Starting up

Read the operating instructions fully before you start work on the installation of the robot lawn mower. The quality of the installation work has a direct eﬀ ect on the mowing results.

5.1 How it works
Follow the operating instructions carefully in order to ensure that the robot lawn mower works correctly and safely.
The robot lawn mower chooses its direction on a random basis. The entire garden gets mowed by the robot lawn mower reaching all areas that are not blocked oﬀ by boundaries and obstacles. When the robot lawn mower discovers that it has reached a lawn boundary or recognizes an obstacle, it will change its direction and mow in a diﬀ erent random direction. Using sensors the robot lawn mower can distinguish between obstacles and lawn areas, enabling it to move freely within its work area.

The robot lawn mower has a camera unit which generates and processes images of the area lying ahead. On this basis the area lying ahead is examined as to whether it is an area for mowing or a lawn boundary or an obstacle. If the area lying ahead is assessed as being an area for mowing, the robot lawn mower will move straight ahead with the mower unit activated. If the area lying ahead is assessed as being a lawn boundary or an obstacle, the robot lawn mower will stop, check again for an area for mowing and continue mowing in a random direction. The area for mowing must be checked and adapted carefully so that the robot lawn mower has enough room to recognize where it ends. The lawn boundaries must be clearly deﬁ ned so that the robot lawn mower can recognize them within its reaction time.

The purpose of the laid guide cable (24) is to get the robot lawn mower to dock punctually in the charging station (19); it does not set any limits during mowing. It is imperative therefore for the robot lawn mower to be on a lawn area with clear optical or physical limits. For the robot lawn mower to ﬁ nd the guide cable (24) and subsequently the charging station (19) it must be in the charging station (19) when mowing mode is started for the ﬁ rst time. It uses a global navigation satellite system (GNSS) to determine the position of the charging station (19). If the position of the charging station (19) is ever changed, it is essential for the robot lawn mower to be placed again in the charging station (19) for calibration. Make sure that there is no shielding or rooﬁ ng which could prevent the positioning operation. Avoid placing the charging station (19) near high buildings. Under some circumstances calibration might fail In such cases due to a poor signal.

When the battery charge level is low, the robot lawn mower will return to the charging station (19). With the help of the GNSS module the robot lawn mower will determine its distance from the charging stations (19) and look for it. If the robot lawn mower comes up against a garden boundary or any obstacles on its way to the search loop, it will save its position and the mowing area will be mapped. This will help the robot lawn mower to return to the charging station (19) faster in future use. When the robot lawn mower arrives at the guide cable (24) it will return to the charging station (19) using its wire recognition sensors. This can take several minutes depending on the garden’s size and complexity.

The global navigation satellite system (GNSS) is also used to acquire location-speciﬁ c sunrise and sunset data. There must be suﬃ cient daylight for the robot lawn mower to work properly. Check the lens of the camera unit (15) regularly for signs of dirt.

5.2 Sensors
The robot lawn mower is equipped with a number of safety sensors. These sensors enable the robot lawn mower to move within its mowing area.

Lifting sensor:
If the robot lawn mower is raised at the back by more than 30° from the ground or if a front wheel (12) loses contact with the ground, the robot lawn mower and the rotation of the blades (10) will be stopped immediately.
Tilting sensor:
If the robot lawn mower tilts severely in any direction, the robot lawn mower and the rotation of the blades (10) will be stopped immediately.
Obstacle sensor:
The robot lawn mower is able to detect obstacles in its path. If the robot lawn mower collides with an obstacle, the robot lawn mower and the rotation of the blades (10) will be stopped immediately and the mower will reverse away from the obstacle.
Camera unit:
The robot lawn mower comes with a camera unit (15) which analyzes the mowing area (approx. 1m²) lying ahead of it. The camera is directed at the ground so that the objects lying in the screen area appear with a maximum height of 50 cm.
The image materialto be processed is saved only locally and temporarily on the robot lawn mower and is continually overwritten.
The robot lawn mower can recognize obstacles and the work area in which there is no longer any lawn. When the robot lawn mower comes across an obstacle or no longer detects any lawn, it will stop and begin to mow again in a random direction.
Because of the camera unit it is impossible for the robot lawn mower to work in twilight or during the night. The selected work window should lie within daytime hours when there is enough daylight for the robot lawn mower to work reliably. This also helps to protect seminocturnal animals such as hedgehogs.
Distance sensors:
The robot lawn mower is equipped with distance sensors (16) which enable it to detect obstacles along its path. When the robot lawn mower comes across an obstacle, it will stop and begin to mow again in a random direction.
Magnetic tape sensor:
The robot lawn mower is equipped with a magnetic tape sensor for recognizing a magnetic tape (27) lying on the ground. When the robot lawn mower comes across a magnetic tape it will stop and begin to mow again in a random direction. The magnetic tape serves as a virtual boundary for creating areas of the garden where the robot lawn mower is not allowed to mow.
Rain sensor:
The robot lawn mower is equipped with a rain sensor (5) to prevent it from operating in the rain. When the robot lawn mower detects rain it will return to the charging station (19) and and be completely recharged there. When the rain sensor (5) is dry again, the robot lawn mower will begin working again provided it is still in an active time window. When the rain sensor (5) is triggered, the rain sensor LED (53) will light up. Do not short-circuit the two metal sensors with metal or any other conductive material.
This will impede the correct operation of the robot lawn mower.
GNSS module:
The robot lawn mower determines its position and the position of the charging station (19) by means of a global navigation satellite system (GNSS). This helps the robot lawn mower to ﬁ nd its way back to the charging station (19). The robot lawn mower can use the GNSS module to determine the local times for sunrise and sunset so that it is prevented from mowing in twilight and during the night. This also means that the robot lawn mower can work reliably with its camera unit (15).

