5. OPERATION SAFETY
- Before using the saw, ensure that all protection devices are
fi tted.
- Never use the saw in environments subject to the risk of
explosions or fi re.
The saw is not fi tted with specifi c lighting and therefore the workplace
must be suffi ciently 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 effi cient earthing system is installed.
2. Work only with all protection devices fi tted 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 specifi ed 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 specifi ed by the ma-
nufacturer.
13. Do not use reduction rings to adapt the hole of the disc on the
fl ange. Only use discs with hole corresponding to the fl ange 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 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 fi xed guards, secured by means of screws
and protections that prevent access to moving or dangerous parts.
All fi xed guards, covers, shields fi xed 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 modifi ed 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 Positioning
The machine must be placed on a smooth surface that is at least as
large as the tank, with the saw on the relative stand.
- Ensure that the stand is positioned on the relative inserts on
the tank base and thus secured.
In the event of moving the saw, take care to secure the head by means
of the fi xing knobs (ref.L, fi g.1) and carry the machine by means of the
handles on the tank (ref.I, fi g.1) after disconnecting the power supply.
- Always remove the plug from the mains power before mo-
ving the machine.
8.2 Stand assembly
The stand is supplied disassembled. Firstly, join the two parts of each
leg making sure that the inner and outer holes are aligned. Join the two
legs fi tting the safety catches (ref.3-4, fi g. 6), tighten the screws and
self-locking nuts with the spanner provided (ref.6, fi g.6) taking care to
allow rotation of the legs.
8.3 Lifting and handling
The Combi 250 VA saw weights 33 Kg and can be moved by means of
the side handles on the tank (ref.I, fi g.1).
- Always empty the tank before moving the machine.
8.4 Side roller assembling (optional kit p/n 1188166)
The side roller table is supplied with side supports already assembled.
First of all it's necessary to fi t such supports
inside the proper seats housed alongside the saw up to the stop. Now
lower the side roller table up it's levelled to the saw's table (fi g.7).
To fi t the central support it's necessary to reverse the screw fi tting side
of the stand which is aside the side roller table (ref.8, fi g.7). Then place
the support, fi tting it inside the screw and tighten it so to hold the table.
Then tighten the nut.
