1. Introduction
Intended Use of the SmartDrive
e Max Mobility SmartDrive Wheelchair Power Assist device is exclusively intended to provide power assist to manual
wheelchairs, empowering disabled persons, including pediatrics, capable of operating a powered and manual wheelchair by
providing a means of enhanced mobility. It is also strongly recommended that it be used on manual wheelchairs that meet the
“Wheelchair Compatibility” dimensions outlined in the Specication Sheet on Page I of this manual.
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.

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 tip or wheel your wheelchair without assistance,
unless you are highly skilled.
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 attempt to stop a moving wheelchair with wheel
locks. Wheel locks are not brakes.
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.
Make sure the battery unit is charged before use.
Always turn the unit o when parked to prevent accidental
activation.
e SmartDrive is not designed to be driven in heavy rain/
snow or on wet/icy surfaces which may cause malfunction or damage. Do not use in these conditions or on these
surfaces.
Do not operate over rough terrain, slick surfaces, extreme
slopes, or loose ground. is may cause injury or damage to
your SmartDrive and void the warranty.
Use extreme caution when operating a SmartDrive attached wheelchair in conned areas. Consider powering o
the unit to reduce the chance of damage or injury.
Use extreme caution when operating a SmartDrive
attached wheelchair when near streets. Consider
powering o the unit to reduce the chance of accident or injury.
Outdoor Mode operation of the SmartDrive is not intended to be used indoors. Use caution when using this mode of
operation, especially indoors.
As for 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 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.
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.
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
power o and consider detaching the SmartDrive drive
unit when transferring to and from your chair.
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.
e SmartDrive is designed to be used with a seat cushion.
It is strongly recommended that a seat cushion be used on
your wheelchair when using the SmartDrive.

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.
If any unintentional activation of the SmartDrive occurs, turn o the unit as soon as it is safe to do so and report the incident
to Max Mobility [please indicate any source of EMI that was in close proximity when the incident occurred].
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.

2. SmartDrive Set-Up
NOTE: Refer to the separate directions provided for a folding frame wheelchair and skip to step 4 of the “Battery Unit Clipping” section.
Adaptive Clamp Mounting
e SmartDrive adaptive clamp is designed to permanently mount to the axle tube of a wheelchair while presenting a simple
means of attaching/removing the drive unit. Slide the provided hard rubber inserts over the axle receiving tube to accommodate smaller tube diameters (see chart below for insert sizing). Use a 5 mm allen wrench to tighten the (2) screws to mount
the clamp to the axle receiving tube. e position and orientation outlined below are critical to the proper function of SmartDrive and must be heeded.
Dots (or numbers) on the side of the rubber inserts are used
to identify the tube size they t:
No Dots 1.35” or 35 mm
• 1.25” or 32 mm
•• 1.125” or 30 mm
••• 1.0” or 25 mm
CAUTION: e front and back of the clamp will not mate even
when the screws are suciently tight. As shown in the graphic
to the left, there should be a gap between the two parts. Overtightening of the screws [more than 4 ft-lbs] could cause the parts
to break during installation.
1. Make sure the “MAX” on the front of the clamp is rightside up. e protrusions coming from the side of the
clamp are to be positioned rearward with the extrusion
ats perpendicular to the ground when the chair [with
the user in it] is resting on a level plane.
Adjustments made to the wheelchair set-up could aect the orientation of the SmartDrive clamp. Adjust the
clamp whenever changes are made to the chair.
2. e clamp must be positioned midway between the two
rear wheels of the wheelchair on the axle receiving tube.
e two (2) screws should be tightened to 4 ft-lbs, xing it in this position and orientation. Failure to do this
could cause the wheelchair to not drive/ride straight and/
or the clamp to move during use causing the SmartDrive
to not function properly.

Button Mounting
e two (2) SmartDrive buttons are easily mounted to each side of the frame of the wheelchair to allow for easy pressing
without having to remove your hands from the handrims.
