How to properly sharpen cutting teeth?

In instances when the chain is blunt you need to exert more pressure to force the bar through the wood and the chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings. A sharp chain easily goes through the wood and leaves thick, long, chips. Whenever sharpening the tooth you need to pay special attention to following: file position, filing angle, round file diameter and cutting angle. Always use proper sharpening equipment

To sharpen cutting teeth use a file gauge round file. Switch off the engine as shown on the picture number 29.

Verify if chain is well tensioned. Reduce the pressure on the return stroke. File cutting teeth from the inside face. File all the teeth on one side first, then turn the chain saw over and file the teeth on the other side. File all the teeth to the same length. During sharpening the file must be positioned so as determine the following three corners of the cutting: “A” upper angle 30° – 35° “B” external side angle 85° – 90° “C” internal side angle 60° 2. The file must be positioned and must work perpendicularly to the bar. In order to achieve very precise side angles position the file so that you vertically cross over the cutting edge of about 0,5 mm. Sharpen all the teeth of one side first then turn the saw over and repeat the operation. To obtain a uniform cutting surface in the wood, all the teeth must be sharpened to the same length. Pay attention not to reduce the size of the cutting teeth below 4 mm, if that is your case you need to replace the chain with a new one.
