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.

Manual Freewheel Levers
Your power chair has a manual freewheel lever on each motor. 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! 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 engage or disengage the drive motors:
1. Locate the lever on top of each motor.
2. Push the two levers inward to engage the drive motors (drive mode). See figure 8.
3. Pull the two levers outward to disengage the drive motors (freewheel mode). See figure 9.
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.
NOTE: The power chair will be significantly easier to push with the power off.
Avoid applying excessive force to the manual freewheel levers.
WARNING! Do not use your foot to operate the manual freewheel levers. Do not stand on the
manual freewheel levers. Applying excessive force to the manual freewheel levers may result in
damage to the freewheel levers, motors, and brakes.
WARNING! Do not use the freewheel lever handles as tie-down points to secure this product.
