The angle must also be maintained for all knives. If the
angle is uneven, the chain will run irregularly, wear out
quickly, and break prematurely.
As these requirements can only be met with sufficient and
regular practice:
• Use a file holder
A file holder must be used when sharpening the saw-
chain by hand. The correct file angles are marked on
it.
• Hold the file horizontally (at the correct angle to the
guide bar) and file according to the angle mark on the
file holder. Support the file holder on the top plate and
the depth gauge.
• Always file the blade from the inside out.
• The file sharpens only in the forward movement. Lift it off when moving
backward.
• Do not touch the fastening straps and dynamic links with the file.
• Continue to rotate the file regularly to prevent uneven wear.
• Use a piece of hardwood to remove bones from cut edges.
All knives must be of the same length. Otherwise, they will be of different heights. This
makes the chain run irregularly and increases the risk of breaking.
