AYOUT
1) Layout the service bay according to the architect’s
plans or owners instructions
(see Fig. 1
).
Failure
to install in this orientation can result in
personal and property damage.
Be certain that
the proper conditions exist, see page 3.
NOTE: The correct orientation of the platforms
(DX & SX) is critical for proper layout of the lift.
The SX pad contains the longer air line which
is located under the front pivoting ramp.
2) See
Fig. 2
for control console location.
Relocating the control console further away than
the standard distance will require the installer to
provide suitable hydraulic hoses and air line.
Additional hose covers will also be needed if
installing lift in surface mount configuration.
Hydraulic hoses should be 1/4" minimum ID with
a minimum working pressure of 3000 psi and a
minimum burst pressure of 12,000 psi with #6 JIC
Swivel Female fittings. The air line for the locks
requires Ø6mm OD x 1mm wall poly tubing.
NOTE: Extend both hydraulic hoses the same
length and do not extend the hoses more than
21 feet [252 in].
3) Relocating the control console from DX to SX
side will require moving the green hose blocks at
the base of the unit under the ramp to direct the
hoses to the new side.
4) If the platform spacing is more than 27” wide
such as for wide electric vehicles, an extension
for the hydraulic hose and airline may be required
to locate the control box in desire location. See
Step #2 for hose and airline specs. For Wide
Electric Vehicles, please refer to DX77-SUP-T
provided with the optional hose cover (10354-4).
