GENERAL SAFETY PRECAUTIONS
Sharpening cutting teeth
To sharpen cutting teeth you will need a round ﬁle and a ﬁle
Check that the chain is correctly tensioned. A slack chain
will move sideways, making it more difﬁcult to sharpen
Always ﬁle cutting teeth from the inside face outwards.
Reduce the pressure on the return stroke. File all the teeth
on one side of the bar ﬁrst. Then turn the saw over and ﬁle
the remaining teeth from 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 setting raker clearance
When you sharpen the cutting teeth you reduce the raker
clearance (=cutting depth). To maintain optimal cutting
performance you must ﬁle back the raker lip to the
On a low-kickback cutting link the front edge of the raker
lip is rounded. It is very important that you maintain this
radius or bevel when you adjust the raker clearance.
We recommend that you use our raker gauge to achieve
the correct clearance and bevel on the raker lip.
WARNING! The risk of kickback is increased
if the raker clearance is too large!
Setting the raker clearance
Before setting the raker clearance the cutting teeth should
be newly sharpened.
We recommend that you adjust the raker clearance every
third time you sharpen the chain. NOTE! This
recommendation assumes that the length of the cutting
teeth is not reduced excessively.
To adjust the raker clearance you will need a ﬂat ﬁle and a
Place the gauge over the raker lip.
Place the ﬁle over the part of the lip that protrudes through
the gauge and ﬁle off the excess. The clearance is correct
when you no longer feel any resistance as you draw the
ﬁle over the 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.
