9. ELECTRICAL CONNECTION
- Ensure that voltage corresponds to machine
dataplate specifications.
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 efficient 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 (ref.Table 4).

Connect the saw plug to the mains and tighten the mechanical
retainer ring with IP67 protection rating.
- The saw is now ready for operation.
11. SAW START-UP
Connect the mains power cable to the plug on the electrical
panel.
RESIDUAL CURRENT CIRCUIT PROTECTION (KIT 230V-P/
N.1169245 - KIT 110V-P/N.1169249):
It is compulsory to power the sawing machine using a differential
switch (230 V; current intensity 30 mA; max. cut-in time 20 sec).
KIT code 1169245 can be supplied (ref. E fig. 2) to be connected on the
supply cable as shown in the diagram (page 13).
When the KIT has been installed, press the green ON button to be able
to start the sawing machine. An orange led will light up (differential
protection on).
RESIDUAL CURRENT CIRCUIT BREAKER TEST:
Press the black key TEST on the RCCB; the switch
disconnects and the orange led turns off.
After performing the TEST, press the ON key again to activate
the RCCB.
- Carry out the RCCB TEST before each machine
start-up.
Then start the saw by means of the switch on the handle (ref.
P fig.6) , comprising two buttons: green for start, red for stop.
The switch is fitted 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 red pushbutton to
shut down the machine and disconnect the plug from the
power mains.
The RCCB is deactivated each time the power supply is
disconnected.
THERMAL CUTOUT PROTECTION:
- 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 by means of the RCCB
switch and the main switch on the handle (ref.P fig. 6).
The machine is protected against short circuits by a
magnetic protection inside the RCCB.
12 . MACHINE USE
Operation
The correct side for the operator is shown in fig. 3 ref X.
Fill the water tank to the maximum level (approx. 42 litres).
Connect the machine to the power mains and start as
described in paragraph 11.
Open the valve (ref.V fig.7) and ensure sufficient flow of
cooling water to the diamond blade.
Cutting
Place the material to be cut on the cutting surface against the
fence at the required angle using a goniometer.
Adjust the height of the cutting head by means of the
handwheel (ref. R fig. 6).
Ensure that the handwheels for angled cuts (ref. L fig. 7) and
tightened fully down.
Start the saw as described in paragraph 11.
Proceed with cutting moving the saw head by means of the
handle.
In the event of blade rotation shutdown due to excessive
force, free the disk by moving it forwards and wait for the
saw to reach normal operating speed before resuming
operation.
Angled cuts
Loosen the handwheels (ref.L fig. 7), set the cutting head at
the required angle, retighten the handwheels, and proceed as
described in the point above.
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.
Press the workpiece by hand onto the cutting surface.
Apply sufficient pressure on the handle to move the cutting
head without blocking the blade.
13. MAINTENANCE
13.1 Premise
Routine maintenance operations can also be performed by
non-specialised personnel provided that all safety standards
specified in the relative sections of this manual are observed
at all times.
13.2 Machine cleaning
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.
Never use compressed air; this could cause infiltration of dust
or residue in enclosed parts.
Ensure that the cooling water nozzles are not obstructed.
Above all the cooling water in the tank must be changed every
day.
Do not use detergents or lubricants.
13.3 Waste disposal
As regards disposal of processing waste observe all current
legislation in the country of use.
13.4 Repairs
Repairs to the electrical installation must be performed
exclusively by specialised personnel. Use exclusively original
IMER spare parts; modifications to parts are strictly prohibited.
The special design of the COMBI 200 VA ensures that no other
maintenance other than as specified above is required.
Ensure that the contacts of the power plug and plug-switch
assembly are efficient. If oxidation is detected, clean
immediately
- In the event of activation of the RCCB, check the
machine and arrange for repairs if necessary exclusively
by specialised personnel.
13.5 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.
