4.3 Unsuitable material :
Materials unsuitable for this machine are all those not specified
in paragraph 4.2.
In any event, before using the saw with materials other than
as specified by the manufacturer for this saw model, contact
IMER INTERNATIONAL S.p.A.
- Use of this machine with workpieces outside the
specified dimensions is strictly prohibited and constitutes
a hazard for the operator.
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, fire or underground.
The saw is not fitted with specific lighting and therefore the
workplace must be sufficiently lit for this purpose.
The power lines must be laid to prevent any possible damage.
Never stand the saw on the power supply cable.
Ensure that the electrical connection is protected against the
risk of water 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 specialised 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
performance 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 efficient working order.
3.
Keep the machine clean: general cleaning
(and the work surfaces in particular) represents an
important safety factor.
4.
Always stop the machine and disconnect from
the power supply before cleaning or removing any
protection device (for maintenance or disassembly
purposes).
If water jets are used for cleaning, never point jets
directly at the power supply unit or electric motor.
5.
Remove rings, watches, bracelets or ties before
using the machine; 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.
6.
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)
7.
Always use personal protection devices such
as safety goggles, suitably sized gloves, ear muffs or
plugs and hair caps when necessary.
8.
Use original diamond blades as recommended
by the manufacturer to ensure optimal performance of
the machine.
9.
Always keep hands well away from the working
zone while the machine is running; before removing
workpieces from the blade area, always press the stop
pushbutton to shut down rotation.
10.
The instructions in this manual are aimed at
machine users (operators, maintenance engineers).
11.
Never use diamond blades that are chipped or

is placed on a stable surface with a maximum
inclination of 5°.
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 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.
machine, turn it off via the main switch and disconnect
from the power supply to prevent inadvertent start-up
and isolate all machine electrical circuits.
8. MACHINE INSTALLATION
8.1 Lifting and handling
The Combi 250 VA saw weights 38 Kg and can be moved by
means of the side handles on the tank (ref.N fig.5).
8.2 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.
inserts on the tank base and thus secured.
The correct side for the operator is as shown in Fig.3 position X.
In the event of moving the saw, take care to secure the head
by means of the fixing knobs (ref.O, L fig.7) and carry the
machine by means of the handles on the tank (ref.N fig.5)
after disconnecting the power supply.
moving the machine.
8.3 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 fitting the safety catches (ref. U fig.
5), tighten the screws and self-locking nuts with the spanner
provided (ref. T fig.5) taking care to allow rotation of the legs.
8.4 Side roller assembling (optional kit p/n1188086)
The side roller table is supplied with side supports already assembled.
First of all it s necessary to fit 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 (fig. 8).
To fit the central support it s necessary to reverse the screw fitting
side of the stand which is aside the side roller table.
Then place the support, fitting it inside the screw and tighten it so to
hold the table. Then tighten the nut.

Never use blades over the rotation speed
Use exclusively water-cooled continuous rim
Never dry cut material or cut when cooling
Ensure that the machine, with or without stand,
- Before performing maintenance or repairs to the
- Always empty the tank before moving the machine.
- Ensure that the stand is positioned on the relative
- Always remove the plug from the mains power before
