An ideal condition for correct operation over time is for the teeth of the
blade to protrude from the face of the flywheels (fig. 14-2).
The machine is factory set for the maximum blade width.
When, after subsequent sharpening, this width reduces, it is
possible to restore the original condition by tilting the top flywheel
by means of the handle
U (fig. 14-3).
It will then be possible to perfect the tension of the blade using the
gauge
H (fig. 14-1, 14-1-2). The blade-tightening handwheel will be
turned until the gauge pointer reaches the value corresponding to
the actual width of the blade.
If this, when it is correctly stretched, has changed its position on
the face of the flywheel, it is necessary to repeat the tilting
adjustment of the top flywheel.
When the operation is complete, return all the guards to their
original positions and close the doors; with star-delta starting,
return the master switch knob
I to the "0" position.

14. USING THE MACHINE
14.1. Fitting and adjusting the blade
Open the doors with the machine at a standstill.
With the machine stationary, open the doors, the protection door
under the table block, and the transparent protection
E (fig. 14-1)
of the top blade guide (pull, then turn, revealing the slot through
which the blade passes).
If the machine is equipped with an electric brake the flywheels are
normally idle and it is definitely possible to go ahead and install the
blade.
Whereas, the machine fit self-braking motors so it is necessary to
release the brake beforehand. This is done keeping pushed the
yellow button
Z (fig.13-8), or with the master switch on position "0",
pressing the master switch I (fig. 13-4) and turning it to the left (onto
position F). The yellow indicator light L (fig. 13-7) close to the
control signals this situation of the machine.
Move the thrust wheel of the blade guide(s) fully back and, having
inserted the blade in its seat, carefully check it is arranged well along
its entire path and does not come into contact with metal parts.
Partially stretch the blade with the handwheel
A (fig. 14-1, 14-1-2) and
then turn the flywheels by hand until it has reached a stable
position.
