2.1 ELECTRICAL INSTALLATION
(air-electric models)
BUILDING ELECTRICAL INSTALLATION MUST
BE MADE BY A LICENSED ELECTRICIAN.
Check that the electrical specifications of the power
source are the same of the machine. The machine uses
110v, 60 hz, single phase 20 amp source. Electric
specifications are clearly marked on a label at the rear
of the machine.
FAILURE TO PROVIDE PROPER ELECTRICAL
SUPPLY AND GROUNDING WILL CREATE A
SHOCK HAZARD TO THE OPERATOR.

2.2 BEAD BREAKER INSTALLATION

The side mounted Bead Breaker is shipped from the
factory dismounted for a more compact shipping package.
A. Cut the plastic tie strap which secures the Breaker
Arm to the cabinet pivot.
B. Remove the "C" clip from the top of the pivot pin, slip
the pin out of the hole.
C. Place the Breaker Arm into position and insert the
pivot pin through the top and bottom holes.
D. Replace the "C" clip retainer onto the pivot pin.
E. Locate the spring located at the rear of the pivot mount.
Place the free end of the spring onto the "ear" located on

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 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.
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).

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 filter failure.

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 site bowl is filled with air lubricant.
