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.

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.
The best way to climb ramps and inclines is to go slow. On cross-slopes, activate the motor to begin driving, then brake with
the uphill hand on the wheelchair handrim to go straight.
Also, rollers on the omni-drive wheel allow for pivoting of the wheelchair as they smoothly roll side-ways over surfaces. Care
should be taken to make sure the SmartDrive doesn’t get caught on things like curbs or small sidewalk cracks when you pivot.
The attachment hardware is designed to fail first, so if you get the SmartDrive stuck, this can break the clamp / folding adap-
tor bar and leave you without power assist. Sometimes it is best to turn the SmartDrive off, negotiate the situation manually
and then start using the assistive power again.
If any part of the SmartDrive is accidentally submerged or doused in water, the user should cease usage and allow 12 hours
for it to air dry before attempting to use again. It is recommended to always store the SmartDrive and PushTracker indoors.
If your device has been stored in extreme temperatures, allow time for it to warm up or cool down prior to use.
The operating temperature of the SmartDrive is between -25 oC and 50 oC
If any malfunctions or issues are experienced with the SmartDrive, cease use of the device and contact Max Mobility for as-
sistance.
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:
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.
Refer to and heed all warnings for MX2 control mode.
