SmartDrive User’s Manual 1
1. Introduction
Intended Use of the SmartDrive
e Max Mobility SmartDrive Wheelchair Power Assist device is exclusively intended to provide auxiliary power to manual
wheelchairs to reduce the pushing power needed by their users, including pediatrics, with a user weight of 30 to 331 lbs
(14 - 150 kgs). It is intended to be used by users capable of operating and maneuvering a powered and manual wheelchair,
ultimately empowering them through enhanced mobility. It is also very strongly recommended that it be used on manual
wheelchairs that meet the “Wheelchair Compatibility” dimensions listed in the Specication Sheet.
Must Read Prior-to-Use Information
Improper use of the SmartDrive or the wheelchair it is attached, depending on surface, weather, and trac conditions, can
present a potential of injury and cause damage to the wheelchair or SmartDrive. erefore, the SmartDrive must only be
handled and used under the following prerequisites:
• e user is both physically and mentally capable of operating the wheelchair and device in all possible conditions
and situations.
• Proper instruction on its handling and operation has been received by reading and understanding this user’s manual
in its entirety.
• No technical modications have been made to the device.
• e user must take time to become accustom to the SmartDrive’s response and performance by rst practicing its
operation in a safe area that is free from hazards. One should become familiar with the push recognition, deac-
tivation response, acceleration/top speed, etc. of the device before venturing out with the device, where potentially
hazardous situations may exist. It is strongly recommended that the user not attempt to use the SmartDrive
outdoors until it can be safely operated indoors without diculty.
If any issues or malfunctions exist, cease the use of the SmartDrive and contact Max Mobility for service/further instruction.
Any contrary use to the directions of this user’s manual, to the recommendations of one’s mobility equipment dealer, or to
the technical limitations dened by either Max Mobility and one’s wheelchair manufacturer is considered to be misuse of the
SmartDrive. Max Mobility is not responsible for any injuries or damage caused by this type of misuse.
Warnings and Safety Precautions
All warnings and safety precautions issued by one’s wheelchair manufacturer must be heeded in addition to
those stated in this manual. Failure to do so could result in serious injury or death.
Handling or use of the SmartDrive by anyone who
has not received proper instruction from this manual
may result in serious injury or death.
Do not attempt to attach the SmartDrive to a wheelchair
that does not meet the dimensions outlined in “Wheelchair Compatibility” section of the Specication Sheet.
One MUST familiarize themselves with the response and
performance of the SmartDrive prior to regular use. Do
not attempt to use outdoors until it can be safely operated
indoors without colliding into walls or any other objects.
Methods for safe use of a SmartDrive attached wheelchair
are dierent for each user depending on function and ability.
e specications provided by one’s wheelchair manufacturer may be slightly aected by the addition of the
SmartDrive.
e addition of the SmartDrive to one’s wheelchair
may cause it to feel dierent. Take the time to become accustom to this new feeling.
Always inspect your drive unit, wristband, attachment
hardware and the optional thumb throttle buttons for
missing parts/damage prior to each use. See the Maintenance section for parts to pay attention to.
Make sure both the drive unit and wristband are charged
before use.
Always pay close attention to the surface that you are operating your wheelchair, whether your SmartDrive is on or
not, as the front casters of your wheelchair can get stuck in
cracks, ruts, holes, ledges, etc. Running into these obstacles can cause you to tip out of your chair.

Do not operate over signicantly rough terrain, very
slick surfaces, extreme slopes, or loose ground. is
may cause a loss of traction, leading to injury or damage to
your SmartDrive and void the warranty.
e SmartDrive is not designed to drive up or down large
curbs/steps. Only perform this maneuver when absolutely
necessary and always ask for help. Also, be sure to turn o
your SmartDrive wristband.
Use extreme caution when operating a SmartDrive attached wheelchair when near streets. Consider powering
o the wristband to reduce the chance of accident or injury.
When crossing major roads, intersection, railway crossings
or highways as well as when you drive steep, long slopes
you should always consider having somebody accompany
you in the interest of your safety.
With regards to driving up and down slopes, please adhere
to the instructions and specications given by the diverse
wheelchair manufacturers.
Riding over curbs or obstacles can cause tipping and
serious bodily harm. Turn o your SmartDrive wristband
when attempting to ride in these situations. If you have
any doubt that you can safely cross any curb or obstacle,
ALWAYS ask for help. Be aware of your riding skills and
personal limitations. Develop new skills only with the help
of a companion.
e wristband should ONLY be worn by the user sitting in
the wheelchair with the SmartDrive attached.
Use caution when operating a SmartDrive attached wheelchair indoors or in conned areas. Consider powering o
the wristband to reduce the chance of damage or injury.
Always turn the wristband o when parked to prevent accidental activation.
Always turn o your wristband before taking it o of your
wrist.
Always use caution when transferring in or out of the
wheelchair. Every precaution should be taken to reduce
the transfer distance and be certain the wheel locks are
engaged to prevent the wheels from moving. Also always
make sure the wristband is o when transferring to and
from your chair.
e optional buttons are designed to be used with
a seat cushion as to prevent sitting directly on the
cables. It is strongly recommended that a seat cushion be
used on your wheelchair when using the buttons.
e drive unit and wristband have passed industry climate
testing, the same as power wheelchairs, and is considered
rain/splash proof. Complete submersion of either may
cause malfunction or damage and void the warranty.
