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 ¿ 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 ¿ 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 suf¿ cient À 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. There is a stop next
to the handwheel (Fig.1, Ref.D), which must be moved to adjust for the
cutting depth of the disc being used (350mm or 400mm) to prevent the
carriage itself being cut. With the 350mm disc, set the stop as shown in
(Fig.3, Ref.B). With the 400 mm disc, set the stop as shown in (Fig.3,
Ref.C). 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.
12. MAINTENANCE
12.1 Foreword
Routine maintenance operations can also be performed by non-
specialised personnel provided that all safety standards speci¿ ed in the
relative sections of this manual are observed at all times.
12.2 Cleaning the machine
The machine should be cleaned exclusively when it is stationary.
- All power switches must be
set to "0" and plugs must be disconnected from the mains.
1. Never use compressed air; this could cause in¿ ltration of dust or
residue into corners.
2. Ensure that the cooling water nozzles are not obstructed.
3. In particular, it is recommended that you change the cooling water in
the tank every day.
4. Do not use detergents or lubricants.

12.3 Cleaning the tank
Clean the tank in the event of build-up of sediment on the base, or at
least once a day. Failure to clean the tank could impair operation of
the immersion pump used for circulation of the diamond blade cooling
water.
To clean out the tank, remove its plug and rinse it out with a jet of water
- take care not to direct water onto electrical equipment.
12.4 Cleaning the cooling water supply circuit
At regular intervals (or when the À ow rate of the blade cooling water is
reduced) clean the cooling water supply circuit.To do this, disassemble
the delivery nozzle located inside the blade guard (Fig.1, Ref. E) and
clean in water.
Periodically clean the cooling water delivery line between the pump and
valve and blade guard using water.
12.5 Replacing the disc
The diamond blade is made of material that may be damaged when
subject to high temperatures, and therefore must be cooled during the
work phases.
To replace the blade, proceed as follows:
1. Block the vertical movement of the cutting head by tightening down
the handwheel (Fig.1, Ref.D).
2. Disassemble the front guard (Fig.1, Ref.E).
3. Loosen the locknut by rotating it clockwise (LH thread), using the 32
mm wrench supplied with the machine.
4. Move the cutting head forward slightly and incline to remove the blade
from its seat.
5. Ensure that there are no foreign objects between the ¿ xing À ange and
diamond blade. During disassembly, avoid use of tools that could dent
or deform the À ange.
6. Fit the new blade by proceeding in reverse order of the operation
described at point 4. Take special care to ensure the correct direction of
rotation of the diamond blade.
7. Tighten the blade locknut fully down by rotating anticlockwise (left
thread), to a torque of 40 Nm.
- Always disconnect the power plug before changing the disc.
12.6 Repairs
Repairs to the electrical installation must be performed exclusively
by specialised personnel. Use exclusively original IMER spare parts;
modi¿ cations to parts are strictly prohibited. The special design of
the M400 SMART ensures that no other maintenance other than that
speci¿ ed above is required. Ensure that the contacts of the power plug
and plug-switch assembly are ef¿
immediately
- In the event of activation of the differential circuit breaker,
check the machine and arrange for repairs if necessary exclusively
by specialised personnel.
12.7 Disposal of refuse
As regards disposal of processing waste, observe all current legislation
in the country of use.
13. RESIDUAL RISKS AND SAFETY NOTICES
Although the sawing machine has been manufactured fully in compliance
with current regulations, residual risks exist that cannot be eliminated
and involve the use of appropriate individual protection devices. The
machine is equipped with notices to indicate the residual risks and how
to avoid them.
