2.1
Training of personnel
The machine may be operated only by suitably
trained and authorized personnel.
Given the complexity of the operations necessary to ma-
nage the machine and to carry out the operations safely
and efficiently, the personnel must be trained in such
a way that they learn all the information necessary to
operate the machine as intended by the manufacturer.
A CAREFUL READING OF THIS
INSTRUCTION MANUAL FOR USE
AND MAINTENANCE AND A SHORT
PERIOD OF TRAINING WITH SKIL-
LED PERSONNEL CAN BE AN
ENOUGH PREVENTIVE PREPARA-
TION.
3.0 SAFETY DEVICES
PERIODICALLY, AT LEAST MONTH-
LY, CHECK THE INTEGRITY AND
THE FUNCTIONALITY OF THE
SAFETY AND PROTECTION DE-
VICES ON THE MACHINE.
All the machines are equipped with:
• “man-operated” controls (immediate stop of opera-
tion when the control is released).
• Controls logic disposition
To prevent the operator from making dangerous
mistakes.
• thermal magnetic switch on the supply line of the
oil-pressure power unit motor: avoids the motor
overheating in case of intensive use.

CIRCUIT PRESSURE LIMITER IS
PERMITTED
• controlled check valves on:
- opening of clamping unit jaws,
- mandrel arm lifting,
- tool holder arm tilting (only for versions foreseeing
such operation).
These valves have been fit in order to avoid unex-
pected movements of the jaws, tool or mandrel arm
(and, as a consequence, the wheel fall) caused by
accidental oil drippings.
• Fuses on the electric supply line of the clamping
unit motor,
• Automatic power supply disconnection with the
opening of the electric panel.
• Mandrel self-braking motor (only for GG40256.15,
GG40256T.15, GG40256A.15, GG40256D.15,
GG40256TD.15, GG60360.15, GG60360T.15,
GG60360A.15, GG60360D.15 and GG60360TD.15).
• Mandrel self-braking motor (on demand only

•
Motor protection devices
(only for GG40256D.15,
GG40256TD.15, GG60360D.15 and GG60360TD.15)
The new “Invemotor” unit is equipped with electronic
protection devices. They stop the motor if working
defected conditions appear to avoid that the motor
itself can be damaged and that the operator safety
can be compromised (overvoltage, undervoltage,
overload, overtemperature).

table”.
