• 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.
GENERAL SAFETY PRECAUTIONS
• 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.
Never use waste oil! Using waste oil can be dangerous
to you and damage the machine and environment.
IMPORTANT! When using vegetable based saw chain
oil, dismantle and clean the groove in the bar and saw
chain before long-term storage. Otherwise there is a risk
of the saw chain oil oxidizing, which will result in the saw
chain becoming stiff and the bar tip sprocket jamming.
Filling with chain oil
• All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also
adjustable.
• The saw chain oil tank and the fuel tank are designed
so that the fuel runs out before the saw chain oil.
