Introduction
This manual contains servicing instructions for the Mini Crosser
X1 mobility scooter.
The Service Manual is a supplement to our Spare Parts Cata-
logue and User Manual.
You have now taken possession of an electric mobility Mini
Crosser developed for outdoor driving by active users. It is what
is called a Class C vehicle in according to the European classi-
cation of electric wheelchairs.
The Mini Crosser X1 is designed for safe travel for at least 10
years, up to a max. of 5,000 hours, providing it has service and
safety inspections every third year, which is equivalent to around
1500 operating hours. The service must be carried out either by
Medema A/S or an authorised workshop.
IMPORTANT! For safety reasons it is of the utmost importance
that the servicing 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 re.
If help is required with troubleshooting, Medema is always happy to
provide telephone assistance. If the problem seems to be an elec-
trical fault that prevents the scooter from working, please tell us the
error code. This can be found on the battery indicator on the control
panel. Read more about this in the section on Troubleshooting.
Please also have the scooter’s serial number handy when con-
tacting Medema A/S.

manual, you are always welcome to contact us at:

Symbols
Used in the manual to indicate sections describing situations
where extra care is required owing to the risk of personal injury.

Warning!
For safety reasons the vehicle must not be lent to persons who
are not completely familiar with it. The vehicle is designed for
one person only.

max. 175 kg. Can be supplied in a HD version as standard for a

Contagion!
A standard Mini Crosser is equipped with tyres that does not
contage, but if another type of tyres are used, it can sometimes
rub off on oor coverings, particularly linoleum. Medema A/S
assumes no responsibility in case of contagion.
To prevent this, we recommend that you protect delicate oors
with some sort of driving surface.

Safe servicing
• To avoid injuries to both the service engineer and the subsequent
user of the scooter, it is important to get to know the product be-
fore servicing it.
• Be particularly aware of the following:
• The Mini Crosser MUST be turned off at the main switch. If elec-
trical components are being serviced, the positive terminal on the
battery MUST also be disconnected.
• If the voltage needs to be measured in the course of troubleshoot-
ing, take great care not to short-circuit anything.
• Take great care not to short-circuit the battery terminals.
• Be careful not to lift heavy parts such as the seat, battery and
motor gear incorrectly or drop them.
• Make sure to raise one rear wheel off the ground so that the
scooter cannot drive off accidentally.
• Use professionally maintained tools.
• Where lock nuts are used, NEW ones MUST be tted when the
scooter is reassembled.
• Take care to t new cable strips in the same way as the old ones.
Make sure that no cables can be trapped by moving parts or stick
out in such a way as to catch on things.
• End every service by making sure that the product is roadworthy:
- Check that all the connectors are plugged in correctly.
- Check that all the mechanical parts are properly secured.
• Turn the scooter on and check
- that the magnetic brake clicks when the accelerator is activated.
- When the accelerator is released, it must not be possible to
push the scooter.

Storage
The Mini Crosser is designed for use in all types of weather.
The scooter should, however, be stored and charged under cov-
er at temperatures in excess of 0°C. The charger must also be
kept dry.
If the scooter is not going to be used for a long time, it is advis-
able to protect the tyres by chocking the scooter up. It is also a
good idea to cover the scooter to protect it from dirt, dust and
sunlight.
Cleaning
The Mini Crosser should be cleaned with a damp cloth. A little
washing-up liquid can be used if necessary. The plastic covers
can be polished with an ordinary glass cleaner or car wax.

Designation Description
Key switch To start the vehicle:
Turn the key to driving position (1) When the Mini Crosser is
turned on, the control system performs a safety check of the
electrical system. The check lasts half a second. If the accelera-
tor is operated during this time, the Mini Crosser will not be able
to move until you have turned the key to 0 and back to 1.
Speed selector The tortoise in minimum position indicates the lowest speed
range. 0-6 km/h
The hare in maximum position indicates the highest speed
range. Up to 15 km/h
Battery indicator Lights up when the key is turned. Indicates, after half a second,
the battery charge level. It gives a more precise indication after
approx. 1 minute of driving. When the red, amber and green
sections are lit, the batteries are fully charged. When the indi-
cator is at the bottom of the amber section, the batteries should
be charged as soon as possible. If only the red section is lit or
ashing, the batteries must be charged immediately.
Hand brake Acts on the rear wheel and should only be used as an extra /
emergency brake and parking brake. It can be secured in
locked position.
Accelerator
(See picture
below)
Activate the arm at the front slowly and the Mini Crosser will
start to move forwards. The more the arm is pressed, the faster
the Mini Crosser will move. When the arm is released, it will
ip back to starting position of its own accord and the Mini
Crosser will stop. Activating the rear arm will cause the Mini
Crosser to reverse. The magnetic brake on the rear wheels will
engage when the Mini Crosser is stationary and is equivalent
to the parking brake on a car. The accelerator can also be used
to control speed downhill. In this case the motor will act as a
brake.
Light switch Turns on the front and rear lights. The key switch must be in
position 1 (driving position).
Hazard warning
lights
Turns on all the indicator lights at once. Also works when the
key is removed or turned to position 0 (stop position).
Indicator switch Left arrow: indicator, left-hand side. Right arrow: indicator, right-
hand side. Activate the same switch to turn the indicators off.
Horn Powerful electric horn. Press the horn switch to activate.
Charging socket Turn off the key switch during charging. Please note that it is
not possible to drive the Mini Crosser while the batteries are
charging. See also the section entitled “Batteries and charging”.
Accelerator back (thumb control)
Accelerator (four-nger control)
The accelerator forward and backwards
are physically connected, which means
that when one or the other is activated,
the other will move the opposite way.
Warning!
When the handlebar is moved closer to
your body, there is a risk for the leg to
touch the accelerator by mistake.

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.
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.
