ELECTRICAL REQUIREMENTS
For lift installation and operation it is necessary to
have a dedicated circuit with circuit breaker or time
delay fuse. Refer to wiring diagram for circuit sizing.
AIR REQUIREMENTS
This lift is equipped with an air operated lock release
system. The air supplied to the lift must be clean,
dry, lubricated, and regulated to 90-120 psi, FRL
(Filter/Regulator/Lubricator). The FRL must be
within 30 feet of lift. Failure to provide clean, dry,
lubricated, and pressure regulated air will void

ARM INSTALLATION
28) Lubricate the arm pin or carriage arm pin hole
with “anti-seize” and install the arms. Insure that
the arm restraint gears engage and disengage
properly. Arm restraints should disengage when
lift is fully lowered (Fig. 15).
29) Extend the footpad to both extents and apply
“anti-seize” to the retaining ring.

25) On the Power Column, attach the 1/8” air line
from the lock release air cylinder to the push-lock
tee fitting. Run another section of 1/8” air line
from the button valve to the tee (Fig. 14).
26) Connect the rest of the 1/8” air line to the top of
the tee and run it up the column attaching it to
the hydraulic line using wire ties (Fig. 14). Fig. 15-Arm Installation
30) Make sure all the arm bolts are tight using a 3/8”
