•
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 op-
timal cutting performance. It eats
effortlessly 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
projection. The vertical separation dis-
tance between these two determines
the sharpness depth.
•
The following values must be noted in
sharpening the cutting teeth:
84
- Sharp edge angle (30°)
H
- 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
accident!
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
I
from the mains.
2. Remove the saw chain (refer
to the section on operating
the saw). The chain should be
well-tensioned to ensure proper
sharpening.
3. For the sharpening, a round file
with 4.0 mm diameter is neces-
sary.
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 withdrawing it.
