•

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.

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.