1. Wrap the velcro loop around the rubber backing of the
button then around the side tubing of the wheelchair;
feed the skinny end of the velcro through the slot in the
wider end and pull tightly before laying down on its mating surface. Be sure the green LED is pointing up and
the cables that come out of each button run towards the
back of the wheelchair. e plug cable should hang over
the left front side of the seat (as shown below).
NOTE: If the chair has screw-down seat upholstery, loosen
the screws and feed the velcro strap under the metal bar (then
retighten screws) to allow for closer positioning of the buttons to
the handrims.
2. Use the provided velcro strips to strap down the button cables to the upholstery, running the right button
cable around the back of the seat. Ideal placement of the
y-joint in the cable is shown to the right. Be be sure the
cable does not stick out and will not get caught in the
spokes of the wheelchair.
3. Place the cushion over the cable to further secure it.
Again, the plug should hang over the left front side of
the seat upholstery and come out from under the cushion.
SmartDrive User’s Manual 7
Drive Unit Attachment and Removal
e SmartDrive drive unit is designed to easily attach to the adaptive clamp so the user can quickly attach/remove whenever
desired or necessary. Use of the handle and the drop and lock interaction make attaching the SmartDrive simple for all users.
1. To attach the drive unit to the wheelchair, align the
ats in the adaptive clamp with the receiving slots on
the front, underside of the unit body [the drive unit will
be angled slightly higher than horizontal]. Lower the
receiving end of the drive unit over the extrusions of the
clamp.
2. Rotate the unit downward to pivotally attach the drive
unit to the clamp, and consequently the wheelchair.
3. Under its own weight, the omni-wheel end of the drive
unit rests on the ground between the rear wheels of the
wheelchair.
Remove the unit by rmly grasping the handle and performing these steps in reverse order, rst rotating upwards then
lifting the receiving slots o the adaptive clamp.

Battery Unit Clipping
NOTE: Refer to the separate directions provided for folding frame wheelchairs, chairs with less than 2 in. under-seat clearance, and
other situations (i.e. standing frames) that make attaching the the battery unit dicult; then skip to step 4 of this section.
e Battery Unit is equipped with an oversized clip for attachment to the seat of the wheelchair. e unit is made to latch
onto and hang below the upholstered seat. ere is a connector holder in the back of the battery unit to aid in cord management when handling the unit, in addition to the handle to assist in carrying/lifting.
1. Pick up the battery unit using the handle presented on
the top of the clip.
2. Lower the battery unit towards the seat of the wheelchair. Position the upholstery of the seat between the
bottom surface of the clip and the top surface of the battery housing. With the Button plug wire to the side, slide
the unit back until the front surface of the upholstered
seat is making contact with the handle.
3. Slide the battery back as far back as possible by pushing
on the front of the unit. en plug the button plug into
the jack on the front of the battery.
Under-seat c learance must be at least 2 in. for the batter y unit to sucientl y t. Any bulg ing of the wheelchair
upholstery caused by the battery unit has the potential of causing pressure sores. Cease use of the SmartDrive if
this condition exists.
SmartDrive User’s Manual 9
4. Finally, take the connector out of the connector storage
holder and plug into the top of the drive unit. ere are
white alignment arrows on the connector that should
face upward for proper connector alignment. e green
LED on top of the drive unit will light up and the unit
will beep two (2) times when proper connection is made.
e connector will automatically lock into the plug when
it is fully pushed in.
5. To unlock and disconnect the battery from the drive unit,
pull up on the outer sleeve of the connector (highlighted
in blue in the gure to the right).

3. Operating the SmartDrive
Power Assist ON/OFF
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.
When a charged battery unit is plugged into the drive unit, the SmartDrive is initially OFF. is state is indicated to the user
by the green LED on the top of the buttons not being illuminated and two (2) loud beeps. In this state, no power assist will
be able to be used by the wheelchair user. e user may push, turn and brake as they desire with negligible friction or drag
from the omni-drive wheel. e wheelchair is a fully functional manual wheelchair with no power assist.
