Introduction

1.1 Intended purpose
The smoov is designed to provide support to a manual, active wheelchair user.
The smoov is intended for wheelchair users who are physically and mentally able to safely control a manual wheelchair in typical situations, including inclines, even manually.
1.2 Important safety notes – please observe at all times
The smoov is an add-on drive for wheelchairs, comprised of a drive unit and a control unit. It must only be attached to and operated with wheelchairs that are listed in Alber’s mounting database. For safety reasons, it must only be operated by persons who

• have been instructed in its handling,
• can move and coordinate both hands or arms without major restrictions
• have the physical and mental ability to safely operate the wheelchair with the smoov attached to it in all possible situations (e.g. road traffic) and, in the event of the smoov failing to work or shutting down, are able to brake the wheelchair and stop safely.

A one-to-one instruction session on handling and operating the device is included in the scope of delivery. Please contact your specialist dealer or Alber GmbH representative to arrange for a training session. The instruction is free of charge.
If you feel a little unsure about how to handle your smoov, please contact your specialist dealer for advice.
In the event of technical faults, please contact your specialist dealer or the Alber Service Centre (Tel: 0800 9096 250).
When operating the smoov, observe the specifications of the wheelchair manufacturer (e.g. maximum slope, air pressure of tyres, the maximum speed etc.), and strictly adhere to the operating instructions of the wheelchair. Never exceed any of the specified limit values.
We recommend refraining from using the smoov in locations that are exposed to strong electric fields.
In rare cases, the operation of the smoov may interfere with other electrical devices such as anti-shoplifting barriers in department stores.
You must not use the smoov on escalators or moving walkways.
If carrying out sporting activities in the wheelchair, such as lifting weights or similar tasks, the smoov is to be switched off and the wheelchair’s parking brakes are to be applied before the activity begins.
Combining the smoov with accessories that have not been approved by Alber is also prohibited.
It is prohibited to start up the smoov before being instructed in how to use it.
Contact your authorised specialist dealer or Alber agent for this instruction.
Starting up the smoov before receiving instruction is contrary to the intended use and will, among other things, invalidate the warranty. Any use contrary to the intended use involves a risk of injury.
1.3 Proper use of the smoov
The smoov is a medical device for active wheelchair users who are reliant on a wheelchair as a result of their disability. The smoov is an add-on drive for wheelchairs that is attached to a manual wheelchair, converting it into an electrically driven wheelchair and  hus significantly increasingthe wheelchair user’s mobility and flexibility.
The smoov must always be used, transported, maintained and serviced as described in this operating manual. The smoov must only be attached to and operated with wheelchairs that are listed in Alber’s mounting database.
The selection is made by the specialist dealer or by Alber itself.

1.6 Permissible conditions of use/locations of operation

• Observe the permissible conditions of use of the wheelchair to which the smoov is attached (see wheelchair operating manual).
• In addition to observing the information provided about the smoov, it is also imperative to observe the information provided by the wheelchair manufacturer (e.g. maximum gradeability, maximum permissible height of obstacles, maximum user weight, maximum speed, etc.). The lowest values always apply.
• Any limits regarding the operation of your wheelchair (e.g. maximum gradeability, maximum permissible height of obstacles, maximum user weight etc.) must also be observed when using the smoov.
• The smoov must only be operated at temperatures between -25 °C and +50 °C. Therefore, do not expose the smoov to any heat sources (such as intense sunlight) as this may cause surfaces to reach high temperatures.
• Avoid using the wheelchair on soft ground (e.g. loose chipping, sand, mud, snow, ice or deep puddles).
• Take particular care to observe the safety instructions and hazard information provided in chapter 3.

Pairs of anti-tippers need to be fitted to the wheelchair in order to use the smoov.
Use of the smoov without anti-tippers is not permitted.
Especially when it is not in use, do not expose the smoov to strong sunlight for long periods of time, if possible.
This could cause the motor to heat up and in an extreme case, not be able to operate at full power. Plastic parts also age quicker under intense sunlight.
In case of overheating: Allow the smoov to cool down for at least 60 minutes.

Commissioning

The smoov and any accessories you ordered will be fitted to your wheelchair by Alber or your specialist dealer and delivered so that they are ready for operation. For this reason, there is a bracket or adapter axle on the underside of your wheelchair [22], in which the drive unit is inserted (see chapter 8.2 and 8.3), and there is a mount on the frame of the wheelchair for attaching the control unit (see chapter 2.3).
On delivery of your smoov, your specialist dealer or an Alber agent will show you how to operate the device and how to use any accessories you ordered. You will also be given this operating manual which, in addition to the technical information, also contains important information about operating the smoov. This information must be noted.
Due to the applicable transport regulations, the batteries of the drive and control unit are only charged to a maximum of 30 percent on delivery. You should therefore charge both batteries fully before your first drive with the smoov (see chapter 4).

