Oiling the saw chain
Clean and oil the chain regularly.
In this way, you keep the chain
sharp and get optimum machine
performance. In case of damage
due to inadequate maintenance of
the saw chain, the guarantee claim
is invalid. Remove the batteries
and use cut-resistant gloves when
working with the chain or with the
blade.
• 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 dan-
ger 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 cut-
ting 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°)
- Apex angle (60°)
- Sharpness depth (0.65 mm)
- Round file diameter (4.0 mm)
Deviations from the meas-
urement data of the cutting
geometry can lead to an
increase of the spring-back
slope of the machine. In-
creased danger of accident!
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
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. Remove the saw chain (refer
to the section on operating
the saw). The chain should be
well-tensioned to ensure proper
sharpening.
2. For the sharpening, a round file
with 4.0 mm diameter is neces
-
sary.
