Introduction

1.1 Important safety notes– please observe carefully at all times
The via mobile is a push and braking aid to be used exclusively by the person accompanying the wheelchair user. The via mobile must under no circumstances be used as an electric drive system by the wheelchair user alone. For safety reasons, the mobile must only be operated by persons who

1. have been instructed in its handling,
2. are physically and mentally in a position to operate the device properly and according to the given operating conditions and situations.

The mobile must not be operated by patients who are visually or acoustically impaired. Instruction in the handling and operation of the device is included in the scope of delivery. Please contact your specialist dealer or an Alber agent to arrange for a training session. The instruction is free of charge. If you feel a little unsure how to handle the via mobile, please contact your authorized dealer or Ulrich Alber GmbH agent for advice. While operating via mobile, observe the specifications of the wheelchair manufacturer (e.g. maximum slope, air pressure of tires, etc.), and strictly adhere to the operating instructions of the wheelchair. Never exceed any of the specified limit values. Before using a mobile phone or similar device, always secure the wheelchair on level ground and switch off the via mobile. Avoid strong electromagnetic fields (for example, near large electric motors), as they may interfere with them via mobile. In rare cases, the operation of the via mobile may interfere with other electrical devices such as anti-shoplifting barriers in department stores.

Therefore, do not start via mobile before you have been properly instructed in its operation by an authorized specialist dealer or an agent of Ulrich Alber GmbH!
1.2 Proper use of the via mobile
The via mobile is an add-on drive attached to a manually operated wheelchair to assist the attendant of a wheelchair user in pushing the wheelchair. It thus enables people to take long drives without tiring as the effort for pushing and braking is greatly reduced. The electric motor of the via mobile makes it easy to push the wheelchair up a slope. When traveling down a slope, the mobile reduces the speed to the set level, which makes the operation of the wheelchair safer even on steep slopes. It is forbidden to make any technical modifications to the device. Do not attach any parts other than accessories approved by Ulrich
Alber GmbH for operation with the device. The via mobile must only be operated under the following conditions:

• Full compliance with the information, instructions, and recommendations contained in this operating manual.
• The device is operated by a person who has been instructed in its use.
• No technical modifications have been made to the device by the user or by any third party.
• While the via mobile is in use, the arms of the person sitting in the wheelchair must not project over the armrests of the wheelchair.

A trained operator is a person who has been instructed in the operation of the via mobile and in related tasks and who has been made aware of the possible hazards associated with the improper use of the device. The instruction session is provided by the authorized dealer or by an agent of Ulrich Alber GmbH. The operation of the via mobile by non-instructed or unqualified persons is strictly prohibited. The mobile must not be used for transportation tasks that contravene the intended use of the device.
This applies in particular to any type of load transport such as the transport of household objects by means of a wheelchair plus via mobile. The use of the via mobile for any of the following purposes is deemed improper by Ulrich Alber GmbH:

• Use or operation of the device that contravenes the instructions and recommendations in this operating manual.
• Exceedance of the technical limits laid down in this operating manual.
• Technical modifications to the device.
• Attachment and/or use of parts and accessories that have not been supplied or approved by Ulrich Alber GmbH.

Damage resulting from

• using the device improperly or
• use by a person who has not been instructed in the handling of the device shall not be deemed by Ulrich Alber GmbH as part of the company’s liability.

While the via mobile is in use, the person sitting in the wheelchair must remain still. Please note that their specific condition may cause some patients to move in an uncoordinated manner. Stop using the device in these cases until the patient has settled down. The person operating the device should be capable at all times to react to such sudden movements of the person being conveyed. It is, therefore, up to the person operating via mobile to decide whether a person can be safely transported on the device.
Before using the device, carefully read all safety and hazard information contained in the individual chapters of this operating manual.
1.3 Permissible operating conditions/locations of operation
The via mobile must only be used at ambient temperatures between -25°C and +50°C.
Observe the permissible operating conditions of the wheelchair to which the mobile is attached (see wheelchair manual). Any limits regarding the operation of the wheelchair (e.g. maximum climbing capability, the maximum permissible height of obstacles, max. load, etc.)must also be observed during the use of the via mobile!
Avoid using the wheelchair on soft ground (e.g. loose chipping, sand, mud, snow, ice or deep puddles).
Observe the safety and hazard information provided in the individual chapters of the operating manual.
1.4 Standard scope of delivery

• Drive unit
• Control unit
• Automatic charger
• Battery pack
• Operating instructions

1.5 Optional accessories

Start-up and driving mode

The via mobile is supplied to you ready for operation. This means that

• special brackets ([31] and [32]) to which the via mobile is attached have been mounted on either side of the wheelchair,
• the via mobile has been fitted to the wheelchair,
• the via mobile control unit [13] has been mounted on the push handles of the wheelchair or the additional push handles of the via mobile, which is available as optional accessories,
• and, if necessary, anti-tippers have been attached to the wheelchair or the via mobile (see chapter 7 for more information).

