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.
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.
sharpening the cutting teeth:
G
- Sharp edge angle (30°)
- Breast angle (85°)
- Sharpness depth (0.65 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!
Sharpening a saw chain requires some
practice. In addition, special tools are
required to sharpen the saw chain that
ensure that the chain is sharpened at the
correct angle and depth. Proceed fol-
