Correctly sharpened chain
A properly sharpened chain slices 
through wood effortlessly and requires 
very little feed pressure.
Do not work with a dull or damaged 
chain as it will increase the physical 
effort required, cause high vibrations, 
produce unsatisfactory cutting results 
and a higher rate of wear.
: Clean the chain.
:
Check the chain
 for cracks in the 
links and damaged rivets.
: Replace any damaged or worn parts 
of the chain and match the new 
parts to the shape and size of the 
original parts.
It is absolutely essential to comply 
with the angles and dimensions 
specified below. If the saw chain is 
incorrectly sharpened – and in 
particular if the depth gauge is set 
too low – there is a risk of increased 
kickback of the chainsaw, with 
resulting risk of injury.
The chain pitch (e.g. 
3
/
8
") is marked on 
the depth gauge end of each cutter.
Use only special saw chain 
sharpening files. Other files have the 
wrong shape and cut.
Select file diameter according to chain 
pitch – see table “Sharpening Tools”.
You must observe certain angles when 
resharpening the chain cutter.
A = Filing angle
B = Side plate angle
Cutter shapes:
Micro = Semi-chisel
Super = Full chisel
The specified angles A and B are 
obtained automatically if the 
recommended files or sharpening tools 
and correct settings are used.
