Introduction
This is a manual for the E-Move electric power assist unit for wheelchairs. Before you read this manual,
check which product you are using. For information on the wheelchair frame to which E-Move is attached,
see the owner’s manual from the frame manufacturer.
This product consists of the left and right drive units, battery and the battery charger. The drive units are
already installed to the wheelchair frame. For the initial use, the customer does not have to use tools,
and so on, to assemble the wheelchair. Refer to “2. Names of Parts” to ensure that these components
are installed to the wheelchair that you purchased and that the battery and charger are included. If you
visually notice that any of these components are not installed, are not included, or are damaged before
using the wheelchair, immediately contact the dealer without using the wheelchair.
E-Move
For information for operating the wheelchair frame and warranty for the frame with which you are using
the E-Move, see the frame manual.

Caution: Federal law restricts this device to sale by or on the order of a practitioner licensed by the law of
the State in which he/she practices.
1.1. Foreword
Thank you for purchasing the E-Move.
Indication for use: The device E-Move is a Powered Wheelchair Conversion Kit and suitable for a disabled
person who can’t walk or has restrictions on walking. It is intended for medical purposes to provide a means
for a disabled person to take over the propulsion of the wheelchair and increase mobility and exibility.
The device is intended for indoor and outdoor use.
Generally speaking, riding in a wheelchair incurs the possible risk of personal injury or damage to the
wheelchair from improper use. Depending on the type or extent of the disabilities of the user, it might be
dangerous to travel unaccompanied.
Before using the wheelchair, be sure that not only the user, but also the assistant and controller, has read
this manual to assure full understanding.
(1) The wheelchairs on which the E-Move has been installed are wheelchairs for physically handicapped
people, and legal status of someone in a wheelchair is that of a pedestrian. Make sure to adhere to
the tra󰀩c rules and manners of a pedestrian.
(2) The E-Move withstands a load of 130 kg (286 lb). Use with a total maximum load included the chair
frame weight of 130 kg (286 lb). If the frame on which the E-Move is installed has an even lighter
load capacity, ensure that you do not exceed that value.
(3) To help ensure safe use, warning labels are a󰀩xed to this product. Make sure to adhere to the warning
labels. Refer to “1.6. Warning Label Location Diagram” for the locations of the warning labels.
(4) Do not use this product for any purpose other than as an electric wheelchair.
(5) Some of the illustrations in this manual are images of general electric wheelchairs. The actual
product may be di󰀨erent than that shown.

WARNING
● Ifthereareanyobstacles,stopthewheelchairandcheckinfrontofyouandbehindyoufor
safety before proceeding.
● Whentravelingnearaditch,thetiremayfallintoitifthereisagapevenifitiscovered.
Have an assistant accompany you instead of traveling alone.
● Ifanoncomingvehicleisnear,stopthewheelchair,waitforthevehicletopass,andthen
check in front of you and behind you for safety before proceeding.
● Donotoperatethewheelchairoutdoorsatnight.
Not being able to see the road conditions, you
may lose balance and fall, or people or cars may
collide into you if they cannot recognize you.
● Ifitisrainingorsnowing,donotoperatethewheelchairoutdoors.Automobilesandother
vehicles may collide into you if they cannot recognize you. If it starts to rain or snow while
you are outdoors, move indoors as soon as possible.
WARNING
● Donotusethewheelchaironaslopesteeperthan
6 degree (10% grade). It may tip over or the brake
maybecomeine󰀨ective.
● Whengoingup/downaparticularslopeforthersttime,haveanassistantaccompanyyou
to ensure safety.
1.5.7. Operation on Slopes
The wheelchairs equipped with the E-Move are built to be lighter compared to other heavier
electric wheelchairs that use a general lead battery. For this reason, when a person sits in it,
the overall center of gravity shifts higher. Therefore, caution is necessary when traveling on a
slope.
Over 6°

1
12
WARNING
● Donotoperatethepowerswitchonaslope.
The wheelchair behaves as a normal wheelchair
whileswitchedo󰀨.Itmaystarttomove.
Park on a level place and apply the parking brake
when you operate the power switch.
● Donotabruptlyturnonadownhillslope.In
addition, do not traverse horizontally or diagonally
across a steep slope. You could easily lose
balance and tip over.
● Onadownhillslope,startthebrakingoperation
early. The braking distance on a downhill slope
may be significantly longer than when traveling
on level ground.
● Intheareaswherethewheelchairleanssharply
to the left or right, the wheelchair may tip over
sideway. Have an assistant accompany you.
● Whendescendingdownaslopewiththeassistant
operations, descend in reverse. If the assistant
moves the wheelchair forward when descending,
thepassengermayplungeforwardandfallo󰀨the
wheelchair.

13
1.5.8. Going Up/Down Curbs
The wheelchairs equipped with the E-Move are built to be lighter compared to other electric
wheelchairs that use a heavier general lead battery. For this reason, when a person sits in it,
the overall center of gravity may be different. Therefore, use caution when traveling on a curb.
● Whengoingup/downacurbforthefirsttime,haveanassistantaccompanyyouinsteadof
traveling alone.
● Whentravelinginpowerdrivemode,thewheelchaircanclearleveldifferencesofapprox-
imately 25 mm (1 inch) (varies depending on the caster size). Any greater level differences
should be cleared by an assistant by manual push operation.
WARNING
● Becausethefrontcastersaresmall,theyareabletotraveloveronlysmallcurbs.There-
fore, caution is necessary when traveling over curbs in power drive mode.
● Whentravelingoveracurb,becarefulnottoloseyourbalance.
● Whentravelingoveracurb,proceedatarightangletothecurb.Donottraversethecurb
diagonally.
● Whentravelingbetweenasidewalkandaroad,becarefulofcurbs.
● Whendescendingfromacurbwiththeassistantoperations,descendinreverse.Ifthe
assistant moves the wheelchair forward when descending, the passenger may plunge
forwardandfallo󰀨thewheelchair.
● Whengoingup/downacurbwiththeassistantoperations,thesafetywheelsoftheanti-tip
bar may be raised or folded temporarily depending on the height of the curb. After traveling
over the curb, be sure to place the safety wheels of the anti-tip bar in the correct position
before operating the wheelchair.