Alber produces adapter axles and attachments in various designs. This explains why diagrams in this operating manual may differ from the parts mounted on your wheelchair. However, this does not have any effect on the functions of the smoov.
The parameter specifications contained in the following chapters are factory settings.
They can be changed via the optionally available Mobility app according to the wishes of the wheelchair user.
The wheelchair is steered and braked by its push rims. Particularly when braking, heat is generated due to friction
between the hand and the push rims (especially those made of plastic). We therefore recommend that you wear suitable gloves when operating the smoov to prevent blisters from forming on your hands.
It is strictly prohibited for any uninstructed or unqualified persons to use the smoov.
Speed limitation
For your own safety, we recommend that you do not exceed the specified maximum speed of the smoov or wheelchair (whichever is the lowest value) during daily use. We assume no liability for any damage which results from operation at speeds higher than the stipulated maximum speed.
Operating the smoov without two parking brakes attached to the wheelchair is not permitted.
Pairs of anti-tippers need to be fitted to the wheelchair in order to use the smoov.
Use of the smoov without anti-tippers is not permitted.
The highest achievable speed with the smoov drive unit is 6 or 10 km/h respectively. If this value is exceeded (e.g. when navigating slopes), the drive unit switches to idling. In such cases, you need to reduce the speed with the push rims. The drive unit switches on again automatically as soon as the wheelchair drops to a speed below the previously driven/set speed.
2.1 Attaching the drive unit to the wheelchair
With a little practice, active wheelchair users can attach the drive unit of the smoov themselves while sitting in the wheelchair. Alternatively, the drive unit can be attached to the wheelchair before the wheelchair user takes their seat. A helper may also attach the drive unit.
When attaching the unit, proceed (or have a helper) proceed as follows:

• Apply the parking brakes to prevent your wheelchair from rolling away inadvertently.
• Ensure that both the drive unit and the control unit are switched off. Both components may only be attached to the wheelchair if they are switched off.
• Hold the drive unit by its handle [4] and slide it under the wheelchair, as lifting the drive unit could cause the wheelchair to tip backwards!
• Lift the drive unit by its handle [4]. This causes the locking claw [9] to open automatically.
• Insert the locking claw [9] into the bracket or adapter axle [22] on the wheelchair and let go of the handle [4].
• If the locking claw [9] and the bracket or adapter axle [22] are connected to each other correctly, the handle [4] lowers to its resting position automatically.
• In addition, check that the drive unit is correctly connected to the wheelchair by gently moving the housing. In this regard, the drive unit must never be held or lifted by the handle [4], as this will undo the connection. The drive unit must also not be held in areas close to the drive wheel [8]. This is to prevent fingers being trapped by the horizontally rotating drive wheel, for example.

|
---|---

In these few steps, you have attached the drive unit to your wheelchair. Now it is time to install the control unit.
Please be aware that lifting the drive unit by the handle [4] opens the locking claw [9] and the connection with the bracket or adapter axle [22] is undone as a result!
Apply the parking brakes to prevent your wheelchair from rolling away inadvertently.
Make sure that the drive unit is switched off. The device may only be attached to the wheelchair if it is switched off.
2.2 Removing the drive unit from the wheelchair
Active wheelchair users (or a helper) may also remove the smoov themselves.

• Apply the parking brakes to prevent your wheelchair from rolling away inadvertently.
• Ensure that both the drive unit and the control unit are switched off. Both components may only be removed from the wheelchair if they are switched off.
• Lift the drive unit by its handle [4]. This causes the locking claw [9] to open automatically.
• Remove the drive unit from the bracket or adapter axle [22]. Slide the drive unit under the wheelchair, as lifting the drive unit could cause the wheelchair to tip backwards!
• Put the drive unit down in a safe place where misuse of the device (e.g. due to children playing) is ruled out.

Apply the parking brakes to prevent your wheelchair from rolling away inadvertently.
Make sure that the drive unit is switched off. The device may only be removed from the wheelchair if it is switched off.
2.3 Attaching and removing the control unit
A retaining plate [16] for mounting the control unit to your wheelchair was attached by your specialist dealer. You can insert the control unit in the retaining plate and remove it at any time.
Attaching the control unit

• Apply the parking brakes of your wheelchair.
• First switch off the drive unit completely (see chapter 3.6.2).
• If the control unit is switched on, switch it off as well (see chapter 3.6.1).
• Then insert the control unit into the mount [16a] on the retaining plate [16] at a slight angle. In doing so, hold the control unit by the handle at the bottom. Do not ever hold it by the speed dial [11] (see diagram).
• Tilt the control unit towards the retaining plate [16] until it audibly locks into place in the mount [16b].
• Check that the control unit is seated securely in the retaining plate [16].