Your via mobile is, thus, ready for operation and can be started and operated by following the instructions in the chapters contained in this operating manual and the instructions given in the free instruction session of your authorized dealer or an agent of Ulrich Alber GmbH.

|
---|---

The installation of the brackets ([31] and [32]) on the wheelchair and all necessary adjustments to the via mobile must be carried out by Ulrich Alber GmbH, its agents, or your authorized specialist dealer.
Regularly check the brackets ([31] and [32]) to ensure that they are firmly screwed to the wheelchair. If a screw connection has become loose, contact your specialist dealer or Alber agent to have it retightened. It may be necessary to readjust the device.
Alber provides brackets of various designs (single-part or multiple-part brackets). The bracket shown in the figures of this operating manual may, therefore, deviate from that attached to your bracket.
Follow the operating and safety instructions as well as the hazard information contained in this operating manual before putting your mobile into operation.
2.1 Attaching the via mobile to the wheelchair

• Make sure that both manual drive wheels have been properly attached to the wheelchair.
• Apply the parking brake of the wheelchair so that it cannot roll away.
• Remove the quick pins [34] if they are seated in both forks [33] (see chapter 2.3).
• Remove the battery pack [9] from the via mobile.
• Use the carrying handle [5] to slide the via mobile under the wheelchair as shown in the diagram.

|
---|---

With the battery pack inserted:
Do not grab the releasing device [12] of the battery pack to slide or lift the via mobile as this may cause the battery pack to come loose (see chapter 9.3).

• Slide the lower bolt [1] of the via mobile into the lower holder [31] on the wheelchair until it reaches the stop.
• Once the lower bolt [1] of the via mobile is fully seated in the lower holder [31], slightly lift up the via mobile. When doing so, make sure the upper bolt [3] on the via mobile is inserted in the fork [33] of the upper holder.
  • Close the forks [33] on both sides with the quick pin [34] as soon as the upper bolt [3] of the via mobile is seated in the fork [33] (see also chapter 2.2).

The drive wheel [7] of the via mobile is now approx. 15 mm above the ground to allow the wheelchair to be moved manually if necessary and without the need to make use of
the via mobile.

2.2 Inserting the quick pins

• Hold the quick pin [34] between your index and middle finger as shown in the diagram.
• Push in the releasing device [35] at the center of the quick pin, using your thumb.
• Insert the quick pin through the upper bracket fully into the fork [33] until it reaches the stop.
• Release the released device [35]. The quick pin now locks the fork so that the upper bolt of the via mobile cannot become dislodged.

2.3 Removing the quick pins

• Hold the quickpin [34] between your index and middle finger.
• Push in the releasing device [35] at the centre of the quickpin, using your thumb.
• Pull the quickpin from the fork [33] of the upper bracket.

Ensure that the quick pin cannot be inserted into or removed from the fork without pushing in the releasing device [35]. If it can be inserted or removed without pushing in the releasing device, the quick pin is defective and must be replaced without delay.
If one or both quick pins are defective or not properly locked in the forks, do not attempt to use the via mobile.

2.4 Inserting the battery pack
You can insert the battery pack when the mobile is safely connected to the wheelchair as described in the previous chapter.

• Make sure the electrical connections on the mobile and the battery pack are clean and do not contain any metal particles. If you detect such particles, use a dry and clean cloth to remove them.
• Hold the battery pack by its releasing device [12].
• Place the battery pack slightly slanted onto the holder of the via mobile as shown in the diagram.
• Release the battery pack. It will automatically slide forward and engage by magnetic force.

Protect the battery pack against humidity, moisture, heat, and extreme cold.

2.5 Attaching the control unit
Two holders [22] have been fitted to the push handles of your wheelchair which are used for the installation of the control unit [13] and one push handle.
If the control unit [13] and the push handle have not yet been attached, proceed as described below.

• Insert the control unit [13] into the holder [22] of the wheelchair.

• Fold down the locking wheel [20] by 90 degrees.
  

• Turn the locking wheel [20] clockwise until the control unit [13] is seated firmly in the holder [22].
  • Insert the plug of the control unit [21] into the socket [11] on the battery pack. The connection is secured automatically and conveniently by magnetic force.

