CHAIN ADJUSTMENT
See CHAIN TENSION in ASSEMBLY sec- tion.
CHAIN SHARPENING
Chain sharpening is a complicated task and requires special tools. We recommend that you refer chain sharpening to a professional chain sharpener.
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
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

FUEL SYSTEM
Under FUELING ENGINE in the OPERA- TION section of this manual, see message labeled IMPORTANT regarding the use of gasohol in your chain saw.
Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum depos- its during storage. Add stabilizer to the gaso- line in the fuel tank or fuel storage container. Follow the mix instructions found on stabiliz- er containers. Run engine at least 5 minutes after adding stabilizer.