|
---|---

When inserting the control unit into the retaining plate [16], do not ever hold it by the speed dial [11]. Hold it only by the handle (see diagram opposite).
This prevents you from switching on the control unit unintentionally.
Removing the control unit

• Apply the parking brakes of your wheelchair.
• If you have not already done so, switch off the drive unit completely (see chapter 3.6.2).
• Switch off the control unit (see chapter 3.6.1)
• Press the locking mechanism [17] on the lower end of the retaining plate [16].
• Remove the control unit from the retaining plate [16]. In doing so, hold the control unit by the handle. Do not ever hold it by the speed dial [11].
• Put the control unit down in a safe place.

When removing the control unit from the retaining plate [16], do not ever hold it by the speed dial [11]. Hold it only by the handle (see diagram opposite).
This prevents you from switching on the control unit unintentionally.
Information for left-handed persons

• Unless you specify otherwise when ordering the smoov, the retaining plate [16] is mounted on the right-hand side of the wheelchair as standard.
• The Mobility app allows the control unit to be switched to left-handed use at any time. Please consult the operating manual for the Mobility app for further information in this regard.

2.4 Setting the control unit
If desired or necessary, the position of the display [12] can be adjusted.

• Switch off the drive unit completely (see chapter 3.6.2).
• Open the cover [13] of the control unit.
• Loosen the three screws [26] on the back of the control unit by not more than half a turn. To this end, use an Allen key, size 2.5.
• Turn the ring [25] until the display [12] is in the desired position. Then carefully tighten the three screws [26] until the ring [25] can no longer be turned.
• Close the cover [13] of the control unit.

Drive mode

3.1 Switching on the system
The drive and control unit need to be switched on for use be possible. Carry out the following steps to this end:

• Switch off all Bluetooth devices in your immediate vicinity to prevent any interference with the connection between the drive unit and control unit.
• Ensure that the drive wheel [8] is correctly aligned with the drive unit (see chapter 3.4).
• Briefly press the button [3] on the drive unit. This switches on the drive unit. A brief acoustic signal sounds, the button [3] lights up green, and the display [2] indicates the capacity of the battery. (see chapter 5.1). The position light [7] now lights up as well.
• Switch on the control unit (this needs to be in the mount [16]) by pressing the button [10] on it for approx. 2 seconds.
• The LED [f] now indicates the capacity of the control unit battery in different colours (see chapter 5.2). If the LED [f] is flashing blue, this indicates an attempt to establish a connection to the drive unit via Bluetooth.
• If no Bluetooth connection is established within 10 seconds, the LED [f] flashes redfor 20 seconds. The control unit then switches off.
• If the Bluetooth connection is established between the drive unit and the control unit, the LED [f] on the control unit lights up continuously. See chapter 5.2. for the meaning of colour. The capacity of the drive unit battery is also displayed.

If no Bluetooth connection is established after you have performed the steps listed above, this may be due to the following reasons:
Incorrect alignment of the drive wheel
If the drive wheel [8] is in an incorrect position (see chapter 3.4), the drive unit cannot be switched on. Instead, the On/Off button [3] lights up green and the LED [c] in the display [2] flashes white.
Drive unit battery is empty
If the battery no longer has sufficient capacity, the LED [a] flashes briefly in the display [2] when the smoov is switched on. The system switches off completely thereafter. Charge the battery as described in chapter 4.1.
The control unit battery is empty
If the battery no longer has sufficient capacity, the LED [f] flashes briefly in the display [12] when the control unit is switched on. The system switches off completely thereafter.
Charge the battery as described in chapter 4.2.
Error in the system
In this regard, see the explanations in chapter 6.

|
---|---

Fault due to Bluetooth devices
Check that all Bluetooth devices in your vicinity are switched off.
If this is the case and there is still no connection established between the drive unit and control unit despite repeated attempts, please contact your specialist dealer.
3.2 Using the smoov
If the drive and control units are connected via Bluetooth, use of the smoov can commence. Note the following in this regard:

• The smoov can (from the user’s viewpoint) only move forwards; it cannot move backwards.
• The smoov is a drive for your wheelchair and does not have any braking functions. The push rims control the travel direction and braking of the wheelchair.
• Turning the speed dial [11] forwards sets the smoov in motion. The further you move the speed dial in the direction of travel, the faster your wheelchair will move.
• The speed dial [11] can be turned infinitely. However, once the maximum speed is reached, no further increase in speed is possible.
• To reduce the speed, you need to turn the speed dial against the direction of travel. The drive wheel [8] switches off if the value falls below the zero point. The smoov is then in freewheeling mode. However, the control unit remains switched on.
• To bring the wheelchair to a complete stop after switching off the drive, you need to brake it as usual using the push rims.

