GENERAL SAFETY PRECAUTIONS

•Loosen the bar nut that holds the clutch cover and chain brake. Use the combination spanner. Then retighten the bar nut as tightly as you can by hand.

•Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner. Tighten the chain until it does not sag from the underside of the bar.

•Use the combination spanner to tighten the bar nuts while lifting the tip of the bar at the same time. Check that you can pull the chain round freely by hand and that it does not sag from the underside of the bar.

The position of the chain tensioning screw on our chain saws varies from model to model. See instructions under the heading What is what? to ﬁnd out where it is on your model.