The robot lawn mower also uses the GNSS module at all times to determine its distance from the charging station (19). The robot lawn mower is allowed to move no more than 1000 m from the charging station (19) or else the GNSS LED (54) will turn yellow and the robot lawn mower cannot be operated in Main Area mode. The mower’s distance from the charging station (19) is irrelevant for operation in Secondary Area mode.

5.3 Preparations
If the grass is taller than 60 mm it has to be shortened ﬁ rst to avoid exposing the robot lawn mower to excessive load and adversely aﬀ ecting its operating eﬃ ciency. Use a conventional lawn mower or trimmer to do this. Remove all loose objects from the lawn which could get damaged by the robot lawn mower or cause damage to the robot lawn mower itself.
Check the mowing area, the lawn boundary and any areas that you don’t want to be mowed. The following sections of these operating instructions contain information about how you can deﬁ ne precise lawn boundaries and protect speciﬁ c areas. Some obstacles can be detected by the robot lawn mower in good time and require no elaborate protection. Have the following tools ready: A hammer, tongs, a wire stripper and a spirit level (optional).

5.3.1 Calculating the gradient of the lawn
The robot lawn mower can cope with gradients of up to 25%. You therefore need to avoid steeper gradients. The gradient can be determined on the basis of height divided by distance (Fig. 3a).
Example: a/b = 25 cm/100 cm = 25 %

5.3.2 Installing the battery
A battery (A) from the Power-X-Change series is needed to operate the robot lawn mower. Important: Depending on the model of your robot lawn mower, it might not come complete with the battery (A). Open the battery compartmentcover (9).
Press the pushlock button of the battery (A) and push the battery (A) into the mount provided. Close the battery compartment cover (9) and make sure that it latches in place correctly (Fig. 3b).
To remove the battery (A), open the battery cover (9).
Press the pushlock button of the battery (A) and pull out the battery (A).

5.4 Charging station
5.4.1 Position of the charging station Begin by determining the best position for the charging station (19).
You need an outdoor socket outlet with a permanent supply of electricity so that the robot lawn mower works at all times. The charging station (19) must be placed on a ﬂ at area on level with the turf. Make sure that the area is ﬂ at and dry. Ideally you should position the charging station (19) at the edge of the mowing area. Please note that the power cable for the charging station (19) should not be laid inside the mowing area. If it is, it will need to be buried to avoid it being damaged by the robot lawn mower. Position the charging station (19) together with the guide cable (24) on an open area free of obstacles which is as accessible as possible from all directions. Avoid positioning the charging station (19) in hard-to-reach corners or in areas that can be reached only through bottlenecks. The maximum distance from the charging station (19) to a lawn boundary is not allowed to exceed 1000 m. This serves to reduce the risk of theft. At greater distances the GNSS LED (54) will turn yellow and the robot lawn mower cannot be operated in Main Area mode. The mower’s distance from the charging station (19) is irrelevant for operation in Secondary Area mode. To guarantee efﬁ cient and automatic mowing it is recommended to restrict the distance from the lawn boundary to the charging station (19) to 50 m. As the distance from the charging station (19) increases, it is possible that the robot lawn mower will no longer have enough battery power for it to return to the charging station (19). Use a battery with greater capacity for larger mowing areas. Select a position in the shade because it is best to charge the battery in cool surroundings. Tall buildings or trees can weaken the GNSS signal so that the robot lawn mower is no longer able to ﬁ nd its way back to the charging station (19) automatically. It is important therefore to keep a reasonable distance away from tall buildings and trees and to make sure that the charging station (19) lies under the open sky. Also note that the guide cable (24) must be laid in a straight line for least 1 m in front of the charging station (19) and for at least 0.5 m behind the charging station (19) (Fig. 4a). Curves immediately in front of the charging station (19) could cause problems when docking for charging.

