Anti-Rollback
The SmartDrive is equipped to provide rollback resistance whenever power assist is activated while the wheelchair is moving
backwards. This is a safety feature that requires the wheelchair to be at rest to begin driving. Whenever the rollback resistance
is not activated, the SmartDrive will roll backwards freely.
As warned before, serious care should be taken on all hills, inclines, ramps, etc.
The rollback resistance may not be able to prevent the quick rolling back on especially steep slopes and / or for very
heavy wheelchair users.
Anti-rollback is not a parking brake. Be sure to secure your wheelchair with brakes if stopping on a slope is desired.
• Loose dirt, sand or gravel
• Standing water
• Icy surfaces
• Rough terrain
• Extreme slopes
The total weight of the SmartDrive assembly is 13.5 lbs (6.1 kg). This weight should be included in calculating the on-board
weight of the wheelchair. The maximum allowable on-board weight outlined by one’s wheelchair manufacturer should never
be exceeded with the addition of the SmartDrive.
Operating Conditions
The SmartDrive is designed for typical operating conditions encountered by a manual wheelchair user on a daily basis. Max
Mobility recommends restricting the use of this device to indoor and light outdoor use. All operating conditions set forth by
one’s wheelchair manufacturer should always be heeded, in addition to the avoidance of the following:
MX2 is designed to continue to drive you until a SINGLE tap is performed by the PushTracker worn arm or the power assist
is turned OFF to deactivate the motor [as described in the
Power Assist Deactivation
section] OR until another, faster push
is performed. In this last case, the SmartDrive will speed up and begin to drive at this faster speed attained when you pushed
harder. Once a push is performed and the motor is activated, position your hands over your handrims [and thumb throttle
buttons, if present] to be prepared to turn off the motor when braking / deactivated power is desired.
Refer to “SmartDrive Settings” in the separate
PushTracker User’s Manual
provided on how to change / limit the Maximum
Speed that the SmartDrive is able to activate and drive.
If any malfunctions or push detection / deactivation / thumb throttle button issues are experienced with the SmartDrive,
cease use of the device and contact Max Mobility for immediate assistance.
Refer to and heed all warnings for MX2 control mode.
The SmartDrive is able to recognize all types of pushes. Do not alter the way that you push for this could lead to
injuries in the future.
Care should be taken when using on a decline in all control modes. Consider switching the power assist OFF [via Push-
Tracker] before descending down a slope.
The acceleration of the SmartDrive could possibly cause the wheelchair to tip-over backwards, causing injury. It is recom-
mended that the user lean slightly forward to prevent this tipping.
MX1 Control Mode
MX1 mode [formerly known as “Beginner Mode”] is one of the other options for the power assist Control Mode that can
be selected [see “SmartDrive Settings” in the separate
PushTracker User’s Manual
provided]. In this mode, the deactivation
means is the same as MX2 mode [see “MX2 Control Mode” and “Power Assist Deactivation” sections], but you are also able
to deactivate the power assist by braking on the handrims of the wheelchair. The SmartDrive recognizes the deceleration that
the wheelchair experiences from the braking and turns the motor off. This mode can be used effectively indoors and to perfect
the tapping motion needed by the PushTracker to deactivate the motor, upon which it most likely is time to switch to either
MX2 or MX2+ mode to get the most out of your SmartDrive in all the environments encountered on a daily basis.
