Operation Instructions
2.2 AIR INSTALLATION
THE AIR INSTALLATION MUST BE MADE ONLY BY
QUALIFIED PERSONNEL.
EXCESSIVE AIR PRESSURE CAN SERIOUSLY IN-
JURE PERSONNEL AND DAMAGE THE MACHINE.
Ensure that the line pressure is within the limits required by
the machine. If the pressure exceeds 170 psi (12 bar) it is
mandatory to install a pressure regulator before the air inlet
of the machine.
If the air pressure is lower than the minimum required of
110 psi (8 bar) the clamping power of the turntable and the
bead breaker power may be insuffi cient for certain tires and
substantially reduces tire changer performance.
It is suggested that the air supply be equipped with a water
separator/dryer type modifi cation for maximum performance.
After ensuring all the above proceed as follows:
A. Connect the machine to the air sup-
ply with a rubber hose (rated for the
pressure) with an internal diameter of
no less than 1/2” (12.5mm).
WARNING!
BEFORE CONNECTING THE MACHINE TO THE AIR
SUPPLY BE SURE ALL PERSONNEL ARE CLEAR
OF THE MACHINE AND NO ITEMS ARE LEFT ON
THE TURNTABLE.
B. It is recommended that an air valve shut-off be installed
between the shop air supply and the tire changer in case of
air line or fi lter failure.
C. Should you install any optional accessories, please refer
to the relevant instructions.
D. Ensure the functional ability of the air lubricator by ensur-
ing that the glass site bowl is fi lled with air lubricant.
