CARBURETTOR ADJUSTMENT
a WARNING: The chain will be moving
during most of this procedure. Wear your
protective equipment and observe all safety
precautions. The chain must not move at idle
speed.
Indications for idle speed adjustment
The carburetor has been carefully set at the factory.
Adjustments may be necessary if you notice any of the
following conditions:
The chain moves at idle. See IDLE SPEED-T
ADJUSTMENT procedure.
The saw will not idle. See IDLE SPEED-T
ADJUSTMENT procedure.
Idle speed-T adjustment
Allow the engine to idle. If the chain moves, the idle is
too fast. If the engine stalls, the idle is too slow.
Adjust the speed until the engine runs without chain

Clean the cooling system with a brush after each use,
more often in demanding conditions. A dirty or blocked
cooling system results in the machine overheating
which causes damage to the piston and cylinder.
