GENERAL SAFETY PRECAUTIONS

•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.

•Release the knob by folding it out.

•Turn the knob anti clockwise to loosen the bar cover.

•Adjust the tension on the chain by turning the wheel down (+) for tighter tension and up (-) to loosen the tension.

•Tighten the bar clutch by turning the knob clockwise.

•Fold the knob back in to lock the tensioning.

Lubricating cutting equipment

WARNING! Poor lubrication of cutting

! equipment may cause the chain to snap, which could lead to serious, even fatal injuries.

Chain oil

Chain oil must demonstrate good adhesion to the chain and also maintain its ﬂow characteristics regardless of whether it is warm summer or cold winter weather.

As a chain saw manufacturer we have developed an optimal chain oil which has a vegetable oil base. We recommend the use of our own oil for both maximum chain life and to minimise environmental damage. If our own chain oil is not available, standard chain oil is recommended.
