GENERAL SAFETY PRECAUTIONS
English – 15
• Loosen the bar nuts that hold the clutch cover/chain
brake. Use the combination spanner. Then tighten the
bar nuts by hand as tight as you can.
• Raise the tip of the bar and stretch the chain by
tightening the chain tensioning scre
w 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
sa
ws 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
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 v
egetable 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.
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 r
uns out before the saw chain oil.
However, this safety feature requires that you use the
right sort of chain oil (if the oil is too thin it will run out
before the fuel), and that you adjust the carburetor as
recommended (a lean mixture may mean that the fuel
lasts longer than the oil) and that you also use the
recommended cutting equipment (a bar that is too
long will use more chain oil).
Checking chain lubrication
• Check the chain lubrication each time you refuel. See
instructions under the heading Lubricating the bar tip
sprocket.
Aim the tip of the bar at a light coloured surface about
20 cm (8 inches) a
way. After 1 minute running at 3/4
throttle you should see a distinct line of oil on the light
surface.
If the chain lubrication is not working:
• Check that the oil channel in the bar is not obstructed.
Clean if necessar
y.
• Check that the groove in the edge of the bar is clean.
Clean if necessar
y.
!
WARNING! Poor lubrication of cutting
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
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.
