Please observe the following if the power wheelchair is not used for more than 3days:
11490E163=*
Delivery

Storage conditions
• Store the power wheelchair in a dry, enclosed room with sufficient air circulation and protection from external
influences. Specific information about storage conditions: see page45.
• Protect the wheels against ground frost, forexample by taking all weight off them using an assembly stand or
by setting them onto wooden blocks.
• Maintain sufficient clearance from sources of heat. If the product is parked for an extended period of time or
the tyres overheat (e.g.in the vicinity of radiators or in case of exposure to strong sunlight behind glass), the
tyres may become permanently deformed.
• Rotate the wheels weekly to prevent flat spots from extended standing.
• For extended storage, store the power wheelchair so the wheels are not in contact with the ground.
Note regarding the tyres
• If the power wheelchair is not moved for several days, permanent colour changes may develop where it comes
into contact with the ground. A suitable base should therefore be used when parking it for extended periods of
time.
• Avoid unnecessary parking outdoors. Direct exposure to sunlight/UV radiation causes the tyres to age more
quickly. As a result, the tread surface hardens and corner pieces break out of the tread.
• The tyres must be changed when the tread is less than 1mm (0.04") to ensure safe driving behaviour.
• The tyres should be replaced every 2years regardless of wear and tear.
• When power wheelchairs with PU tyres are parked for longer periods, the tyres may become deformed (flat
spots). This deformation will go away on its own over time while driving.

[Selected speed level] LED display
The LED display shows the currently selected speed level (1–5).
[Charge level] LED display
The [Charge level] LED display is divided into five segments and serves as a proportional indicator for the current
charge level:
• The accuracy of the indicator increases after driving for a short time.
• A charge of 100percent corresponds to five segments on the battery symbol.
• As the remaining battery charge decreases, the LED segments turn off one by one.
• When the last single LED segment flashes, the battery has to be charged immediately.
• When all five LED segments repeatedly flash once with pauses, the battery is in an undervoltage state. The bat
tery must be charged immediately.
• When all five LED segments repeatedly flash ten times with pauses, the battery is in an overvoltage state.
Please continue to drive at low speed only.
• The charging process is indicated by sequential flashing of the LEDs. The driving function is blocked when the
battery is charging.

CAUTION
Use of elevators, lifting platforms
Risk of tipping, collision with persons or nearby objects due to incorrect parking
►Always turn the power wheelchair control unit off when using elevators or lifting platforms.
►Make sure that the brake is engaged.
CAUTION
Safe positioning when using public transit
Crushing, pinching, impacts, collision with persons or objects, damage to the product due to human error
►Only use public transit approved for the transportation of power wheelchairs.
►Always observe the current applicable transportation guidelines of the transit company and/or the legal
requirements in your country when using public transit.
►Always ensure that you are held in place securely when travelling on public transit. To do so, use the wheel
chair areas, wheelchair bays and restraint systems provided. Turn the power wheelchair off before the vehicle
starts to move.
►The transportation of a person sitting in a wheelchair in public transit constitutes a significant safety risk for all
participants. We therefore recommend using the seats provided during transportation.
►While using public transit, you are not permitted to sit in the wheelchair without an approved personal
restraint system.
Danger when carrying across obstacles
WARNING
Improper lifting by attendants
Tipping over, falling of the user due to lifting on components that come loose or are not intended for lifting
►Only ever lift the product with the assistance of a helper. In this case, you and the helper grasp the frame
tubes underneath the seat with both hands on either side of the product.
►Do not lift the product on components installed with screw connections, or on add-on or plug-on components
(e.g.on the back support, leg supports or forearm supports).
Hazards due to defective tyres
CAUTION
Defective tyres
Accidents/falls due to poor traction, reduced braking force or lack of manoeuvrability
►Ensure that the tyres have sufficient tread depth. The tyres must be changed when the tread is less than
1mm.
Additional information
INFORMATION
►During use of the power wheelchair, electrical discharges (high voltage with low current; discharge via the
user) may occur which are caused by factors suchas friction. However, these do not represent a health haz
ard.
►Electrostatic discharge may also occur if the power wheelchair is equipped with puncture-proof tires.

7.7.2 Driving notes
General information:
• Prior to each use, the charge level of the batteries must be checked to avoid stalling due to drained batteries.
• Beginners should always drive at a low speed level.
• Always take curves slowly.
• On uneven ground, the driving behaviour of the wheelchair may get out of control. Therefore the speed must
always be adjusted to the ground conditions.
• Driving backwards should be limited to manoeuvring and short distances on level ground.
Obstacles (steps, curbs, tracks):
• Always approach obstacles directly from the front (never at an angle with only one front wheel).
• Starting at a maximum distance of 10cm from the obstacle is permissible.
• Always reduce speed to cross over obstacles (e.g.select speed level 1 or 2).
• Note the information on the critical obstacle height (see the section "Technical data"). Crossing over obstacles
greater than the height difference specified there is not permitted.
• Avoid "jumping" down from higher surfaces.
• Do not lean out of the wheelchair while crossing obstacles.
• Only cross railway systems and railway tracks in the designated areas.
• Do not negotiate railroad crossings too close to the edge. Otherwise, the wheels could accidentally move off
the railroad crossing.
Terrain:
• The speed must be reduced in dangerous areas (e.g.select speed level 1).
• Typical dangerous areas include:
– Narrow paths along waterways/slopes/cliffs (e.g., quay walls, dikes, etc.)
– Cramped rooms or areas
– Steep downgrades (e.g., in the mountains, facing streets)
– Unsurfaced areas (e.g., on construction sites, intersections, train crossings)
– Snow-covered or icy areas
Inclines and gradients:
• Note the information on permitted inclines and downgrades (see the section "Technical data"). Driving on
inclines or downgrades exceeding the specified values is not permitted. The wheelchair may otherwise tilt and
not brake safely. The traction of the drive wheels is also reduced.
• The control device and the motors must be protected against overloading. Therefore, the continuous climbing
ability depends on the overall weight (wheelchair weight + user weight + load), as well as the ground condi
tions, exterior temperature, battery voltage and driving style of the user. In individual cases, the continuous
climbing ability may be significantly lower than the value specified.
• In order to navigate downhill gradients safely, the speed must be reduced according to the slope (e.g.select
speed level 1).
• Never drive downhill backwards. Only briefly manoeuvring on ramps is permitted (for example, when exiting a
vehicle for transporting persons with reduced mobility).
• The product may not be used in salt water.
Using the control device:
• The control system always has to be mounted securely and the joystick position must be correct.
• If the power wheelchair does not drive at full speed even when the battery is fully charged, the selected speed
level should be checked. Contact the qualified personnel if increasing the speed level does not solve the prob
lem.