** The individual gradations of the speed wheel can be programmed individually via the smoov Mobility app. In this regard, please read the relevant explanations in the smoov Mobility app operating manual.
3.3 Emergency stop in hazardous situations**
Every wheelchair user is trained to bring their wheelchair to an immediate stop in hazardous situations by braking it using its push rims.
To bring your wheelchair to a quick and safe stop in hazardous situations when on a trip with the smoov, proceed as follows:

• Press the outer surface of the On/Off button [10]. This switches the drive wheel [8] of the drive unit to freewheeling mode. However, the control unit is not switched off; it remains switched on.
• Use the push rims to brake the wheelchair and bring it to a complete stop as quickly as possible.

ATTENTION – HIGH ACCIDENT RISK!
In the event of an emergency stop, if the drive wheel [8] on the drive unit is not switched to freewheeling mode via the On/Off button [10], your wheelchair is continuously pushed forward at the preset speed. It is therefore hardly brought to a stop when braking only with the push rims.
By pressing the On/Off button [10], neither the control unit nor the drive unit is switched off – as indicated by the illuminated LEDs. This means that the smoov is immediately set in motion again as soon as the speed dial [11] is turned (even unintentionally). In this respect, you should switch the drive unit off completely in the event of an emergency stop (see chapter 3.6.2) until it is safe for you to continue.
3.4 Cornering
When cornering, the drive wheel [8] swivels out of its centre position to the left or right. In this context, the speed is gradually reduced automatically and the drive unit is ultimately switched off. This is because there is a risk of the wheelchair tipping over if the user is cornering at too high a speed.
If the drive wheel is outside of its permissible position, the drive unit can no longer be switched on. The drive wheel cannot be switched on until the drive wheel has returned to a permissible position (diagram B).
During regular use, the On/Off button [3] on the drive unit lights up green and the display [2] indicates the capacity of the battery. Depending on the capacity of the battery, the LED [f] on the control unit’s display panel [12] lights up green, yellow or red. The LEDs [a] to [e] indicate the capacity of the battery.
If the drive unit is switched off due to excessive deflection of the drive wheel [8], the On/Off button [3] on the drive unit lights up green and the LED [c] flashes in white. Depending on the capacity of the battery, the LED [f] on the control unit’s display panel [12] lights up green, yellow or red. The LED [c] also flashes white.

|
---|---

Important safety information
In various situations, for example when navigating a tight bend from a standing position, it cannot be ruled out that the drive wheel [8] may turn 180 degrees. In this position, the drive is switched off and is therefore in freewheeling mode.
This incorrect wheel position (diagram A) can (primarily when navigating slopes) can result in regenerative braking. Consequently, severe damage to the smoov drive unit cannot be ruled out.
For this reason, make sure that the drive wheel [8] is always in the correct travel position (diagram B).
Warning – Risk of entrapment hands
Never reach between the housing and the forks of the drive wheel within the swivel range of the drive wheel [8].
Information about starting after a standstill and switching on the drive unit
Prior to activating the drive, check that the drive wheel [8] is correctly positioned in the direction of travel (diagram B). If it is not correctly positioned, you first need to move forward manually using the push rims. This makes the drive wheel swivel to the correct position automatically. The system can then be switched back on.

|
---|---

3.5 Range
For every smoov user, the range of the system is one of the areas of greatest interest. In general, the smoov has a range of up to 20 km with the standard built-in battery (6.2 Ah). These are ideal values and relate to flat, paved terrain. Deviations may occur due to topographical conditions, the ambient temperature, the road surface, the tyre pressure of the wheelchair wheels, the frame geometry, the weight of the wheelchair and the weight of the user.
3.6 Switching off the system
3.6.1 Control unit
The control unit is either switched on for drive mode or it is in standby mode. It is not possible to switch it off completely.

• Briefly pressing the On/Off button [10] or turning the speed dial [11] against the direction of travel (see chapter 3.2) switches the drive wheel [8] to freewheeling mode. The control unit remains switched on in this regard.
• If the On/Off button [10] is pressed and held for longer than 2 seconds, both the control unit and the drive unit are put into standby mode. All LEDs on the control unit go out and only the On/Off button [3] on the drive unit lights up green.
• The control unit automatically switches to standby mode if it is not used for 20 minutes. However, this does not have any effect on the drive unit.
• To put the control unit back into operation from standby mode, it needs to be switched on again (see chapter 3.1).

3.6.2 Drive unit
Standby mode

• The drive unit can only be put into standby mode by the control unit (see chapter 3.6.1).
• If the drive unit is in standby mode, the control unit needs to be switched back on in order to put the drive unit back into operation.
• If errors occur in standby mode or if the battery charge status falls below 10%, an error message or warning appears in the display [2].

