IMER SMART CUT 350 Manual De Uso & Mantenimiento página 4

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
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.
4. Always use personal protection devices such as safety goggles,
suitably sized gloves, ear muffs or plugs and hair caps when
necessary.
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: the general cleanliness of the machine
(especially its work tables) is an important factor in its safety.
8. 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.
9. Use genuine diamond blades as recommended by the
manufacturer to ensure optimal performance of the machine.
10. Use exclusively water-cooled discs of a type 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
manufacturer.
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
supplied with the machine (1").
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 SMART CUT 350 14" has been constructed taking into account
current harmonised European safety standards.
According to the "machinery directive" 2006/42/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
supply to prevent inadvertent start-up and isolate all machine
electrical circuits.
8. MACHINE INSTALLATION
- Always remove the plug from the mains power before moving
the machine.
- Always empty the tank before moving the machine.
8.1 Positioning
The machine must be placed on a smooth surface that is at least as
large as its frame, or supported on its legs.
In the event of moving the saw, take care to lock the head by means
of the knob
(Fig.1, Ref.D), lock the carriage with its cotter pin (Fig.1, Ref.N) and lift
the machine by the handles machined into the frame (Fig.1, Ref.O)
after having shut off its power supply.
8.2 Opening the legs.
To open the legs, proceed as follows: raise the machine at the rear
(Fig.1, Ref.1), push the leg in the direction of the arrow (Fig.1, Ref.2)
to move the bolt (Fig.1, Ref.3) away from the stop, turn it to open it
(Fig.1, Ref.4) and snug the bolt into the slot (Fig.1, Ref.5). Now rest

the machine on the ground. Now do the same at the front end of the
machine. To close the legs, reverse the procedure.
8.3 Lifting and handling
The SMART CUT 350 14" sawing machine weighs 82 Kg and can be
moved by hand, lifting it with the handles machined into its frame or with
a hoist, with ropes hooked into the indicated attachment points (Fig.1,
Ref.P). The wheels (Fig.1, Ref.Q) are an aid to loading the machine onto
a truck with a mobile platform.
9. ELECTRICAL CONNECTION
- Ensure that voltage corresponds to machine dataplate
specifi cations.
The power supply line must be equipped with current overload protection
(e.g. thermal cutout) and protection against indirect contact (e.g. residual
current circuit breaker). Connect the machine to an effi cient 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).

SMART CUT 350 14"
Connect the saw plug to the mains and tighten the mechanical retainer
ring with IP67 protection rating.
The saw is now ready for operation.
10. SAW START-UP
Connect the mains power cable to the plug on the electrical panel Now
start the sawing machine with the switch on the electrical cabinet over
the motor, composed of two buttons: green for start, red for stop.
The switch is fi tted with low voltage protection; in the event of accidental
power failure, press the green button again to resume operation.
In the event of an emergency, press the protruding red pushbutton to
shut down the machine and disconnect the plug from the power mains.
THERMAL CUTOUT
- The electric motor is protected against overload by a thermal
cutout; in the event of overheating this device shuts down the
motor. Cool the motor and restart the machine with the switch.
11. MACHINE USE
11.1 Operation
The correct side for the operator is shown in fi g.3 ref.X.
Fill the water tank to the maximum level (approx. 40 litres). Connect the
machine to the power mains and start as described in paragraph 10.
Open the valve (Fig.1, Ref. M) and make sure there is a suffi cient fl ow
of cooling water to the diamond blade.
11.2 Cutting
Rest the material to be cut on the cutting table against the stopper.
Set the required inclination using the goniometer. To adjust the cutting
head height, loosen the handwheel (Fig.1, Ref. D), position the head
at the required height, then fully tighten the handwheel. Start the saw
as described in paragraph 10. To make the cut, place the part to be cut
(Fig.3, Ref.D) on the carriage, then move the carriage up to the disc. If
the feed speed is too fast in relation to the thickness and hardness of the
material the blade might stop turning. In this case, release the disc as
quickly as possible by moving the carriage back until the disc recovers
its nominal rotation speed. Resume cutting, adjusting the feed speed
according to the characteristics of the material.
- Ensure that the tank is kept full during all work phases and in
the event of prolonged work intervals replace water regularly and
remove all processing residue.
