III. YOUR POWER CHAIR
Dual 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.

Hammer Motor Package
Your power chair may be equipped with two powerful Hammer motors. These are right angle motors capable
of producing one horsepower of peak output each. Follow the suggestions below to help ensure peak motor
performance.
Maintain an even speed when negotiating obstacles. If you encounter a situation where you have stalled the
motors, immediately release the joystick. Adjust the controller to a higher drive profile and attempt to move over
the obstacle. If you still encounter a stall condition, back away from the obstacle, then drive forward, maintaining
momentum as you negotiate over the obstacle.
WARNING! Prevent motor damage! Immediately release the joystick if the motors stall. Failure to
release the joystick within 5 seconds of motor stall may cause the motors to overheat, resulting
in damage to the motors, lack of motor performance, and/or increased motor noise.
To operate the dual manual freewheel levers:
1. Push down both manual freewheel levers for free-
wheel mode (drive motor disengaged). See figure 4.
2. Pull up both manual freewheel levers for drive mode
(drive motor engaged). See figure 5.

controller, place the power chair in drive mode, then
turn on the controller. The error message should be
cleared. If it is not cleared, contact your Quantum
Rehab Provider.
NOTE: The power chair will be significantly easier to
push with the power off.

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.
