on guide bar. Turning screw counter clockwise will loosen saw 

chain on guide bar.

3.   Tighten guide bar nuts firmly.  Move saw chain backwards on guide 

bar by hand.  Saw chain should move freely on guide bar if it is 

in proper mesh with sprocket.  If saw chain is difficult to rotate or 

binds on guide bar, it is too tight. 

                        

Keep the saw chain lubricated and properly adjusted and the guide bar 

nuts tightened firmly at all times.
