Sharpening the clearing blade
!
WARNING!
Incorrect cutting equipment or an
incorrectly sharpened blade increases
the risk of kickback.
• See the cutting
equipment’s packaging
for correct filing
instructions.
• A correctly sharpened
blade is a prerequisite for
working efficiently and to
avoid unnecessary wear to
the blade and clearing
saw.
• Make sure that the blade
is well supported when
you use the file. Use a 5.5
mm round file with a file
holder.
• The sharpening angle is
15°. Every other tooth is
sharpened to the right
and the intermediate
tooth to the left. When
the blade has been heavily
pitted by stones the upper
side of the teeth can, in
exceptional cases, need to
be dressed using a flat file.
In such cases this takes
place before sharpening
with the round file.
Dressing the top side
must be carried out
equally for all teeth.
• Adjust the setting. This
should be 1 mm.