Make sure the plug of the control unit [21] and the socket [11] are clean and do not contain any metal particles. If you detect such particles, use a dry and clean cloth to remove them. For details, see chapter 12.2.
2.6 Switching on the via mobile
To switch on the via mobile, press and hold the ON/OFF button [14] for approx. 1 second. The button lights up green, the drive wheel [7] is extended until it reaches the floor, and an arrow symbol [38] starts flashing on the display.
Once the wheel is fully extended, the display [16] indicates the selected direction of travel (see chapter 2.7) and the charge status of the battery pack (see chapter 5.2). In addition, the selected speed (see chapter 2.8) is indicated on the display for a few seconds.
When switching on the via mobile, make sure your leg is not underneath the extended wheel. Risk of crushing injuries!
The charge status of the battery pack is also constantly indicated on the display [16]. For an overview of all possible indications, see chapter 5.2.
2.7 Selecting the direction of travel
You can use the ergonomically shaped driving direction switch [18] to set the direction of travel.

• Slide the driving direction switch [18] forward (diagram A); the via mobile will move forward when you actuate the driving lever [19].

• Slide the driving direction switch [18] back (diagram B); the via mobile will move backward when you actuate the driving lever [19].

• If the driving direction switch [18] is adjusted when the device is standing still, the via mobile will immediately move in the set direction when the driving lever [19] is actuated.

• If the driving direction switch [18] is adjusted during travel, the via mobile will stop automatically and switch the direction of travel as soon as the device is standing still. You will then have to release the driving lever [19] before pressing it again.
  This is necessary for the device to move in the indicated direction.

• The set direction of travel is indicated on the display [16] by an arrow (see chapter 6.1).

2.8 Selecting the speed
You can use the adjustment wheel [17] to set the maximum speed you want to reach before and during travel. When starting the device, always turn the adjustment wheel [17] to the position with the lowest speed and then gradually increase the speed to the desired walking speed.

• Turn the adjustment wheel [17] in the direction of travel to increase the speed.
• Turn the adjustment wheel [17] against the direction of travel to decrease the speed.

The set maximum speed can be adjusted continuously from 1.1 km/h to 5.5 km/h and 0.5 km/h to 2.7 km/h for traveling forward and backward, respectively, while the device is standing still or in motion.
While being adjusted, the speed (set value in relation to the maximum speed; see also chapter 6.3) is shown on the display [16] for a few seconds.
We recommend that drivers who use the via mobile for the first time start at a low final speed in order to become adequately familiar with the mobile’s driving characteristics.
Refrain from making your first driving attempts in narrow areas such as hallways.

Driving mode

3.1 Starting to drive
When you have made all the settings described in the previous chapters, you can start using the device. The driving lever [19] acts like the accelerator pedal on your car.

• Pressing lightly on the driving lever [19] causes the mobile to slowly move in the set direction of travel.

• If you depress the driving lever [19] all the way until you feel noticeable resistance, the via mobile will move in the set direction of travel and at the maximum speed, you
  selected (see chapter 2.8).

• When you release the driving lever [19], the via mobile will come to a standstill.

When the driving lever [19] is released, the via mobile will not come to an immediate standstill, but keep moving in the direction of travel for a short distance.
Therefore, stop in time before you run into an obstacle.

3.2 Safety circuit
Avoiding sudden obstacles or dangerous situations requires an immediate stop of via mobile, which is triggered by a safety circuit.

• Press the driving lever [19] all the way and past its regular resistance.
• The via mobile will stop immediately.
• The display shows the code “02” and a flashing info symbol [40]. In addition, the device will sound an audible signal.
• Releasing the driving lever [19] will turn off all indications and the audible signal.
• The via mobile will then be standing still.
• To resume driving, press the driving lever [19] again.

The regular way to bring the via mobile to a standstill is by releasing the driving lever [19].
If the safety circuit is triggered by pressing the driving lever [19] in a dangerous situation, the via mobile will come to an immediate and abrupt standstill. This may cause the wheelchair user to fall out of the wheelchair, especially if the device is stopped at maximum speed during (possibly too rapid) downhill travel.
We, therefore, recommend that the user drive with care and wear a lap belt!
Also, follow the instructions given in chapter 3.5
3.3 Automatic brake engagement
If the via mobile is switched on and the driving lever [19] is not actuated within 30 seconds, the electromagnetic brake will engage automatically. This prevents the wheelchair
from rolling away, in particular, if it is stopped at an incline. The brake is disengaged automatically when the driving lever [19] is actuated.
The display will only show the direction of travel [37] and the charge status of the battery pack [36] instead of any particular indicators.
When stopped at an incline, the wheelchair must also always be secured with the brakes on the wheelchair.

