WARNING! The cantilever seat option is intended for use on a flat, level surface only. Never raise
the seat from its lowest position on an inclined surface. Failure to heed this warning can result in
the power chair tipping over and causing injury.
WARNING! Never raise the seat from its lowest position when operating your power chair on
bumpy or uneven surfaces. Failure to heed this warning can result in the power chair tipping over
and causing injury.
WARNING! Never raise the cantilever seat while your power chair is in freewheel mode.
WARNING! Always fasten the positioning belt when operating the cantilever seat.
Cantilever Seat Operation
You can control the cantilever seat through either a toggle switch mounted to the armrest or through your joystick/controller.
For information on how to raise and lower your cantilever seat through your controller, contact your Quantum Rehab
Specialist.
To operate the cantilever seat:
1. Bring your power chair to a complete stop.
2. Push the toggle switch forward to raise the seat. When you release the toggle, the seat will stop. Once the seat reaches
its highest extension, the lift action stops; you should continue to hear and/or feel the lift motor running. This is because
there is a clutch mechanism that allows the motor to continue running after the lift has reached its limit. This clutch works
at both the top and bottom extensions of the lift.
WARNING! Do not allow the motor to run more than a few seconds after the mechanism reaches
the top or bottom limit.
3. Pull the toggle switch rearward to return the seat to its lowest position. When returning to the lowest position, always
be sure that the mechanism has reached its lowest limit.
Presence Sensing System
The cantilever seat is equipped with a “Presence Sensing System” that enables the electronics to cut power to the seat
whenever there is an obstruction between the seat and the power base. Sensors are located on the bottom of the seat rails
and can detect objects that are placed between the seat rails and the power base. When the cantilever system stops
because of an obstruction, you have to reset the joystick before you can move the seat.
To reset the joystick:
1. Release the joystick to the neutral position.
2. Make sure the obstruction has cleared.
3. Use the joystick to move the seat.