5.4.2 Localization of the charging station
When the battery is almost empty, the robot lawn mower will return to the charging station (19) by following the guide cable (24). The robot lawn mower compares its actual position with the calibrated position of the charging station in regular intervals with the help of GNSS. The robot lawn mower travels in the direction of the charging station (19) and looks for the guide cable (24) in several steps.
As it does so, the robot lawn mower stops now and again before setting oﬀ if necessary in a diﬀ erent direction in order to reach the guide cable (24). When the robot lawn mower gets near to the guide cable (24) it will begin to detect its position with the help of rotary movements and the strength of the signal transmitted by the guide cable (24). If the robot lawn mower comes across an obstacle or a lawn boundary while mowing, this position will be saved. The map produced as the result helps the robot lawn mower to ﬁ nd the charging station (19) more quickly. When the robot lawn mower reaches the guide cable (24) it will follow it counter-clockwise to the charging station (19). Make sure, therefore, that the charging station (19) faces in the right direction when you position it (Fig. 4a).

5.4.3 Connecting the charging station to the power supply unit

Before you connect the charging station (19) to the power supply, check that the mains power supply is 100-240 V at 50/60 Hz.
Connect the power supply unit (20) directly to a socket outlet. Do not use the cable for any other use.
Do not use the power supply unit if it is damaged (20). In the event of any damage to cables or the power supply unit (20), contact an authorized professional immediately for replacement.
Do not charge the robot lawn mower in a damp location. Do not charge the robot lawn mower at temperatures above 40°C or below 5°C.
Keep the robot lawn mower and the power supply unit (20) away from water, sources of heat and chemicals. Keep the cable of the power supply unit (20) away from sharp edges in order to prevent damage.
Connect the power supply unit (20) to the charging station (19) (Fig. 4b).
With the main switch (7) set to ON and with a battery inserted, place the robot lawn mower in the charging station (19) and charge it fully before you use it for the ﬁ rst time.

5.4.4 Information about charging
The robot lawn mower will return to the charging station (19) in each of the following situations:

You send the robot lawn mower back manually.
The battery charge level drops below 30%.
The end of the daily work time has been reached.
The rain sensor has tripped.
The robot lawn mower has become overheated.
When twilight falls, making it impossible for the camera unit to work correctly.
In this case the robot lawn mower looks for the guide cable (24) and then travels automatically clockwise along the guide cable (24) as far as the charging station (19).
While the battery is being charged, the battery LED (55) of the robot lawn mower will ﬂ ash green.
When the battery is fully charged, the battery LED (55) and the LED display (19a) at the charging station (19) will light up green. Once it has been fully charged, the robot lawn mower will resume operation or remain in the charging station (19) until the next work time window.
If there is an obstacle on the guide cable (24) during the trip back to the charging station (19), the robot lawn mower will come to a stop in front of the obstacle after several attempts and will not be able to get back to the charging station (19).
Remove all obstacles on the guide cable (24).
If the temperature of the battery exceeds 45 °C, charging will stop in order to prevent damage to the battery. Charging will resume automatically once the temperature has dropped again.
If the temperature of the robot lawn mower controller exceeds 65 °C, the robot lawn mower will return to the charging station (19). Operation will resume in accordance with the settings once the temperature has dropped again. If the battery becomes empty before the robot lawn mower has returned to the charging station (19), the robot lawn mower will be unable to start up again. Bring the robot lawn mower back to the charging station (19) and leave the main switch (7) switched on.
The robot lawn mower will be charged up automatically.

5.5 Guide cable
IMPORTANT! A severed guide cable and any consequential damages are not covered by the warranty!

5.5.1 Laying the guide cable
The guide cable (24) can be laid both on the ground and in the ground. The fastening pegs (23) might break while they are being hammered into hard or dry ground. If the ground is very dry, water the lawn before installing the guide cable (24).

