INTRODUCTION
The Americans with Disabilities Act (ADA) of 1990 established the legal requirement for
public facilities to provide access and reasonable accommodations for people with
disabilities. In response to this requirement, the Ascension PROTEGE portable
wheelchair lift provides the means for individuals who cannot negotiate stairs to gain
access to a moderate vertical floor elevation change, such as a stage, riser, or platform.
This portable wheelchair lift has been designed with both the passenger and the facility
in mind. It provides the passenger with safe access to a stage, and gives the facility
maximum flexibility and ease of use. Because it is transportable, the lift can be quickly
set up for use when needed or put into storage when not needed. The lift can be used
at almost any stage or platform up to 42 inches [1060 mm] high.

Important Safety Information
When using the lift, the following basic safety precautions and practices must be
observed:
1. Read and understand all of the information contained in this manual.
2. Do not expose any part of the lift to a direct liquid stream or spray, such as a water
hose. This could create an electrical shock or fire hazard.
3. Do not operate the lift in the presence of combustible or explosive gas or fumes.
The electrical components of the lift could cause ignition of these chemicals.
4. Do not operate the lift if the electrical cord has become frayed or if its outer
insulation has been removed, as this could create an electrical shock or fire hazard.
5. Do not allow any equipment, including the lift itself, to lie across or on the electrical
cord, as this could cause the cord to become damaged, resulting in electrical shock
or fire hazard.
6. Set up the lift for operation only in accordance with the instructions in Section 2 of
this manual. If the lift cannot be set up as described, contact the manufacturer to
determine the correct set up for a particular application.
7. The upper height limit sensor adjustment must be confirmed every time the lift is
relocated. Failure to do so could result in serious injury to the user.
8. Operate the lift only as described in Section 3 of this manual.
9. Use extreme caution when moving the lift on an incline, as the lift weighs
approximately 850 pounds [385 kg].
10. Transport the lift as described in Section 4 of this manual.
11. Use the lift for movement of people only.
12. Use an extension cord only as described in Section 4 of this manual.
13. Always close and lock all access panels and remove all keys before leaving the lift

Operating Manual SECTION 1
PROTEGE 5442P

Description of Operation
Two hydraulic cylinders raise and lower the platform. When the "Up" circuit is
energized, an electric motor operates a hydraulic pump which provides pressurized
hydraulic fluid to the cylinders, causing the cylinder rods to extend and raise the
platform. When the "Down" circuit is energized, a hydraulic valve is shifted so that the
fluid flows in the opposite direction through the hydraulic circuit and the platform is
lowered.
A gate at each end of the lift permits passengers to enter and leave the platform. The
lower landing gate will open only when the platform is lowered all the way. The upper
landing gate can be fully opened only when the platform is at the upper landing. Both
gates are self-closing.
The height limit sensor is located in the left-hand machinery cabinet. This switch halts
the movement of the platform when it reaches the upper landing, and its adjustment
must be confirmed every time the lift is relocated.
The motion of the platform is controlled by any of the three operating switches located
on the right side of the lift. These are constant-pressure type switches, so that when a
switch is released the platform stops. It takes approximately 40 seconds for the
platform to move through its full range of 42 inches. These switches are interlocked so
that while one switch is activated, pressing another switch in the opposite direction will
not cause the lift to stop; the original action will continue.
The lift is equipped with an under-platform safety pan that will halt all motion of the
platform if it encounters an obstruction as it descends. If this occurs, use the hand pump
or setup key to raise the platform and allow for the removal of the obstruction. The
under-platform safety pan completely covers the bottom and side edges of the platform.

Operating Manual SECTION 1

The dock plate is tethered to the bottom of the upper landing gate by a cable that lowers
the dock plate as the gate opens. When the upper landing gate is closed, the dock
plate is raised by its tether.
The unit is equipped with a hand pump that can be used to raise or lower the platform in
an emergency, or when the casters are being put under the platform and power is not
available. The hand pump is located in the right-hand machinery cabinet.
The casters are stored in the left-hand machinery cabinet. They can quickly and easily
be installed underneath the lift so that the lift can be moved to another location. The
hydraulic system is used to raise and lower the platform and base frame when installing
or removing the casters.
The electrical control panel is located inside the right-hand machinery cabinet. This
panel includes the power supply, control system relay, and main power relay. A Ground
Fault Circuit Interrupter (GFCI) and lockable disconnect switch with integrated overload
protection are located on the electrical cord near the wall plug.

SECTION 2
Setup Instructions
1. Prior to operation, position the upper landing end of the lift 1 to 3 inches [25 to 75
mm] from and approximately parallel to the edge of the upper landing (stage). This
space should be flat, level, and free of any debris or obstructions (including the lift’s
power cord).
2. Plug the power cord into a grounded electrical outlet and turn the disconnect switch
to the ON position. Raise the platform at least 12 inches [305 mm]. To do so, turn
the barrel key in the setup switch on the front of the lift and hold an operating switch
‘up’, OR use the manual pump per Section 4, Operating the Lift Without Power.
Certain option packages (incl. universal key switches) require manual operation.
3. Remove all four casters from the platform underside by pulling them straight down.
Place them in the caster storage brackets in the left-hand machinery cabinet
according to their color codes. See Figure 2. The casters must be removed before
the lift can be operated.

4. Use an operating switch to lower the platform to the floor.
5. Enter the platform and use the operating switch located inside the platform to move
the platform upward until it stops.
6. Open the inner access panel on the left-hand machinery cabinet and remove the
height adjustment tool from its storage bracket. Refer to Figure 2 for identification of
the adjustment tool.
7. Use the adjustment tool to remove the magnetic optical reflector from the vertical
guide rail. To do so, place the adjustment tool on the reflector, turn it clockwise a
quarter turn to engage the reflector, and then pull the reflector off the guide rail.
Reserve the reflector in the adjustment tool until Step 11. The reflector is located
near the bottom of the cabinet and is marked by a yellow decal. See Figure 3.
