NOTE: The adjusting pin may need to be slightly
repositioned with the chain tensioning screw
so that it is aligned with the position of the bar
chain tensioning pin hole.
 Replace and fingertighten the bar mounting
nuts. The bar must be free to move for tension
adjustment.
 Remove all slack from the chain by turning the
chain tensioning screw clockwise until the chain
seats snugly against the bar with the drive links
in the bar groove.
 Lift the tip of the guide bar up to check for sag.
