Installation Procedures
INSTALLATION PROCEDURES

Figure 5-2
Figure 5-3
Figure 5-4
Figure 5-5
1. Position rail mounting legs on steps. The number of
legs and spacing will be determined by the overall length
and number of pieces of rail. [Figure 5-1]
2. Set the lower section of rail into the mounting legs.
The clamps t into a small channel on the bottom of the rail.
DO NOT fully tighten the clamps at this time. [Figure 5-2]
3. If your lift has multiple rail sections, splice them
together using the supplied splice bars and screws. The
alignment pins will come pre-installed in one of the rail
sections. [Figure 5-3]
Before sliding rail sections together be sure to plug together
the charge wires running inside the rail. After tightening
the splice bar screws slide down the sections of gear rack to
avoid gaps.
4. Position the rail and mounting legs on the stairs until
you obtain the desired dimension from the nose of the
steps to the underside of the rail. This dimension is noted on
your specic installation drawing. [Figure 5-4]
The bottom end of the rail should be no more than ½” o
the oor; a short leg secures the bottom. After ensuring the
rail is in the proper location, anchor the legs with the four
#14 wood lags provided with each leg.
The top end of the rail will typically stop short of the top
landing and never needs to extend beyond. [Figure 5-5]
NOTE: If installing unit with free standing posts,
refer to page 11-13 before proceeding with these
install procedures..
NOTE: .If your lift was ordered with the rail
pre-cut to length, a drawing for your specic
installation will detail the leg locations.

Installation Procedures
5. Mark the location for the upper guide rail. Measure from
the leg base plate up the wall 36.25” (as indicated by the red
vertical line). Measure in the center of the leg and use a 3 or 4’
level to ensure that the leg is plumb vertically. [Figure 6-1]
6. Measure at least one more leg. Then mark a straight line
between these measurements. If needed, a chalk line can be
lled with talcum powder so there is no risk of discoloring the
wall with standard chalk or pencil line. This line is where the
upper guide rail mounting brackets will be anchored.
[Figure 6-2]
7. Lag the upper guide rail brackets into a wall stud and
space evenly. The upper guide rail brackets do not need to
be directly above the track mounting legs. Put one as close to
each end of the rail as possible.
The guide rail will be longer than needed to allow the joint
splice to be placed directly on one of the mounting brackets.
The joint will have one alignment pin and a splice bar. The
bracket attachment bolt will tighten into the splice bar and
the remaining three set screws are tightened into the splice
bar. [Figure 6-3]
8. Secure the remaining guide rail mounting brackets to
the rail with the threaded bars inside the rail channel. The
bottom end of the guide rail should extend at least as far as
the bottom end of the rail. [Figure 6-4]

Installation Procedures
9. Slide the chassis onto the top of the rail until
it engages the gear rack. Cut the plastic cable tie
on the mail power breaker (ON/OFF) switch. Turn
the main power breaker on; the lift will emit a
long beep.
Run the lift down near the bottom of the rail
using the install switch (black rocker) on top of
the chassis. When you have the lift in the proper
location turn o the main power breaker.
[Figure 7-1]
10. Install the platform mount onto the chassis
by aligning the two large holes on the end of the
slots with the two large Allen-headed cap bolts
protruding from the side of the chassis. For the
bottom slot, use the one on the downhill side of
the mount. [Figure 7-2] Ensure that the bolt heads
are fully seated in the top of the slots, level the
mount and tighten securely. Tighten the two
more cap bolts on the back side of the chassis as
well.
11. Install the Upper Guide Roller on the back
side of the platform mount. Align the two wheels
with the guide rail and secure with a bolt, nut and
washer through the vertical slot in the platform
mount. [Figure 7-3]
Route the wire harness from the bottom end of
the chassis, up under the platform mount and up
to the mating connectors. Plug the connectors
into each other.
12. Secure cable with wire ties through hole in
platform support. [Figure 7-4]

14. If necessary, loosen leveling bolts on the back side of
the platform. Loosen the jam nut on each and turn the bolts
in or out to position the platform. [Figure 8-2]
When empty, the edge farthest away from the chassis
should be slightly (1/2” – 3/4”) higher to compensate for the
deection when fully loaded with a passenger and chair.
15. Plug the harness on the shroud into the harness at
the top of the platform mount. Route the two ramp cables
through the two slots on either side of the shroud then secure
the shroud with the four screws on the sides. [Figure 8-1]

16. If equipped with a 90° ramp, insert the corner rod
through the gray slide block on the underside of the ramp
and attach the ramp to the hinge with three (3) Phillips head
screws and nuts. [Figure 9-1]
17. Insert the upper limit cam into the slot in the rail at
the top and tighten the set screw, this will need to be adjusted
later to stop the lift in the proper location. [Figure 9-2]
Insert the rest of the gear rack into the top of the rail. The gear
rack should be even with the end of the rail and the last piece
may need to be cut o. Install the end plate using the four
Torx head screws and Torx driver (provided).
18. Install the rack compression screw into the end plate
to pre-load the gear rack. Install the Hand Rail end plates into
each end of the Hand Rail. [Figure 9-3]

Installation Procedures
19. Plug in the power supply. The top and bottom of
the rail each have a short wire and plug coming from
the rail end. Plug the power supply into one of these
plugs and plug the other end of the power supply into
a wall outlet. You may use whichever end is a more
convenient location to a wall outlet. [Figure 10-1]
20. Turn on the main power breaker on the chassis.
The status LED indicator will cycle from RED to AMBER
to GREEN to OFF, and then the lift will emit a beep. The
indicator should then return to GREEN, indicating the
lift is now ready to run.
If the indicator does not return to GREEN, check the
following:
• AMBER: Indicates an obstruction. Five
obstruction sensors include: uphill chassis,
downhill chassis, uphill ramp, downhill ramp, and
platform safety pan. Check them all to ensure that
one (or more) is not triggered and check all these
wiring connections.
• RED: Indicates a fault or double obstruction. If
two or more obstruction sensors are triggered
at the same time the lift will disable itself. Turn
the main power breaker o, wait a couple of
seconds and then turn the breaker back on.
If the lift is on the nal limit it is also treated
as a fault and the lift will have to be hand
cranked o the limit. To do this, run the lift up
to the top landing until the lift stops. When
the lift stops, the ramp motor will turn on
to lower the ramp. If you release the rocker
switch the ramp will stop; continue holding
the rocker switch until the ramp stops on its
own. It may be necessary to slide the upper
limit cam down to get the lift to stop at the
proper place in relation to the landing.
