GENERAL SAFETY PRECAUTIONS
English – 13
• 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 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
inf
or
mation about sharpening your chain.
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 mo
v
e sideways, making it more difficult to sharpen
correctly.
• Always file cutting teeth from the inside face. Reduce the
pressure on the retur
n stroke. File all the teeth on one
side first, then turn the chain saw and file the teeth on the
other side.
• File all the teeth to the same length. When the length of
the cutting teeth is reduced to 0.16 inch (4 mm) the chain
is w
or
n 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 filed down to
achieve the recommended depth gauge setting. See
instructions under the heading Technical data to find 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!
