Files and le guiding
- Use a special round le (optional accessory) for saw chains sharpening. Normal
round les are not suitable.
- Use the round le of diameter 4.0 mm.
- The le should only engage the cutter part on the forward stroke. Lift the le off
the cutter part on the return stroke.
- Sharpen the shortest cutter rst. Then the length of this shortest cutter becomes
the standard for all other cutters on the saw chain.
- Guide the le as shown in the gure.
- A le holder (optional accessory) makes le guidance easier. The le holder has
markings for the correct sharpening angle of 30°. When using the le holder, align
the markings parallel to the saw chain, and limit the ling depth to 4/5 of the le
diameter.
- After sharpening the chain, check the depth of the cut using the chain gauge tool
(optional accessory).
- Remove the small excess with a special at le (optional accessory).
- Round off the front of the depth gauge.
