A saw chain is blunt if you have
to press the cutting equipment
through the wood and the wooden
chips are very small. In the case
of a very blunt saw chain, no chip
cuttings result at all, only sawdust.
• The sawing parts of the chain are the
cutting elements, which consist of a
cutting tooth and a depth limiting pro-
jection. The vertical separation distance
between these two determines the
sharpness depth.
• The following values must be noted in
sharpening the cutting teeth:
- Sharp edge angle (30°)
- Breast angle (85°)
- Sharpness depth (0.65 mm)
- Round file diameter (4.0 mm)
Deviations from the measure-
ment data of the cutting geom-
etry can lead to an increase of
the spring-back slope of the
machine. Increased danger of ac-
cident!
Special tools are necessary for sharpening
the chain, which guarantee that the cutting
edges are sharpened at the correct angle
and to the correct depth. For the inexperi-
enced user of chainsaws, we recommend
to have the saw chain sharpened by a spe-
cialist or a specialist workshop. If you think
yourself capable of sharpening the chain,
you can acquire the special tools in the
specialist trade.
1. Switch the saw off and unplug it from
the mains.
2. Remove the saw chain (refer to the
section on operating the saw). The
chain should be well-tensioned to en-
sure proper sharpening.
3. For the sharpening, a round file with
4.0 mm diameter is necessary.
Other diameters damage the
chain and can lead to danger
during work!
4. Sharpen only from the inside to the
outside. Guide the file from the inner
side of the cutting teeth to the outer
side. Lift the file when you are with-
drawing it.
5. Sharpen first the teeth on one side.
Turn the saw around and sharpen the
teeth of the other side.
6. The chain is worn and must be re-
placed by a new saw chain if only
approx. 4 mm of the cutting teeth is
remaining.
7. After the sharpening, all cutting ele-
ments must now be equal in length
and width.
8. After every third sharpening, the
sharpness depth (depth limitation)
must be checked and the height filed
with the aid of a flat file. The depth lim-
itation should be set back about 0.65
mm from the cutting tooth. After the
setting back of depth limitation, round
it off a little at the front.
