Saw chain sharpening
NOTE: Never saw with a blunt chain. The saw chain is
blunt if you have to push the product into the tree and
the chips are very small.
1. Have the saw chain (14) sharpened professionally at an authorised
service centre or sharpen the chain yourself by using a proper
sharpening kit. Also observe the sharpening instructions supplied
with the sharpening kit.
WARNING! Only sharpen the saw chain yourself if you
are trained and have experience! Use proper tools to
sharpen the saw chain!
2. The height difference between the tooth and the ridge is the cutting
depth. When sharpening the saw chain (14) you have to consider
the following points (Fig. 41).
- File angle
- Cutting angle
- File position
- Diameter of round file
- File depth
Fig. 41
3. To sharpen the chain proceed as follows:
− Use protective gloves.
− Ensure the chain is correctly tensioned.
− Engage the chain brake to lock the chain on the bar.
4. Use a chain file, whose diameter is 1.1 times the cutting tooth
depth. Make sure 20 % of the file diameter is above the cutter’s top
plate.
NOTE: A file guide is available from most reputable
tool merchants and is the easiest way to hold the file at
the correct position.
5. File at an angle perpendicular to the bar, and at an angle of 25° to
the direction of travel (Fig. 42).

6. File each tooth from the inside towards outside only. File one side
of the chain first than turn the saw around and repeat the process.
7. Sharpen each tooth equally by using the same number of strokes.
8. Keep all cutter lengths equal. Check the safety depth gauge height
every 5 sharpenings. If the depth gauges are also trimmed it is
essential that the original profile be restored.
