5 Introduction
Before starting your journey, familiarise
yourself with these operating instructions paying particular attention to the safety information
and hazard warnings contained within them.
If you are not sure how to handle the
product or if technical faults occur, please contact your dealer or PRO ACTIV before using it.
When operating the product, the wheelchair operating instructions must also be observed. Information on limit values must not be
exceeded. If the values contained in the two
operating instructions differ, the lower limit is
the one which applies.
The control software is programmed at the
factory to ensure that the legal requirements
for a pedelec drive are met. If changing the
software, it must be ensured that these requirements are still met.
Never leave the product unattended, either when it is switched on or switched off. If
this cannot be avoided, removing the battery
and the display can help prevent unauthorised
use.
6 Product description / purpose
The product is attached to a manual wheelchair as an electrically propelled drive unit
which helps to assist the wheelchair user when
moving the wheelchair. This means that long
distances can be covered largely without tiring
the user. On flat roads and uphill, the electrical
drive of the product provides the force to pull
the wheelchair. Downhill, the speed can be
controlled using the product's braking system
and, possibly, through the recuperation. This
allows for safe driving down slopes.
For safety reasons, the product may only be
operated by persons who
• have been trained in its use by the dealer
or PRO ACTIV.
• can move and control their hands and
arms so that they are able to operate the
controls and perform the full steering
movement without restrictions while driving.
• are physically and mentally capable of
safely operating the device in all operating
situations and can meet the legal requirements for use on public roads.
7 Acceptable usage and operating
conditions / places of use
Observe the instructions on permitted operating conditions in the operating instructions of
your wheelchair on which the product has been
installed.
Use the product on paved surfaces. Avoid
driving on unpaved or loose surfaces (e.g. on
loose gravel, in sand, mud, snow, ice or
through deep puddles of water), as this may
result in incalculable risks.
The wheelchair with the adapted product must
be equipped in accordance with road traffic
regulations when operated on public roads and
spaces.
When driving downhill the maximum permitted
speed must not be exceeded; if necessary
operate the hydraulic service brake. The appropriate value for your product can be found
in the operating instructions from the drive
manufacturer.
The driving characteristics and speed parameters can be programmed using the display. The
programming has been done at the factory and
does not normally need to be adjusted.
Changes to the programming may only be
carried out by your dealer or PRO ACTIV.
The maximum permitted load of the product in
its standard design is 120 kg towed capacity
and 10 kg payload. Individual customisation
can be made to accommodate a higher load;
this will be indicated on the ratings plate.
Please ensure that the load limit indicated on
the ratings plate is not exceeded when transporting objects.
Operating instructions NJ1 e-assistant

It is recommended that you fit the wheelchair with an anti-roll back device and to activate this before driving on slopes. The anti-roll
back device can also be used if a wheelbase
extension is used on the wheelchair.
Figure 1: Anti-roll back device
8 Technical specifications
8.1 Drive system
The technical specifications, information and
instructions about the drive system can be
found in the operating instructions from the
drive's manufacturer which are included.
The range of the drive system varies depending on the terrain driven across and the prevailing driving conditions. With optimum driving
conditions (including maximum power transfer
of the user via the pedal crank, level ground,
fully charged batteries, ambient temperature of
20 °C, smooth driving, maximum tyre pressure,
no headwind), the range indicated in the drive
manufacturer's operating instructions can be
achieved.
A continuously adjustable speed of up to 6
km/h can be achieved using the pushing aid
without moving the crank. Motor support above
this speed is only done with manual rotation of
the pedal crank. Motor support is provided up
to a maximum speed of 24.9 km/h.
8.2 Climbing power
The climbing power refers to the ability of the
wheelchair-product combination to climb a
slope. This is very much dependent on the
weight distribution between the wheelchair
wheels and the product's drive wheel and on
the friction coefficient of the ground. Under
sub-optimal conditions, the drive wheel may
start to spin before the maximum climbing
power has been reached.
Maximum climbing power:
10° or 22%
The slope which can be driven up using the
product-wheelchair combination is also dependent on the manual driving force which the
driver can apply as well as the maximum
climbing power.
8.3 Product weight
The total weight depends on the drive system
and accessories and starts from 12.9 kg.
8.4 Load weight
Maximum load weight:
120 kg towing capacity and 10 kg payload
8.5 Obstacle height and turning circle
Maximum drive-over / negotiable obstacle
height: 10 cm (must be ensured through an
appropriate adapter assembly / setting, steering wheels must be removed ( recommended equipment of the wheelchair: steering
forks with quick-release axle))
Turning circle: approx. 2.3 m
8.6 Service life
The service life of the product is 6 years in
accordance with the medical products law.

