B. Sharpening
cutting tooth
To sharpen cutting teeth you
will need a ROUND FILE
and a FILE GAUGE.
1. Check that the chain is
correctly tensioned. A
slack chain is difficult to
sharpen correctly.
2. Always file cutting teeth
from the inside face,
reducing the pressure on
the return stroke.
File all the teeth on one
side first, then turn the
saw over and file the teeth
on the other side.
3. File all the teeth to the
same length. When the
length of the cutting
teeth is reduced to 4 mm
(.16") the chain is worn
out and should be
replaced.

C. General advice on setting raker
clearance
• When you sharpen the
cutting teeth you reduce
the RAKER
CLEARANCE (cutting
depth). To maintain
cutting performance you
must file back the raker
teeth 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 the use of
a 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!
