Main Circuit Breaker (located on rear battery box): 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 Specialist.
Controller Power Module: The controller power module enables the controller to communicate with the batteries and
the motors.
Motor Connectors: This is where the motors connect to the controller power module.
Manual Freewheel Levers
Your power chair has a manual freewheel lever on each motor. See figure 6. Manual freewheel levers enable you to
disengage the drive motors from the gearboxes and maneuver the chair manually.
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, as the unit could roll on its own, causing
injury!
To engage or disengage the drive motors:
1. Locate the lever on top of each motor.
2. Pull the two levers upward to engage the drive motors. See figure 8.
3. Push the two levers downward to disengage the drive motors. See figure 9.
If a lever is difficult to move in either direction, slightly rock the power chair back and forth. The lever should then move
to the desired position.
WARNING! It is important to remember that when your power chair is in freewheel mode, the
braking system is disengaged.
