13.0 ROUTINE MAINTENANCE
BEFORE CARRYING OUT ANY
ROUTINE MAINTENANCE OR AD-
JUSTMENT PROCEDURE, DISCON-
NECT THE MACHINE FROM THE
ELECTRICITY SUPPLY USING THE
SOCKET/PLUG COMBINATION AND
CHECK THAT ALL MOBILE PARTS
ARE AT A STANDSTILL.
BEFORE EXECUTING ANY MAIN-
TENANCE OPERATION, MAKE
SURE THERE ARE NO WHEELS
LOCKED ONTO THE MANDREL.
BEFORE REMOVING HYDRAULIC
CIRCUIT UNIONS OR PIPES, MAKE
SURE THAT THERE ARE NO PRES-
SURISED FLUIDS PRESENT. PRES-
SURISED OIL SPILLS MAY CAUSE
SERIOUS WOUNDS OR INJURIES.
BEFORE CARRYING OUT ANY
MAINTENANCE WORK ON THE HY-
DRAULIC CIRCUIT, SET THE MA-
CHINE IN THE REST CONDITION.
To guarantee the efficiency and correct functioning
of the machine, it is essential to carry out daily or
weekly cleaning and weekly routine maintenance, as
described below.
Cleaning and routine maintenance must be conducted
by authorized personnel and according to the instruc-
tions given below.
• Disconnect the mains power supply before starting
any cleaning or routine maintenance operations.
• Remove deposits of tyre powder and other waste
materials with a vacuum cleaner.
•
DO NOT BLOW IT WITH COMPRESSED AIR.
• Periodically (preferably once a month) make a
complete check on the controls, ensuring that they
provide the specified actions.
• Every 100 working hours lubricate the tool carriage
sliding guides.
• Periodically (preferably once a month), grease all
moving parts of the machine (see

• Check periodically the oil level of the oil-pressure unit
and, in case, carry out the filling up with hydraulic
oil having a viscosity degree suitable for the average
temperatures of the country where the machine is
installed 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).
At least once a year it is advisable to proceed anyway
to the complete replacement of the hydraulic oil of
the hydraulic unit itself.
CARRY OUT THIS CONTROL WIT
THE MACHINE COMPLETELY
CLOSED (WITH HYDRAULIC PIS-
TONS IN).
• Periodically (about every 100 hours), check the oil
level of the reduction gear and eventually reset the
level.
• Check operation of the safety devices every week.
• Periodically (every 50 working hours approximately),
carry out the (inner and outer) guides of the tool
carriage.
