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.
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 (5/32") 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
!
WARNING! Departure from the
sharpening instructions considerably
increases the risk of kickback.
