resharpened several times, have it sharpened in our
authorized service center.
Sharpening criteria:
WARNING:
An excessive distance between
the cutting edge and depth gauge increases the
risk of kickback.
►

between cutting edge and depth gauge 3.
Minimum cutter length (3 mm)
—
All cutter length must be equal. Different cutter
lengths prevent the saw chain from running
smoothly and may cause the saw chain to break.
—
Do not sharpen the chain when the cutter length
has reached 3 mm or shorter. The chain must be
replaced with new one.
—
The chip thickness is determined by the distance
between the depth gauge (round nose) and the
cutting edge.
—
The best cutting results are obtained with following
distance between cutting edge and depth gauge.

— The sharpening angle of 30° must be the same on
all cutters. Different cutter angles cause the chain
to run roughly and unevenly, accelerate wear, and
lead to chain breaks.
