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.

SmartDrive User’s Manual 3
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.

2. SmartDrive Set-Up
Drive Unit Attachment
e SmartDrive is designed to easily and quickly attach to all types of manual wheelchairs, both rigid and folding. Refer to
the Specication Sheet to verify the compatibility of the wheelchair.
Use the separate directions provided with your drive unit attachment hardware for correct set-up prior to use.
Adjustments made to the wheelchair set-up could aect the orientation of the SmartDrive. Adjust the
attachment hardware, if needed, whenever changes are made to the chair or its wheels.
Wristband Install and Attachment
e wristband module is designed to be easily installed into the wrist band of size that securely holds it to the top part of
your wrist. It has an embedded accelerometer that veries that your hands are pushing on your handrims before activating the
power assist, and also senses when you tap your hand against the handrim to deactivate the power assist. Additionally, it is
equipped with an LED and vibration motor to indicate dierent states and activations/deactivations that occur during operation.
Each new SmartDrive drive unit is shipped with a wristband module that is specically paired to it to prevent communication with other drive units. is is indicated by the same last four (4) digits in the serial number on each [i.e. drive unit serial
number 201234 is paired with wristband module serial number A21234].
Use the separate directions provided with your wristband for module installation and attachment instructions.
Thumb Throttle Buttons [sold separately]
e two (2) SmartDrive frame mounted thumb throttle buttons are easily mounted to a wheelchair to allow for close access
and easy pressing. e buttons can be used to deactivate the motor, as well as provide a means of actively powering the motor.
ese are sold separately as an optional accessory. Use the separate directions provided with the buttons for correct set-up and
operation prior to use.
3. Operating the SmartDrive
Training Mode
SmartDrives are shipped in training mode to allow for familiarity and wristband deactivation practice prior to extensive
use. Training mode is indicated by green [and red] LED indication on the wristband [instead of blue and red for normal
operation as described in the following section]. In this mode, the deactivation means is the same as normal operation [see
Deactivation section], but you are also able to deactivate the power assist by braking on the handrims of the wheelchair.
e SmartDrive recognizes the deceleration that the wheelchair experiences from the braking and turns the motor o. is
mode should be used to perfect the tapping motion needed by the wristband to deactivate the motor, upon which it is time to
switch to normal operation to get the most our of your SmartDrive in all the environments encountered on a daily basis. To
get out of training mode, just press and hold the button on the wristband for ve (5) seconds, at which point you will feel a
vibration and see the wristband LED change to blue; then release the button. You are now in normal operation and can only
deactivate the power assist with the wristband/tapping.
Power Assist Ready
e user of a SmartDrive equipped wheelchair is able to use the power assist whenever desired or turn the device o and
operate their wheelchair as if the SmartDrive was not on their chair.
With the drive unit already attached to the wheelchair and powered on [as described in the attachment hardware directions],
the SmartDrive will wait for the specically paired wristband to be powered on. e wristband is turned on by pressing and
releasing the button on its top side. Once the wristband is turned on [as indicated by the LED on the wristband giving a blue
ash every (1.5) seconds and a single vibration] it will attempt to wirelessly connect to the drive unit. Whenever the wristband is attempting to wirelessly connect to the drive unit, whether because of a loss of connection or from initially turning the
wristband on, the LED on the wristband will ash red. When the wireless connection is made or regained, the red ashing
will stop. Once the wristband has wirelessly connected to the drive unit, the SmartDrive power assist is ready and waiting for
a push to be performed to provide assistive power.
6 max mobility
Pressing and releasing the button on the top of the wristband will turn it o. If the wristband has been turned o, the indication LED will cease from ashing and a double vibration will be given. With the wristband o, the drive unit will not be able
to activated to provide power assist, so you are able to push the wheelchair around with no power assist.
®
Cruising Power Assist
With the power assist ready [the drive unit and wristband both on and wirelessly connected], the SmartDrive is able to recognize when you have performed a push on the wheelchair. In turn, the device activates the omni-drive wheel, and an assistive