3.4 Anti-theft protection
To prevent it from being misused, the via mobile is equipped with an anti- theft device. The device can only be activated/disabled when the via mobile is switched on.
Activating anti-theft protection

• Place the key [23] directly onto the sensor field of the control unit that is marked with a key symbol [15].
• All indications shown on the display [16] go out, while the key symbol [39] remains visible.
• The anti-theft device is now activated.
• Switching off the via mobile (see chapter 3.8) does not affect the activation of the anti-theft device, i. e. anti-theft protection will be enabled when the device is switched back on.

Disabling anti-theft protection

• Place the key [23] directly onto the sensor field of the control unit that is marked with a key symbol [15].
• The display [16] stops showing the key symbol and shows the set direction of travel ([37] or [38]) and the charge status of the battery pack [36] instead.

3.5 Downhill travel with the battery pack fully charged
As a result of various environmental conditions and, in particular, during downhill travel with the battery pack fully charged, the increased feedback of energy that is intended to protect the battery pack will reduce the speed automatically. This is indicated to the driver by a flashing battery symbol on the display.
In extreme cases, this may cause the system to shut down automatically, which, in turn, will bring the via mobile to an immediate standstill. This is indicated on the display [16] of the control unit by error code “81” [41] and the adjacent info symbol [40]. In addition, the device will sound a 3-second audible signal.
To resume driving, you should travel uphill in order to consume energy. If you are required to drive uphill immediately – for instance, because of the location of your home – you should not fully charge the battery pack of your via mobile. This process is completed automatically when you drive downhill due to energy feedback.

3.6 Traversing obstacles
Use special caution when negotiating obstacles such as curbs. You can traverse obstacles both when driving forward and backward. Higher obstacles make it necessary to lift up or push down the wheelchair by its push handles (instead of using the control unit or the additional handle on the via mobile). You do not have to switch off the via mobile for this purpose.
The height of some obstacles you need to traverse may no longer make it possible to push via mobile as the drive wheel may no longer be in contact with the ground depending on the wheelchair’s angle of inclination. In such cases, approach the obstacle at a 20-degree angle rather than at a right angle.

Approach every obstacle at a slow pace and break in good time before you reach it!
Make absolutely sure not to approach the obstacle at maximum speed, prevent the wheels to bump into the obstacle and never attempt to traverse the obstacle at maximum speed. Such driving maneuvers may especially damage the front wheels of the wheelchair or (in extreme cases) cause them to break off.
When traversing obstacles (see chapter 3.6), do not lift up or push down the wheelchair by means of the control unit or the additional handle.
Similarly, do not tilt the wheelchair by pressing down on the battery pack with your foot.

3.7 Manually engaging/disengaging the drive wheel (Emergency release)
If you’re via mobile can no longer be operated, for instance, due to a drained battery pack, the device will switch off automatically. In this case, the display will show code “41” next to the info symbol (see also chapter 6.5). The residual energy remaining in the battery pack is usually sufficient to switch the via mobile on and off again, which will automatically retract the drive wheel [7]. If this is not possible, you can manually disengage the drive wheel by following the instructions below.

• Pull the handle of the releasing device [6], which is located on the right side of the drive wheel, outward while turning it in any direction by approx. 90°.
• The coupling has now been released (see fig. A), the drive wheel can be moved manually and the wheelchair can be pushed.
• Recharge the battery pack (see chapter 5.1).

You must re-engage the wheel before putting the via mobile back into operation.

• Turn the handle of the releasing device [6] in any direction until it locks back into the drive wheel.
• Check if the drive wheel is properly locked in place – it must no longer be possible to turn it manually
• If the drive wheel has been locked correctly (see fig. B), the via mobile can be operated again as normal.

Before disengaging the drive wheel [7], you must tighten the manual brakes on the wheelchair (in particular, at an incline) in order to prevent the wheelchair from rolling away.
If the drive wheel [7] is still engaged when the via mobile is switched on, the display will show error code “72”. Engage the drive wheel.
If the error message ‘70’ appears on the display, then the drive wheel [7] is still disengaged. Engage the drive wheel.

---|---|---

3.8 Switching off the via mobile
When you are finished driving, you should switch off the via mobile – not least, in order to conserve the power stored in the battery pack.

• To switch off the via mobile, press and hold the ON/OFF switch [14] for approx. 1 second.
• The drive wheel [7] lifts off the ground, and the arrow symbol [37] shown in the adjacent diagram flashes on the display.

