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

the motor by bring the control knob back to the center position, as when coming to a com-
plete 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 

 Hoss Jr.

 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  Hoss Jr.

 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 handle  completely backwards.  The motor/brake combi-
nation is now disengaged and the wheelchair will not operate, but will roll freely.

 Caution:

DO  NOT

  ride the 

 Hoss Jr.

 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!

Braking Systems

         The 

 Hoss Jr.'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,
Dynamic, and  Posi-Lock  Electric  Braking.  All braking occurs automatically during wheel-
chair operation.  Each type of braking is described in the following.

1.  Regenerative Braking is activated while driving the  

Hoss Jr.

 down an incline. When

the wheelchair picks up speed  going down the incline, the motor  generates  electricity.   This
electricity is channeled back through the  Hoss Jr. electronic  control  circuits to

 

recharge the

batteries.  This action keeps the wheelchair from picking up excess speed and provides for
smooth  speed  control.
