14 Jazzy 1120
2000
ACTIVE-TRAC SYSTEM
Your Jazzy is equipped with an Active-Trac System (ATS). ATS is a suspension system designed to make your
Jazzy 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 the Jazzy 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 Jazzy 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.
REAR SUSPENSION
Your Jazzy 1120
2000
is equipped with Rear Suspension. See figure 9. This suspension system works in conjunction
with the ATS and is designed to maintain a smooth ride when driving over rough terrain and up and down curbs.
This system works by allowing the caster forks to respond to weight transfers and uneven terrain. The rear caster
wheels will pivot as you drive over obstacles. This system also enhances performance when the front anti-tip wheels
are set lower to the surface.