Complete shutdown of the drive unit

• If the On/Off button [3] is pressed, the drive unit is switched off completely. The LED displays [2], the LED in the On/Off button [3] and the position light [7] go out. The shutdown is signalled by an acoustic signal.
• Automatic shutdown occurs after 1 hour (factory setting) if the drive unit does not receive a signal from the control unit during this time.
• If the drive unit is shut down completely, it can no longer be activated by the control unit. It needs to be switched on again (see chapter 3.1).

Shut the drive unit down completely in the event of prolonged standstill or an emergency stop. This is to prevent it from being switched on accidentally.
When travelling, particularly when travelling by plane, the control unit must be put into standby mode and the drive unit must be shut down completely!

Charging the batteries

4. 1 Charging the drive unit battery
First read the safety instructions for the charger and the charging procedure in chapters 11.3 and 11.4 before charging the smoov battery for the first time. With regard to the charging process, proceed as follows:

• Switch the control unit to standby mode (see chapter 3.6.1).
• Switch the drive unit system off completely (see chapter 3.6.1).
• Plug the power cable [19] of the charger into a socket. The LED [21] lights up blue; the LED [20] lights up orange.
• Insert the charging plug [18] into the charger socket [1]. The correct positioning and locking of the connection occurs automatically via a magnetic closure.
• The start of the charging process is now signalled by two brief acoustic signals.

During the charging process, the displays [2] (drive unit) and [12] (control unit (only if switched on)) indicate the current charge status of the drive unit battery as follows:

• LED [a] flashes: Battery capacity < 10%
• LED [a] lights up: Charge status > 10%
• LED [b] lights up: Charge status > 20%
• LED [c] lights up: Charge status > 40%
• LED [d] lights up: Charge status > 60%
• LED [e] lights up: Charge status > 80%

If the control unit is switched on, LED [f] continuously indicates the remaining battery capacity of the control unit.

The battery should always be fully charged. However, the charging process can be interrupted or terminated at any time if necessary.
When the charging process is complete, you must first disconnect the charging plug [18] from the charger socket [1], then disconnect the power cable [19] of the charger from the socket.
Attention: The drive unit is switched on after the charging process.
Displays on the charger
The status of the charger is indicated by its LED [20] as follows:

In addition, LED [21] lights up blue as soon as the charger is ready for use

The drive unit is switched on following completion of the charging process.
Only the Alber charger supplied with the smoov is to be used to charge the drive unit. The use of a charger not supplied by Alber is not permitted.
Ensure that the charger plug [18] and the charger socket [1] are clean and that there are no metallic particles. If there are any metallic particles, remove these with a clean, dry cloth.
Remove the charger once charging of the drive unit is complete. First remove the charging plug [18] from the charger socket [1] and then unplug the mains plug [19] from the mains socket.
Always check the charge status of the batteries before each use.
They should be fully charged prior to use.
If an error occurs when charging the drive unit, this is indicated by LED display [2] on the drive unit and by LED [12] on the control unit. The error is also indicated by acoustic signals (see chapter 6)
If the drive unit is on the wheelchair during charging, it is to be switched off completely before starting the charging process (see chapter 3.6.2) and the wheelchair is to be secured by means of its parking brakes to prevent it from rolling away inadvertently.
The battery should always be fully charged so that you are able to make use of the smoov’s maximum range. In addition, you reduce the risk of no longer being able to use your wheelchair with the motorised assistance of the smoov due to an empty battery.
4.2 Charging the batteries of the control unit
Alber does not supply a separate charger for the control unit and recommends charging it via the drive unit (see chapter 4.2.2). As the drive unit batteries are also charged during this process, the total charging time is longer. To charge only the control unit battery, you can use a charger which is available from electrical retailers. However, it is imperative that such a charger comply with the following technical parameters:

• Maximum +5 volt DC voltage
• Maximum 1.5 ampere current
• Charger cable: USB type C

Chargers with different technical parameters, in particular adjustable laboratory power supplies or power supplies with a higher voltage and power reserve, must not be used under any circumstances!
4.2.1 Charging with an external charger

• Switch the drive unit off completely by pressing the On/Off button [3]. This prevents the drive unit from rolling away if the control unit is actuated unintentionally.
• Open the cover [13] on the back of the control unit.
• Insert the charger cable into the charger socket [14].
• Carry out the charging process in accordance with the charger operating manual.

