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 four important
factors to remember.
1 Filing angle
2 Cutting angle
12 –
Canadian
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.
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 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.
