Sharpening The Saw Chain - Makita EY2650H Originalbetriebsanleitung

Sharpening the saw chain

Sharpen the saw chain when:
- Mealy sawdust is produced when damp wood is cut;
-
applied;
- The cutting edge is obviously damaged;
- The saw pulls to the left or right in the wood. The reason for this behavior is
uneven sharpening of the saw chain, or damage to one side only.
Sharpen the saw chain frequently, but remove only a little material each
When the saw chain has been resharpened several times, have it sharpened in
MAKITA authorized service center.
Sharpening criteria:
- All cutter length (A) must be equal. Cutters of different length prevent the
chain from running smoothly, and may cause the chain to break.
- The chip thickness is determined by the distance between the depth gauge
(round nose) and the cutting edge (B).
- The best cutting results are obtained with following distance between cutting
edge and depth gauge.
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

- Proper angle for each saw chain are as follows:
