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.
1.Unplug unit from the power source.
2.Use a screwdriver to move chain around guide bar to ensure kinks do not exist. The chain should rotate freely.
NOTE: It is recommended that the saw be turned upside down for chain tensioning.
3.Loosen bar mounting nuts until they are finger tight.
4.Turn the adjusting screw clockwise until the chain solidly contacts bot- tom of guide bar rail. Then, turn ad- justing screw an additional 1/4 turn. This is correct chain tension setting.
Adjusting Screw -- 1/4 Turn
NOTE: To tighten the chain, turn the adjusting screw clockwise; to loosen the chain, turn the adjusting screw counter- clockwise.

5.Check the tension by lifting the chain from the guide bar. Remove some of the stiffness in the chain by pulling down on the chain several times.
6.Continue turning the adjusting screw until the tension is correct (see step 4).
7.Tighten bar mounting nuts with a wrench.
8.Recheck chain tension.
WARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in serious in- jury.
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 maintenance:
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 cutting 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 power source.
S Loosen and remove bar mounting nuts. Remove bar, bar clamp plate and chain from saw.
S Clean the oil holes and bar groove af- ter each 5 hours of operation.

Guide Bar Groove
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 restore square edges and sides.
