments can
cause damage to the engine.

drive disc spring (B) and the pulley (C).
WARNING: You must be careful when
you replace the return spring or the
starter rope. The recoil spring is in
tension when it is wound up in the starter
housing. If you are not careful, it can
eject and cause injuries. Use protective
glasses and protective gloves.
6. Remove the used starter rope from the handle and
the pulley.
7. Attach a new starter rope to the pulley. Wind the
starter rope approximately 3 turns around the pulley.
8. Connect the pulley to the recoil spring (D). The end
of the recoil spring must engage in the pulley.
9. Assemble the drive disc spring, the drive disc and
the center screw.
10. Pull the starter rope through the hole in the starter
housing and the starter rope handle.
11. Make a tight knot at the end of the starter rope. (Fig.
104)
To tighten the recoil spring
1. Put the starter rope into the notch in the pulley.
2. Turn the starter pulley approximately 2 turns
clockwise.
3. Pull the starter rope handle and pull out the starter
rope fully.
4. Put your thumb on the pulley.
5. Move your thumb and release the starter rope.
6. Make sure that you can turn the pulley ½ turn after
the starter rope is fully extended. (Fig. 105)
To assemble the starter housing on the
product
1. Pull out the starter rope and put the starter in
position against the crankcase.
2. Slowly release the starter rope until the pulley
engages with the pawls.
3. Tighten the screws that hold the starter. (Fig. 106)
To clean the air filter
Clean the air filter from dirt and dust regularly. This
prevents carburetor malfunctions, starting problems,
loss of engine power, wear to engine parts and more
fuel consumption than usual.
1. Remove the air filter cover and the air filter.
2. Use a brush or shake the air filter clean. Use
detergent and water to clean it fully.
Note: An air filter that is used for a long time can not
be fully cleaned. Replace the air filter regularly and
always replace a defective air filter.
