2.3 AIR INSTALLATION

WARNING!
THE AIR INSTALLATION MUST BE MADE ONLY BY
LICENSED PERSONNEL.
WARNING!
EXCESSIVE AIR PRESSURE CAN SERIOUSLY INJURE
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 insufficient 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
performance.
