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
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.
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

increased if the depth gauge setting is

GENERAL SAFETY PRECAUTIONS
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
Tensioning the 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
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.