9 Commissioning
The product is handed over to you ready to
use by a PRO ACTIV dealer. They will fit, if not
already done, the required fastening elements
to your wheelchair to hold the adapter and, if
required, any other accessories. In addition,
the batteries and the display included in delivery will be installed and the parking stands will
be adjusted to the correct height.
Finally, you will be fully instructed in the use of
the product based on the operating instructions
included in delivery. If you wish (recommended
by PRO ACTIV), you will be presented with a
record of training and a hand-over certificate
as written evidence and in addition the operating instructions and any other accessories for
your own use. The form for the record of training and the hand-over certificate can be found
in chapters 30 and 31.
It is recommended that you take along an assistant to the training so that, if required, they
can assist you later when handling the product.
During the initial commissioning of the product,
drive at minimum speed and become accustomed to the driving characteristics of the
product. Always adapt the speed and driving
manoeuvres to match your own abilities, the
external circumstances and the legal regulations. You will get a feel for how to use the
product safely after a short time.
10 Hand-over
The hand-over must be done by your dealer or
a field representative from PRO ACTIV. During
the hand-over, the record of training (chapter
30) and the hand-over certificate including the
associated check list (chapter 31) must be
filled in. The dealer should send a copy of the
completed documents to PRO ACTIV for filing
either as a scanned file via e-mail, by fax or in
the post. These documents are available as
pdf files which can be completed in the
download area at www.proactiv-gmbh.com
.
11 Safety instructions - prior to
driving / use
The operating instructions of the connected wheelchair must be strictly observed
when using the product.
If your wheelchair is operated in combination with the product, any existing anti-tipping
supports must be put into their passive position
or removed (see the wheelchair's operating
instructions). If the wheelchair is then used
without the product, the anti-tipping supports
must be brought back into their operating position again to ensure tipping stability.
Before every trip, check the condition of
the wheels (e.g. visual inspection of the spokes
and rims, check the tyres for damage, foreign
bodies and crack formation). If you have any
doubts, the wheelchair-product combination
must not be operated any further.
Before starting your trip check that the
product's brake functions. If all existing brakes
are not fully functional, no trips may be taken.
Before every trip, check that the product is
firmly attached to the adapter and that the
adapter is firmly attached to the wheelchair.
The product may not be operated on the
wheelchair if any of the connections are not
tight and secure. In this case, contact your
dealer or PRO ACTIV.
Always ensure that your feet cannot slip
off the feet plate of the wheelchair when using
the product, if necessary by using a special
fixation device.
If present, check the function of the front
and rear lights as well as the effectiveness of
the side and rear reflectors before every trip.
Lights and reflectors must be clearly visible
during the journey and must not be covered by
other objects.
Operating instructions NJ1 e-assistant
7
Check tyre pressures at regular intervals.
Ensure that you comply with the manufacturer's specifications which are fitted to the
tyres. Tyre pressure which is too low has a
detrimental effect on the driving behaviour, the
range of the product and the braking action.
It is recommended that you only take a
trip with completely charged batteries. If this
recommendation is not followed, you must take
into account that the range will be restricted
when planning your route.
To minimise the risk of suffering serious
head injuries in the event of a fall, a helmet
should always be worn when driving with the
product.
12 Safety instructions - while driv-
ing / using
Always hold onto the crank handles with
both hands while driving. If the driving situation
requires you to take one hand off the crank
handles, this is only permitted when the speed
has been reduced to the minimum possible
beforehand.
Before driving up or down slopes or hills
with the product, you should be proficient in the
safe handling of the product on the flat.
Increase the speed slowly up to the desired speed.
Use particular caution when approaching
stairs, edges, drops or other hazard areas.
When driving round a bend, reduce your
speed to a minimum.
When the product is switched on, the
smallest movement on the crank handle is
converted into a drive command. When waiting
at potential hazard areas (e.g. while waiting at
a pedestrian crossing, on hills or slopes or at
ramps of any type), always hold down the service brakes and keep the crank handles in a
vertical position downwards.
In rooms, tight or dangerous areas or
when manoeuvring, the product may only be
used with the drive inactive and turned off to
prevent unintentional drive signals. Due to the
increased turning circle, it can be difficult to
turn in buildings, in front of or in lifts or other
buildings, as the standard in such buildings
assumes a maximum turning circle of 1.5 m.
