setting the chain tension. Turn the bar cover knob
counterclockwise to loosen the bar cover but do not
remove the bar cover. Turn the chain tensioning screw
clockwise to tension chain. Turn the guide bar knob
clockwise to tighten. Refer to the Replacing the bar
and chain section for additional information.

no slack on the underside of the guide bar, the chain is
snug, but it can be turned by hand without binding.

out of the bar groove.
Note: New chain tends to stretch; check chain tension
frequently.