When the wheel is fully off the ground, all indications are shown on the display [16], the green light of the ON/OFF switch [14], and the capacity indication [42] on the battery pack will go out.
Never switch off the via mobile when parked at an incline! Switching off the via mobile will lift its drive wheel off the ground, robbing the device of its brake force.
If switching the device off at an incline cannot be avoided, you must engage the manual brakes on the wheelchair before switching it off via mobile.
When experiencing a technical fault, the via mobile will shut down automatically. In this case, too, the drive wheel remains on the ground at first before lifting off the ground when the system restarts. Consequently, the manual brakes on the wheelchair must be applied to prevent the wheelchair from rolling away.
Before switching off the via mobile, always apply the manual brakes on the wheelchair to prevent the wheelchair from rolling away.

Removing the mobile from the wheelchair

Normally, the via mobile is permanently attached to the wheelchair. Proceed as follows if detaching the via mobile becomes necessary, for example, to allow for the transport of
the device.
4.1 Disconnecting the control unit

• Apply the brakes on the wheelchair to prevent the wheelchair from moving inadvertently.
• Switch off the via mobile (see chapter 3.8).
• Pull the plug of the control unit [21] from the socket [11] on the battery pack as shown in the diagram.

If the plug of the control unit [21] is pulled from the battery pack while the via mobile is switched on, the drive wheel will lock up. Consequently, the mobile must always be switched off before the plug [21] can be pulled.
Do not disconnect the control unit via mobile by pulling on the cable of the control unit! This may cause the plug to snap back and hit you.
4.2 Removing the mobile from the wheelchair

• Turn the knob [20] counter-clockwise by approximately 3 rotations
  

• Fold up the knob [20] by 90 degrees
  

• Pull the control unit out of its holder [22] on the wheelchair.

Transport and storage

9.1 Using the mobile as a vehicle seat in combination with a wheelchair
Using a wheelchair as a vehicle seat with the via mobile attached is prohibited. If the vehicle is equipped with a lifting platform or similar equipment, exercise extreme caution when driving the wheelchair including the via mobile onto the platform. Drive slowly and carefully. Do not make any sudden, abrupt, or jerky movements. Look in the direction of travel and avoid any distractions.
When moved inside the vehicle, the wheelchair user must be switched to a regular seat in the vehicle where he is protected by the vehicle’s safety system, e.g. airbags and side impact protection.
While the via mobile can remain attached to the wheelchair during travel, its battery pack must be removed and stored in a safe place. Ulrich Alber GmbH shall not be liable for any accidents and their consequences or damage to the wheelchair, the via mobile or any other objects and installations that result from non-compliance with these requirements and instructions.
9.2 Safety note regarding the transport of via mobile
While the via mobile can remain attached to the wheelchair during transport, its battery pack must be removed. The Control unit and battery pack must not remain connected during transport.
When removing the via mobile from the wheelchair, make sure to secure the device and all of its components (battery pack, control unit, additional push handles, and anti-tippers) in such a way during transport inside a vehicle that they do not pose a risk to the driver or the passengers in the event of a sudden brake maneuver. To secure the via mobile in the car, we recommend tying the individual components with suitable straps to the vehicle. Please note that it is the responsibility of the owner to ensure that all components are properly secured and that Ulrich Alber GmbH shall not be held liable for any damage caused by unsecured parts. The individual components of the via mobile must never be stored unless they are properly secured! Please check whether there are specific regulations regarding the transport of the via mobile or its components in your jurisdiction and strictly adhere to these regulations.
Accidents of any kind and their resulting consequences as well as damage to the wheelchair or the mobile that

• resulted from non-compliance with these instructions
• occurred due to non-compliance with the laws and regulations in the country of use
• and can be attributed to the use of impermissible or unsuitable safety systems shall not be deemed as situations for which Ulrich Alber GmbH and their agents are liable.

9.3 Safety instruction on how to hold the via mobile
Moving the via mobile manually or holding it during transport requires that the battery pack is removed (see chapter 4.3).
Once this has been done, you can hold the via mobile by its carrying handle [5] as shown in the adjacent diagram.
Actuating the releasing device [12] disconnects the battery pack via mobile!
Therefore, never hold the via mobile by the releasing device [12] of the inserted battery pack regardless of whether you hold the via mobile during transport or move it manually.

