CHECK CHAIN TENSION

WARNING: Wear protective gloves when handling chain. The chain is sharp and can cut you even when it is not moving.

Chain tension is very important. Chain stretches during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use your saw.

DUnplug unit from the power source.

D Use a screwdriver to move chain around guide bar to ensure kinks do not exist. The chain should rotate freely.

DLoosen bar clamp nuts until they are fin- ger tight against the bar clamp.

DTurn the adjusting screw clockwise until the chain solidly contacts bottom of guide bar rail. Then, turn adjusting screw an additional 1/4 turn.

CHECK CHAIN SHARPNESS

A sharp chain makes wood chips. A dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARPENING in the SERVICE AND ADJUSTMENTS section.

CHECK GUIDE BAR

Conditions which require guide bar main- tenance:

SSaw cuts to one side or at an angle. S Saw has to be forced through the cut. S Inadequate supply of oil to the bar and

chain.

Check the condition of the guide bar each time the chain is sharpened. A worn guide bar will damage the chain and make cut- ting difficult.

After each use, with unit disconnected from power source, clean all sawdust from the guide bar and sprocket hole.

To maintain guide bar:

S Disconnect the chain saw from the pow- er source.

S Loosen and remove bar clamp nuts. Remove bar and chain from saw.

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

D Continue turning the adjusting screw until the tension is correct.

DTighten bar clamp nuts with a wrench. D Recheck chain tension.
