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, thic
k 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
f
actors 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
r
ight 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
inf
ormation about sharpening your chain.