---|---

9.5 Storage

• To store the via mobile, place it on a surface that is easy to clean. Experience shows that certain tires (e.g. bicycle tires) can leave behind residue on some plastic floors (for instance, PVC floors) that cannot be removed. The via mobile is also equipped with such commonly used tires. If you are unsure in this regard, we recommend that you use cardboard as padding. Ulrich Alber GmbH denies all liability for any damage caused to floors.
• If you wish to store the via mobile for a prolonged period of time, you must keep the device and, in particular, the battery pack in a dry environment, preferably at room temperature (+15 °C to +25 °C).
• If storing the via mobile for a prolonged period, do not rest the device on its drive wheel [7], as the device may otherwise start to wobble (over time).
• If stored exclusively, the battery pack should be connected to the supplied battery charger at a 3-month interval to be fully recharged. This ensures that your via mobile is working properly even after prolonged storage.
• After the battery pack has been charged, disconnect the charger from the power mains.
• The batteries consist of lithium-ion batteries. If stored and handled correctly, they are leak-proof and do not require any maintenance apart from regular recharging.
• If storing it for an extended period, switch on the via mobile once a month and move the wheelchair a few meters forward and back to prevent seizing of the brake and similar damage.

Safety and hazard information

To ensure safe operation and use of your via mobile, strictly adhere to the following instructions.
10.1 Safety instructions Before using the device:

• Before a user can take a seat in the wheelchair, the brakes on the wheelchair must be applied, and the via mobile must be switched off in order to prevent the wheelchair from rolling away.
• If you discover that a feature of the via mobile does not work as described in this operating manual, you must not continue to use the device. Contact your specialist dealer or an agent of Ulrich Alber GmbH to have the error corrected.
• Never use the via mobile as a footboard.
• Before using the via mobile to drive up or down a slope, practice the operation of the add-on drive on level ground.
• The via mobile must only be attached to wheelchairs that have been approved by Ulrich Alber GmbH for operation with the add-on drive.
• The bracket holding the via mobile in place may only be installed and modified by Ulrich Alber GmbH, an Alber agent or your authorized specialist dealer.
• When using the via mobile, always strictly adhere to the operating instructions of the wheelchair.
• The via mobile must only be operated by the attendant. As there is a risk that the wheelchair may topple over when driving on slopes, the device must not be used as a self-drive device. The attendant must at all times be in a position to prevent the wheelchair and its passenger from tipping over. Please note that the wheelchair may tip over forward or backward.
• We strongly recommend equipping the wheelchair with anti-tippers. When climbing slopes of more than 8 %, the use of anti-tippers (installed in pairs) is mandatory.
• The parking brakes of the wheelchair to which the via mobile is attached must be positioned in such a way that they can be easily operated by the attendant while pushing the wheelchair.
• The drive wheel of the via mobile is a tubeless full-rubber tire. Before setting the wheelchair in motion, check the condition of the wheel. The tire tread pattern must still be adequate. If the rubber tread pattern shows any cracks, the via mobile must no longer be used. A new wheel can only be purchased by your authorized dealer as a spare part from Ulrich Alber GmbH.
• Ensure that the air pressure in the wheelchair tires corresponds to that prescribed by the wheelchair manufacturer. Both parameters directly affect the performance of the parking brakes.
• The via mobile should be inspected and serviced every 2 years by Ulrich Alber GmbH, an Alber agent, or your authorized specialist dealer (see chapter 12.5).

When using the via mobile, observe the following:

