GENERAL SAFETY PRECAUTIONS
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 4 mm (0.16") 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.
• 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.
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.
!
WARNING! The risk of kickback is increased
if the raker clearance is too large!
