Introduction
Congratulations on your new Mini Crosser MJoy electric
mobility scooter.
You have now taken possession of an electric mobility scooter
developed for outdoor driving by active users. It is what is
called a Class C vehicle in accordance with the European
classification of electric scooters.
For optimum enjoyment of this vehicle - and to avoid
breakdowns and accidents - we recommend that you read this
User Manual carefully. As a new user, you should pay particular
attention to the section entitled “Driving the Mini Crosser MJoy”.
The Mini Crosser M Joy is designed for safe travel for at least 10
years, up to a max. of 5,000 hours, provided it is serviced and
safety-checked every year, corresponding to 500 hours of operation.
The service must be carried out by an authorised workshop.
IMPORTANT! For safety reasons it is of the utmost importance
that service and safety check intervals are complied with, as
this minimises the risk of brake failure and short-circuits in the
wiring, which could generate heat and cause a fire.

MJoy that can make everyday life easier for you. You are
always welcome to contact us for further information on special
accessories and adaptations.

form of a small magnetic key that comes with a keychain.
Keep magnetic key to the key icon on the joystick, you will hear
a signal, and after a few seconds the scooter can not run. Turn
the scooter on now (I / O button), a single red lamp is lit. When
you want to use the scooter again, hold the magnetic key back
to the key symbol, and now you can drive again.
Should you lose the magnetic key, any magnet can be used.

Safety check Joystick
Daily safety check:
The electronic system has an integrated safety check which
runs up to 100 times per minute. To supplement this check, you
should carry out the following regular checks.
• Switch off the electronic system (no lights in the display)
• Check if the joystick is bent
• Check if the joystick is damaged in any other way
• Check that it returns to the central position when you release it
If the check reveals any problems, contact a competent service
engineer before using the scooter again.
Weekly safety check:
Parking brake: This test must be carried out on a flat surface
with at least one metre of free space around the scooter.
• Start the scooter and slowly move the joystick forward. There is a
clicking sound. (The scooter may start to move in this setting).
• Immediately release the joystick and listen for the clicking sound,
which should occur within one second.
Repeat in all directions.
• Check that the rubber bellows around the joystick is intact. This
is important, as the bellows prevent moisture getting into the
electronic system.
• Check that the control box is properly secured.
If the check reveals any problems, contact a competent service
engineer before using the scooter again.
Monthly check
Check the tyre pressure at least once a month. It should be 2.8
bar.

General care and maintenance
A Mini Crosser M Joy does not require much maintenance. It
should be kept in a generally good condition, however. The
following should be checked regularly:
• Tyre pressure (if pneumatic tyres are fitted)
• Tyre wear
• Keep the control panel, the charging socket and the electronics
box under the seat dry.
• Battery charging
Never wash the Mini Crosser with a high-pressure cleaner
or direct water jet! This could damage the Mini Crosser’s
electronics.
To keep the Mini Crosser in good condition safety-wise, we
recommend the following regular checks:
Daily:
• Test the indicators and driving lights before using the Mini Crosser
in the dark or poor visibility.
Every three months:
Test the brakes and motor disengagement
With the disengagement lever up, it must not be possible to
push the Mini Crosser.
Test the brake disengagement function
When the brake disengagement lever is down, the battery
indicator should flash to show an error if the Mini Crosser is
turned on. In this case the Mini Crosser must not be able to
move when the joystick is activated.
Test the handbrake.
Apply the handbrake for a couple of seconds at low speed. This
will ensure that the lever arm and brake shoes do not seize up.
Lubricate the lever arm on the brake hub with acid-free oil - left-
hand rear wheel.

(More information in the service manual).
Insurance
In the eyes of the law a Mini Crosser M Joy with a maximum
speed of 10 km/h is a cycle, so separate insurance is not
required.
Most contents/home insurance policies include third-party
liability insurance for cyclists and so also cover Mini Crosser M
Joy users.
We recommend that you talk to your insurance company about
this when the vehicle is delivered. If necessary, comprehensive
insurance will have to be taken out separately.

Seat rotation
Pull the release lever back. The seat can be rotated 90° to
either side. When the lever is released, it engages with the seat
and holds it in place at 45° intervals.
Other seats that can be supplied for the Mini Crosser work on
similar principles. The release lever is normally mounted on the
right, but can be put on the left if so wished.
IMPORTANT!
The Mini Crosser is most stable when the seat is in its lowest
position. Always drive carefully when the seat is raised. Never
use the seat adjustment when driving on an uneven surface or
in hilly terrain.
Take extra care when lowering the seat on a Mini Crosser using
electric seat adjustment. Make sure that nothing is trapped in
the space between the seat and the chassis.
Avoid trapping anything when lowering the seat.
Release lever for seat rotation. Release lever for seat forward/back.

