• 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.
5. File at an angle perpendicular to the bar, and at an angle of 25° to the

every 5 sharpenings. If the depth gauges are also trimmed it is
essential that the original profile be restored.

depth gauge. Depth gauge measuring jigs are available from most
