Bariatric Wheelchair Mover—Operating Manual
5
Introduction
The Bariatric Wheelchair Mover is a battery operated mobile unit designed to
power-assist patient wheelchairs, while helping to reduce the risk of back/
shoulder strain for the operator―caused by manually pushing or pulling
wheelchairs.
The Bariatric Wheelchair Mover includes the latest developments in DC motors with
automatic electromagnetic park braking, as well as a high capacity programmable
controller.
Features include quiet operation, ease of handling, high manoeuvrability, low
maintenance, and the ability to handle loads up to 300 kg on a 6 degree gradient.
The Bariatric Wheelchair Mover slows and brakes automatically when the twist grip
isreleased.
Under typical operation, the Bariatric Wheelchair Mover battery capacity should be
adequate for a day’s operation. Overnight charging is recommended, and in high-use
situations additional ‘top-up’ charging is advised. It is recommended to use the charger
supplied with the Bariatric Wheelchair Mover when charging the sealed maintenance-
free batteries. This charger is especially designed to set the charge rate, prevent
gassing, and automatically cut switch to ‘trickle charge’ when charging is complete.
All bearings are pre-lubricated and sealed and should not require attention in normal
use. Regular maintenance requirements on the vehicle are therefore minimal and are
covered in this manual.
As with any machinery, safety considerations demand that the Bariatric Wheelchair
Mover be handled with caution, and only operated by trained and authorised personnel.
In addition, the wheelchair must be securely locked to the Bariatric Wheelchair Mover.
The Bariatric Wheelchair Mover must only be operated by trained and
authorised personnel.

Controls
Key switch
The key switch must be turned clockwise to switch the Bariatric Wheelchair Mover on.
When on, the LED status indicator will be illuminated. It is important to note that the unit
should be switched o and the key removed, whenever it is not in use. This eliminates
the risk of unauthorised movement and also prevents an unnecessary use of battery
power.
Emergency back-o bar
When the Emergency back-o bar is activated (depressed) while in motion, the Bariatric
Wheelchair Mover will behave in one of two ways.
1. In reverse (towards the operator), the Bariatric Wheelchair Mover will stop and then
move away from the operator for a short distance.
2. In the forward direction, the Bariatric Wheelchair Mover will reduce to a slow speed.
Any accessories installed that prevent the safe operation of the
emergency back-o bar may create a crush hazard for the user.
Throttle
The throttle provides variable speed control. Releasing the throttle stops the unit.
An automatic park brake is applied after a short delay after the grip has returned to its
neutral position. Under no load, the park brake will maintain the Bariatric Wheelchair
Mover in a stationary position. Under load, the brake may not be capable of holding the
system stationary, particularly on a sloping surface.
Battery level indicator
The battery level indicator indicates the amount of charge
left in the batteries. When it appears to be running low,
return the Bariatric Wheelchair Mover to the closest
charging station to charge the batteries.
Speed selector
Select a speed that you are comfortable using. The
speed can be changed whilst driving. It is advisable that
the operator select a slow speed when approaching a
wheelchair to hitch; entering a con ned area; on a slippery
or slightly sloped  oor surface; turning, or reversing.

Brakes
Two braking systems operate in the Bariatric Wheelchair Mover. Firstly, when the throttle
is released the Bariatric Wheelchair Mover is slowed electronically with dynamic braking
until the Bariatric Wheelchair Mover and the accompanying load stops. In addition,
after a short delay an automatic electromagnetic brake is activated to stop the Bariatric
Wheelchair Mover.
Park brakes release
In the case where the unit cannot be turned on due to a at battery, use the park brake
release switch located on the column. Use this key switch to override the motor park
brake, the machine can now be manually pushed to a dierent location. Remove the
key from the park brake release and immediately place the machine on charge when
unit is at the charging station. Conrm the charger has begun to charge the batteries,
leave on charge for a minimum of eight hours. If the machine is still not working call an
Electrodrive service agent.
Using the Bariatric Wheelchair Mover
Safety check
Before using the Bariatric Wheelchair Mover, the operator should complete the following
safety check.
1. The charger is disconnected from the Bariatric Wheelchair Mover.
2. The emergency back-o works.
3. The battery condition indicator shows adequate charge.
4. The braking system is in operation, so that when stopped, the unit cannot be
manually moved, and that the unit slowly moves when the throttle is applied.
5. The Bariatric Wheelchair Mover hitch is not damaged and securely latches onto the
wheelchair frame.
Safe operation
1. The unit, when attached with a wheelchair, may present a hazard to other sta
and moving hospital equipment during an emergency. Setting the proper speed is
advised in such cases.
2. Even though the electromagnetic or other interference of the Bariatric Wheelchair
Mover is not signicant, it may still have an impact on some high accuracy hospital
equipment. It is advised that you do not park or keep the Bariatric Wheelchair Mover
too close to this kind of equipment when they are in use.
3. Always begin driving the Bariatric Wheelchair Mover on SLOW speed to ensure you
maintain control. The Bariatric Wheelchair Mover has an intuitive control system,
so it becomes easier to use the more you use it. Select a speed that is suited to
the competency of the operator. If unsure, start with SLOW speed then adjust up
accordingly.

Hitching and unhitching to a wheelchair
The Bariatric Wheelchair Mover has a gripper hitch for hitching onto wheelchairs.
Suitable for both standard and bariatric sized wheelchairs, it has a maximum range of
700 mm. This is the widest hitch point for chairs when the hitch arms are fully extended.
(See page 10 for the maximum and minimum hitch range.)
Gripper hitch
The standard gripper hitch suits wheelchair frames up
to 40 mm thickness.
Hitching to a wheelchair using the gripper hitches
1. Ensure the wheelchair is on a  at surface.

Appendix 3: Hitch release instructions
The powered hitch function of the Bariatric Wheelchair Mover has built-in safety
controls to limit the output force of the hitch. When this force is exceeded, the
hitch will stop.
1. In the event of the hitch stopping unexpectedly, press the ‘unlock’ button on the
hitch controls. This resets the safety circuit, and allows the hitch to function normally.
2. If, for some reason, the hitch is overloaded in its extreme ‘unlock’ position, there is
an alternative method of ‘driving’ the hitch out of a bind. This will only work if the
hitch is in its unlock position. Whilst holding the hitch ‘unlock’ button on the controls,
press the button simultaneously. This will momentarily override the safety circuit to
get the hitch working in its normal range.
Please note: These instructions should only be carried out by a qualied
maintenance technician. If there is any uncertainty, please contact your local
Electrodrive Authorised Service Agent for further advice.
To avoid the hitch being unnecessarily overloaded, please avoid locking the
wheelchair into the hitch.
