Quantum TRU-BALANCE 3, Basic Operation Instructions

10

Do not attempt to lift or move your power chair or 

seating system by any of its removable parts, including 

the armrest(s), front rigging(s), seat cushions, seatback, 

shrouds, or controller. Use only solid, non-removable 

frame components to lift or move your power chair or 

seating system.

Avoid putting all of your weight on the power chair 

armrests and do not use the armrests for weight-bearing 

purposes, such as transfers. Such use may cause the 

power chair to tip, resulting in a fall from the power chair 

and personal injury.

The controller and controller bracket are non-load 

bearing items on your seating system. Do not use the 

controller or controller bracket for weight-bearing 

purposes, such as transfers. Such use may cause 

damage to these components, resulting in a fall from the 

seating system and personal injury.

Flip-Up Armrests
The Flip-up Armrests are designed to “flip up” out of the 
way for easier transfer onto and off of the power chair. The 
armrest height, angle, width, and swing can be adjusted.

NOTE: Changing the armrest height also changes the 
armrest angle. We recommend adjusting the armrest 
height first then adjusting the armrest angle.

To adjust the armrest height:
1.  Ensure armrest is flipped up to at least a 95° angle from 

the seat pan for height adjustment.

2.  Loosen rear screw on rear armrest support joint. 

See 

figure 8.

3.  Make sure on seatback side rail your rear pivot link is 

mounted to proper height relative to back. 

See figure 8.

4.  Ensure the armrest at a 95° angle remains.
5.  Raise or lower the armrest to set armrest to the desired 

height or location mark. 

See figure 8.

6.  Make sure the teeth of the pivot link and the teeth of 

the rear armrest support joint are interlocked before 
tightening rear screw of rear armrest support joint.

7.  Loosen front screw on front armrest support joint.

 See 

figure 8.
