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.
5. Sharpen first the teeth on one side.
Turn the saw around and sharpen
the teeth of the other side.
6. The chain is worn and must be
replaced by a new saw chain if
only approx. 4 mm of the cutting
teeth is remaining.
7. After the sharpening, all cutting
elements must now be equal in
length and width.
8. After every third sharpening, the
sharpness depth (depth limitation)
must be checked and the height filed
with the aid of a flat file. The depth
limitation should be set back about
0.65 mm from the cutting tooth.
After the setting back of depth limita-
tion, round it off a little at the front.
Adjusting the chain tension
The adjustment of the chain tension is de-
scribed in the chapter: Assembly,

Starting up a new saw chain
In the case of a new chain, the tensioning
force decreases after some
