5.4 SHARPENING THE BLADE
Sharpen the blade regularly as soon
as a decrease in cutting is felt.
Proceed as follows:
1. ensure the machine is turned
off by pressing the stop
blade button;
2. (Fig. 12), loosen the knob (1),
raise (a) the sharpening device
(2) and rotate by 180° (b).
Then let it reach the end of
the run (c) so that the blade
is between the two wheels.
Lock the knob
3. start the machine, pressing
the start blade button;
4. (Fig. 13) press the button (3),
allow the blade to turn in
contact with the wheel for
about 30/40 seconds so that a
slight burr forms on the edge
of the blade;
5. (Fig. 13) press both buttons (3
and 4) at the same time for
3/4 seconds, then release
them both at the same time;
6. (Fig. 14) once sharpening has
been completed, switch the
machine off and put the
sharpening device back in its
original position, following the
procedure in reverse order.
7. after sharpening, it is
advisable to clean the wheels
(see paragraph 6.2.3);
N.B.: Do not perform deburring for
more that 3/4 seconds to prevent the
edge of the blade from being twisted
and becoming damaged.
