those included in this specification. IMER INTERNATIONAL
accepts no responsibility for loss or damage resulting from
improper use of the machine.
4 CUTTING CAPACITY (Disc diameter 750 mm)
• Maximum cutting capacity in one pass = 300 mm
• Maximum height of the piece to be cut = 430 mm
• Minimum width of the piece to be cut = 50 mm
• Maximum cutting length with disc lowered = 500 mm
• Maximum cutting length with disc descent from above = 560
mm
5 WARNING
Do not load the machine with pieces of excessive weight (max
Kg 40).
• Pay attention to the stability of the machine: it must be
installed on a stable base with a maximum inclination of 5°
(Fig. 2).
• The machine is equipped with a brake on the front swivel
wheels. Before starting the cutting operations, lock the wheels
with the brake.
• Pay attention to the stability of the pieces before, during and
after cutting: the pieces must not protrude out of the working
surface in any case.
• Avoid spilling residual liquids from cutting by using suitable
containers.
6 SAFETY MEASURES
The IMER saw is designed to operate on construction sites
and is not equipped with its own lighting; the work site must be
well illuminated (min. 500 lux).
- Never use the saw in environments subject to the
risk of explosions and/or fire.
1. The IMER sawing machine will only run if all the safety
devices are in place and in perfect condition.
2. Do not use improvised and/or defective power supply
lines.
3. The connection lines on the site must be laid in such a
way that they cannot be damaged. Never stand the saw on
the power supply cable.
4. The plug/socket connections must be protected from
water. Use only connectors equipped with protection
against water jets (IP67).
5. Repairs to the electrical installations must only be
carried out by specialised personnel. Do not make any
adjustments or carry out any maintenance work while the
machine is powered up or running.
-To stop the saw from working, use solely the specific
switch (ref. 7, Fig. 1).
7 ELECTRICAL SAFETY
The IMER sawing machine complies with current legislation
and in particular it is equipped with:
• System for preventing unwanted start-up on return of power
after a power failure.
• Protection against short circuits.
• Thermal cut-outs protecting the motor.

8 . TRANSPORTABILITY
- Before removing the sawing machine, lock the
trolley by acting on the stopper (ref. 4 -Fig. 2).
To lift the machine, use a three-boom tie rod (ref. 1, Fig. 2),
engaging the hooks in the special connections (ref. 3, fig.4). To
carry the machine with a fork-lift truck, engage the forks in the
special seats (ref. 2, Fig. 2).
Being the machine mounted on wheels, it can be moved
manually on level surfaces in the following way:
1. make sure the front wheel brakes are released.
2. make sure that the workpiece trolley is blocked by means of
the special ratchet (ref. 4,Fig. 2).
3. acting on the handle of the workpiece trolley, tow the
machine manually; the pivoting front wheels facilitate the
movement even if not straight.
9 INSTALLATION
1. Position the machine on a horizontal plane in a stable way.
2. Lock the front wheels with the brakes.
3. Unlock the trolley from the stop that fastens it to the head
(ref. 4, Fig. 2).
10 ELECTRICAL MAINS CONNECTION
- Ensure that voltage corresponds to machine
dataplate specifications.
The power supply line must be equipped with current overload
protection (e.g. thermal-magnetic cutout) and protection
against indirect contact (e.g. residual current circuit breaker).
The electrical power distribution board at the construction site
must conform to the requirements of EN 60439-4.
The electric cable wire size must take into account the
operating currents and length of the line to avoid excessive
voltage drops (Tab 5-recommended values).
Model
Masonry 750 Plus
Check the integrity of the insulation and protective conductor
of the electrical supply.
Connect the machine plug to the electrical power supply and
tighten the mechanical retainer ring with IP67 protection rating.
The machine is now ready for operation.
11 COMMISSIONING THE MACHINE
Before connecting the machine to the electric mains:
1. Check that the tank contains a sufficient amount of cooling
water (minimum 60 l, maximum 90 l).
