Quantum Dynamo ATS/RevA/Apr04
Manual Freewheel Levers
The 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, causing
injury!
NOTE: You must turn off the power before disengaging the drive motors, otherwise you may get
an error code (nine flashing lights) on the controller. To clear this code, turn off the controller
and place the power chair in drive mode. Then turn on the controller. The error message should
be cleared. If it isnt, contact your Quantum Rehab Specialist.

To engage or disengage the drive motors:
1. Locate the levers on the front of the power base. See figure 8.
2. Push down the manual freewheel levers to engage the drive
motors (drive mode).
3. Pull up the two levers to disengage the drive motors (freewheel
mode).
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.
Limited Active-Trac Suspension
Your power chair is equipped with a limited Active-Trac
Syspension (ATS). See figure 9. ATS is a suspension system
designed to make your power chair traverse different types of
terrain and obstacles while maintaining smooth operation. With
ATS, your front anti-tip wheels work in conjunction with your
motor suspension to help you maneuver over obstacles.
As your front anti-tip wheels come in contact with an obstacle, the front anti-tip wheel assembly is drawn upward. At the
same time, your motors are forced downward. This allows the motors to push your power chair over an obstacle and limits
the possibility of your power chair becoming hung up on the obstacle.
ATS also helps in day-to-day operating conditions. For instance, when you release the joystick, your power chair begins
to slow down. As the chair slows down, the front anti-tip wheels will automatically drop toward the ground. This will
reduce the forward tip that is typically encountered with mid-wheel drive chairs.