drive power is provided, propelling you at a speed equal to that which was attained by the push. e SmartDrive is able to
recognize each individual’s push, so no alterations to one’s propulsion technique is needed. is is ideal for everyday use as it
reduces the number of pushes that have to be performed. Push recognition and motor activation is indicated to the user by a
vibration in the wristband and the LED being illuminated solid blue.
e SmartDrive is designed to continue to drive the user until a tapping motion is performed by the wristband worn arm
or the wristband is turned o [as described in the Power Assist Ready section] OR until another, faster push is performed.
In this last case, the SmartDrive will speed up and begin to drive the user at this faster speed attained when the user pushed
harder [a single vibration will be given while the LED on the wristband will continue to stay lit blue]. 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 o the motor when braking/deactivated power is desired.
Refer to the Specication Sheet for the maximum speed that the SmartDrive is able to drive from push activation.
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.
e 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 the SmartDrive on a decline. Consider switching the wristband o when descending
down a slope.
e acceleration of the SmartDrive could possibly cause the wheelchair to tip-over backwards, causing injury. It is recommended that the user lean slightly forward to prevent this tipping.
Deactivation
As mentioned in the prior section, there are multiple ways to deactivate the power assist. e safest and therefore preferred
way of deactivation is to perform a hitting motion with your wristband wearing arm. Motion sensors in the wristband sense
this hitting motion [see graphics below] and then deactivate the motor. Ideally, the deactivation motion will be performed by
the user hitting their hand against their handrims with a sti wrist prior to braking. Sucient deactivation motion is indicated by the LED on the wristband illuminating red for one (1) second. is indication is given even when the motor is not
driving, so practice and familiarity should be done prior to use.
Whenever the motor is deactivated, the wristband will vibrate in addition to its LED being illuminated red as indication that
power assist is no longer being provided.
e nal way to deactivate the motor is to press and release the button on the wristband. is means of deactivation will give
a double vibration and red LED indication before the wristband turns o.
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.
SmartDrive User’s Manual 7
e push activated power assist can ALWAYS be deactivated by pressing the wristband button to turn it o. 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 wristband is designed to sense the tap/impact of your wristband wearing hand, other movements done with
your hands while the motor is driving can possibly cause deactivation. Whenever power assist is being provided, it is
recommended to position your hands over your handrims for steering, then a sti wrist tap then brake when desired to
deactivate and slow down.
ALWAYS turn your wristband o before transferring out of your wheelchair and taking the drive unit o to prevent accidental activation.
Anti-Rollback
Anytime that the power assist is deactivate on an incline or due to a loss of wireless connection [the drive unit will beep for
this second case], automatic rollback resistance lasting (3) seconds will be provided to prevent the wheelchair and the user
from rolling backwards. 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.
e 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 the secure your wheelchair with brakes if stopping on a slope is desired.
Operating Conditions
e 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:
• Loose dirt, sand or gravel
• Standing water
• Icy surfaces
e total weight of the SmartDrive assembly is 13.5 lbs (6.1 kg). is 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.
e best way to climb ramps and inclines is to go slow. On cross-slopes, perform a push to get the motor 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 drive unit doesn’t get caught on things like curbs or small sidewalk cracks when you pivot.
e attachment hardware is designed to fail rst, so if you the drive unit stuck, this can break the clamp/folding adaptor bar
and leave you without power assist. Sometimes it is best to turn the SmartDrive o, negotiate the situation manually and then
start using the assistive power again.
• Rough terrain
• Extreme slopes
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 drive unit and wristband indoors. If
your device has been stored in extreme temperatures, allow time for it to warm up or cool down prior to use.
e operating temperature of the SmartDrive is between -25 C and 50 C
If any malfunctions or issues are experienced with the SmartDrive, cease use of the device and contact Max Mobility for assistance.

