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.
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.
•
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 teeth you reduce the
raker clearance (=cutting depth). To maintain optimal
cutting performance you must file back the raker lip to
the recommended height. See instructions under the
heading Technical data to find the correct depth gauge
setting for your particular chain.
Adjustment of depth gauge setting
•
The cutting teeth should be newly sharpened before
adjusting the depth gauge setting. We recommend
that you adjust the raker clearance every third time
you sharpen the chain. NOTE! This recommendation
assumes that the length of the cutting teeth is not
reduced excessively.
•
You will need a flat file and a depth gauge tool. We
recommend that you use our depth gauge tool to
acheive the correct depth gauge setting and bevel for
the depth gauge.
!
WARNING! Departure from the
sharpening instructions considerably
increases the risk of kickback.
!
WARNING! The risk of kickback is
increased if the raker clearance is too
large!
