18 HOSS Jr. - Owner's Manual
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!
The Hoss Jr. 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.
