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).

STurn idle speed screw (T) clockwise to in-

crease engine speed.

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

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.

SClean the oil holes and bar groove after each 5 hours of operation.

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.

Worn Groove

Correct Groove

Replace guide bar when the groove is worn, the guide bar is bent or cracked, or when exce-

ssheating or burring of the rails occurs. If re- placement is necessary, use only the guide bar specified for your saw in the repair parts list or on the decal located on the chain saw.

CHAIN SHARPENING

Chain sharpening is a complicated task that requires special tools. We recommended you refer chain sharpening to a professional chain sharpener.

IGNITION TIMING

Ignition timing is fixed and nonadjustable.

SPARK PLUG

The spark plug should be replaced each year to ensure the engine starts easier and runs better.

1.Loosen 3 screws on cylinder cover.

2.Remove the cylinder cover.

3.Pull off the spark plug boot.

4.Remove spark plug from cylinder and discard.

5.Replace with Champion RCJ--7Y spark plug and tighten securely with a 19 mm socket wrench. Spark plug gap should be 0,5 mm.

6.Reinstall the spark plug boot.

7.Reinstall the cylinder cover and 3 screws. Tighten securely.
