SAFETY INSTRUCTIONS
• 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.
Sharpening cutting teeth
To sharpen cutting teeth you will need a round file and a file
gauge.
• Check that the chain is correctly tensioned. A slack chain
will move sideways, making it more difficult to sharpen
correctly.
• Always file cutting teeth from the inside face outwards.
Reduce the pressure on the return stroke. File all the teeth
on one side of the bar first. Then turn the saw over and file
the remaining teeth from the other side.
