3. Safety instructions and hazard information when using the e-fix
3.1 General instructions

Prior to commencing your trip, check that the parking brakes are fitted to your wheelchair and that they have been adjusted to the e-fix 
wheels. In doing so, you prevent your wheelchair from rolling away inadvertently in push mode. If there are no parking brakes adjusted to 
the e-fix wheels fitted to your wheelchair, your wheelchair must not be used. In order to fit parking brakes and adjust them to the e-fix 
wheels, please contact your authorised specialist dealer.

The e-fix wheels are controlled via the control unit joystick (see chapter 5.2.3). If the system is switched on, each actuation of the joy-
stick is converted into a travel command. This relates to moving both forwards and backwards as well as accelerating and braking. For this 
reason, switch off the control unit in the event of a prolonged standstill, in order to prevent the wheelchair rolling away inadvertently due 
to touching the joystick accidentally.

We recommend that you have a brief user training session when you first receive your e-fix. This will allow you to get used to the drive and 
everything you can do with it.

3.2 Information about user training

•

The safety and well-being of the user is the top priority. To ensure this, it is essential to understand the e-fix’s travel characteristics. 
Your specialist dealer or Alber agent will help you in this regard with a complimentary device training session.

•

Observe the information, safety instructions and hazard information provided by your wheelchair manufacturer. This also applies to 
using the e-fix.

•

Start your first driving attempts with caution and start your user training on level ground.

•

Take your user training in areas without any obstacles.

•

Always adapt your speed to external conditions so that you are able to stop your wheelchair or circumvent any obstacles that may sud-
denly appear, for example.

•

Never immediately push the joystick to its maximum position when starting off. This may result in the wheelchair moving uncontrollably 
(risk of accident).

•

Move the joystick gently and without sudden movements. Avoid suddenly moving the joystick to its maximum position, especially in 
potentially hazardous situations that you wish to avoid. Brake the e-fix carefully in advance until it stops.

•

When the joystick is released, your wheelchair will be braked gently. If you need to brake suddenly (immediate stop) then deflect the 
joystick briefly in the opposite direction to which you are travelling and then release it.

•

Only brake the e-fix using the joystick control unit. In this regard, never grip the tyres 

or the coupling ring [7] “for support”.

•

Before using the e-fix to navigate uphill or downhill gradients, you should be able to operate the device safely on level ground.

•

Always travel on uphill gradients with a fully charged battery pack.

•

You should exercise particular caution when travelling on downhill gradients of any kind.

•

If travelling down slopes with a fully charged battery pack at a high speed, this can lead to a reduction in speed or the e-fix being 
forced to shut down due to overvoltage. For this reason, travel down slopes at a slow speed in such cases. This is advisable in any case, 
so that you are able to stop the wheelchair or avoid any obstacles that may suddenly appear.

•

Never travel across steep slopes or similar conditions. Unintentionally shifting the centre of gravity could result in the wheelchair tip-
ping over on its side.

•

When navigating inclined kerbs or in similar circumstances, you may need to countersteer a little. Never travel over minor obstacles 
such as kerbs by moving parallel to them, move at a right angle to the respective obstacle. This means that both wheels travel over the 
obstacle at the same time rather than being offset. Use a low speed that is appropriate for the obstacle.

•

At regular intervals, check that the front wheels are aligned at right angles to the ground and that they have the correct air pressure. 
Both factors influence the travelling and braking performance and the range of the e-fix.

•

Never travel without anti-tippers, and only remove them in order to navigate major obstacles. It is left to the judgement of the user as 
to whether to call an attendant for help when there is an increased risk that the wheelchair may tip over.

•

When travelling on public roads you must observe the provisions of the road traffic regulations. Your wheelchair is equipped with the 
additional equipment specified in this manual.

Exercise caution when travelling downhill with a fully charged battery pack.

Travelling at high speeds with a fully charged battery pack may lead to a reduction in speed or the system auto-

matically switching off. Therefore, reduce your speed.