Installation on the ground Lay the guide cable (24) securely on the ground and fasten it with the supplied fastening pegs (23).
You can adjust the position of the guide cable (24) during the ﬁrst weeks of using the robot lawn mower. In the course of time, however, the guide cable will become overgrown with grass and will be no longer visible. Install the guide cable (24) with a maximum distance of 1 m between the fastening pegs (23).
Avoid situations in which the guide cable (24) is not actually lying on the ground.
Make sure that the guide cable (24) cannot be severed by the robot lawn mower.
While the robot lawn mower is mowing, it will travel with its activated mower unit over the guide cable .
Installation in the ground Bury the guide cable (24) in the ground at a depth of up to 5 cm. This will prevent damage to the guide cable (24) during for example scarifying or aeration.

Important!
Because the guide cable (24) is not always laid along the lawn boundary, it is important to make a note of where the guide cable (24) is positioned so that it is not damaged during future garden projects. Make a drawing or take photos to document the arrangement. If the guide cable (24) is not buried in the ground you should not scarify or aerate near the guide cable (24) so as to avoid damaging it.
5.5.2 Installing the search loop

The guide cable (24) forms a search loop which is used by the robot lawn mower to find its way back to the charging station (19).
Lay the guide cable (24) in a straight line for least 1 m in front of the charging station (19) and for at least 0.5 m behind the charging station (19) (Fig. 4a). Curves immediately in front of the charging station (19) could cause problems when docking for charging.
The guide cable (24) should enclose a minimum area of 5 m² (Fig. 4a). It is recommended to use the entire length of the guide cable (24) and to lay it in the shape of a square as far as possible.
The search loop should be orientated so that the robot lawn mower is well able to get to the charging station (19) from any point in the garden.
The distance between two guide cables (24) should amount to at least 0.8 m (Fig. 4a).
The guide cable (24) is not allowed to cross over itself.
Make sure there are no obstacles on the guide cable (24).
Make sure there are no obstacles within a distance of approx. 30 cm to the left and right of the guide cable (24) (Fig. 4c).
Keep away from the garden boundary and from overly high paving stones. If the path runs at ground level with the lawn you can lay the guide cable (24) there without leaving a gap.

5.6 Connecting the charging station
Finish laying the complete guide cable (24) before you connect it to the charging station (19). Use a wire stripper to remove a length of 10 to 15 mm of the insulation from the ends of the guide cable (24) for connecting to the charging station (19). Pull out the power plug before you connect the guide cable (24) to the charging station (19). The end of the guide cable (24) laid to the front side of the charging station (19) must be run to the back via the cable holders on the underside of the charging station (19). Check that this end is fastened securely to the charging station (19) and is connected to the left black connector.
After the guide cable (24) has been laid, pass the free end through the hole and connect it to the red connection on the right (Fig. 4d).
Important! The guide cable (24) is not allowed to cross over itself!
Then connect the power supply. When the installation is completed correctly, the LED display (19a) on the charging station (19) should light up green permanently. If the LED does not light up, check the connections ﬁrst.
If the LED lights up green but not permanently, read the table entitled “Display on the charging station and troubleshooting” at the end of these operating instructions.

5.7 Mowing area – Obstacles and mowing area boundaries
5.7.1 Lawn boundary
The mowing area must have a precise and fully enclosing lawn boundary. Familiarize yourself with the possibilities for deﬁ ning a lawn boundary as described in this section. Then start at any point of the lawn boundary with an examination of the garden boundary and follow the boundary in a circle until you arrive back at your starting point. Any sections of the work area that you want to exclude must be enclosed likewise with a precise lawn boundary. Proceed in the same way as for the outer boundaries of the mowing area.

Bottlenecks If the lawn area has a bottleneck, your robot lawn mower will be able to operate there as long as the corridor has a width of at least 1.2 m and a maximum length of 8 m (Fig. 5a). In the case of long and narrow bottlenecks, the robot lawn mower might no longer be able to ﬁ nd its way back to the charging station (19).
Distance from the lawn boundary When the robot lawn mower approaches the lawn boundary, this will be detected by the camera unit (15) at the front of the robot lawn mower. The lawn-free distance should amount to at least 30 cm (Fig. 5b). Check that there is no diﬀ erence in height at the lawn boundary as the robot lawn mower might travel beyond the exact lawn boundary before it stops and sets oﬀ again in a diﬀ erent direction. Deeper lying garden beds or elevated paving edges might result in damage to the robot lawn mower. Check the lawn boundaries regularly because if they become overgrown this could result in the robot lawn mower leaving the mowing area. It is also possible for the lawn boundary to be edged in with ﬂ at path stones to create a clear separation from the mowing area.
Lawn boundary with water As a general rule the robot lawn mower will reliably recognize the lawn boundary as described above. However, given the possibility that the robot lawn mower will overrun the lawn boundary we recommend a gap of approx. 50 cm between the lawn boundary and any water feature (a pond, pool, etc.) (Fig. 5c). Alternatively we recommend isolating the water feature with a raised all-round edge in order to protect the robot lawn mower more reliably.
Lawn boundary with a raised edge higher than 25 cm The robot lawn mower can use the distance sensors (16) to recognize obstacles with a minimum height of 25 cm (Fig. 5d). You can also use high obstacles to demarcate your lawn boundary. The robot lawn mower will stop at a distance of approx. 20 cm in front of the obstacle and turn so that it can continue mowing in another direction. Important! – This means that the robot lawn mower does not mow as far as the lawn boundary but leaves an area of approx. 20 cm unmowed.
Lawn boundary with a raised edge higher than 10 cm
The robot lawn mower can use the collision sensors to collide with obstacles below 25 cm. This function can also be used to deﬁ ne a lawn boundary. In this case make sure that the edging is sturdy and at least 10 cm high (Fig. 5e).