Driving the Mini Crosser M Joy
Getting in and out
It is important to learn a safe technique for getting in and out of
the Mini Crosser.
In general the following method should be followed:
• Make sure that the Mini Crosser M Joy is off (switch turned to 0)
• Make sure that the brake is on. (Lever for disengaging motor in
top position.)
• If necessary, turn the seat through 45° or 90° and make sure that
it is locked in position (clicked into place).
• If necessary, raise the armrest.
For some users the assistance of an attendant can be
recommended. The attendant should:
• Take care not to injure him/herself when lifting/lowering/supporting
the user.
• Make sure that the Mini Crosser is stable and unable to move.
Turn off the Mini Crosser and check that the brake is on and the
seat has been rotated until it clicks into place at either 45° or 90°.
• Make sure that the seat the user is being moved to is stable.
Turn the Mini Crosser off, rotate the seat
and raise the armrest.

User guide P9-0158-B 18 of 48 Version 1.0.2/2011
Medema Production A/S
Braking systems
There are three braking systems on the Mini Crosser:
• Motor brake - adjusts vehicle speed also when going downhill.
• Magnetic brake - the magnetic brake is automatic and engages
when the Mini Crosser stops. In an emergency, the Mini
Crosser can be stopped instantaneously by turning of the
joystick. Please note that this will cause very sharp braking.
The rear wheels will lock.
Must NOT be used in the normal course of driving.
The brake must never be disengaged mechanically using the
disengagement lever on a slope. This function is only designed
for use when pushing the Mini Crosser on a flat road.
• Handbrake - intended as an emergency brake and parking
brake. It must be operated with caution when driving in
slippery conditions and downhill.
General safety advice
Make sure that the backrest is upright and the seat is as low as
possible.
Positioning belts are recommended if the user is unable to
maintain a good driving posture independently.
Adjust your driving to road conditions. Take account of light,
traffic and weather. Be particularly careful when driving in the
dark or in bad weather, such as rain or snow. Avoid driving on
gradients with poor surfaces, such as: snow, ice, new-mown
grass, wet grass and wet leaves.
Never drive when under the influence. This applies not only to
alcohol, but also to drugs and medicines.
When using the handbrake as a parking
brake, lock it in braking position by
pressing the button in while applying the
brake.
To release the brake, press the button
again.

User guide P9-0158-B 19 of 48 Version 1.0.2/2012
Medema Production A/S
Reduce speed immediately if you feel you are losing control.
Always use the indicators when changing direction.
Check that lights and indicators are working before driving off.
Use your lights when driving after lighting-up time.
ALWAYS switch the scooter off when it is not in use. I/O button.
Driving
Even though the Mini Crosser is very stable, it can tip over.
Avoid sudden changes of speed and direction when travelling at
high speed, on poor surfaces and, not least, on slopes.
For short distances the Mini Crosser can drive up steeper
gradients than it has been tested as dynamically stable for. The
same applies to driving down such gradients. In such cases
there is an increased risk of the Mini Crosser tilting and even
tipping over. So be extra careful in following the driving tips
given below.
Anti-tilt wheels are recommended for driving in very hilly terrain.
(Optional extra)
New users are urged to practise the following in an area where
there is no other traffic:
• Set the Mini Crosser to low speed. Drive forwards and backwards.
Gradually turn the speed selector up and feel the change in the
speed of the Mini Crosser.
• Practise starting and braking. Get used to the Mini Crosser’s
response time.
• Practise driving in a narrow space, similar to inside a shop or
through a door.
• Practise turning, and get a sense of how much space is required.
Always drive slowly when turning. Practise reversing too.
• Practise cornering and driving over obstacles and on slopes.

User guide P9-0158-B 20 of 48 Version 1.0.2/2011
Medema Production A/S
Always drive straight up/down kerbs and ramps. Never at an
angle. See the illustrations on the following pages.
• Try braking at different speeds and notice the stopping distances.
• If possible, try driving on different surfaces (road, grass and
gravel).
• Practise assessing how far you can drive on a single battery
charge. Note how quickly the battery indicator changes from
green to amber to red.
Note!
The driving distance of the scooter will be reduced when driving
in hilly districts, into a head wind, in cold weather and with low
tyre pressure.
Traffic regulations
The traffic legislation for scooters varies from country to
country. Before starting to use the vehicle outdoors, it is the
user’s responsibility to familiarise him/herself with the relevant
legislation.
The following rules apply in Denmark:
Mobility vehicles such as the Mini Crosser with a maximum
speed of up to 10 km/h count as cycles in traffic legislation and
the traffic regulations for cycles must be followed at speeds in
excess of 6 km/h.
At speeds of up to 6 km/h the Mini Crosser is regarded as a
“pedestrian”, and it is permissible to travel on the pavement at
this speed. “Tortoise” speed corresponds to approx. 6 km/h.
Lights must only be used during lighting-up time. Crash helmet
and seat belts are not compulsory.
