9. TRANSPORTATION
- Before removing the panel saw, lock the carriage using the
stop (ref.4, fi g.4).
For hoisting the machine use a brace with three arms and (ref.1, fi g.4),
inserting the hooks in the special couplings (ref.3, fi g.4). When transpor-
ting the machine with a fork lift, insert the left fork in the slot provided
(ref.2, fi g.4).
As the machine is fi tted on wheels, it can be moved by hand on fl at
surfaces as follows:
1. make sure that the front wheel brakes are released.
2. make sure that the piece holder carriage is clamped with the special
ratchet (ref. 4, fi g. 4).
3. pull the machine by hand using the piece holder carriage grip; move-
ment (also round corners) is facilitated by the front castor wheels.
10. INSTALLATION
1. Install the machine on a completely even and stable surface.
2. Block the front wheels with the brakes.
3. Release the carriage from the lever that secures it to the frame (ref.4,
fi g.4).
11. ELECTRICAL MAINS CONNECTION
- Make certain that a residual current device and miniature
circuit breaker are installed on the electrical power line.
11.1 Connecting versions with motor 230V/50Hz
Ensure that the supply voltage corresponds to machine dataplate speci-
fi cations. At full load it must be between 205V and 240V.
- To supply the machine it is necessary to use a 2-pole +
ground cable in order to ensure the machine's connection to the
site's equipotential system.
11.2 Connecting versions with motor 380V/50Hz
Ensure that the supply voltage corresponds to machine dataplate speci-
fi cations. At full load it must be between 370V and 430V.
- To supply the machine it is necessary to use a 3-pole +
ground cable in order to ensure the machine's connection to the
site's equipotential system.
11.3 Sizing the power supply cable
The power supply line must be suitably sized to prevent voltage drops.
Do not use cable winders. The electric cable wire size must take into
account the operating currents and length of the line to avoid excessive
voltage drops (table 4).

Cables used on construction sites must be fi tted with suitable external
sheathing that is resistant to wear, crushing and extreme weather condi-
tions (for example H07RN-F).
- All power supply installations must comply with CEI 64-8
standards (harmonised document CENELEC HD384).
12. MACHINE START-UP
Before connecting the machine to the power supply:
1. Ensure that the metal structure is connected to an earthing plant as
indicated in Section 7 "Safety Precautions".
2. Ensure that the tank contains suffi cient cooling water (min. 60 l; max.
90 l).
3. Ensure that the power circuit corresponds to the requirements as in-
dicated in Section 11 "Electrical connections"
4. Connect the machine to the power supply
5. Turn the start-stop selector to the start position (star connection). Wait
for 5 sec. and turn to the running position (delta connection).
6. Check that the direction of blade rotation corresponds to that indica-
ted by the arrow on the blade guard.
- The machine comes with a phase inverter (table.4, page.29).
If the blade direction of rotation is in the opposite direction to the

arrow on the protective guard, turn off the saw and disconnect the
power socket from the wall plug on the machine. Insert the phase
inverter on the latter and connect the power socket again.
7. adjust the fl ow of cooling water by turning the cock next to the blade
guard (do not perform cutting without water).
8. If all is in order, proceed with cutting.
13. EMERGENCY STOP
- In the case of an emergency, stop the machine pressing the
special red mushroom button. To start again, reset the mushroom
button turning it clockwise and turn the selector to zero, then repe-
at point 12.5 (ref.9, fi g.1).
14. BLADE INSTALLATION
- The disk assembly operation must be carried out after stop-
ping the machine and disconnecting the power socket.
1. Slacken the fastener and remove the water pipe (ref. 4, fi g. 5).
2. Slacken the three screws fastening the mobile part of the disk guard
using the special wrench provided (ref.3, fi g.5).
3. Slacken the locking nut (ref. 1, fi g. 5) turning it clockwise (left-hand
thread).
4. Remove the mobile fl ange (ref. 2, fi g. 5). Check that there is no dama-
ge on the fl anges, disk shaft and disk.
- Never use worn blades or blades with missing segments.
- Only use blades that are designed for the number of revolu-
tions indicated on the machine rating plate.
- Check that the direction of rotation of the disk is as shown
on the disk guard.
5. Centre the disk on the fi xed fl ange, position the mobile fl ange (ref. 2,
fi g. 5) and tighten the disk locking nut correctly (ref. 1, fi g. 5) turning it
counter-clockwise (left-hand thread).
6. Refi t the mobile part of the disk guard, fastening with the correspon-
ding screws (ref.3, fi g.5).
7. Put the water pipe back in place and tighten the fastener until the pipe
is clamped (ref.4, fi g.5).
- Ensure that the blade guard (ref.3) is locked securely into
position.
- An incorrectly installed blade, or a screw insuffi ciently
tightened can provoke damage to the machine
or injury to persons.
- Note that the blade must have an external
diameter of 750 mm, a central hole diameter of
25.4 mm and max. thickness of 4 mm.
- Check that the blade to be used is suitable
for the material to be cut.
- Do not use blades for wood (fi g.6).
15. USE
- Leave a space of 150 cm around the machine to operate in
full safety.
• Use the machine within a temperature range of 0 – 40 °C.
• Do not allow other persons to approach the machine during cutting.
• Never use the machine in fi re-risk areas. Sparks can cause fi re or
explosions.
• Make sure that the machine is switched off before positioning or han-
dling.
• Always ensure that the blade is free of any contact before start-up.
- Ensure correct installation of all protective devices.
• Before starting work, fi ll the water tank. Top up during operation whe-
never necessary: N.B. the pump suction hose must always remain im-
mersed in water.
• Insert the plug in the power socket.
- For safety purposes the removal of protective guards from
the machine is strictly prohibited.
- The machine is protected against overload: this protection
triggers stopping the machine, after which the time necessary for
the overload to cool must pass before it is possible to restart the
