Electrical Components
The electrical components are located on the front of the power base or on the battery door at the rear of the power
base depending on the power chair electrical system. See figures 6 and 7.
Main Circuit Breaker: The main circuit breaker is a safety feature built into your power chair. When the batteries
and the motors are heavily strained (e.g., from excessive loads), the main circuit breaker trips to prevent damage
to the motors and the electronics. If the circuit trips, allow your power chair to “rest” for approximately one
minute. Next, push in the circuit breaker button, turn on the controller, and continue normal operation. If the main
circuit breaker continues to trip repeatedly, contact your Quantum Rehab Provider.
Controller Connector: This is where the controller connects to the power base. The controller connector is
located at the front or rear of the power base. See figure 6.
Sport-Trac Suspension
Your power chair is equipped with Sport-Trac Suspension (STS). STS is a suspension system designed to make
your power chair traverse different types of terrain and obstacles while maintaining smooth operation. With STS,
the spring-loaded drive wheels move in two directions—up for rolling over obstacles and down when
encountering transitions.
As the drive wheels come in contact with an obstacle, they are drawn upward. At the same time, the rear anti-tip
wheels work in opposition to the drive wheels to eliminate the possibility of the chair losing traction. This creates
a safer, more secure ride.
STS also helps in day-to-day operating conditions. This unique suspension system helps to harness the motors’
torque to make smoother transitions in speed during acceleration or deceleration.
Manual Freewheel Levers
For your convenience, your power chair is equipped with two manual freewheel levers mounted on the motors.
Depending on which motors your power chair is equipped with, you will have one of two possible freewheel
levers. See figures 8, 9, 10, or 11. These levers allow you to disengage the drive motors and maneuver the chair
manually. You can manually push the power chair by the seatback or push the power base itself if the seat is
removed.
WARNING! Do not use the power chair while the drive motors are disengaged! Do not
disengage the drive motors when the power chair is on an incline or decline, as the
unit could roll on its own. Only engage the freewheel mode when on a level surface.
WARNING! It is important to remember that when your power chair is in freewheel
mode, the braking system is disengaged.
To operate the manual freewheel levers:
1. Push the manual freewheel lever down for freewheel mode (drive disengaged). See figure 8 or 10.
2. Pull the manual freewheel lever up for drive mode (drive engaged). See figure 9 or 11.
NOTE: If the lever is difficult to move in either direction, rock your power chair back and forth slightly. The
lever should then move to the desired position.
WARNING! Do not use the freewheel lever handles as tie-down points to secure this product.
