Tensioning the saw chain

WARNING! A slack chain may jump off
!
and cause serious or even fatal injury.
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up
the slack.
Check the chain tension every time you refuel. NOTE! A
new chain has a running-in period during which you
should check the tension more frequently.
Tension the chain as tightly as possible, but not so tight
that you cannot pull it round freely by hand.
• Loosen the bar nut that holds the clutch cover and
chain brake. Use the combination spanner.
• 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 nut
while holding up the tip of the bar. Check that you can
pull the saw chain round freely by hand, and that there
is no slack on the underside of the bar.
The position of the chain tensioning screw on our
chainsaws varies from model to model. See instructions
under the heading What is what? to find out where it is on
your model.

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 chainsaw manufacturer we have developed an
optimal chain oil which, with its vegetable oil base, is also
biodegradable. 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.
