CARBURETOR ADJUSTMENT
WARNING: The chain will be mov- ing during most of this procedure. Wear your protective equipment and observe all safety precautions. The chain must not move at idle speed.
The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions:
SChain moves at idle. See IDLE
adjusting procedure.
SSaw will not idle. See IDLE
Idle Speed-T
Allow engine to idle. If the chain moves, idle is too fast. If the engine stalls, idle is too slow. Ad- just speed until engine runs without chain movement (idle too fast) or stalling (idle too slow). The idle speed screw is located in the area above the primer bulb and is labeled T.
STurn idle screw (T) clockwise to increase engine speed.
S Turn idle screw (T) counterclockwise to decrease engine speed.
If you require further assistance or are unsure about performing this procedure, contact your authorized service dealer or call our customer assistance help line at
COOLING SYSTEM
To keep the working temperature as low as possible the machine is equipped with a cooling system.
The cooling system consists of:
SAir intake on the starter S Air guide plate
S Fins on the flywheel
S Cooling fins on the cylinder
S Cylinder cover (directs cold air over the cylinder)
Clean the cooling system with a brush after each use, more often in demanding condi- tions. A dirty or blocked cooling system re- sults in the machine overheating which causes damage to the piston and cylinder.