Switching Between States
When power assist is desired, the user is able to switch the SmartDrive ON by pressing and holding either of the buttons
for more than one-half (0.5) second. e SmartDrive defaults to OFF whenever the battery unit is initially connected to the
drive unit. By pressing and holding one of the buttons then releasing, the SmartDrive will switch ON and be ready to provide
assistive power. An audio indication of one (1) loud beep is produced by the drive unit as an indication to the user that the device is now ON. Also, the green LED on the buttons will be illuminated when the SmartDrive is ON. One can switch it back
OFF by pressing and holding for more than one-half (0.5) second then releasing either button, in which the state change is
indicated by two (2) loud audio beeps from the drive unit, and the green LED on each of the buttons will turn o. e motor
must not be driving to turn the SmartDrive OFF. If the button is pressed and held for more than three (3) seconds, the button LED’s will indicate the battery level [see Battery section].
Power Assist State
e SmartDrive is equipped with two modes of power assist to aid the user is most situations encountered on a daily basis.
e rst is Indoor Mode, and the second is called Outdoor Mode. is second mode is ideal for special times when easy
power activation is needed, such as on inclines and thick carpet, and when environmental conditions are more diverse. Switcing between modes is done by pressing and quickly releasing either of the buttons with the power assist state ON and the
motor not activated. is switch is indicated by one (1) loud beep and button LED change (either solid or blinking).
Indoor Mode
When the power assist is turned ON, the SmartDrive is initially in Indoor Mode. is state is indicated by solid illumination
of the green LED on the top of each button. In this mode, 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 indoor use as it reduces the number of pushes
that you have to perform.
e SmartDrive is designed to continue to assist the user until braking is sensed, the device is turned o by pressing a button
[both described in section Braking] or until another, faster push is performed. In this case, the SmartDrive will speed up and
begin to drive the user at this faster speed attained when the user pushed harder.
If any malfunctions or push detection/braking/push-button issues are experienced with the SmartDrive, cease use of the
device and contact Max Mobility for 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.
In addition to braking the handrims in Indoor Mode, the push activated power assist can always be stopped by quickly
pressing and releasing the push-button.
Care should be taken when taking the SmartDrive down an incline. Consider switching the device OFF when descending down a slope.
e acceleration of the SmartDrive could cause the wheelchair to tip-over backwards, causing injury. It is recommended
that the user lean slightly forward to prevent this tipping.
SmartDrive User’s Manual 11
Braking
In addition to recognizing pushes, the SmartDrive is also able to sense when one is braking. When the user slows the wheelchair down with pinching of the handrims, the drive unit senses the braking and deactivates the power assist. If a push is
performed after, then the power assist will turn back on and drive the user.
In addition to braking, a user who chooses to stop the power assist at any time is able to do so by pressing either of the buttons. e device will continue to be in its current mode if the power assist is stopped by pressing a button.
If any malfunctions or push detection/braking/push-button issues are experienced with the SmartDrive, cease use of the
device and contact Max Mobility for assistance.
Regular braking technique should be practiced when using the SmartDrive. In certain situations, especially at
higher speeds, harder braking will be required to turn o the power assist.
In addition to braking, the push activated power assist can ALWAYS be stopped by pressing either of the buttons.
Always be aware of which mode you are in by looking at the green LED’s on the top of the button.
Outdoor Mode
Outdoor Mode is the second mode. Switched to this mode by pressing and quickly releasing either button when the SmartDrive is in Indoor mode and the motor is not driving [the drive unit do one (1) loud beep]. Also the green LED on the buttons will continually blink while you are in Outdoor Mode. Regular check which mode you are in by looking at these LED’s.
