• Always file cutting teeth from the inside face. Reduce
the pressure on the return stroke. File all the teeth on
one side first, then turn the chainsaw and file the teeth
on the other side.
• File all the teeth to the same length. When the length
of the cutting teeth is reduced to 5/32 inch (4 mm) the
chain is worn out and should be replaced. (23)
General advice on adjusting depth gauge setting
• When you sharpen the cutting tooth (A) the depth
gauge setting (C) will decrease. To maintain optimal
cutting performance the depth gauge (B) has to be
filed down to achieve the recommended depth gauge
setting. See instructions under the heading Technical
data to find the correct depth gauge setting for your
particular chain. (24)
WARNING! The risk of kickback is
!
increased if the depth gauge setting is
too large!
Adjustment of depth gauge setting
• The cutting teeth should be newly sharpened before
adjusting the depth gauge setting. We recommend
that you adjust the depth gauge setting every third
time you sharpen the cutting teeth. NOTE! This
recommendation assumes that the length of the
cutting teeth is not reduced excessively.
• You will need a flat file and a depth gauge tool. We
recommend that you use our depth gauge tool to
acheive the correct depth gauge setting and bevel for
the depth gauge.
• Place the depth gauge tool over the chain. Detailed
information regarding the use of the depth gauge tool,
will be found on the package for the depth gauge tool.
Use the flat file to file off the tip of the depth gauge that
protrudes through the depth gauge tool. The depth
gauge setting is correct when you no longer feel
resistance as you draw the file along the depth gauge
tool. (25)
Tensioning the saw chain
WARNING! A slack chain may jump off
!
the bar 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.

GENERAL SAFETY PRECAUTIONS
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. (26)
• Release the knob by folding it out. (30)
• Turn the knob anti clockwise to loosen the bar cover.
(31)
• Adjust the tension on the chain by turning the wheel
down (+) for tighter tension and up (-) to loosen the
tension. (32)
• Tighten the bar clutch by turning the knob clockwise.
(33)
• Fold the knob back in to lock the tensioning. (34)
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 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 chainsaws 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
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).
