SmartDrive User’s Manual 1
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 exclusively intended to be used on manual wheelchairs that meet the
“Wheelchair Compatibility Requirements” outlined in the Specication 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 trac 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 modications 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 recogni-
tion, braking response, acceleration/top speed, etc. of the device before venturing out with the device, where poten-
tially 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 diculty.

Do not shift your weight or sitting position toward
the direction you are reaching as one’s wheelchair
As for driving up and down slopes, please adhere to the
instructions given by the diverse wheelchair manufacturers
accordingly.
Riding over curbs or obstacles can cause tipping and seri-
ous bodily harm. 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 have 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 disattach the SmartDrive drive unit when
transferring to and from your chair.
Always power o the drive unit and consider removing
when transferring from the wheelchair.
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.
Do not take a SmartDrive attached wheelchair on an
escalator or motorized walkway. Serious bodily injury may
occur.
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.
Do not attempt to attach the SmartDrive to a wheelchair
that does not meet the specications outlined in “Wheel-
chair Compatibility Requirements” in the Specication
Sheet on Page I of this manual.
Any modications to the SmartDrive will void the
warranty and may create a safety hazard.
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. Anti-
Tippers will keep you from falling over, but they will limit
your ability to be pulled up curbs and some other maneu-
vers. 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 malfunc-
tion 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

SmartDrive User’s Manual 3
Electromagnetic Interference (EMI)
Electromagnetic Interference comes from radio wave sources. Examples of these sources are radio/TV station transmit-
ters, 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
sucient 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 suciently protected against EMI, any chair modications or accessory additions can eect its im-
munity. 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 com-
munication 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 unde-
sired operation. Any changes or modications not expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.

2. SmartDrive Set-Up
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. Remove the backing of the adhesive on both parts of the clamp, and use a 3/16”
allen wrench to signicantly tighten all the four (4) screws to mount the clamp to the axle receiving tube. e following posi-
tion and orientation are critical to the proper function of SmartDrive and must be heeded:
1. e protrusions coming from the side of the clamp are to
be positioned rearward with the extrusion ats perpen-
dicular to the ground when the chair [with the user in it]
is resting on a level plane.e screws should be tightened
as much as possible so to prevent rotation or translation
of the clamp.
2. e clamp must be positioned midway between the two
rear wheels of the wheelchair on the axle receiving tube.
All four (4) screws should be tightened as much as possible,
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 Smart-
Drive to not function properly.
Adjustments made to the wheelchair set-up could aect the orientation of the SmartDrive clamp. Adjust the
clamp whenever changes are made to the chair.

6max mobility®
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 perform-
ing the steps in reverse order, rst rotating upwards then
lifting the receiving slots o the adaptive clamp.
Never attempt to remove the drive unit from the clamp while still seated in the wheelchair. is presents a serious
risk of tipping over and injury.

SmartDrive User’s Manual 7
Battery Unit Clipping
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 manage-
ment 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 wheel-
chair. Position the upholstery of the seat between the
bottom surface of the clip and the top surface of the bat-
tery housing. 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.
Under-seat clearance must be at least 2 in. for the battery unit to suciently t. Any bulging 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.

8max mobility®
4. Finally, take the connector out of the connector storage
holder and plug into the top of the drive unit. 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.
Use extreme caution when attempting to plug or unplug the connector while seated in the wheelchair. is presents
a serious risk of tipping over and injury.
Never use the wheelchair as support when clipping/removing the battery unit. Always hold onto a solid structure [i.e.
railing, car seat, etc.] when placing the battery unit.
5. Lock the connector into the plug by rotating the connec-
tor outer-sleeve clockwise.

SmartDrive User’s Manual 9
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 front of the battery unit 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 quickly releasing the push-button
presented on the front of the battery unit. e SmartDrive defaults to OFF whenever the battery unit is initially connected
to the drive unit. By pressing and releasing the button on the battery unit within two (2) seconds, 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 front of the battery unit will be illuminated
when the SmartDrive is ON. One can switch it back OFF by pressing and quickly [within one-half (0.5) second] releasing
the push-button, in which the state change is indicated by two (2) loud audio beeps from the drive unit, and the green LED
on the front of the battery unit will turn o. If the button is pressed, but held and not released within two (2) seconds in
attempting to switch the device ON, it will stay OFF and provide the typical indication of this state [two (2) beeps and the
green battery LED o ]. e button must be released within two (2) seconds of pressing to switch the power assist from OFF
to ON.
Power Assist Mode
e SmartDrive is equipped with two ways of activating the power assist driving force to aid the user is most situations en-
countered on a daily basis.
e rst way is by push activation, and the second by using the push-button, ideal for special times when active driving power
is needed, such as climbing a long slope or powering through thick carpet.
Push Activation
When the power assist is ON, 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 you have to perform.
e SmartDrive is designed to continue to assist the user until braking is sensed, the device is turned OFF [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 push activated power assist can always be stopped by quickly pressing and releasing the push-
button, thus switching the power assist OFF.
Care should be taken when taking the SmartDrive down an incline. Consider switching the device OFF when descend-
ing down a hill.

