General information on sharpening cutting teeth
•Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the cuttings will be very small. If the chain is very blunt it will not produce any cuttings at all. Wood powder would be the only result.
•A sharp chain eats its way through the wood and produces long, thick cuttings.
•The cutting part of the chain is called the cutting link and this consists of a cutting tooth (A) and the raker lip (B).The cutting depth is determined by the difference in height between the two.

•When you sharpen a cutting tooth there are five important factors to remember.
- Filing angle
-Cutting angle
-File position
-Round file diameter
-File depth

It is very difficult to sharpen a chain correctly without the right equipment. We recommend that you use our file gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.
WARNING! The following faults will increase
!the risk of kickback considerably: File angle too large
Cutting angle too small
File diameter too small
