15.Lift the tip of the guide bar up to check for sag.

16.Release the tip of the guide bar and turn the chain tensioning screw 1/2 turn clockwise. Repeat this process until sag does not exist.

17.Hold the tip of the guide bar up and tighten the bar mounting nuts securely.

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. Ensure that the chain brake is not set.

Note: If chain is too tight, it will not rotate. Loosen the bar nuts slightly and turn the tension adjuster 1/4 turn counter- clockwise. Lift the tip of the guide bar up and retighten the bar mounting nuts securely. Ensure that the chain will rotate without binding.