• When starting the device, always turn the rotary switch [17] that is used for selecting the speed to the position with the lowest speed and then gradually increase the speed to the desired walking speed.
• The maximum permissible angle of inclination is 11.5 percent at a maximum payload of 160 kg. Greater slopes or inclines require that the operator be in a position to prevent the wheelchair from tipping over (in any direction) at all times.
• Under no circumstance must you exceed the maximum permissible slope specified by the wheelchair manufacturer while driving up and down slopes and inclines.
• Before driving down a slope, readjust the speed using the rotary switch [17] to ensure that it is not greater than the walking speed of the attendant.
• Never drive up and down slopes with the drive wheel [7] unhitched unless there is an emergency.
• Never approach stairs, precipices or steep slopes at maximum speed.
• While the via mobile is switched on, each actuation of the driving lever [19] is converted into a drive command. It is, therefore, imperative that inadvertent actuation is prevented. When stopping or waiting in potentially dangerous positions (e.g. while waiting at a traffic light, in front of slopes or ramps of any type), switch off the mobile and do not touch the driving lever [19].
• Ensure that children do not touch the driving lever [19] or set the via mobile in motion.
• Do not attach any objects (shopping bags, etc.) directly to or near the control unit! Such objects may actuate the driving lever [19], which could result in inadvertent drive pulses. • Do not attach any objects (shopping bags, etc.) to the additional push handles as they may actuate the driving lever [19], which could result in inadvertent drive pulses. • When driving on pavements, keep a safe distance (preferably the width of the wheelchair) from the curb.
• To drive over curbs, you can drive forward or backward without having to switch off the mobile. Lift the wheelchair by its handles (and not by the handle on the control unit or the additional handle). When driving over curbs, observe the maximum climbing height specified by the wheelchair manufacturer.
• Avoid using the wheelchair on soft ground (e.g. loose chipping, sand, mud, snow, ice, or deep puddles).
• Never leave the via mobile unattended, even if it is switched off. However, if this cannot be avoided, you can activate anti-theft protection (see chapter 3.4).
• During prolonged trips, the drive system of the mobile may become hot. Do not touch the drive system immediately after a long trip (e.g. to place the via mobile in the car, etc.). • Take care not to store the via mobile in places that are exposed to direct sunlight. The degree to which the components of the via mobile may heat up varies with the intensity of their exposure to the sun.
• The performance of the via mobile can be affected by electromagnetic fields that are produced, for example, by mobile phones. There- fore, switch off the add-on drive if a mobile phone is used in the vicinity of the wheelchair.
• Conversely, the via mobile may interfere with other electrical equipment such as anti-shoplifting barriers in department stores.

Observe the following when finished using the via mobile:

• Before a user can leave the wheelchair, the brakes on the wheelchair must be applied, and the via mobile must be switched off in order to prevent the wheelchair from rolling away.
• When not in use, the via mobile must be switched off to prevent inadvertent triggering of drive pulses when the driving lever [19] is touched and prevent the battery from discharging completely. Apply the manual brakes on the wheelchair.
• Park the wheelchair and the via mobile only in dry and safe places. Never allow moisture to enter via mobile or the battery pack and the control unit.
• Recharge your battery pack of your via mobile as soon as possible after each trip.

10.2 Obstacles
You can traverse obstacles such as curbs both when driving forward and backward. You do not have to switch off the via mobile for this purpose. Lift the wheelchair by its handles (and not by the handle on the control unit or the additional handle). When driving over curbs, observe the maximum climbing height specified by the wheelchair manufacturer.
10.3 Danger areas and hazardous situations
The attendant operating via mobile must decide in each case whether it is safe to use the add-on drive for the intended trip based on issues such as driving experience and physical strength. Before undertaking a trip, check the via mobile wheels for damage and proper inflation. Also, check the battery charge level, the proper operation of the control elements, and the manual brakes on the wheelchair. These safety checks and the experience of the attendant operating the via mobile are of particular importance in connection with the operation of the add-on drive in or near the following danger areas:

• narrow footpaths, steep slopes (e.g. ramps), narrow paths along slopes, and mountain paths.
• narrow and/or steep/inclined paths along main roads or near precipices.
• paths covered with leaves, snow or ice.
• ramps and lifting platforms of vehicles.

Use extreme caution when driving along quay walls, berths, and marinas, paths and areas near water, bridges and dykes without railings. Never drive too closely to bodies of water.
The via mobile supports slopes and inclines of up to 18 %. The maximum permissible angle of inclination is 11.5 per cent at a maximum payload of 160 kg. Greater slopes or inclines require that the operator be in a position to prevent the wheelchair from tipping over (in any direction) at all times.
The basic safety requirements include proper tyre profiles, correct wheelchair tyre pressure, firm ground and a maximum load of 160 kg on the wheelchair. When driving along bends, turning the wheelchair or driving uphill or downhill, the center of gravity of the wheelchair may be shifted so that there is a risk that the wheelchair may tip over to the side. Therefore, proceed with extreme caution and reduce the speed of the add-on drive! Special caution is required when crossing main roads, crossroads and level railway crossings! Never push the wheelchair at a small angle over rails, as the wheels could be jammed in the rails! Proceed with special caution when driving over ramps or lifting platforms of vehicles. Before lifting or lowering the wheelchair on the ramp or lifting platform, switch off the viamobil. Do not actuate the driving lever [19]. Apply the hand brakes of the wheelchair. This prevents the wheelchair from rolling away, for example by inadvertent drive commands.
If the ground is wet, the tyres adhesion may be poor so that there is a risk of slipping. Adjust your driving behaviour accordingly.

