- Open the vice according to the dimensions of the material to
be cut.
- Place the material to be cut in the vice and lock using the
handwheel. Make sure that the relative pawl is interlocked
with the rack.
- Free the hand lever and move the mobile belt-guiding arm as
close as possible to the piece to be cut (up to approx. 10mm)
then lock the hand lever.
- Make sure that the cutting angle corresponds to the desired
inclination and that the angling device is locked using the
relative lever (see paragraph 7.4 of chapter 7).
- Make sure that the hydraulic regulator (6) is fully closed, then
rotate counter clockwise to set the most suitable lowering
speed for the characteristics of the material to be cut. It is
advisable to always start from a cautionary speed and in-
crease subsequently if necessary.

- Always make sure that the vice is positioned at the extreme
right or left of the countervice to avoid accidental contact with
the frame.
- Before starting the cutting cycle it is advisable to move the
blade to approx. 10mm from the piece to be cut, using the
selector (5) if necessary.
- Press the pushbutton (3) to start the cutting cycle. Make sure
that the belt turns in the correct direction and that a sufficient
quantity of cooling liquid exits.
NB: The weight of the blade-carrying frame causes it to lower
automatically without needing the intervention of Operator. If
greater cutting pressure is necessary, modify the tightness of
the frame return spring (see paragraph 7.8 of chapter 7).
- Use the variator group handwheel to set the most suitable
cutting speed for the material to be cut. This operation must
always be carried out while the motor is running).
To set the necessary speed, refer to the plate applied on-
board the machine or shown below.
- Press the emergency pushbutton if incorrect manoeuvres are
made, or if the cutting cycle is to be stopped.
- When finished cutting, the frame stops in the lower position.
Use the selector (5) to raise the frame.
NB: Do not use the sawing machine at full material dis-
charge speed during the first 50 working hours.
Keep a safe distance from the cutting area during machine
operation.
The sawing machine is now ready to start working. Please
remember that the CUTTING SPEED and the TYPE of blade
when combined with suitable frame lowering have a determi-
nate effect on the cutting quality and machine return (for more
information on this topic, refer to the "Material classification
and blade choice" chapter)
- When starting to cut with a new blade, it is necessary to
exert a light pressure on the piece during the first two or
three cuts, in order to use a cutting time that is almost
double the normal one (refer to the
Blade breaking-in para-
graph in the "Material classification and blade choice" chap-
ter further on in this manual).
- Use the red emergency pushbutton (1) when dangerous con-
ditions or faults in general arise. Doing so immediately inter-
rupts machine operation.
