Sharpening the saw chain
Sharpen the saw chain when:
(caused by uneven sharpening of the saw chain or
damage to one side only)
Sharpen the saw chain frequently but a little each time.
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.

— 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 cut-

and unevenly, accelerate wear, and lead to chain breaks.
