5. OPERATION SAFETY
- Before using the saw, ensure that all protection devices are
fitted.
- Never use the saw in environments subject to the risk of
explosions or fire.
The saw is not fitted with specific lighting and therefore the workplace
must be sufficiently lit for this purpose (min. 300 lux).
The power lines must be laid to prevent any possible damage.
Ensure that the electrical connection is protected against the risk of wa-
ter penetration in connectors. Use exclusively connectors and couplings
equipped with water spray protection.
Never use inadequate or makeshift electrical lines or cables without
earthing; if in doubt consult a specialised technician.
Repairs to the electrical circuit must be performed exclusively by specia-
lised personnel. Disconnect the machine from the power supply before
performing maintenance or repairs.
6. GENERAL SAFETY WARNINGS
Note that this machine has been designed to ensure optimal performan-
ce and maximum safety: however the operator must also guarantee this
level of safety by paying special attention to the machine throughout all
work phases.
1. Ensure that an efficient earthing system is installed.
2. Work only with all protection devices fitted correctly and in effi
-
cient working order.
3. Remove rings, watches, bracelets or ties before using the ma-
chine; these elements constitute a serious hazard to the operator.
Also ensure that sleeves are tight around the wrists, hair is tied
back and robust footwear is used.
4. Always use personal protection devices such as safety goggles,
suitably sized gloves, ear muffs or plugs and hair caps when ne-
cessary.
5. Never cut workpieces that have dimensions or weight that are
not suited to machine i capacity as specified by the manufacturer
(see point 4.2)
6. Always keep your hands away from the work areas when the
machine is running. Before taking any action to remove a piece
from close to the disc, stop rotation by pressing the stop button.
7. Keep the machine clean: general cleaning (and the work surfa-
ces in particular) represents an important safety factor.
8. Always stop the machine and disconnect from the power supply
before cleaning or removing any protection device (for maintenan-
ce or disassembly purposes). If water jets are used for cleaning,
never point jets directly at the power supply unit or electric motor.
9. Use genuine diamond blades as recommended by the manufac-
turer to ensure optimal performance of the machine.
10. Use exclusively water-cooled continuous rim blades suited to
the material to be cut.
11. Never dry cut material or cut when cooling water levels are low.
12. Never use blades over the rotation speed specified by the ma
-
nufacturer.
13. Do not use reduction rings to adapt the hole of the disc on the
flange. Only use discs with hole corresponding to the flange sup
-
plied with the machine (1" or 7/8").
14. Never use diamond blades that are chipped or deformed.
15. The instructions in this manual are aimed at machine users
(operators, maintenance engineers).
7. SAFETY DEVICES
The Combi 250/1000 VA(250/1500 VA) has been constructed taking into
account current harmonised European safety standards.
According to machine directive 98/37/EEC all safety devices have been
installed with the aim of safeguarding the operator.
7.1 Guards and safety devices
The machine is equipped with fixed guards, secured by means of screws
and protections that prevent access to moving or dangerous parts.
All fixed guards, covers, shields fixed by means of screws have been
envisaged to protect the operator (maintenance engineers, technicians
and others) from possible accidents cause by electrical discharge or
moving mechanical parts.
Therefore use of the machine with guards removed or modified in any
way is strictly prohibited.
- Before performing maintenance or repairs to the machine,
turn it off via the main switch and disconnect from the power sup-
ply to prevent inadvertent start-up and isolate all machine electri-
cal circuits.
8. MACHINE INSTALLATION
8.1 Set up
Remove the machine packing.
The machine can already be used, leaving the legs folded, resting its
frame on a sufficiently even surface at least as big as the tank.
Frame assembly:
1. remove the machine and tank from the folded frame.
2. remove the safety pins from the frame and open the legs.
3. put the safety pins back in the holes provided locking the legs in the
open position.
4. reposition the machine and tank on the frame.
- Make sure that the frame is positioned on a flat and even sur
-
face, capable of bearing the weight of the machine. The maximum
permissible gradient in all directions is 6°.
8.2 Handling
The Combi 250/1000 VA sawing machine weighs 57 Kg(250/1500 VA
80 kg) and can be moved using the side handles on the tank (ref.I,
fig.1). For short distances use the wheels fitted on the frame. For longer
distances, before moving the machine, close the frame reversing the
sequence of the operations described in point 8.1.
Every time the machine is moved, make sure the head is locked tighte-
ning the knobs (ref.L, fig.1).
- Always empty the tank before moving the machine.
- Always disconnect the power plug before moving the ma-
chine.
8.3 Additional table assembly (optional kit code 1188176)
The additional table can be installed to the left or right of the machine, or
on both sides at the same time.
First fit the cross member (ref.5, fig.6) to the bolts on the frame (ref.A,
fig.6) and secure it with the nut and washer (ref.6-7, fig.6). Secure the
other end of the cross member with the locking pin (ref.8, fig.6) on the
front legs.
Fit the strut (ref.1, fig.6) to the cross member, making sure that it locates
into the grooves, which hold it perfectly vertical.
Now install the additional table; it is supplied with the side mounts alre-
ady assembled. Fit the mounts into the provided cavities in the side
panels of the machine, making sure they are fully inserted. Now lower
the additional table until it is properly supported. Level the additional
table with that of the machine itself; to do this, move the strut to the left
or right along the cross member (fig.6).
- The use of additional tables without props can cause damage
to them.
9. ELECTRICAL CONNECTION
- Ensure that voltage corresponds to machine dataplate spe-
cifications.
The power supply line must be equipped with current overload protec-
tion (e.g. thermal cutout) and protection against indirect contact (e.g.
residual current circuit breaker).
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 (table
4).
