6.2 Warning for uphill and downhill gradients
6.2.1 Uphill gradient
The nominal uphill gradient of the Esprit E34z is 6° (10.5%). If you navigate an uphill gradient that
exceeds this value, the adjacent warning symbol is displayed on the control unit. Reduce your speed
and navigate your way slowly and carefully out of the uphill gradient.
6.2.2 Downhill gradient
The nominal uphill gradient of the Esprit E34z is 6° (10.5%). If you navigate a downhill gradient that
exceeds this value, the adjacent warning symbol is displayed on the control unit. Reduce your speed
and navigate your way slowly and carefully out of the downhill gradient.
If an uphill or downhill gradient of 30 degrees is exceeded, warning message C30
is displayed (see chapter 6.1). If this error message is displayed, the installation
position of the control unit is outside the permissible angle in most cases.
When navigating uphill gradients, downhill gradients or steep ramps, the back-
rest of the wheelchair (if it is adjustable/foldable backwards) must always
be in the most upright position to prevent the system from tipping onto the
anti-tippers.
7. Storage, care, maintenance and disposal
7.1 Storage
If your wheelchair and the Esprit are going to be stored for an extended period of time (e.g. several months), please observe the following
points:
•
Store the wheelchair according to the wheelchair manufacturer's specifications.
•
Protect the components of the Esprit with film in order to keep moisture out.
•
Store the wheelchair and all Esprit components in a dry room.
•
Ensure that no moisture penetrates into or drips onto the wheelchair or Esprit components.
•
Ensure that the wheelchair and Esprit are not continuously exposed to solar radiation (e.g. through windows).
•
Ensure that unauthorised persons (especially children) do not have unsupervised access to this room.
•
Follow the instructions for storing the battery pack in chapter 4.10
•
The wheelchair and the Esprit components must be cleaned prior to recommissioning. In particular, it must be ensured that there are no
metallic particles on the plug [30] of the control unit or in the socket [16] of the interface.
•
Check whether maintenance is required before recommissioning (see chapter 7.4) and arrange this if necessary.
7.2 Care
Water ingress can permanently damage the drive.
For this reason, do not clean the individual components of the Esprit under running water or with a high-pressure
cleaner.
Always ensure that no liquid or moisture gets into the wheel hub. Due to this requirement, the utmost caution must be exercised when
cleaning the Esprit. In particular, please observe the following instructions:
•
Clean the surface of the wheels with a dry or slightly damp cloth.
•
Never use scouring pads, abrasive detergents or aggressive chemicals to clean the components.
•
Never clean the components under running water, for example, using a hose or a high-pressure cleaner. This can cause water ingress,
causing irreparable damage to the electronics.
Alber GmbH accepts no liability for any damage caused by water inside the device.
