MANUAL FREEWHEEL LEVERS
Your power chair is equipped with two manual freewheel levers. See
figure 8. These levers allow you to disengage the drive motors and
maneuver the chair manually. This is called freewheel mode.
WARNING! Do not use your Quantum Dynamo ATS while
the drive motors are disengaged unless you are in the
presence of an attendant! Do not disengage the drive
motors when your power chair is on an incline. The chair
could roll down on its own, causing injury!
WARNING! It is important to remember that when your
Quantum Dynamo ATS is in freewheel mode, the brak-
ing system is disengaged.
To engage or disengage the drive motors:
1. Push down the manual freewheel levers to engage the drive mo-
tors.
2. Pull up the manual freewheel levers to disengage the drive motors.
LIMITED ACTIVE-TRAC SYSTEM
Your power chair is equipped with a limited Active-Trac System (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.
