On delivery, the machine is pre-set to operate at a volt-
age of 400 V. For any other type of power supply, ask
the manufacturer at the time of purchase: a machine
functioning under the required voltage conditions will
be prepared.
FIT A TYPE-APPROVED (AS RE-
PORTED BEFORE) PLUG TO THE
MACHINE CABLE (THE GROUND
WIRE IS YELLOW/GREEN AND
MUST NEVER BE CONNECTED TO
THE PHASE LEADS). MAKE SURE
THAT THE ELECTRICAL SYSTEM
IS COMPATIBLE WITH THE RATED
POWER ABSORPTION SPECIFIED
IN THIS MANUAL AND APT TO
ENSURE THAT VOLTAGE DROP
UNDER FULL LOAD WILL NOT
EXCEED 4% OF RATED VOLTAGE
(10% UPON START-UP).
IN CASE OF A CHANCE SUPPLY
FAILURE, AND/OR BEFORE ANY
POWER SUPPLY CONNECTIONS,
MOVE THE PEDALS TO THE NEU-
TRAL POSITION.
10.1 Oil check on oil-pressure power unit
THE OIL-PRESSURE POWER UNIT
IS DELIVERED WITHOUT HY-
DRAULIC OIL, THEREFORE MAKE
SURE THE TANK PROVIDED IS
FILLED WITH OIL WITH VISCOS-
ITY DEGREE APPROPRIATE TO
THE AVERAGE TEMPERATURES
IN THE INSTALLATION COUNTRY
AND IN PARTICULAR:
- VISCOSITY 32 (FOR COUNTRIES
WITH ROOM TEMPERATURE
FROM 0 TO 30 DEGREES);
- VISCOSITY 46 (FOR COUNTRIES
WITH ROOM TEMPERATURE
ABOVE 30 DEGREES).
10.2 Check of motor rotation direction
Once the last electrical connection has been termi-
nated, power the machine with the main switch.
Make sure the motor of the hydraulic power unit ro-
tates in the direction indicated by the arrow (
Fig.
_
8A,
8B, 8C and 8D ref.
_
B
) visible on the electric motor
cap.
If rotation should occur in the opposite direction, the
machine must be immediately stopped and phase in-
version must be executed inside the plug connection
in order to reset the correct rotation direction.
FAILURE TO OBSERVE THE ABOVE
INSTRUCTIONS WILL IMMEDIATE-
LY INVALIDATE THE WARRANTY.
10.3 Electrical checks
BEFORE STARTING UP THE TYRE-
CHANGER, BE SURE TO BECOME
FAMILIAR WITH THE LOCATION
AND OPERATION OF ALL CON-
TROLS AND CHECK THEIR PROP-
ER OPERATION (SEE PAR. “CON-
TROLS”).
CARRY OUT A DAILY CHECK OF
MAINTAINED-TYPE CONTROLS
CORRECT FUNCTIONING, BEFORE
STARTING MACHINE OPERATION.
Once the plug/socket connection has been made, turn
on the machine using the master switch (
Fig.
_
8A, 8B,
8C and 8D ref. A
).
ONCE THE ASSEMBLY OPERATIONS HAVE
BEEN ENDED, CHECK ALL MACHINE FUNC-
TIONS.
