Trouble shooting
If a system trip occurs, you can nd out what has happened by counting
the number of LEDs on the battery gauge that are ashing.
Below is a list of self-help actions. Try to use this list before you contact
your service agent.
LED Meaning
1 LED The battery needs charging or there is a bad connection to the battery.
Check the connections to the battery. If the connections are good, try charg-
ing the battery.
2 LED The left hand motor has a bad connection. Check the connections to the left
hand motor.
3 LED The left hand motor has a short circuit to a battery connection. Contact your
service agent.
4 LED The right hand motor has a bad connection. Check the connections to the
right hand motor.
5 LED The right hand motor has a short circuit to a battery connection. Contact
your service agent.
6 LED The wheelchair is being prevented from driving by an external signal. The
exact cause will depend on the type of wheelchair you have.
7 LED A joystick fault is indicated. Make sure that the joystick is in the centre posi-
tion before switching on the control system.
8 LED A possible control system fault is indicated. Make sure that all connections
are secure.
9 LED The parking brakes have a bad connection. Check the parking brake and
motor connections. Make sure the control system connections are secure.
10 LED An excessive voltage has been applied to the control system. This is usually
caused by a poor battery connection. Check the battery connections.

Driving the MC 1124
Before getting on or o󰀨 the vehicle, you must check the following:
A. That the wheelchair is switched o󰀨 and that it is not disengaged.
B. That the wheelchair and the seat you are moving to are both stable.
C. Avoid placing your full body weight on the footrests. This may tip
the wheelchair forwards.
While driving, you must place your arms on the armrests and your feet on
the footrests.
Cables and leads must be xed using ties.
Never attempt to climb onto raised objects or kerbs higher than 7 cm, and
always approach changes of level head on, with the front and back wheels
moving in a straight line.
Warning!
The seat should NEVER be hoisted while driving on uneven surfaces,
slopes or up and down kerbs. The higher the seat is raised, the more un-
stable the chair becomes.
Note:
If your MC/vehicle is tted with a docking system from Dahl
Engineering, note that the clearance changes to
5.5 cm.
See the User Manual for details about driving on hills, inclines and declines,
and driving on public roads.

10 tips for driving the MC 1124:
• Reduce the speed when turning corners and also when going downhill.
• Reduce the speed when driving on inclines. Max. incline = 6° = 10%
• Reduce the speed when driving on a sideways incline.
Max. sideways incline = 6°
• Avoid parking on snow and ice.
• Always park on a level (at) surface.
• Avoid driving o󰀨-road.
• Avoid driving on icy surfaces, or smooth surfaces (for example snow or freshly
mown grass).
• Never attempt to climb kerbs higher than 7 cm. If the wheelchair has a docking
system, the clearance is reduced to 5,5 cm.
• Avoiding driving over kerbs diagonally. There is a risk of tipping over.
• Not to be used for towing other vehicles, etc.
Note:
Do not drive the MC 1124 when under the inuence. This applies to both
medicine and alcohol.
Warning!
If the vehicle behaves abnormally in any way - makes noises, smells burnt,
etc. - stop the vehicle immediately and seek technical assistance. By con-
tinuing to drive, there may be danger of re or that vital parts are destroyed.

Driving on public roads:
When driving on public roads, footpaths, pedestrian streets, car parks,
shopping centres, etc. you must make sure you adjust your speed and
distance for other users. At 7 km/h you must follow the tra󰀩c rules applica-
ble to cyclists. This also means that your lights must be switched on during
lighting-up time. (Optional extra)
On footpaths, the maximum speed is 6 km/h. In this situation you are re-
garded as a pedestrian.
Note:
You should assume that other road users cannot see you while you are
sitting in the MC. So take great care and wait for the road to clear before
crossing.
Driving on stairs/escalators:
The wheelchair is not designed for use on stairs or escalators and any
attempt to do so may cause serious injury to yourself and others.

Brakes
The MC 1124 is equipped with two sets of brakes: The motor brake and the
parking brake.
Motor braking:
When you drive downhill, the control unit of the MC 1124 applies the motor
brake.
Parking brake:
When the vehicle is stationary and the joystick is not moved, a magnetic
brake is automatically applied to each drive unit. For driving, the magnetic
brake is released rst, after which the MC 1124 can be driven as described
above.
Note!
You must NEVER brake the MC 1124 by switching o󰀨 with the I/O button
while moving, as this applies the magnetic brake with considerable force,
with a resulting risk of tipping.
Disengagement:
The MC 1124 is equipped with two disengagement levers: One on each
side of the vehicle.
ALWAYS disengage on both sides.
Warning!
When the wheelchair is disengaged, the braking system is deactivated. Be-
fore an occupant is left unattended or attempts to operate the wheelchair,
make sure that the disengagement handles are placed in (normal position
for driving), which means it’s connected (the chair can not be pushed).
You must NEVER disengage on sloping terrain. This can lead to serious
damage or personal injury.
