Remove all slack from the chain by turning the chain
tensioner clockwise until the chain seats snugly against the
bar with the drive links in the bar groove. (Fig
12

Fully
tighten the two bar mounting nuts.
The chain is correctly tensioned when there is no sag on the
underside of the guide bar, the chain is snug, but it can be
turned by hand without binding.

tensioner 1/4 turn counterclockwise. Lift the tip of the guide bar
up and retighten the knob. Ensure that the chain will rotate
without binding.
