Sharpening the saw chain
Sharpen the saw chain when:
•
Mealy sawdust is produced when damp wood is cut;
• Thechainpenetratesthewoodwithdifculty,even
when heavy pressure is applied;
• The cutting edge is obviously damaged;
• The saw pulls to the left or right in the wood.
(caused by uneven sharpening of the saw chain or
damage to one side only)
Sharpen the saw chain frequently but a little each time. Two
orthreestrokeswithaleareusuallysufcientforroutine
resharpening. When the saw chain has been resharpened sev-
eral times, have it sharpened in our authorized service center.

— 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.
