Comfort Adjustments
After becoming familiar with your power chair’s operation,
you may find the need to make some adjustments to increase
your comfort, such as seat height and angle, armrest width,
angle and height, and controller position.
NOTE: If your power chair is equipped with a Synergy
Seat or TRU-Balance® 3 Power Positioning System, refer
to the seat adjustment information contained in separate
manuals. If your power chair is equipped with a contoured
seating system, refer to the following information.
The center of gravity of your power chair was factory set
to a position that meets the needs of the demographic
majority of users. Your Quantum Rehab Provider has
evaluated your power chair and made any necessary
adjustments to suit your specific requirements. Do not
change your seating configuration without first contacting
Quantum Rehab or your Quantum Rehab Provider.
Some power chair components are heavy. You may
need assistance to lift or carry them. Please refer to
the specifications table for specific component weights
before you disassemble the power chair.
Remove the occupant from the power chair before
making any adjustments.
You may need the following to make comfort adjustments:
metric/standard socket set and ratchet
adjustable wrench
metric/standard hex key set
thread lock
Seat Height and Seat Angle Adjustment
If your power chair is not equipped with a transit securement
system, you can change the seat height to one of three
positions by raising the front and rear trapeze bars. If you
raise or lower only one trapeze bar (front or rear), you can
also change the seat base angle (dump).
If your power chair is equipped with a transit securement
system and any adjustment to the seat height or seat
angle is necessary, contact your Quantum Rehab
Provider. These comfort adjustment can only be made
by a Quantum Rehab Provider.
To change the seat height:
1. Turn off the power to the controller.
2. Make sure the power chair is in drive mode.
3. Unplug the controller connector(s) from the power base.
See figure 1.
4. Flip up the seat latch safety. See figure 5.
5. Squeeze the seat latch and release the seat from the
front trapeze bar.
