Number of drive links.

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 four important 
factors to remember.

1

Filing angle

2

Cutting angle

3

File position

4

Round file diameter

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.

See instructions under the heading Technical data for 
information about sharpening your chain.

To sharpen cutting teeth you will need a round file and a file 
gauge. See instructions under the heading Technical data for 
information on the size of file and gauge that are 
recommended for the chain fitted to your chain saw.

•

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. Reduce the 
pressure on the return stroke. File all the teeth on one side 
first, then turn the chain saw and file the teeth on the other 
side.
