Sharpening cutting teeth
To sharpen cutting teeth you will need a round file and a
file gauge.
• 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 outwards.
Reduce the pressure on the return stroke. File all the
teeth on one side of the bar first. Then turn the saw
over and file the remaining teeth from the other side.
• File all the teeth to the same length. When the length
of the cutting teeth is reduced to 5/32 inch (4 mm) the
chain is worn out and should be replaced.

General advice on setting raker clearance
• 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.
GENERAL SAFETY PRECAUTIONS
• On a low-kickback cutting link the front edge of the
raker lip is rounded. It is very important that you
maintain this radius or bevel when you adjust the raker
clearance.
• We recommend that you use our raker gauge to
achieve the correct clearance and bevel on the raker
lip.
WARNING! The risk of kickback is
!
increased if the raker clearance is too
large!
Setting the raker clearance
• Before setting the raker clearance the cutting teeth
should be newly sharpened.
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.
• To adjust the raker clearance you will need a flat file
and a raker gauge.
• Place the gauge over the raker lip.
• Place the file over the part of the lip that protrudes
through the gauge and file off the excess. The
clearance is correct when you no longer feel any
resistance as you draw the file over the gauge.
