2.2 AIR INSTALLATION
THE AIR INSTALLATION MUST BE MADE ONLY BY
QUALIFIED PERSONNEL.
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 insuffi cient for certain
tires and substantially reduces tire changer performance.
It is suggested that the shop 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 supply with a rubber
hose (rated for the pressure) with an internal diameter of
no less than 1/2” (12.5 mm).
- The air inlet fi tting is ¼” NPT tapered pipe threads.
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 strongly recommended that an air valve shut-off be
installed between the shop air supply and the tire changer
for routine maintenance and in case of an emergency.
C. Should you install any optional accessories, please
refer to the relevant instructions.
D. Ensure the functional ability of the air lubricator by
ensuring that the glass sight bowl is fi lled with air tool
lubricant.