During long trips the drive and the brakes
of the product may heat up. Therefore, do not
touch the drive or the brakes during or immediately after the trip (e.g. when detaching or
loading the product).
Do not attach objects (carrier bags, etc.)
to the product. These could cause an unwanted drive impulse when stationary and
prevent safe operation of the product while
driving.
When driving on areas which are used for
pedestrians, observe the maximum permitted
speed (walking speed 6 km/h) and keep a
sufficient distance (at least the width of a
wheelchair) from the kerbs or other obstacles
and other road users.
When driving on public roads and footpaths, the provisions of the road traffic regulations must be observed.
Avoid driving on unpaved or loose surfaces (e.g. on loose gravel, in sand, mud,
snow, ice or through deep puddles of water).
If you encounter new driving situations
which are unknown to you, approach them with
great care. If you consider that the risk is too
high, you must immediately abort the driving
manoeuvre and, if required, call for help to
assist you in extracting yourself from this situation.
You must not make telephone calls while
driving. You should also avoid driving near to
strong electrical interference fields.
Operating instructions NJ1 e-assistant
8
The driving characteristics of the product
can be influenced by electromagnetic fields
which can be produced by mobile phones or
other radiating devices. The power supply to
the product should be switched off when operating such devices.
Operating the product can affect other
devices, for example theft protection barriers in
department stores.
By performing regular checks, ensure that
the safety bolts of the adapter are always in
the correct position while driving (see operating
instructions "Adapter & Adaptation").
During a trip never jerk the handlebars to
the left or the right, as this may cause the
wheelchair-product combination to tip over
sideways in certain circumstances.
Never turn the product off on upwards or
downwards slopes. This could result in dangerous situations to which you can only react
with a delay in terms of electrical assistance or
virtually not at all by manual means.
Never drive parallel to slopes.
While driving, never grab onto the wheelchair wheels, in the area of the product wheel
or into other rotating parts; if you do you may
cause injuries.
Only brake the product using the service
brakes.
The product is only designed to be used
to transport persons with limited mobility and
must not be used for any other purpose, e.g.
by playing children or to transport goods.
You may only drive on slopes where the
wheelchair-product combination can be safely
controlled by steering and braking of the product.
If the weight load on the drive wheel falls
(e.g. when driving on slopes) or when driving
on loose / slippery surfaces, the braking action
of the wheel may be considerably reduced.
The driving style and speed should be adjusted
so that the product can be safely stopped at all
times using the brakes.
Towing or using a trailer is not permitted.
If the situation allows it, the speed should
be reduced by carefully applying the service
brake. Abrupt braking can cause the upper
body to fall forwards which can thereby result
in injuries or loss of vehicle control.
13 Safety instructions regarding
obstacles
Obstacles like curbs, for example, should
always be negotiated driving forwards and
always using the minimum speed required.
The maximum obstacle height which can
be negotiated is 10 cm. This value can, however, be reduced due to the specifications of
the type of wheelchair or its settings. Therefore, you should observe the values given in
the wheelchair's operating instructions or the
restrictions dependent on the settings.
When driving over or passing obstacles,
you must absolutely avoid any wheelchair or
body parts becoming trapped on the obstacle.
This could result in falls, serious injuries to the
user or third-parties as well as damage to the
product and the wheelchair.
Always drive over curbs or other obstacles
so that you cross them to the front or at right
angles. If you drive at them on an angle, or
only have one rear wheel on the obstacle,
there is an increased risk of tipping over to the
side which can result in serious injuries to the
user and third-parties as well as damage to the
product and the wheelchair.

14 Safety instructions regarding
dangerous locations and dangerous situations
The operator of the product determines the
route to be driven taking the operating instructions, their driving knowledge and physical
abilities into consideration.
The personal driving skills are particularly important in the following dangerous locations
which are provided as examples; the product's
user must use their judgement before driving in
such locations:
quay walls, landing and berthing locations,
paths and locations close to water, unsecured bridges and dykes.
narrow paths, slopes (e.g. ramps and
driveways), narrow paths on a slope,
mountainous routes.
narrow and / or steeply sloping paths along
main roads or near cliffs.
routes which are covered in leaves, snow
or ice.
ramps and lifting equipment on vehicles.