4.2.2 Charging via the drive unit

• Switch the drive unit off completely by pressing the On/Off button [3]. This prevents the drive unit from rolling away if the control unit is actuated unintentionally.
• Open the cover [13] on the back of the control unit and open the cover [5] on the drive unit.
• Insert the charger cable supplied with the Alber charger into the charger socket [14] on the control unit and into the USB-C socket [6] on the drive unit.
• Start the charging process on the drive unit as described in section 4.1.
• LED [f] on the control unit flashes green during charging.
• LED [f] lights up green continuously if the charging process is complete.
• Remove the charger cable; LED [f] goes out

If the charging process is complete and the charger cable has been removed, the smoov can be put back into operation

**** If only the two sockets are connected to each other without connecting the Alber charger to the drive unit, energy is withdrawn from the drive unit batteries in order to charge the control unit battery.

Capacity display of the batteries

If any error messages other than those listed here appear, there is a serious system fault. In such cases, the smoov cannot be used and must be sent to Alber GmbH via your specialist dealer for testing.

Automatic shutdown

If the control unit is not actuated for longer than 20 minutes (factory setting), it is automatically put into standby mode together with the drive unit (the LEDs go out). If the drive unit shuts down automatically if it is not used for one hour. As of this moment, there is no longer an active Bluetooth connection between the control unit and drive unit.
To put the system back into operation, the drive unit and control unit need to be switched on again (see chapter 3.1).

Pairing

Pairing is a process in which Bluetooth devices are paired with each other. With regard to the smoov, these devices are the drive unit and the control unit.
Both components are connected by radio and exchange characteristic data in this way.
They therefore recognise each other automatically during every start-up.
The drive unit and the control unit are already paired upon delivery of the smoov. In the event that the drive unit or control unit are replaced (within the Alber exchange pool for example), the components no longer recognise each other and need to be matched with each other by means of re-pairing as described below.

• Fully charge the batteries of the control unit and the drive unit (see chapter 4).
• Switch on the drive and control unit.
• Open the cover [13] on the control unit.
• Use a pointed object, such as a ballpoint pen, to press and hold the pairing button [15] for approx. 3 seconds.
• Hold the control unit close to the drive unit.
• Pairing now starts automatically. ALED [f] flashes blue on the control unit. LEDs [b] and [d] flash white. Button [3] lights up green on the drive unit; LEDs [b] and [d] flash white.
• Pairing is complete as soon as button [3] flashes blue on the drive unit.
• At this point, press button [3] briefly to complete pairing.
• Close the cover [13] on the control unit.

Your smoov is ready for use again if pairing was carried out successfully.

9.4 Important information about air transport
With regard to its technical design, the smoov, and specifically the lithium- ion battery contained therein, complies with the applicable standards, guidelines and laws. It meets the requirements of the International Air Transport Association (IATA) for air transport. We confirm this annually in the form of our transport certificate. This is prepared on the basis of the new IATA Dangerous Goods Regulations, which are not usually published until mid-December of each year. The current certificate is available for download on the Alber homepage: ( https://www.alber.de/de/hilfe-service/alber- service/reisen-mit-alber-produkten/ ). We would be happy to send it to you on request.
However, when planning a trip, please contact your travel agent or the airlines to discuss taking the smoov with you on any flight you may book. At the end of the day, the decision to allow or refuse the smoov on board is made at the pilot’s discretion. Neither Alber GmbH nor their specialist dealers are able to influence the pilot’s decision.
Please also note the applicable regulations for transporting lithium-ion batteries in the countries you are visiting (see also chapter 3.5.8).

Safety instructions and hazard information when using the smoov

10.1 General information

• Prior to use, check that the parking brakes of your wheelchair are working and are therefore able to prevent your wheelchair from rolling away inadvertently. If this is not the case, please contact your specialist dealer.
• Your wheelchair is driven by the drive unit and control unit. If the system is switched on, each actuation of the control unit is converted into a movement command (forward motion). It is not possible to move backwards.
• The wheelchair is steered and braked by its push rims during use.
• The speed is reduced via the control unit until it is switched off (see chapter 3.2).
• In the event of an emergency stop, the drive must first be deactivated or put into standby mode via the control unit. The wheelchair must then be brought to a stop via its push rims. Please read chapter 3.3 in this regard.
• We recommend that you have a user training session when you first receive your smoov. This will allow you to get used to the drive and everything you can do with it.

Information about user training

• Start your first attempts at using the smoov with caution, and start your user training on level ground.
• Take your user training in areas without any obstacles.
• Before using the smoov to navigate slopes or inclines, you should be able to operate the device safely on level ground.
• Always adapt your speed to external conditions so that you are able to stop your wheelchair or circumvent any obstacles that may suddenly appear, for example.
• Always navigate inclines with a fully charged battery. The drive wheel runs in freewheeling mode if the battery is empty; however, power assistance is no longer available for the rolling motion.
• The smoov must be switched off on slopes. Always navigate slopes at a reduced speed so that you are able to avoid any obstacles that suddenly appear and are able stop the wheelchair in time.
• Observe the information, safety instructions and hazard information provided by your wheelchair manufacturer. This also applies to using the smoov.
• It is imperative that you follow the instructions for cornering in chapter 3.4.

