10. INSTALLATION (fig. 4)
- Lift the machine out of its package using slinging equipment with 4
rope legs. Fix the hooks to the relative attachments.
- Install the machine on a completely even and stable surface.
- Release the carriage from the lever that secures it to the frame.

11. ELECTRICAL CONNECTION

- Ensure that there is an overload cutout device
fitted up-line on the power line.
- Ensure that the mains voltage corresponds to that specified
for the machine: 380V/50Hz - 415V/50Hz. The electrical power
cable must be suitably sized to avoid voltage drops. Cable
drums must not be used.
Connect the machine to an efficient earthing system.
The size of the power cable wires must be based on operating
current and length of the power line to prevent excessive
voltage drops (ref.Table 3).
Cables used on construction sites must be fitted with suitable
external sheathing that is resistant to wear, crushing and
extreme weather conditions (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 sufficient cooling water.
3 - Ensure that the power circuit corresponds to the requirements
as indicated in Section 11 "Electrical connections"
4 - Connect the machine to the power supply
5 - Press the black switch (Ref. 7, fig. 1).
- If rotating direction is opposite to the arrow on the
guard, stop the machine and reverse the two
wires inside the feeding plug: such operation must be
carried on by reliable persons
6 - adjust the flow of cooling water by turning the cock next to
the blade guard (do not perform cutting without water).
7 - Check that the direction of blade rotation corresponds to that
indicated by the arrow on the blade guard.
8 - If all is in order, proceed with cutting.

13. EMERGENCY STOP

- In an emergency, stop the machine by pressing the
stop control switch.
- The motor is fitted with an overload cutout device.
If the motor overheats, it will automatically shut down.
Allow the motor to cool and press the black switch on the
overload cutout device to restart (Ref. 7, fig. 1).
- The motor is protected against automatic re-start
after interruptions due to power failure. To resume
operation, when power is re-connected, press the black
switch on the overload cutout device (Ref. 7, fig. 1).
14. BLADE INSTALLATION (Fig.5)
By means of a hex wrench no.10, unscrew the 5 screws that lock
the moving blade guard (ref.3). Loosen the locknut (rif.1) by rotating
clockwise (left thread). Remove the mobile flange (rif.2) and check
that the flanges, disc shaft and blade are not damaged.
- Never use worn blades or blades with missing segments.
- Only use blades that are designed for the number of
revolutions indicated on the machine rating plate.
- Check that blade rotation corresponds to that indicated
on the blade guard.
Centre the blade against the fixed flange, position the mobile flange
and tighten the blade locknut fully down by rotating anticlockwise
(left thread). Refit the moving blade guard, tightening the 5 screws
(ref.3).
- Ensure that the blade guard (ref.3) is locked securely
into position.

suitable for the material to be cut.
15. USE
operate in full safety.
- Do not allow other persons to approach the machine during
cutting.
- Never use the machine in fire-risk areas. Sparks can cause fire
or explosions.
- Make sure that the machine is switched off before positioning
or handling.
- Always ensure that the blade is free of any contact before
start-up.
Before starting work, fill the water tank. Top up during operation
whenever necessary: N.B. the pump suction hose must
always remain immersed in water.
- Insert the plug in the power socket.

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 machine.
carrying out blade adjustment.
15.1 VERTICAL MOVEMENT OF THE DISK.
To raise or lower the cutting wheel, turn the crank (ref.11, fig.1)
until the wheel is at the required height above the cutting table.
The wheel can also be lowered by pressing the pedal (ref.16,
fig.1); when the pedal is released the cutting wheel will return to
the position originally set using the crank.
before starting work.
15.2 POSITIONING FOR 45° CUTS.
To machine a 45° cut, it is necessary to use the 45° support.
Place the 45° support on the cutting table in the position required,
fix the support to the carriage by locking the flywheel provided,
then position the piece to be cut, after which it is possible to start
the motor and commence cutting operations
15.3 CUTTING
For safe use of the machine when cutting, push the carriage
forwards as the cut advances, placing your hands to the two
sides of the carriage. Never push directly on the piece to be cut.
line.
- Place the workpiece on the worktable (ref. 8, fig. 1), resting
firmly against the stop.
- Start the engine.
- Wait until the water reaches the blade.
- Begin cutting.
- Horizontal cutting movement is carried out by pulling the carriage
towards the blade.
to greater stress. To avoid overloading the engine, the
operator should continually check blade feed speed. The
speed will also depend on the characteristics of the
material being cut (hardness, toughness etc.).