Maintenance, care, and disposal

11.1 Charging the battery pack
You’re via mobile uses power in all operating modes. Avoid fully discharging the battery pack, as this could cause damage to the batteries. We recommend recharging the battery pack immediately after every use.
To charge the battery pack, use only the mains charger supplied with your via mobile. The charging process ends automatically when the battery pack is fully charged. This avoids overcharging.
For detailed instructions regarding the battery pack, see also chapter 5.
11.2 Cleaning and disinfection instructions
When cleaning the device, never use cleaning benzine, thinner, acetone, or similar agents. Instead, use only conventional household cleaning agents and disinfectants (isopropyl alcohol).

• Clean the control unit, the push handle, and the battery pack only with a moist (not wet) cloth.
• Clean the bracket attached to the wheelchair with a moist (not wet) cloth.
• Regularly clean the drive wheel using a dry brush or compressed air cleaner.

Check all electrical connections (charger socket/control unit connection [11], a plug of the control unit [21], and charging plug [26]) for possible contamination before assembling them.
The magnetic force generated by the components may cause metal particles such as chips or similar objects to settle on the surfaces of the components, which may result in a short circuit.
Clean the components using a clean and dry, but never wet or moist cloth.
Your mobile is a low-maintenance device. With the exception of the tires, the add-on drive does not contain worn parts. To ensure that the driving force and the braking force of your via mobile are transferred properly, the tires must have an adequate tread pattern.

Disinfection instructions

• Rub off all surfaces via mobile and its components using a moist (not wet) cloth.
• Please note that neither the via mobile nor its components may be blasted off with a steam blaster or similar equipment.
• Apply the disinfectant to all surfaces of the via mobile and its components.
• Let the disinfectant soak following the instructions provided by the manufacturer.
• Remove the disinfectant by wiping it off or as prescribed by the manufacturer.

When storing the via mobile for an extended period, you may, in rare cases, an experience that visible residue remains and sometimes pressure marks are left behind on carpets or floors (if they are in contact with the tire), which vary with the respective use of floor detergents or impregnating agents. We do not assume any liability in such cases. We generally recommend that you store the device on hard-wearing floors and, for prolonged storage, on a protective mat or cardboard pad
Should you observe a deterioration of the driving behavior of your via mobile (e.g. irregular rolling, slipping wheels), contact your authorized specialist dealer or Alber agent to check the tires.
All service and repair work via mobile must be carried out by the manufacturer, an Alber agent, or an authorized specialist dealer. If you encounter any problems with your via mobile, contact your authorized specialist dealer or Alber agent.

The product is labeled in accordance with European Directive 2002/96/EC (WEEE Directive) with a “crossed-out rubbish bin” symbol, reminding you that it must be recycled. Please take care of the environment and return the product at the end of its service life to your local recycling center. As this product is not covered by the regulations of the WEEE Directive in all European countries, please inform yourself of the applicable waste disposal regulations in your country. In Germany, the product is, for instance, classified as a transport vehicle and, thus, not covered by the Electrical and Electronic Equipment Act implementing the WEEE Directive.
Alternatively, return the product to your authorized specialist dealer or Alber agent for proper and safe disposal.
11.4 Re-use
If you via mobile has been provided to you by your health insurance company and you do not need it any longer, please contact your health insurer, Alber agent, or authorized specialist dealer. You’re via mobile can then be given to somebody else. Before the via mobile is re-used, its safety must be checked. The brackets with which the via mobile is attached to the wheelchair can be easily and quickly removed by the authorized dealer or Alber agent and mounted on another. Before re-using the via mobile, clean it as described in chapter 12.2 and disinfect the control unit and the housing of the battery pack. To do this, use a product based on isopropyl alcohol that is suitable for wiping disinfection. The product must have an alcohol concentration of 70 %. Observe the use instructions of the product.
11.5 Maintenance
Lawmakers have laid out the execution of safety inspections in the Medical Devices Operator Ordinance (MPBetreibV). Safety inspections (hereinafter referred to as STK) are intended to verify the operation and safety of the product, uncover any defects and, if necessary, initiate steps/repairs that will restore the product to proper working order. Section 6 of the MPBetreibV stipulates that the manufacturer has to specify an interval at which this STK is to be performed and which must not exceed 2 years with regard to the products listed in appendix 1. Based on our market observations, an interval of 2 years has proven reasonable for products used as mobility aids that are used under normal operating conditions. This guideline value of 2 years may vary with the product’s respective degree of utilization and the behavior of the user. Checking the degree of utilization and user behavior is the responsibility of the operator. In any case, we strongly recommend that you clarify beforehand to what extent the cost of the STK is covered by your health insurance provider, especially with regard to any existing contracts.
