cleaned thoroughly, in particular the
teeth of the rail. Use a whisk and a dry
cloth for that.
• Oil the individual chain links with the
aid of an oil suction gun with pinpoint
tip (available in the specialist trade).
Place individual oil drops onto the ar-
ticulated links and onto the tooth tips of
the individual chain links.

Sharpening the saw chain

An incorrectly sharpened saw
chain increases the danger of
spring-back!
Use cut-protection gloves when
you are handling the chain or the
chain bar.
A sharp chain guarantees an optimal
cutting performance. It eats effort-
lessly through the wood and leaves
large, long wooden chips. 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 cut-
ting tooth and a depth limiting projection.
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 sharpen-
ing the chain, which guarantee that the
cutting edges are sharpened at the cor-
rect angle and to the correct depth. For
the inexperienced user of chainsaws,
we recommend to have the saw chain
sharpened by a specialist 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.