5.7.2 Obstacles
Obstacles are objects situated in the mowing area. The robot lawn mower can recognize many obstacles by means of the sensors. Soft, unstable and valuable objects must be protected where necessary. See the possibilities described above for separation from the lawn boundary.

Obstacles with a height over 25 cm (Fig. 5f) Solid obstacles which are over 25 cm in height and have a minimum width of 3 cm, e.g. trees, walls, fences, garden furniture, etc., are detected by the distance sensors (16). If the robot lawn mower comes up against an obstacle, it will stop and continue mowing in a diﬀ erent direction. In this case the area stretching approx. 20 cm to the obstacle will not be mowed.
Obstacles with a height under 25 cm (Fig. 5g) If an obstacle is not recognized by the distance sensors (16), the robot lawn mower will collide with the obstacle and trigger the collision sensors. The robot lawn mower will stop and continue mowing in a diﬀ erent direction. The obstacles must have a height of at least 10 cm. Protect sensitive and unstable objects with all-round edging.
Stones and low obstacles under 10 cm Stones, rocks and low obstacles of less than 10 cm in the mowing area need to be protected because otherwise the robot lawn mower could run over them. If not, this could result in the robot lawn mower getting damaged or blocked. (See the section “Lawn boundary”). The robot lawn mower treats trees as obstacles. However, where any tree roots project above the ground to a height of less than 10 cm, the area in which they are located needs to be protected. This will prevent damage to the roots and to the robot lawn mower.

5.7.3 Magnetic tape (Fig. 5h-j)
Obstacles such as fences and hedges which poorly reﬂ ect the distance signal transmitted by the robot lawn mower are not detected in part or only very late. Obstacles with a weak optical contrast relative to the mowing areas can also be diﬃ cult to recognize. Such areas can be protected by magnetic tape (27) as a safe and contact-free means of getting the robot lawn mower to change its direction.
The magnetic tape (27) serves as a mobile and temporary boundary in the mowing area. The magnet sensors installed in the robot lawn mower detect the magnetic tape (27) and turn away at its limits. In this way you can separate oﬀ parts of the garden which are oﬀ limits, for example:

Short-term separation of a part of the garden for a garden party where the robot lawn mower is not llowed to enter.
Placement of a trampoline or swimming-pool in the mowing area over the summer months. • A recently planted tree is still very sensitive and is best protected at an early stage from collisions with the robot lawn mower.
A seasonal flower meadow is planned to attract insects. This area is off-limits for the robot lawn mower and needs to be protected from the outset.
A new lawn has been sown in one area and you want to protect this area initially. The subsoil is still not firm and you want to wait for strong turf to form.

Lay the magnetic tape (27) a few centimeters away from the area or object in question. Shorten the magnetic tape (27) to suit your requirements (50 cm minimum length). To enable a boundary made up of several magnetic tape elements to be recognized reliably, the maximum distance between the respective ends should not exceed 8 cm (Fig. 5k). Make sure that the outer boundary of the mowing area is deﬁ ned by an optical or physical separation. Fasten the magnetic tape (27) to the ground by means of pegs (23) spaced a maximum of 1 m apart. Keep a distance of at least 80 cm away from the guide cable (24) and between two independent boundary areas so that the robot lawn mower can travel through without diﬃ culty. (Fig. 5l). Avoid laying the magnetic tape (27) on gradients because in such cases there is a risk of the robot lawn mower slipping out over the boundary area and the boundary not being recognized. Like the guide cable (24), the magnetic tape (27) can be installed both on the ground and at a depth of approx. 5 cm in the ground. Take care not to lay the magnetic tape (27) too deep in the ground because then there is no longer any guarantee that it will be recognized by the robot lawn mower.

