Maintaining and Sharpening the Saw Chain
Sawing effortlessly with a properly sharpened saw chain
A properly sharpened saw chain cuts through wood effortlessly even with very little pushing.
Never use a dull or damaged saw chain
–this leads to increased physical strain, increased vibration load, unsatisfactory cutting results and increased wear.
NClean the saw chain
NCheck the saw chain for cracks and damaged rivets
NReplace damaged or worn chain components and adapt these parts to the remaining parts in terms of shape and level of wear – rework accordingly
Compliance with the angles and dimensions listed below is absolutely necessary. An improperly sharpened saw chain – especially depth gauges that are too low – can lead to increased kickback tendency of the chain saw – risk of injury!
Chain pitch

689BA027 KN
The chain pitch marking (a) is embossed in the area of the depth gauge of each cutter.
Marking (a) | Chain pitch | |
| Inches | mm |
7 | 1/4 P | 6.35 |
1 or 1/4 | 1/4 | 6.35 |
6, P or PM | 3/8 P | 9.32 |
2 or 325 | 0.325 | 8.25 |
3 or 3/8 | 3/8 | 9.32 |
4 or 404 | 0.404 | 10.26 |
The diameter of file to be used depends on the chain pitch – see table "Sharpening tools".
The angles of the cutter must be maintained during resharpening.
