Thumb Throttle Button Instructions (continued)
Refer to the SmartDrive User’s Manual prior to use for further instruction on how to operate the SmartDrive.
Also, heed all warnings and cautions outlined in that manual.
Button Operation/Activation
The thumb throttle buttons are used to activate the power assist without having to perform a push. This is done by pressing [with the
0.9 lbs (4 N) minimal needed force] and holding either of the frame mounted buttons [with the drive unit turned on and the buttons
plugged in] for longer than one (1) second, at which point the drive unit motor will start to drive. As either of the buttons is held, the
drive unit will slowly ramp up its speed at a slow rate of 2 ft/s
2
to a maximum speed of 1.5 mph (2.4 km/h). This is a slow, comfortable
walking speed. Releasing the pressed button at anytime will deactivate the motor/power assist. If the motor is driving when the button
is pressed, it will first deactivate the motor. If it is continued to be held, then the motor will start to drive, slowly ramping its speed up.
This button activation is especially helpful in cases where performing a push is difficult, like when on hills or in thick carpet.
The buttons should be placed as close to the wheelchair wheels as possible to allow for easy pressing without having to remove your
hands from the handrims. Steering is still done by braking on the handrims, and as soon as the pressed button is released, the omni-
drive wheel is deactivated. Remember that the device will still be in a state of power assist ready, so a performed push [when used with
a wristband] or press and hold of either of the buttons will re-activate the motor. Whenever a wristband is used, please note that press-
ing and releasing the button on the top of the wristband will deactivate the motor and turn it off, so the SmartDrive will not provide
power assist activated by a push, but the buttons can still be used.
If any malfunctions or thumb throttle button/deactivation/push detection issues are experienced with the SmartDrive, cease use of the
device and contact Max Mobility for immediate assistance.
