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 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).

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.
WARNING! Departure from the

sharpening instructions considerably
increases the risk of kickback.
Sharpening cutting teeth
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 chainsaw.
•
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 chainsaw and file the teeth
on the other side.
