WARNING:
An excessive distance increases the risk of kick-

back.
−
The sharpening angle of 30 ° must be the same on
all cutters. Differences in angle cause the chain to
run roughly and unevenly, accelerate wear, and
lead to chain breaks.
−
The side plate angle of the cutter is determined by
the depth of penetration of the round file. If the
specified file is used properly, the correct side
plate angle is produced automatically.
−
Side plate angle for each saw chain are as follows:
Chain blade 90PX: 75 °

File and file guiding
−
Use a special round file (optional accessory) for
saw chains to sharpen the chain. Normal round
files are not suitable.
−
Diameter of the round file for each saw chain is as
follows:
Chain blade 90PX: 4.5 mm (3/16")
−
The file should only engage the cutter on the
forward stroke. Lift the file off the cutter on the
return stroke.
−
Sharpen the shortest cutter first. Then the length
of this shortest cutter becomes the standard for all
other cutters on the saw chain.

Guide the file as shown in the figure.
−
The file can be guided more easily if a file holder
(optional accessory) is employed. The file holder
has markings for the correct sharpening angle of
30 ° (align the markings parallel to the saw chain)
and limits the depth of penetration (to 4/5 of the
file diameter).

After sharpening the chain, check the height of the
depth gauge using the chain gauge tool (optional
accessory).

Remove any projecting material, however small,
with a special flat file (optional accessory).
−
Round off the front of the depth gauge again.
