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 chips will be very small. If the chain 
is very blunt it will produce wood powder and no chips 
or shavings.

•

A sharp chain eats its way through the wood and 
produces long, thick chips or shavings.

•

The cutting part of the chain is called the cutter and 
consists of a cutting tooth (A) and the depth gauge 
(B). The cutters cutting depth is determined by the 
difference in height between the two (depth gauge 
setting).

When you sharpen a cutting tooth there are four important 
factors to remember.

Filing angle

Cutting angle

File position

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.
