Oiling
the
saw chain
Clean and oil the chain regularly. In
this way, you keep the chain sharp
and get optimum machine perfor-
mance. In case of damage due to
inadequate maintenance of the saw
chain, the guarantee claim is invalid.
Remove the power plug and use
cut-protection gloves when you are
handling the chain or the chain bar.
•
Oil the chain after cleaning, after 10
hours of use or at least once weekly,
depending on which comes first.
•
Before oiling, the chain bar must be
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
cutting tooth and a depth limiting projec-
tion. 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.
