– MAINTENANCE
7.1 GENERAL WARNINGS
Unauthorized personnel may not carry out maintenance work.
•
Regular maintenance as described in the manual is essential for correct operation and long
lifetime of the tire changer.
•
If maintenance is not carried out regularly, the operation and reliability of the machine may be
compromised, thus placing the operator and anyone else in the vicinity at risk.
Disconnect the electric and pneumatic supplies before carrying out
any maintenance work. It is necessary to operate the bead breaker without load
3-4
times in order to release the air pressure from the circuit.
•
Defective parts must be replaced exclusively by authorized personnel using the
manufacturer’s original parts.
•
Removing or tampering with safety devices (pressure limiting and regulating valves) is

In particular the Manufacturer shall not be held responsible for
complaints deriving from the use of spare parts made by other manufacturers or
for damage caused by tampering or removal of safety systems.

•
Check that a drop of oil is injected into the reservoir F very 3-4 times the pedal U is
pressed down. If not, regulate using the screw D (fig. 14)
