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 SPEED--T

adjusting procedure.

SSaw will not idle. See IDLE SPEED--T ad- justing procedure.

Idle Speed-T

Allow engine to idle. If the chain moves, idle is too fast. If the engine stalls, idle is too slow. Adjust 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 speed screw (T) clockwise to in- crease engine speed.

STurn idle speed screw (T) counterclock- wise to decrease engine speed.

If you require further assistance or are unsure about performing this procedure, contact your authorized service dealer or call 1--800--554--6723.

BAR MAINTENANCE

If your saw cuts to one side, has to be forced through the cut, or been run with an improper amount of bar lubrication it may be neces- sary to service your bar. A worn bar will dam- age your chain and make cutting difficult.

After each use, ensure ON/STOP switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole.

To maintain guide bar:

SMove ON/STOP switch to the STOP posi- tion.

SLoosen and remove chain brake nuts and chain brake. Remove bar and chain from saw.

Oil Holes

S Burring of guide bar rails is a normal process of rail wear. Remove these burrs with a flat file.

SWhen rail top is uneven, use a flat file to re- store square edges and sides.
