• 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
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.
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.
However, this safety feature requires that you use the
r
ight 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.
!
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.