In the event of an emergency stop, you must be able to bring your wheelchair to an immediate stop at any time using its push rims. For this reason, adjust the speed to your physical capabilities and the respective usage situation.
Observe the following safety instructions and hazard information.
10.2 Safety instructions

• The drive unit must be completely switched off before being attached to the wheelchair, before being removed from the wheelchair, and before the user is moved into or out of the wheelchair (see chapter 3.6). The parking brakes of the wheelchair must also be applied.
• For safety reasons, you must switch the drive unit off completely and activate the parking brakes of your wheelchair when you stop, especially if you are on a slope or incline. This is to prevent your wheelchair from rolling away inadvertently.
• Always keep both hands close to the push rims so that you are able to spontaneously change the direction of travel and brake at any time.
• The drive unit and the control unit are to be switched off completely in potentially hazardous situations (see chapter 3.6).
• In the (unlikely) event of the drive unit or control unit battery overheating or catching on fire, you must ensure that these two components do not come into contact with water or  other liquids under any circumstances. The only suitable extinguishing agents recommended by the battery manufacturers are sand or a Class D fire extinguisher.

Before using the device:

• The smoov may only be attached to push rim wheelchairs that have been approved by Alber GmbH for this device.
• The brackets or adapter axles holding for the smoov may only be installed and modified by Alber GmbH or an Alber authorised specialist dealer.
•  When using the smoov, always strictly adhere to the operating manual for the wheelchair.
• Pairs of anti-tippers need to be fitted to the wheelchair in order to use the smoov. Use of the smoov without anti-tippers is not permitted.
• Prior to each use, check the condition of the drive wheel [8]. If the tyre has reached its wear limit (the tread is hardly visible), the smoov must not be used any further.
• Prior to each use, check that your wheelchair parking brakes are working correctly. It is forbidden to use the wheelchair without working parking brakes.
• Check the air pressure of the wheels of your wheelchair at regular intervals in accordance with the instructions and specifications of the wheelchair manufacturer. Insufficient air pressure can severely affect the handling and range of the smoov.
• The front wheels of the wheelchair must run freely. With regard to wheels with pneumatic tyres, observe the wheelchair manufacturer’s specifications for the required air pressure.
• Prior to each use, check that the drive unit is seated correctly in the adapter axle on your wheelchair.
• Prior to releasing the parking brakes and prior to activating the drive, check that the drive wheel is correctly positioned in the direction of travel (see also chapter 3.4). If it is not correctly positioned, you first need to move forward manually using the push rims and then switch on the drive.

When using the smoov, please note that:

• If you notice any unusual handling of your wheelchair or smoov at the start of use or during use, stop using the device immediately. Then contact your specialist dealer to have the problem corrected.
• Before using the smoov to navigate slopes or inclines, 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.
• Avoid steps and drops and keep a safe distance from them.
• If the drive unit is switched on, each actuation of the control unit is converted into a movement command. For this reason, when stopping or waiting in potentially hazardous areas (e.g. while waiting at a traffic light, on slopes, or on ramps of any type), take your hand off of the control unit and secure your wheelchair using its parking brakes.
• Never reach into a wheelchair wheel if the drive unit is switched on.
• Do not insert or throw objects of any kind into a wheelchair wheel.
• Never attach objects of any kind to the control unit. This could result in unwanted travel impulses.
• When navigating pavements, keep a safe distance from the kerb (preferably the width of the wheelchair).
• Avoid using the wheelchair on soft ground (e.g. loose chipping, sand, mud, snow, ice or deep puddles).
• The force of the drive unit is not to be underestimated. For example, if the drive wheel [8] “turns” on loose ground, parts lying on the ground (e.g. sand, stones, small pieces of wood, etc.) can be hurled backwards. Pay particular attention to this when there are persons behind your wheelchair.
• Never leave your wheelchair with the smoov attached to it unattended. This applies irrespective of whether the smoov is switched on or off.
• The smoov can be impaired by strong electromagnetic fields and, in rare cases, it may interfere with other equipment such as anti-shoplifting barriers in department stores.
• You must not use the smoov 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.
• When cornering and when navigating slopes, it is imperative that you follow the instructions in chapter 3.4.
• If you intend to stop in your wheelchair on a slope or incline, your wheelchair must be parked facing across this slope or incline (not up or down) and the parking brakes must be applied.
• When approaching inclines, the drive must first be activated, then the wheelchair’s parking brakes need to be released.
• After every trip or when your wheelchair is idle, activate the parking brakes to prevent the wheelchair from rolling away inadvertently.
• Never navigate across downhill slopes.
• Apply the smoov brake carefully according to your speed (i.e. not suddenly).
• The highest achievable speed with the smoov drive unit is 6 or 10 km/h respectively. If this value is exceeded (e.g. when navigating slopes), the drive unit switches to idling. In such cases, you need to reduce the speed with the push rims. The drive unit switches on again automatically as soon as the wheelchair drops to a speed below the previously driven/set speed.
• If you use your wheelchair as a vehicle seat, the statutory provisions and regulations are to be observed in this regard as well as the information and specifications of the wheelchair manufacturer. The drive unit and control unit are always to be removed from the wheelchair and stored safely.
• When travelling in a vehicle, secure your wheelchair and the smoov according to the current applicable statutory requirements and legislation.
• When navigating public roads and pavements in the Federal Republic of Germany, the provisions of the German Road Traffic Regulations and the Road Traffic Licensing Regulation are to be observed at all times. In other countries, the locally applicable national provisions are to be observed at all times.
• The smoov is only intended for transporting persons with restricted mobility and must not be used for any other purpose, e.g. for transporting goods or as a plaything for children.
• The operation of the smoov is prohibited in the vicinity of strong magnetic fields, such as those induced by holding solenoids, transformers, tomographs, etc.
• Avoid using the smoov in adverse conditions, such as storms, hail and high undergrowth.