10 max mobility®
Button Activation
e second way of activating the omni-drive wheel is by pressing and holding the push-button on the front of the battery
unit. While stationary and with the power assist ON, when the user presses and holds the button, the device will begin to
produce a beep. If the button is continued to be held through the beep [for at least two (2) seconds from when the button is
initially pressed], the omni-drive wheel is slowly activated, driving the wheelchair forward until the button is released. Once
the button is released, the unit will continue to drive, or coast, at the speed that is reached when the button is released. e
device will continue to drive at this speed unit a brake is sensed or the power assist is turned OFF [both described in the next
section].
If the button is released within one-half (0.5) second of the initial button press [and beep], the power assist mode will switch
to OFF.
But if the button is released during the beep, between one-half (0.5) and two (2) seconds from the initial button press, the
next push performed by the user will be a PowerPush [see next section PowerPush for details].
Additionally, anytime while already moving and with power assist ON, the user may press and hold the button for at least
one-half (0.5) second to increase the coasting speed. Again, the unit will accelerate and set the coast speed to that which is
achieved when the button is released. Steering is still done by pinching on the handrims of the wheelchair [the SmartDrive
does not provide any brake assistance]. e maximum speed that button-hold activation will allow the motor to reach is 4.5
mph on a smooth, level surface, at a comfortably slow, safe acceleration.
When the coast is deactivated by braking, it will still be in a state of power assist ON, so you will be able to perform a push
or press and hold the button in order to re-activate the motor for power assist. As always, quickly pressing and releasing the
button will switch the state of the device, in this case turning the device OFF [described in the next section].
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.
Braking
In addition to recognizing pushes, the SmartDrive is also able to sense when one is braking. When the user slows the wheel-
chair 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.
Anytime that a brake is sensed by the device, automatic rollback resistance lasting between one (1) and ve (5) seconds will be
provided to prevent the wheelchair and the user from rolling backwards, especially helpful on hills and inclines. e duration
of the rollback resistance is dependent on the severity of the incline that the SmartDrive attached wheelchair is encountering.
e steeper the incline, the longer the rolling resistance will be activated. e longest that this resistance will be provided is
ve (5) seconds. Whenever the rollback resistance is not activated, the SmartDrive will roll backwards freely.
In addition to braking, a user who chooses to stop the power assist at any time is able to do so by pressing and quickly releas-
ing the push-button on the front of the battery unit, switching the device OFF. If the button is not released within one-half
(0.5) second of pressing, the device will stay ON and Button Activation [described on page 10] will occur.
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, slightly harder
braking may be required to turn o the power assist.
In addition to braking, the push activated power assist can always be stopped by quickly pressing and releasing the push-
button.
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.
e acceleration of the SmartDrive could cause the wheelchair to tip-over backwards, causing injury. It is recom-
mended that the user lean slightly forward to prevent this tipping.

SmartDrive User’s Manual 11
PowerPush
As mentioned in a previous section, the SmartDrive is equipped with a PowerPush function. When activated, a PowerPush
provides a power assistance that is approximately 1.5 times that achieved by the performed push. is type of assistance is
especially useful when encountering a steep hill, incline, ramp, etc. where it might be dicult to reach a sucient speed for
regular Push Activation.
PowerPush is designed to be used in one of two situations. e rst is when stationary [most likely at the bottom of an
incline], with the power assist ON, once the button is pressed the unit will begin to produce a beep. If the button is released
during the beep [between one-half (0.5) and two (2) seconds from initial pressing], the next push recognized will activate the
power assist to drive at a speed 1.5 times that reached from the push.is is called a PowerPush, and only the next push after
activation will be this way.
e PowerPush power assist is able to be deactivated same as typical push deactivation, either by braking on the handrims and
slowing down or by turn the power assist OFF by pressing and quickly releasing the button.
If the button is pressed and held through the beep [longer than two (2) seconds], the SmartDrive will begin to slowly ramp up
the power assist speed as described in the Button Activation section [see page 10].
e second situation to use PowerPush is when the user is already travelling up an incline or hill. If when moving up the
slope the device senses a brake and rollback resistance is activated, the user can activate a PowerPush by pulling back on the
handrims of the wheelchair against the rollback resistance for one (1) second. If done correctly, the unit will produce one (1)
loud beep to notify the user that the next push performed will be the PowerPush. Again, only the next push after activation will
be a PowerPush, and the user has only ve (5) seconds from the brake sense/rollback resistance engagement to activate this
function.
Again, deactivation of the power assist is able to be done same as a typical push, either by braking on the handrims and slow-
ing down or by turn the power assist OFF by pressing and quickly releasing the button [within one-half (0.5) seconds].

e total weight of the SmartDrive assembly is 19.6 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 exceed-
ed 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 as-
sistance.
PowerPush is designed to only be used in situations where higher power assistance is needed, as on steep hills, in-
clines, ramps, etc. It should only be used in these situations.
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. as to prevent accidental activation of PowerPush.
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:

12 max mobility®
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 oer a signicantly longer cycle life and faster charging rate than standard lithium
ion cells.
e red LED on the front of the battery unit is designed to light up when the charge level of the battery is below 30%. When
this light comes on, look to recharge the battery unit as soon as possible. Refer to the Instructions Manual provided with the
charger for directions on re-charging.
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 bat-
tery to 50% 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.