5.7.4 Main area and secondary area (Fig. 5m)
A secondary area (B) refers to a work area that is not directly connected to the main area (A), e.g. a bottleneck. The robot lawn mower cannot reach a secondary area directly and independently.
To be able to mow the secondary area (B) you must carry the robot lawn mower manually into the secondary area (B). The robot lawn mower must be switched on with the main switch (7). Start the robot lawn mower there by pressing the “START A/B” button (64) for 5 seconds. Then close the control panel cover (13). Secondary area mode is activated and the status LED (52) will ﬂ ash green.
When the robot lawn mower is in the secondary area (B) it will not try to return to the charging station (19) if the battery charge level is low. The robot lawn mower will mow until the battery is empty. Then you must either charge the battery or carry the robot lawn mower back to the charging station (19).

Important!
The robot lawn mower is allowed to move no more than 1000 m from the charging station (19) or else the GNSS LED (54) will turn yellow and the robot lawn mower cannot be operated in Main Area mode. The mower’s distance from the charging station (19) is irrelevant for operation in Secondary Area mode.

5.7.5 Distance from mowed areas not belonging to you
Keep away from mowed areas which do not belong to you but to your neighbors, for example, and which are operated with a perimeter wire.
The signal produced by the perimeter wire can lead to problems when your robotlawn mower tries to ﬁnd its way back to its charging station.
5.8 GNSS module
5.8.1 Calibrating the position of the charging station
The robot lawn mower must calibrate the position of the charging station (19) with the help of a global navigation satellite system (GNSS) in order to ﬁ nd its way back to the search loop and to the charging station (19).
For this purpose you must place the robot lawn mower in ready-to-use condition and with the main switch (7) activated in the charging station (19). The GNSS LED (54) will ﬂ ash green during the calibration process and will light up green continuously as soon as the calibration is ﬁ nished successfully. This process can take several minutes.
Make sure that there is no shielding or rooﬁ ng which could prevent the positioning operation.
Avoid placing the charging station (19) near tall buildings.
Keep a reasonable distance away from tall buildings and trees. Under some circumstances calibration might fail due to poor signal coverage.

5.8.2 Mapping
When the robot lawn mower needs to return to the charging station (19), it determines its distance to the charging station (19) with the help of the GNSS module. If the robot lawn mower comes up against a garden boundary or any obstacles on its way to the charging station (19), it will save its position and the mowing area will be mapped.
This will help the robot lawn mower to return to the charging station (19) faster in future use.

5.8.3 Deleting the maps
To delete all the GNSS data on your robot lawn mower, switch oﬀ the robot lawn mower with the main switch (7) (OFF). Press the lock button (62) and keep it pressed while you simultaneously switch on the robot lawn mower with the main switch (7) (ON). The robot lawn mower will issue an acoustic signal to conﬁ rm deletion. Then you must restart the robot lawn mower in the charging station (19) in order to recalibrate the loading station’s position. If you carry out any major alterations to the mowing area in your garden it is recommendable to delete the robot lawn mower’s mapping. Particular during hot summer months, a large number of yellowed lawn patches could have a detrimental eﬀect on the way the robot lawn mower works. In such cases we recommend you to refrain from using automatic mode and to switch instead to using secondary area mode in suitable parts of the garden.
However, this might also lead to corruption of the mapping so that the robot lawn mower is no longer able to work correctly. In such cases: delete the mapping.
5.9 Garden boundaries and their quality To ensure that your robot lawn mower works safely without a perimeter wire, the robot lawn mower uses the camera unit (15) to check the boundaries of the mowing area.
The camera unit (15) analyzes the mowing area lying ahead of it (approx. 1m²). If the robot lawn mower comes up against a boundary of the mowing area, it can use various parameters to determine a boundary quality value.

5.9.1 Initialization run – getting started
Make sure that the robot lawn mower’s battery is fully charged at the beginning of the initialization run. Then the robot lawn mower can complete the deﬁ nition of a reference value in one operation. If one battery charge is not enough for the initialization run, the robot lawn mower will automatically return to the charging station (19) and continue its run after charging. For the reliability of the mowing area boundaries to be determined, an individual reference value per mowing area must be created for the robot lawn mower’s operation. To determine the reference value the robot lawn mower moves as usual in a random direction within the mowing area. If the robot lawn mower comes up against a boundary or an obstacle, it will stop and evaluate the mowing area ahead of it. Then the robot lawn mower will start moving again in a random direction. For safety reasons the initialization run takes place with the mower unit switched oﬀ .

