Pneumatic installation
THE AIR INSTALLATION MUST BE PERFORMED
ONLY BY LICENSED PERSONNEL.
The machine requires an air pressure of 8 to 12 bar (110-
170 psi), as marked on the plate of the machine and on a
sticker attached to the cabinet next to the air inlet.
Ensure that the line pressure is within the limits required
by the machine.
If the air pressure is lower than the minimum required of 8
bar (110psi) the clamping power of the turntable and the
bead breaker power may be insufficient for certain tIres.
If the air pressure exceeds 12 bar (170 psi) it is mandatory
to install a pressure regulator before the air inlet of the
machine (on request #4002916).
It is suggested that the air supply be equipped with a water
separator to reduce the amount of water at the air inlet.
BEFORE CONNECTING THE MACHINE TO THE AIR
SUPPLY BE SURE THAT NOTHING IS LEFT ON THE
TURNTABLE AREA (TOOLS,ETC).
After ensuring all the above proceed as follows:
•
Connect the rubber hose provided to the inflation
gauge and to the air bloc as shown in Fig.iii-5.
•
To install any accessory on request follow the
instructions enclosed with it.
•
Connect the machine to the air supply (max.
pressure of 12 bar - 170 psi) with a rubber hose
(rated for the pressure) with an inside diameter of 6
mm (1/4”) (
Fig. iii-5 ).
•
In case of installation of an air-filter and lubricator,
check correct functioning.
iv Testing procedures
Motor rotation check
Press down the first pedal on the right : the turntable
should rotate clock wise. In case the turntable should
rotate counter-clockwise, do not use the tire changer and
call the authorized distributor for assistance.
ANY DAMAGE CAUSED BY NON APPLICATION
OF THE ABOVE INSTRUCTIONS SHALL NOT BE
DEBITED TO THE MANUFACTURER AND SHALL
VOID THE WARRANTY.
Pneumatic hose connection check
When first setting the machine into operation, check
hose connections and unions for leakage.
v Instructing the operator
(Following applies only if a unit is installed by a service
Technician)
•
Show the operator how to switch the unit on and off.
