The Power Wheelchair Braking Systems

 

         

          The power wheelchair's brake systems allow for smooth start up  and safe  braking without 
undue jerking.  There are three (3) separate  modes  to  the  braking  system: Regenerative, Dy-
namic, and  Posi-Lock  Electric  Braking.  All braking occurs automatically during wheelchair 
operation if the joystick power is "ON". If the joystick power is turned "OFF", the regenerative 
braking and dynamic braking are not functional. 

WARNING:

 

Always leave the joystick power 

"ON" when parked on or attempting to stop on an incline. Failure to leave the joystick power 
"ON" could result in partial loss of braking and steering control causing potential damage to 
the equipment and/or harm to the rider.

  Each type of braking is described in the following.

 

 

1.  Regenerative Braking is activated while driving the power wheelchair down an 

 

incline. When the wheelchair picks up speed  going down the incline, the motor  

 

generates  electricity. This electricity is channeled back through the power wheelchair 

 

electronic  control  circuits to recharge the batteries.  This action keeps the wheelchair 

 

from picking up excess speed and provides for smooth speed control. 

 

2.  Dynamic  Braking is activated WITHOUT delay when all power is  stopped to the  

 

motor by bringing the control knob back to the center position, as when coming to a  

 

complete stop. This braking works until the Posi-Lock Electric brake is activated.

        3.  Posi-Lock Electric Braking Disk is activated with delay when all power is stopped to  
 

the motor. This electric brake has a short delay and ultimately holds the power 

 

wheelchair  at a complete stop. The wheelchair cannot be moved when this brake is 

 

activated. Dynamic Braking works in conjunction with Posi-Lock Electric Braking 

 

to bring you to a gradual and complete stop.

MOTOR/BRAKE DISENGAGE MECHANISM

          
          The power wheelchair is equipped with one Motor/Brake 
Disengage lever (one for the entire motor). This systems allows 
the wheelchair  to be moved in the event the batteries are run 
low, or there is a malfunction.  To operate the Motor disengage 
mechanism, turn the power off to the wheelchair and push the 
lever  completely backwards.  The motor/brake combination is 
now disengaged and the wheelchair will not operate, but will 
roll freely.

 Caution: 

 

 

DO  NOT

  ride the power wheelchair with Motor/Brake Disengage Mechanism activated 

since there is a 

strong possibility 

an accident with injuries will occur.  Should you experience 

any type of brake system malfunction,  

DO NOT

 ride or sit on the wheelchair. Have the system 

repaired immediately!

SHOULD THE BRAKE DISENGAGE ON A WHEELCHAIR EVER APPEAR TO WORK 
POORLY OR INCORRECTLY,  STOP RIDING IMMEDIATELY AND CONTACT YOUR 
DEALER FOR SERVICE!
