To file the saw chain, push the file in the direction of the arrow. When pulling it back, be careful not to touch the cutters with the file.

File

Saw chain

After a saw chain has been filed two or three times, the “raker” (see Fig. 24) may need to be filed down slightly. This is because the raker acts as a depth gauge for the cutters. As the cutters are filed, they lose some height due to their angled shape. Eventually, the cutters will become lower than the depth gauge and consequently, will not be able to cut. To remedy this, use a flat file to file the tops of the rakers so that they are about

0.5mm (0.025”) below the tips of the cutters (see Fig. 24). Be careful not to file the rakers excessively or the cutters will be allowed to take too large of a “bite”, causing the tool to stall or snag in the cut.
