STOPPING THE SAW
- The saw can be stopped by pressing the button on
the electrical panel (ref.10,tab.1).
13
DISC ASSEMBLY
- Cutting discs must only be removed or fitted when
the machine is stopped and the power supply is
disconnected.
1. Check that the vertical movement of the cutting head is
locked (ref.11,tab1).
2. Unscrew the four screws that secure the movable part of
the disc guard using the wrench supplied.
3. Loosen the locknut by turning it clockwise (left-hand thread)
using the wrench provided.
4. Remove the movable flange. Check the flanges, arbor and
disc for damage.
- Do not use damaged discs, with missing sectors.
- Use only discs that are suitable for the rpm shown
on the machine data plate.
- Check that the direction of rotation of the disc is the
same as marked on the disc guard.
5. Center the disc on the fixed flange, position the movable
flange and correctly tighten the disc locknut by turning it
anticlockwise (left-hand thread).
6. Refit the movable part of the disc guard, securing it with the
respective screws.
- Check that the disc guard is firmly secured.
- An incorrectly assembled disc can cause damage to
the machine and to people.
- Note that the disc must have external diameter of
600 mm, central hole diameter of 25.4 mm and maximum
thickness of 3.5 mm.
- Make sure that the disc to be used is suitable for the
material to be cut (para.3).
- It is forbidden to use discs for cutting wood.
14
USE
- Leave at least 1.5 m of free space around the
machine to operate safely.
• Only use the machine within the temperature range 0
- 40 °C.
• Do not allow anyone else to remain in the vicinity of the
machine during cutting.
• Do not use the machine in areas exposed to the risk of fire.
The cutting process may generate sparks, which could cause
fires or explosions.
• Transport and position the
machine only after disconnecting it
from the power supply.
• Always make certain that the disc is not in contact with
anything before starting the motor.
- Check that the disc guard is in place.
The machine must not be used in closed or
underground environments or where there is a risk of fire
or explosion.
• Before starting work, fill the tank with water. Top up the level
during use, whenever necessary. The pump must always
remain submerged.
• Insert the power plug.
- It is absolutely forbidden to remove the guards of
the machine.
- The electric motor is protected against thermal
overload: this protection intervenes by stopping the
machine, after which it is necessary to wait for the time
necessary to the thermal device to cool down before it is
possible to restart the machine.
14.1
Vertical movement of the disc
- All disc adjustment operations must be carried out
with the saw switched off and disconnected from the
power supply.
To raise or lower the cutting head, loose the locking lever,
move the cutting disc to the desired height from the cutting
table and then re-tighten the lever (fig.6).
- Make certain that the locking knob is properly
tightened before starting the work.
14.2
Cutting
During cutting operations it is mandatory to place both hands
on the push knobs (fig.5).
It is also mandatory to wear the necessary personal protective
equipment such as:
- gloves
- eye protection
- earphones for noise protection
- Check the alignment of the disc with the cutting
line.
1. Place the piece to be cut on the carriage,
so that it is stable and up against the fixed stop of the carriage.
2. Start the motor.
3. Wait until the water reaches the disc.
4. Make sure that nothing is in the cutting area that can
obstruct the cutting operation.
5. Start cutting.
6. The horizontal cutting movement is achieved by manually
moving the carriage towards the cutting disc.
- The greater the cutting height, the greater the effort
required from the cutting disc. Therefore the operator
must control the forward speed of the carriage so as not
to overload the motor. The correct speed also depends on
the characteristics of the material to be cut (hardness,
toughness, etc.).
14.3
Cutting from above
Unlock the cutting head by releasing the lock lever; position
the piece to be cut, start the saw and bring the disc
downwards using the handle located on the cutting head
(fig.7).
