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 modification for maximum perfor-
mance.
After ensuring all the above proceed as follows:
A. Connect the machine to the air supply with a rubber hose
(rated for the pressure) with an internal diameter of no less
than 1/2" (12.5mm).
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.
