Troubleshooting

If a system trip occurs, you can find out what has happened by counting the number of LEDs on the battery gauge that are flashing.
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 charging 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 center position 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.
7 LED+ S| A communication fault is indicated. Make sure that the joystick cable is securely connected and not damaged.

Charging

Charging
1| Plug the cable into the control box on the wheelchair
2| Plug the charger into the outlet or switch it on
3| Use the indicator lights on the charger to check that charging has started.
4| When charging has finished, switch off or unplug the charger, and then remove the

charger cable from the control box.

You are recommended to charge the batteries every night after you have used the wheelchair. (Further information in the User Manual)

Note:

If the batteries are damaged or are leaking, you should avoid touching them because you may burn yourself.
Contact a qualified workshop immediately!
Old batteries must be delivered to an approved facility for safe disposal.
Further information is in the User Manual.

Driving the MC 1144

Before getting on or off the vehicle, you must check the following:

That the wheelchair is switched off and that it is not disengaged.
That the wheelchair and the seat you are moving to are both stable.
Avoid placing your full body weight on the footrests. This may tip the wheelchair forward.
While driving, you must place your arms on the armrests and your feet on the footrests.
Cables and leads must be fixed using ties.
Never attempt to climb onto raised objects or curbs 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 curbs. The higher the seat is raised, the more unstable the chair becomes.

Note:

If your MC/vehicle is fitted with a docking system from Dahl Engineering, note that the clearance changes from 9 cm to 7.5 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 1144:

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 (flat) surface.
Avoid driving off-road.
Avoid driving on icy surfaces, or smooth surfaces (for example snow or freshly mown grass).
Never attempt to climb curbs higher than 7 cm. If the wheelchair has a docking system, the clearance is reduced from 9 cm to 7,5 cm.
Avoid driving over curbs diagonally. There is a risk of tipping over.
Not to be used for towing other vehicles, etc.

Note:
It is forbidden to drive MC 1144 while intoxicated. 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 continuing to drive, there may be a danger of fire or vital parts being destroyed.

Driving on public roads

When driving on public roads, footpaths, pedestrian streets, car parks, shopping centers, etc. you must make sure you adjust your speed and distance for other users. At 7 km/h you must follow the traffic rules applicable 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 regarded 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 1144 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 1144 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 first, after which the MC 1144 can be driven as described above.

Note!
You must NEVER brake the MC 1144 by switching off the I/O button while moving, as this applies the magnetic brake with considerable force, with a resulting risk of tipping.

Disengagement:
The MC 1144 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. Before an occupant is left unattended or attempts to operate the wheelchair, make sure that the disengagement handles are placed in (a 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.

Safety check

See the User Manual

Serial number

All wheelchairs have a serial number plate showing the year of production, month, and serial number. The same serial number can also be found on the front of the User Manual.
Please quote the serial number when making inquiries about servicing, spare parts, etc.

Serious incidents

Any serious incident that occurs in relation to the device/Mini Crosser should be reported to the manufacturer and the competent authority of the Member State in which the user and/or patient is established.