If the robot lawn mower comes up against a boundary of the mowing area, this boundary will be evaluated and the guide cable LED (56) will light up. Green signals a reliable boundary of the mowing area and yellow an unreliable boundary. The robot lawn mower indicates the quality of a lawn boundary both in the initialization run and during automatic mode. For reliable determination of the reference value you need at least 200 contacts with a boundary of the mowing area. The boundary quality value is checked for its reliability after more than 200 contacts. If the robot lawn mower decides that the value is not yet reliable enough, it will continue its initialization run for a further 200 contacts. If the initialization run was successful so that it was possible to create a reliable boundary quality value, the robot lawn mower will begin to mow the mowing area in accordance with its mowing time setting.

If there was no success in creating a reliable reference value, the robot lawn mower will stop and the guide cable LED (56) will ﬂ ash red. Check the boundaries of the mowing area and correct the boundaries which do not diﬀ er clearly from the mowing area. Make sure that the mowing area differs clearly from the surrounding area. Now delete the existing reference value (see 5.9.4) and then repeat the initialization.

5.9.2 Checking the boundary’s quality in operation When the robot lawn mower is in automatic mode, it checks in regular intervals whether the current boundary quality value of the mowing area has changed compared to its reference value. As soon as the robot lawn mower is in the charging station (19), the corresponding status of the last determined comparative boundary quality value will be displayed via the guide cable LED (56).
This value is compared at the same time with the reference value determined during the initialization run.

The guide cable (56) lights up green:
The robot lawn mower is situated in the charging station (19) or near the search loop and the deviation from the reference quality value is small.
The guide cable (56) ﬂ ashes yellow:
The robot lawn mower is situated in the charging station (19) or within the search loop and the deviation from the reference quality value has worsened.
The guide cable LED (56) ﬂ ashes red:
The robot lawn mower is situated in the charging station (19) or inside the search loop and the deviation from the reference quality value is too big. The robot lawn mower stays in the charging station (19). Check the boundaries of the mowing area. Then delete the reference value (see 5.9.4) and carry out a new initialization of the boundary quality value.

The guide cable LED (56) is OFF:

The guide cable (24) is not connected correctly or has been damaged.
The power supply to the charging station (19) has been interrupted.
The robot lawn mower is situated outside the search loop.

5.9.3 Operating the robot lawn mower in secondary areas
The robot lawn mower can create an individual value for the main area and the secondary area.
This means that you must carry out an initialization run in each new secondary area.
You are only allowed to use the robot lawn mower on one secondary area. If you want to mow with the robot lawn mower on an additional secondary area it is absolutely essential to delete the boundary quality value of the secondary area and to carry out an initialization run.

5.9.4 Deleting the values
If the last time you mowed was ages ago, e.g. at the end of the previous season, the boundary quality values might have changed in the meantime. This could lead to mistakes when the new season gets underway. It is recommended therefore to delete the boundary quality value every year at the beginning of the season and to determine a new reference value.
This can help to guarantee that the robot lawn mower works safely and reliably.
The robot lawn mower must be in locked mode.
The lock LED (51) will then ﬂash red permanently.
To lock the robot lawn mower you must press the lock button (62).
Proceed as follows to delete the values saved for the corresponding areas:

Reference value of the main area (A): Press the “OK” button (63) and the “10H” button (60) simultaneously and hold for 3 seconds. An acoustic signal will sound. Place the robot lawn mower in the charging station (19) and restart it in order to carry out a new initialization run.
Reference value of the secondary area (B): Press the “OK” button (63) and the “8H” button (60) simultaneously and hold for 3 seconds. An acoustic signal will sound.

5.10 Switching on and checking the installation
5.10.1 Checking the installation of the guide cable and the charging station (Fig. 6a)
As soon as the LED display (19a) on the charging station (19) lights up green, the mowing area is ready for the robot lawn mower. First check that all the fastening pegs (23) for the guide cable (24) have been fully tapped in.
Place the robot lawn mower in the search loop a short distance behind the charging station (19). To check as far as possible the complete distance of the guide cable (24): The robot lawn mower should not yet be on the guide cable (24) but should be facing the guide cable (24). Switch on the main switch (7) (ON) (Fig. 8).
Press the “„STOP“” button (3) and open the control panel cover (13).
Press the lock button (62), unlock the robot lawn mower using the PIN, and conﬁ rm your entry with the “OK“ button (63) (see the section “Lock mechanism / PIN”).
Press the “HOME” button (61).
Then close the control panel cover (13).
Now the robot lawn mower will search for the guide cable (24) in order to ﬁnd the charging station (19). First it will travel forwards until it arrives at the guide cable (24). Depending on the situation the robot lawn mower might stop brieﬂ y beforehand in order to
re-orientate. Then the robot lawn mower will follow the guide cable (24) counterclockwise. Make sure there are no objects lying on the guide cable (24).
The battery of the robot lawn mower will now be fully charged. If any problems occur with docking, you might need to adjust the orientation of the charging station (19) until docking works without any problems.
To stop the robot lawn mower at any time, press the red „STOP“ button (3). When you press the „STOP“ button (3), the robot lawn mower will come to a stop and wait for further instructions.
Check in addition those places which lie far away from the search loop and those areas which are connected by bottlenecks. Repeat the process as described above and use the “HOME” button (61) to send the robot lawn mower back to the charging station (19).

