In the event of a problem or error message, immediately contact your specialist dealer.
Observe the following safety instructions and hazard information.
3.3 Safety instructions
• The system must be switched off at the control unit before the Esprit wheels are fitted to the wheelchair or removed from it. Similarly,
the system must be switched off before starting work on the wheelchair.
• In the (unlikely) event of the battery pack overheating or catching on fire, you must ensure that the battery pack does not come into
contact with water or other liquids. The only suitable extinguishing agent recommended by the battery manufacturers is sand.
Before beginning your trip:
• The Esprit may only be attached to push rim wheelchairs that have been approved by Alber GmbH for this device.
• The bracket holding the Esprit in place may only be installed and modified by Alber GmbH or an Alber authorised specialist dealer.
• When using the Esprit, always strictly adhere to the operating manual for the wheelchair.
• Using the wheelchair without a pair of anti-tippers attached is not permitted.
• Attach the original anti-tippers of the wheelchair manufacturer or the optional Alber anti-tippers to your wheelchair.
• Before each trip, check the condition of the Esprit wheels. If the tyres have reached their wear limit (if you can no longer see the
tread), the Esprit must no longer be used.
• Check the air pressure of the Esprit wheels at regular intervals. The table in chapter 12 contains information about the correct air pres-
sure. This information can also be found on the outside of the tyres. Please check the air pressure of the front wheels in accordance
with the instructions and specifications of the wheelchair manufacturer. Insufficient air pressure can severely affect the handling and
range of the wheelchair.
• Both Esprit wheels should always have the same air pressure.
• Both front wheels of the wheelchair should always have the same air pressure.
• Before every trip, check that the Esprit wheels are seated correctly in the wheel retainer [2] of the two brackets [1].
• The Esprit must not be used in combination with a wheelchair towing device or hand bike, or other pulling devices. In such cases, use
your manual wheelchair wheels instead of the Esprit wheels.
Always observe the following rules when travelling using the Esprit:
• Before using the Esprit to navigate uphill or downhill gradients, you should be able to operate the device safely on level ground.
• The maximum permissible slope specified by the wheelchair manufacturer must not be exceeded.
• Be very careful when approaching steps and drops.
• If the Esprit is switched on, each touch of the joystick is converted into a travel command. When stopping or waiting in potentially
hazardous areas (e.g. while waiting at a traffic light, on uphill and downhill slopes or ramps of any type), do not touch the control unit.
• Never reach into the wheel when the Esprit is switched on.
• Do not insert or throw objects of any kind into an Esprit wheel, regardless of whether or not it is switched on.
• Never attach objects of any kind to the Esprit wheels. This could cause damage.
• When travelling on pavements, keep a safe distance (preferably the width of a wheelchair) from the kerb.
• Avoid using the wheelchair on soft ground (e.g. loose chipping, sand, mud, snow, ice or deep puddles).
• Never leave the Esprit unattended, even if it is switched off.
• The Esprit may be adversely affected by strong electromagnetic fields.
• Under certain circumstances, the Esprit may interfere with other electrical equipment such as anti-shoplifting barriers in department
stores.
• You must not use the Esprit on escalators or moving walkways.
• When moving at maximum speed, do not suddenly change your direction of travel to the left or right, as this could cause the wheelchair
to tip sideways.
• Reduce your speed when turning a corner.
• If you intend to stop in your wheelchair on an uphill or downhill gradient, your wheelchair must be parked across this slope.
• Never navigate across downhill slopes.
• Never reach into the front wheels of your wheelchair or the spokes of the Esprit wheels when travelling.
• Apply the Esprit brake carefully and adjust your speed accordingly (i.e. not suddenly).
• When travelling in a vehicle, always sit in the vehicle’s installed seats with the appropriate restraint systems. Failure to comply with
this guideline may result in injury to you and your co-passengers in case of an accident.
