N
Place selected file gauge (1) on the
saw chain
N
Check height of the depth gauge
If the depth gauge protrudes above the
file gauge, it must be reworked.
N
Set sharpening angle on guide
piece to 0°
N
Advance saw chain until a depth
gauge is under the file
N
Replace round file with the
triangular file (2) (special
accessory)
N
Set stop (3) so that the file does not
touch the cutting edge
N
Set depth adjusting screw (4) so
that the depth gauge is filed down to
the necessary height (flush with the
gauge)
N
Remove the file gauge and file all
depth gauges with this setting
N
Afterwards, dress the leading edge
of the depth gauge parallel to the
service mark (see arrow) – when
doing this, be careful not to further
lower the highest point of the depth
gauge
N
Lay the file gauge on the saw chain
– the highest point of the depth
gauge must be flush with the file
gauge
WARNING
Depth gauges that are too low increase
the kickback tendency of the chain saw.
Saw chains with humped drive link
The upper part of the humped drive link
(with service mark) is lowered at the
same time as the depth gauge of the
cutter.