In this mode, there is Easy Start that allows the user to easily activate the motor and reach one of the four speed steps that
are pre-programmed. e four speed steps that can be driven at are 1.5 mph, 2.5 mph, 3.5 mph and maximum speed which is
shown on the Specication Sheet [see page I]. e SmartDrive will sense which step your push was closest to reaching and
activate the motor to drive at that step’s speed. A faster speed step can be reached while the motor is powering at the lower
speed by performing another harder push.
is Easy Start activation in Outdoor Mode is especially useful when on a steep hill, incline, ramp, etc. where it might be difcult to reach a sucient speed for Indoor Mode power activation.
In Outdoor Mode, the power assist is ONLY able to be deactivated by pressing one of the buttons. Once a push is performed
and the motor is activated, position your hands over your handrims and buttons to be prepared to turn o the motor when
braking/deactivated power is needed.
Anytime that the power assist is stopped by a button press in Outdoor Mode, automatic rollback resistance lasting (3) seconds will be provided to prevent the wheelchair and the user from rolling backwards, which is especially helpful on hills and
inclines. Whenever the rollback resistance is not activated, the SmartDrive will roll backwards freely.
e SmartDrive will continue to be in Outdoor Mode after the power assist is stopped by a button press. Another performed
push will reactivate the motor, again ONLY to be deactivated by a button press. To get back into Indoor Mode, with the
motor not activated, press and quickly release one of the buttons; the drive unit will produce one (1) loud beep and the green
LED’s on the button will turn to solid illumination. Switch to power assist OFF state by pressing and holding one of the buttons for more than one-half (0.5) seconds while the motor is not activated. is switch will be indicated by two (2) loud beeps
and the LED’s on the buttons will turn o.
If the button is pressed and held for more than three (3) seconds, the button LED’s will indicate the battery level [see Battery
section].
Outdoor Mode operation of the SmartDrive is not intended to be used indoors. Use caution when using this mode
of operation, especially indoors.
e buttons should be positioned in close proximity to the handrims to allow for easy pressing access.
e acceleration of the SmartDrive could cause the wheelchair to tip-over backwards, causing injury. It is recommended
that the user lean slightly forward to prevent this tipping.
Serious care should be taken on all hills, inclines, ramps, etc.
(Continued on next page)
12 max mobility
e rollback resistance may not be able to prevent the slow rolling back on especially steep slopes and/or very
heavy wheelchair users.
Rollback resistance 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:
• Long carpet
• Slick or wet tile
• Loose dirt or gravel
• Standing water
e total weight of the SmartDrive assembly is 19.8 lbs. 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.
If any part of the SmartDrive is accidentally gotten wet, the user should cease usage and allow 12 hours for it to air dry before
attempting to use again.
e operating temperatures of the SmartDrive are -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.
• Icy surfaces
• Rough terrain
• Extreme slopes
• Heavy rain or snow
4. Battery
Although the battery on the SmartDrive 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.
e battery unit houses the rechargeable Lithium Iron Phosphate batteries used to power the SmartDrive. e newest in
Lithium-Ion technology, these batteries oer a signicantly longer cycle life and faster charging rate than standard lithium
ion cells.
e green LED on the top of the buttons is used to indicate the battery charge level. In any mode or state with the motor not
activated, press and hold either of the buttons for more than three (3) seconds. e LED’s will then blink to show the battery
charge level. ree (3) successive blinks mean you have greater than 70% battery capacity. Two (2) blinks indicate that you
have between 70% and 30% capacity. One (1) single blink indicated that the battery is less than 30% capacity and should be
charged as soon as possible.
Avoid getting the battery unit wet, for this can cause a short. It is also recommended to always place the connector in the
connector holder on the back of the battery unit whenever it is not plugged into the drive unit.
Long-term storage of the battery [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.
Always store and charge the battery in a cool, dry area. Hot and damp environments can damage or short the unit,
requiring a costly replacement.
Avoid dropping of the battery unit.
Never get the battery unit wet. is can cause a short or permanently damage the battery unit.
Only use the provided charger to recharge the battery of the SmartDrive. Other chargers may damage your unit, or cause
a re.