Surface temperatures of the SmartDrive can increase and
become hot to the touch when exposed to external sources
of heat, such as sunlight.
Using Anti-Tippers substantially reduces your risk of
falling over backwards, which can cause serious injury.
If you are afraid of tipping over, use anti-tipppers. AntiTippers will keep you from falling over, but they will limit
your ability to be pulled up curbs and some other maneuvers. Just as children learn to ride bikes without training
wheels, you may be able to learn to use your wheelchair
with Anti-tippers. It is STRONGLY recommended that
Anti-Tippers be employed to the wheelchair until the user
has become accustom to operating the SmartDrive in all
possible environments, situations, and conditions.
Do not tip or wheel your wheelchair without assistance,
unless you are highly skilled.
Do not shift your weight or sitting position toward the
direction you are reaching as one’s wheelchair may tip over
backwards or sideways.
Do not lean over the top of the back upholstery to reach
objects from behind as this may cause the wheelchair to tip
over.
Do not stand on the frame of your wheelchair.
Your wheelchair is not designed for weight training and
is unsafe from use as a seat while weight training. Weight
training from your wheelchair substantially changes the
stability of your chair and may cause tipping.
Do not attempt to stop a moving wheelchair with wheel
locks. Wheel locks are not brakes.
Do not take a SmartDrive attached wheelchair on an escalator or moving walkway. Serious bodily injury may occur.
Any modications to the SmartDrive will void the
warranty and may create a safety hazard.
NOTES: Figures and diagrams of the SmartDrive in this manual may vary slightly from your device.
An electronic version of this User’s Manual along with informational videos are available on our website
[www.max-mobility.com] for people with visual, reading or cognitive disabilities.
e Serial Number of your SmartDrive is located both on the underside of the drive unit and the bottom of the wristband.
It is recommended that you save this User’s Manual and record the Serial Number below for reference.

Electromagnetic Interference (EMI)
Electromagnetic Interference comes from radio wave sources. Examples of these sources are radio/TV station transmitters, receivers, transceivers [send and receive signals], cell phones, walkie-talkies, etc. ere are many sources of EMI in one’s
daily environment, some that are avoidable and some that one might not even realize. Powered electronic devices, such as
the SmartDrive are susceptible to EMI, both strong and weak, from these types of transmitters, as well as from electrostatic
discharges (ESD) and conducted sources. ese interferences can cause unintentional activation of the SmartDrive motor or
damage to its control system, potentially causing a safety hazard and leading to costly repairs.
Every power wheelchair or power assist device can resist EMI up to a certain level, also known as its “immunity level”. e
higher the immunity level, the less the device is at risk of interference. An immunity level of 20 V/m is understood to provide
sucient protection from the sources encountered on a daily basis. e SmartDrive has been tested and found to be immune
to this minimum immunity level of 20 V/m. ough equipped to be suciently protected against EMI, any chair modications or accessory additions can eect its immunity. Parts from other suppliers have unknown EMI properties, and their interaction with the SmartDrive is untested.
Electromagnetic energy becomes increasing more intense the closer to the source you become. erefore, it is recommended
that the SmartDrive not be operated in close vicinity to sources of radio waves. ere are three categories that EMI sources
fall under:
1. Long Range Transceivers: ese are sources of strong radio waves, including commercial radio and TV broadcast
antenna towers and amateur (HAM) radios.
2. Medium Range Mobile Transceivers: ese are sources of potentially strong radio waves, including two-way radios
used by emergency vehicles, tractor-trailers, and taxis.
3. Handheld Transceivers: ese are sources of relatively low strength waves but have the possibility of getting very
close to your wheelchair, including walkie-talkies, citizen band (CB) radios, cell phones, and other personal communication devices.
e following are not likely to cause EMI problems: Cordless phones, MP3/CD players, TV sets, and AM/FM radios.
Do not operate hand-held transceivers (transmitters-receivers), such as citizens band (CB) radios, or turn ON
personal communication devices, such as cellular phones, while the device is ON.
Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming close to them.
If unintended movement occurs, turn the device OFF as soon as it is safe.
Be aware that adding accessories or components to your wheelchair may make it more susceptible to EMI [Note: ere is
not easy way to evaluate their eect on the overall immunity of the device].
Report all incidents of unintended movement to Max Mobility, and note whether there is a source of EMI nearby.
USA / Canada
is device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) is device may
not cause harmful interference, and (2) this device must accept any interference, including interference that may cause undesired operation. Any changes or modications not expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
Bluetooth® Wireless Communication
Bluetooth® wireless communication [2.4 GHz frequency band] is used by the wristband to tell the drive unit when to deactivate the power assist, as well as to help verify that a push has been performed prior to power assist activation. e wristband must be within 25 ft (8 meters) for the two components to connect and communicate. e maximum output power of
this technology is 10 mW, and the operation of this device in close proximity to other wireless devices [i.e. electromagnetic
security systems, cellular telephones, Bluetooth® headsets] could cause the device to lose connection. Power assist is always
deactivated whenever the motor is driving and there is a loss of connection; the drive unit will beep and wristband will vibrate
as indication when this happens. Worst case coexistence testing was performed on the device to ensure its safety and eectiveness. Please contact Max Mobility immediately for troubleshooting if continuous connection issues are experienced with the
device.