4. Batteries
Although the battery in the SmartDrive drive unit is very small and compact, it can store a large amount of power.
Faulty handling or storage can damage the equipment, and in some cases result in shocking, burns, or re.
Battery Information
e drive unit houses the rechargeable Lithium Iron Phosphate battery used to power the SmartDrive motor. e newest in
Lithium-Ion technology, these batteries oer a signicantly longer cycle life and faster charging rate than standard lithium
ion cells.
e blue LEDs on top of the drive unit are used to indicate the battery charge level. All four (4) LEDs being illuminated
indicate a full battery. As the charge of the battery decreases, so does the number of LEDs being lit. e drive unit will give
a beep whenever the battery is below 20% and the power assist is activated to let you know charging of the battery should be
done as soon as possible to avoid running completely out.
Low wristband battery is indicated by the LED on the wristband ashing blue then red every (1.5) seconds when on. Again,
charging of this battery should be done as soon as possible to avoid running completely out.
It is encouraged to charge each battery every night to avoid running out of charge during daily use. e life of the battery will
not be deteriorated by charging when it is partially drained.
Make sure the charging receptacles are completely dry and free from debris [as the magnets can attract some] before plugging
in the charger, for this can cause a spark or short. Blow water out of the receptacle if you suspect there being water in it. It is
also recommended to always cover the button/charger receptacle whenever either are not plugged into the drive unit.
Long-term storage of the batteries [more than 3 months] reduces its capacity through spontaneous discharge. Charge the
battery to at least 30% before you store it long-term, and avoid storing the unit where the temperature is too high or with
high humidity.
Drive Unit Battery Charging
Only use the provided charger to recharge the drive unit of the SmartDrive. Other chargers may damage your unit,
or cause a re. Also, always power o and never attempt to use the drive unit while charging.
e battery charger is to be used indoors and in dry locations. Use an easily accessible outlet that is close to drive unit that
is to be charged.
Do not use or attempt to repair a damaged/defective charger. Contact Max Mobility if a charger is damaged and do not
dispose of in your household garbage.
e charging transformer box is intended to be laid at during charging.
Only use the power supply cord provided with the charger. e charger is capable of operating at dierent voltages without adjustment.
To charge the drive unit, plug the battery charger cable into a wall outlet, at which point the green LED on the charger box
will illuminate. Connect the magnetic charger connector to the powered o drive unit magnetic receptacle [moving the rubber plug to the side]. e magnets in the connectors will only allow the plug to connect in one direction. Once the unit is
connected and charging, the LED on the charger will turn red. When the LED on the charger turns back to green, the drive
unit is fully charged. Remove the connector from the drive unit and replace the rubber cap to protect the receptacle on the
drive unit. e estimated charge time for a full recharge of the drive unit battery is approximately 3 hours.
Wristband Battery Charging
Plug the provided wall adapter into a wall outlet and plug the USB cable [standard USB type A] plug into the wall adapter
[this can also be done prior to plugging into the wall]. en plug the USB connector [standard USB type micro-B] into the
small port on the side of the wristband module making sure the it is powered o. e LED indicator light on the wristband
will be red while the unit is charging, and will turn green once the battery is fully charged. e wristband can be charged using any standard USB [type A] port found on a computer, car charger with USB plug, etc. and any type A to micro-B cable.
e estimated charge time for a full recharge of the wristband battery is approximately 2.5 hours.
SmartDrive User’s Manual 9
Always store and charge the drive unit and wristband in a cool, dry area. Hot and damp environments can damage
or short the unit, requiring a costly replacement.
Make sure the charging receptacles are completely dry before plugging in the charger, for this can cause a spark or short.
Also, always power o and never attempt to use the wristband while charging.
Do not throw away the drive unit or wristband. Please properly dispose of each by recycling at the
end of its life or send it back to Max Mobility.
Travelling and Shipping
Because the SmartDrive drive unit houses a Lithium-Ion battery, special considerations have to be taken when travelling on
an airplane. e SmartDrive must be carried onto your plane and should be stored in the overhead bin. It is recommended
that advanced arrangements be made with each airline operator and approval received prior to departure date. A “SmartDrive
Airline Passenger Certicate” can be downloaded from the Max Mobility website [www.max-mobility] or provided upon
request.
Use the provided foam stand for the drive unit to prevent movement and damage when transporting in a car. If riding in a
cab, it is recommended to have the driver hand you the drive unit so that it doesn’t get damaged from movement when placed
in the trunk.
Also, special considerations need to be taken when shipping the SmartDrive due to the battery. Contact the shipping company being used for instructions on how to correctly package and label prior to shipping. Be sure to provide plenty of padding/
protection for the drive unit to prevent damage.
5. Maintenance
Inspection
Always inspect the drive unit, omni-drive wheel, wristband, attachment hardware and thumb throttle buttons for missing
parts/damage prior to each use. Cease use and contact Max Mobility or your mobility equipment dealer if you notice any of
the following:
• Broken or cracked plastic
• Any of the rollers do not spin with little resistance, have ats worn in them or any other signicant damage
• Signicantly worn down rollers and/or damaged wheel plastic
• Ripping rubber on the wristband
• Missing or loose screws
• Adaptive clamp has rotated downward [on rigid wheelchairs]
• Broken or fraying cables
• Magnetic receptacle or plug has collected metal shards
• Any abnormal motor activation/deactivation activity [during use]
Cleaning
Cleaning of the SmartDrive can be done by wiping all of the parts down with a damp wash rag. is should be done at least
once a month, or as needed.
Roller Lubricating or Replacement
e omni-drive wheel contains 16 rubber rollers that may wear down, depending on
driving conditions, after extensive use. ese rollers are able to be replaced. Also, in
snowy climates, salt may cause corrosion to the bearings on these rollers and aect
their performance. Spraying lubrication on these bearings will increase their usable
lives (see graphic to the right). Contact your mobility equipment dealer or Max Mobility for information on replacing/maintaining the rollers on your SmartDrive unit.

Other Maintenance
Contact Max Mobility or your mobility equipment dealer for any other maintenance or replacement that the device might
need.
Troubleshooting
Safeguards are designed to prevent damage to the drive unit circuit board and battery from other part failures or atypical situations. Here is a list of these safeguards, how they are indicated and how to address them:
• Two (2) blinking drive unit LEDs indicate a bad motor. e motor will have to be replaced before it is operable again.
• ree (3) blinking drive unit LEDs indicate a current spike. e drive unit will need to be turned o and then on to use
again.

Client
I certify that I have read the User’s Manual and demonstrated the skills checked above. I accept that the SmartDrive can
be dangerous if not used carefully and I take responsibility for making responsible driving choices while using it. I understand there are many situations where the SmartDrive should be turned OFF to prevent it from unintentionally powering
forward, including: downhill slopes, up or down curbs, climbing large sidewalk cracks, while in conned spaces, before
handling the drive unit and transferring into and out of my wheelchair.
