GENERAL SAFETY PRECAUTIONS
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.
1 Filing angle
2 Cutting angle
3 File position
4 Round le diameter
It is very difcult to sharpen a chain correctly without the right
equipment. We recommend that you use our le 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.
Sharpening cutting teeth
To sharpen cutting teeth you will need a round le and a le
gauge. See instructions under the heading Technical data for
information on the size of le and gauge that are
recommended for the chain tted to your chain saw.
Check that the chain is correctly tensioned. A slack chain
will move sideways, making it more difcult to sharpen
correctly.
Always le cutting teeth from the inside face. Reduce the
pressure on the return stroke. File all the teeth on one side
rst, then turn the chain saw over and le the teeth on the
other side.
File all the teeth to the same length. When the length of
the cutting teeth is reduced to 4 mm (0.16") the chain is
worn out and should be replaced.
General advice on adjusting depth gauge setting
When you sharpen the cutting tooth (A) the depth gauge
setting (C) will decrease. To maintain optimal cutting
performance the depth gauge (B) has to be led down to
achieve the recommended depth gauge setting.
See instructions under the heading Technical data to nd
the correct depth gauge setting for your particular chain.
!
WARNING! Departure from the sharpening
instructions considerably increases the risk
of kickback.
!
WARNING! The risk of kickback is increased
if the depth gauge setting is too large!
