Thermal Cutout; Machine Use; Maintenance - IMER C 350 i-Power Handbuch

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
Move the head assembly towards the opposite side to the operator, up to
stop, then place the material being cut (Fig.7, Ref.A) against the stop on
the table. In case of angle cut, establish the desired angle using the pro-
tractor or by means of the laser pointer To adjust the height of the cutting
head, slacken the handwheel (Fig.7,Ref.B), position the head at the desi-
red height and tighten the handwheel Start the saw as described in par. 10
and, by means of the handle (Fig.7,Ref.C), slide the carriage to carry out
cutting. A forward speed that is too fast for the thickness and hardness of
the material can cause the blade to stop turning.In this case, free the blade
a quick as possible, shifting the carriage back in order to move the blade
away until it has regained nominal rotation speed. Resume cutting by adju-
sting the forward 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.
11.3 Cutting at an angle
Slacken the handwheels (Fig.7,Ref.D), tilt the cutting head and
retighten the handwheels, then proceed as described in the
previous point.
11.4 Laser pointer
The machine is equipped with a laser pointer that marks the cutting line
on the workpiece. The guide mark indicates the path of the cutting bla-
de. Maximum precision is obtained by matching the desired cutting line
with the laser guide mark. Perpendicular cuts on a side of the workpiece
do not require previous marking: just make sure the reference side is in
contact with the stop on the support table. Similarly, using the protractor
it is possible to cut at given angles. The laser will indicate the actual
cutting position. The laser pointer is turned on and off by means of the
switch (Fig.3,Ref.E).
The pointer is aligned with the blade and must not be moved from the
initial position.
- The pointer uses a low-power laser, nevertheless it is
advisable not to look directly at the emitter.

12. MAINTENANCE

12.1 Foreword
Routine maintenance operations can also be performed by non-
specialised personnel provided that all safety standards specifi 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 infi 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 fl 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 fi xing fl ange and
diamond blade. During disassembly, avoid use of tools that could dent
or deform the fl 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 Replacing the drive belt
The machine is equipped with a special long-life pre-tensioned belt. For
replacement, contact an authorised service centre.
12.7 Carriage play adjustment
The carriage slides along the aluminium section by means of rollers;
over time any play will affect cutting precision. To adjust the rollers,
contact an authorised service centre.
13 Repairs
Repairs to the electrical installation must be performed exclusively
by specialised personnel. Use exclusively original IMER spare parts;
modifi cations to parts are strictly prohibited. The special design of the
C 350 iPower ensures that no other maintenance other than that
specifi ed above is required. Ensure that the contacts of the power plug
and plug-switch assembly are effi
immediately
- In the event of activation of the differential circuit breaker,
check the machine and arrange for repairs if necessary exclusively
by specialised personnel.
14 Disposal of refuse
As regards disposal of processing waste, observe all current legislation
in the country of use.
15. 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.