Pairs of anti-tippers need to be fitted to the wheelchair in order to use the smoov.
Use of the smoov without anti-tippers is not permitted.
When the wheelchair is at a standstill, switch the system off completely (see chapter 3.6.2) and apply the parking brakes of your wheelchair. This prevents the smoov from moving away unintentionally and prevents the wheelchair from rolling away unintentionally, especially on slopes.
After using the smoov, please note the following:

• When not in use, switch the drive unit off immediately and completely in order to avoid any accidental triggering of a travel impulse.
• Whenever the wheelchair is at a standstill, apply the parking brakes.
• Recharge the battery of your smoov as soon as possible after each use.

10.3 Obstacles
When overcoming obstacles, observe the wheelchair manufacturer’s instructions in this regard. It is possible to overcome obstacles with a maximum height of 50 mm with the smoov.
Overcome obstacles (e.g. kerbs) in a forward motion and at right angles to the obstacle. Raise the front part of your wheelchair slightly and then let the smoov push slowly.
It is up to you to decide whether to enlist the help of another person.
10.4 Hazardous areas and hazardous situations

• Potential hazardous areas may only be accessed if the drive unit is completely switched off.

• The wheelchair user must decide in each case whether it is safe to navigate the intended route based on factors such as their skill level and their physical strength.

• Prior to use, the wheelchair user is to check the condition (remaining tread, damage) of the smoov drive wheel [8]. The charge status of the batteries and the functionality of any visual and acoustic signalling devices attached to the wheelchair are also to be checked.

• These safety checks and the personal experience of the wheelchair user are of particular importance in or near the following hazardous areas, the navigation of which is left to the judgement and risk of the wheelchair user:
  – Quay walls, berths and marinas, paths and areas near water, bridges and dykes without railings
  – Narrow footpaths, gradients (e.g. ramps and driveways), narrow paths along slopes, mountain paths
  – Narrow and/or steep/inclined paths along main and side roads or near precipices
  – Paths covered with leaves, snow or ice
  – Ramps and lifting equipment on vehicles

• With regard to foreseeable hazardous situations, the drive needs to be switched off by switching off the control unit (see chapter 3.6.1).

When cornering or turning the wheelchair on inclines or slopes, the centre of gravity of the wheelchair may be shifted leading to a risk of the wheelchair tipping over. As such, carry out these manoeuvres with increased caution, not abruptly, and only at a slow speed!
Proceed with special caution when navigating ramps or lifting platforms of vehicles. The drive unit must be switched off completely during navigation and during the lifting or lowering process of the ramp or lifting device. The parking brakes on the wheelchair must also be applied. This prevents the wheelchair from rolling away due to inadvertent movement commands, for example.
Wheel grip may be poor if the ground is wet; there is a greater risk of slipping. Adapt your navigation technique accordingly and never use the device if the tyres are worn.

Battery (installed in the drive unit and control unit)

Maintenance-free, rechargeable lithium-ion batteries are integrated in the drive unit and control unit. For safety reasons, these cannot be removed by the wheelchair user. If necessary, they must be removed by your authorised specialist dealer and be replaced by new batteries.
Read and observe the following safety instructions and precautions prior to starting up the smoov and prior to the charging process. Failure to comply with the safety precautions and instructions may damage the product or result in electric shock, fire and/or serious injuries. The lithium-ion batteries contain chemical substances, which may cause hazardous reactions if the safety instructions specified here are disregarded.
