IMPORTANT
A filter/regulator/lubricator must be installed
on air supply at lift. Failure to do so will void the warranty.
Note: Cut air line tubing with sharp blade to length as
required. Tubing must be cut square with no burrs. To
assemble air line tubing into fitting, use firm, manual
pressure to push tubing into fitting until it bottoms, Fig.
25. If removal of the air line tubing from the fitting is ever
required, hold Push Sleeve in (against fitting) and, at the
same time, pull out on tubing.
A. Lift should be at full height and lowered on latches.
B. Run 3/8" air line from existing facility main air supply to
the FRL. Run 3/8" air line from FLR to reducing tee, Fig.
26.
C. Connect reducing tee to air valve, Fig. 26.
D. Attach air valve to air valve bracket (or 3Ø Push Button
Control Bracket when used), Fig. 26.
E. Air Valve Bracket (when used):
Remove motor warnings decal from motor cover.
Remove motor cover screws. Place air valve bracket
on top of motor cover so that the raise switch protrudes
through the hole in the air valve bracket. Mount
air valve bracket and motor cover with the existing
single phase (4) M5 x 15 PHMS motor cover screws or
supplied (4) M5 x 50 PHMS for three phase, Fig. 26a.

Note: Some test fluid may be spilled from the cylinder
breather vent during bleeding of the system.
21. Assemble ramp/chocks and wheel stops to runways
Note: For drive-thru applications, ramp chocks will go on
both ends of runways.

Attach enclosed NP280 decal (ACTUATE TO RELEASE
LATCHES) on bracket. Run 1/4" air line from air valve
to the slot in the fixed runway. Cut air line and attach
to Tee in front yoke, Fig. 27. This air line is for locking
latches.

adding fluid. Raise and lower lift six times. The cylinder
is self-bleeding. After bleeding system, fluid level in
power unit reservoir may be down. Add more ATF or
ISO32 hydraulic oil, if necessary, following instructions
in Step 16. To pressure test, run lift to full rise and run
motor for approximately 5 seconds. Stop and check
all fittings and hose connections. Tighten or reseal if
required. Lower lift. If fill/breather cap, Fig. 22, is lost or
broken, order replacement.
