General information about how to sharpen
the cutting teeth
Do not use a blunt saw chain. If the saw chain
is blunt, you must apply more pressure to
push the guide bar through the wood. If the
saw chain is very blunt, there will be no wood
chips but sawdust.
A sharp saw chain eats through the wood and
the wood chips becomes long and thick.
The cutting tooth (A) and the depth gauge
(B) together makes the cutting part of the
saw chain, the cutter. The difference in height
between the two gives the cutting depth
(depth gauge setting).
A
When you sharpen a cutting tooth, think about
the following:
• Filing angle.
• Cutting angle.
• File position.
• Round file diameter.

It is not easy to sharpen a saw chain
correctly without the correct equipment. Use
the recommended file gauge. This will help
you to keep maximum cutting performance
and the kickback risk at a minimum.
WARNING:
increases a lot if you do not follow
the sharpening instructions.

chain.
To sharpen the cutting teeth
1. Use a round file and a file gauge to
sharpen the cutting teeth.
Note:
Saw chain filing and file
Refer to
gauge on page 18 for information about
which file and gauge that we recommend
for your saw chain.
2. Make sure that the saw chain has the
correct tension. A saw chain without the
correct tension moves from side to side.
This does not make it easy to sharpen the
saw chain. Refer to
on page 15 for instructions.
3. Move the file from the inner side of
the cutting teeth and out. Decrease the
pressure on the pull stroke.
4. Remove filing material on all teeth on one
side first.