When driving in a circle or turning on hills
or downward slopes, there may be an increased tendency to tip over to the side due to
the changes in the centre of gravity. Always
perform these driving manoeuvres with increased caution and only at slow speed. If
required, the driving manoeuvre must not be
performed or only with the help of an assistant.
When crossing main roads, intersections
and level crossings, extreme caution is
needed. Crossing rails in the road or at level
crossings must never be undertaken while
driving parallel, otherwise the wheels could
become caught which would result in the
wheelchair and the product being unable to
manoeuvre.
When driving on ramps and lifting equipment on vehicles, extreme caution is needed.
During the lifting or lowering operation of the
ramp or the lifting equipment, the product
should be switched off and the service brake
operated. In this way rolling away due to unintentional drive commands, for example, can be
prevented.
The grip of the tyres on the ground is reduced in the wet. There is an increased risk of
slipping. Adjust your driving, braking and steering behaviour accordingly.
15 Ending the driving operation
Turn off the drive unit. To make getting out of
the wheelchair more simple, the product can
be disconnected from the wheelchair (see
operating instructions "Adapter & Adaptation").
The product may only be disconnected with the
drive turned off to prevent any unintended
drive signals.
16 Safety instructions - after driv-
ing / use
Always turn off the product immediately
when it is not in use to prevent accidental triggering of a drive signal by touching the crank
handle and to prevent the batteries being discharged.
Always observe the instructions and recommendations in the drive manufacturer's
operating instructions concerning charging the
batteries.
17 Adapter & adaptation
Where necessary and ordered, a suitable
adapter for your wheelchair is included with the
delivery.
Please read the operating instructions and
assembly instructions for the "Adapter & Adaptation" before using the product.
The drive's controller must only be
switched on after completing the adaptation
process. The adaptation and disconnection of
the product may only be performed when the
driving signal sensor is inactive to prevent
unintended drive signals.

The product may only be adapted and
detached on dry, stable and flat surfaces.
18 Functional elements
18.1 Parking stand
18.1.1 Active and passive positions

Figure 4: Parking stand in the passive position
18.1.2 Parking stand height adjustment
It is important to adjust the height of the parking stand to bring the adapter into the right
position in relation to the product's docking
plate. Height adjustment is made by loosening
the M6 oval head screw (SW 4 mm) and adjusting the position of the adjustment inlet.
Finally, tighten the oval head screw up to 7 Nm
of torque.

18.2 Pedal bearing support & crank
18.2.1 Seating position
The seating position and therefore the pedal
position and the pedal crank length depend on
the upper-body stability or the core musculature. A suitable adjustment to the arm length
will have been made during the consultation /
measurement procedure.
With weak core musculature, the seating
position should normally be chosen so that the
upper body remains still in an upright position
when operating the crank while driving. This is
particularly important if you have low seating
stability due to missing or weak core musculature. A rocking motion (forwards and backwards) of the upper body or the head should
be avoided where possible. The height of the
pedal bearing in this case is selected to be
slightly higher (chest height or higher).
Sporty drivers with the appropriate trunk
stability relieve their arm musculature by mov-
ing their trunk at the same time. The height of
the pedal bearing in this case can be selected
to be slightly lower (chest height or lower).
Figure 6: Elbows are not completely straight, upper
body is in an upright position
Figure 7: Distance between the crank and the thigh /
knee
The cranks must not touch the knee or
thigh when they are being turned.
The elbows must not be completely extended when the crank handles point completely forward away from the body.
A suitable restraint system must be used if
you have poor seating stability due to a lack of
or weak core musculature. The selection of the
suitable system must be made in conjunction
with your doctor or therapist and / or defined
and implemented by your dealer. There are
various systems available such as chest straps
or four-point safety belts. Also, the dealer can
frequently individually make a system or adapt
one that has been purchased.
18.2.2 Pedal bearing position
In a product equipped with a non-adjustable
pedal bearing support, a subsequent adjust-
ment of the pedal bearing position can only be
achieved by exchanging the pedal bearing
support, the angle adjustment possible on the
steering head as well as the length adjustment
and the spacing of the adapter tube on the
adaptation points on the wheelchair frame (see
operating instructions "Adapter & Adaptation").
The pedal bearing support can be exchanged
by loosening the four M6 fastening screws (SW
5 mm) on the tip fork bridge and the four M6
fastening screws (SW 4 mm) on the pedal
bearing housing. Then the new pedal bearing
support with another length can be inserted
and the 8 fastening screws tightened up to 7
Nm and secured with thread lock fluid. Finally,
