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 le, whose diameter is 1.1 times the cutting tooth depth. Make
sure 20 % of the le diameter is above the cutter’s top plate.
NOTE:
A le guide is available from most reputable tool merchants
and is the easiest way to hold the le 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. 43).
