Adjusting Screw

5.Check the tension by lifting the chain from the guide bar. Remove some of the stiffness in the chain by pulling down and letting go of the chain sever- al times.

6.Continue turning the adjusting screw until the tension is correct (see step 4).

7.Tighten bar clamp 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 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.

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

Worn Groove

Correct Groove

Replace the guide bar when the groove is worn, the guide bar is bent or crack--ed, or when excess heating or burring of the rails occurs. If replacement 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.

LUBRICATION

Bar Oil Fill Cap

SCheck bar and chain oil before use and every 15 minutes while operating the saw. See GUIDE BAR AND CHAIN OIL un- der the OPERATION section.
