The push activated power assist can ALWAYS be deactivated by pressing the Power Assist Button on the Push-
Tracker as this turns power assist OFF / wirelessly disconnects it from the SmartDrive. If you have thumb throttle
buttons, pressing and releasing either button will also deactivate the motor if driving.
Serious care should always be taken on hills, inclines, ramps, etc.
While the PushTracker is designed to sense the tap / impact of your PushTracker wearing hand, other movements done
with your hands while the motor is driving can possibly cause activation / deactivation. Whenever power assist is be-
ing provided, it is recommended to position your hands over your handrims for steering, then a stiff wrist tap then brake
when desired to deactivate and slow down.
ALWAYS turn power assist OFF [via PushTracker] before transferring out of your wheelchair and taking the SmartDrive
off to prevent accidental activation.
Power Assist Deactivation
There are different ways to deactivate the power assist depending on which Control Mode you are operating in [see differ-
ent “Control Mode” sections]. The safest and therefore preferred way of deactivation is to perform a hitting motion with your
PushTracker wearing arm. Motion sensors in the PushTracker sense this hitting motion / tap [see graphics below] and then
deactivate the motor. Ideally, the deactivation motion will be performed by hitting your hand against the handrims with a
stiff wrist prior to braking. Sufficient deactivation motion is indicated by the LED on the PushTracker illuminating red. This
indication is given even when the motor is not driving, so practice and familiarity should be done prior to use. Depending on
your current Control Mode, a SINGLE tap or a DOUBLE tap may be required [see different Control Modes]. The sensitiv-
ity of this tap, or force / impact required, is also changeable depending on your needs [see the separate
PushTracker User’s
Manual
provided].
Whenever the motor is deactivated, the PushTracker will vibrate in addition to its LED being illuminated red as indication
that power assist is no longer being provided.
The final way to deactivate the motor is to press and release the Power Assist Button on the PushTracker. This means of deac-
tivation a red LED indication, vibration and notification on the PushTracker Display before it disconnects wirelessly from the
SmartDrive.
If any malfunctions or push detection / braking / thumb throttle button issues are experienced with the SmartDrive, cease use
of the device and contact Max Mobility for assistance.
MX2+ Control Mode
MX2+ is the default control mode for power assist [see “SmartDrive Settings” in the separate
PushTracker User’s Manual
provided for details on changing modes]. This amazing operation allows you to push around as much as you want, and then
quickly and easily get the power that you need for all situations. Operation of this mode is ideal for weaker pushers as it
allows for motor activation at the tap of the wrist. Additionally, this and all control modes can also always be used with the
thumb throttle buttons.
To activate power assist to drive in this mode, with the power assist ON and wirelessly connected, performing a DOUBLE
tap by the PushTracker worn arm will begin the motor. This will begin driving the wheelchair forward at the Acceleration
rate set in the PushTracker [see “SmartDrive Settings” in the
PushTracker User’s Manual
]. While the speed is ramping up,
performing another SINGLE tap will hold the current speed. So the SmartDrive will continue to drive, or coast, at the speed
that is reached when the SINGLE tap is performed. This is called setting your coast speed. The power assist will continue to
drive at this coast speed until a DOUBLE tap is performed / sensed or the power assist is turned OFF.
While this mode is able to start driving you from rest, it also can be activated if you are already moving where it will quickly
catch up to your speed and begin to accelerate from there. This means that you are able to give your wheelchair a quick push
to get going, then DOUBLE tapping the PushTracker will immediately activate the SmartDrive to start ramping from the
speed that you were able to reach from the push, until a SINGLE tap is performed to cruise or another DOUBLE tap is done
to deactivate the motor.
