Dual Manual Freewheel Levers
For your convenience, your power chair is equipped with dual manual freewheel levers. The levers are located on the
inside of the anti-tip wheels. The levers allow you to disengage the drive motors 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 operate the dual manual freewheel levers:
1. Pull both levers upward to disengage the drive motors (freewheel mode). See figure 7.
2. Push both levers downward to engage the drive motors (drive mode). See figure 8.
If a 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.

Active-Trac Suspension
Your power chair is equipped with Active-Trac Suspension (ATS). ATS is a suspension system designed to make
your power chair traverse different types of terrain and obstacles while maintaining smooth operation. With ATS,
the front anti-tip wheels work in conjunction with the motor suspension to help you maneuver over obstacles.
As the front anti-tip wheels come in contact with an obstacle, the front anti-tip wheel assembly is drawn upward.
At the same time, the motors are forced downward. This allows the motors to push the power chair over an
obstacle and limits the possibility of your power chair getting caught 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.
