Sharpening cutting teeth
To sharpen cutting teeth you will need a round file and a
file gauge. See instructions under the heading Technical
data for information on the size of file and gauge that are
recommended for the chain fitted to your chain saw.
• Check that the chain is correctly tensioned. A slack
chain will move sideways, making it more difficult to
sharpen correctly.
• 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 chain saw over 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 4 mm (0.16") the
chain is worn out and should be replaced. (8)
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.
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.

GENERAL SAFETY PRECAUTIONS
Tensioning the chain
WARNING! A slack chain may jump off
!
and cause serious or even fatal injury.
WARNING! Always wear approved
!
protective gloves. Even a non-moving
chain can cause serious cuts to
yourself or persons you bump into with
an exposed chain.
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. (9)
• Undo 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. (10)
• 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. (11)
• 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.

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, 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.
