III. YOUR POWER CHAIR
Active-Trac System
Your power chair is equipped with an Active-Trac System (ATS). See figure 10. 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 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 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 center-wheel drive chairs.

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.