5.10.2 Checking the mowing area (Fig. 6b)
To check the boundaries of the mowing area, walk along the lawn boundary and check if the mowing area is completely surrounded by boundaries or obstacles. Repeat this with all areas which are to be excluded, e.g. ﬂ ower beds, pools or ponds, and check whether these areas are clearly separated from the mowing area at all points. It is recommended to examine critical points which you doubt that the robot lawn mower will recognize. For this purpose place the robot lawn mower a distance of 1 m away from the point you want to check. The robot lawn mower needs to be facing the point you want checked. Areas protected by a magnetic tape (27) must also be checked. Then start the unlocked robot lawn mower with the help of the “START A/B” button (64). First the robot lawn mower will travel forwards and should then recognize the lawn boundary or the obstacle. You can interrupt the process at any time with the help of the „STOP“ button (3). Repeat this process at all points where you feel unsure.

5.10.3 Checking the position of the charging station (Fig. 6c)
Check the position of the charging station (19) by positioning the robot lawn mower at various points of of the lawn after calibration is completed and have the mower search for the charging station (19). First unlock the robot lawn mower, then press the “HOME” button (61) and close the control panel cover (13).
You can interrupt the process at any time with the help of the „STOP“ button (3). If necessary adapt the area, the laying of the guide cable (24) and the position of the charging station (19).

5.11 Securing the charging station
Once the robot lawn mower is working properly and a suitable position for the charging station (19) has been found, the charging station (19) must be ﬁ xed in place using the fastening screws(21). Use the hexagon key (22) to secure the fastening screws (21) fully in the ground (Fig. 7).

5.12 Battery charge level indicator
Press the button for the battery charge level indicator.
The battery charge level indicator indicates the charge state of the battery by means of 3 LEDs (Fig. 12b).
All 3 LEDs are lit:
The battery is fully charged.
2 or 1 LED(s) are lit:
The battery has an adequate remaining charge.
1 LED ﬂ ashes:
The battery is empty, recharge the battery.
All LEDs blink:
The battery temperature is too low. Remove the battery from the equipment, keep it at room temperature for one day. If the fault reoccurs, this means that the battery has undergone exhaustive discharge and is defective.
Remove the battery from the tool. Never use or charge a defective battery.
Important!
When using a multi-Ah pack (e.g. 4-6Ah), always set the higher capacity. Thanks to the gentle charging and discharging of the robot lawn mower there is no need to use the lower capacity in order to extend the working life.
5.13 Charging the battery with the charger
In normal operation the battery (A) of the robot lawn mower is charged via the charging station (19). For independent use of the battery (A) from the Power-X-Change series it can also be charged in the external Power-X-Charger. Important! –
Depending on the model of your robot lawn mower, it might not come complete with the battery charger (B).

Check that your mains voltage is the same as that marked on the rating plate. Insert the power plug of the charger (B) into the socket outlet. The green LED will begin to blink.
Insert the battery (A) into the battery charger (B) (Fig. 12a).
In the section entitled „Charger indicator“ you will ﬁ nd a table with an explanation of the LED display on the charger.

The battery can become a little warm during the charging. This is normal.
If the battery pack fails to charge, check:

Is there voltage at the power socket?
Is there good contact at the charging contacts?

If the battery pack still fails to charge, please send

the charger
and the battery pack to our customer service center.

To ensure that items are properly packaged and delivered when you send them to us, please contact our customer service or the point of sale at which the equipment was purchased.

6.5 Settings of the robot lawn mower
Setting the mowing time
The robot lawn mower is equipped with a camera unit (15) which can work only in daylight. As soon as twilight sets in, the camera unit (15) of the robot lawn mower will no longer be able to distinguish reliably between the lawn and the lawn’s boundaries. Consequently the robot lawn mower will return automatically to the charging station (19) at the onset of twilight. In such a case the set running time might not be reached.
This also applies when the set start time occurs during twilight or in darkness. Then the robot lawn mower will initially leave the charging station (19), only to return immediately along the guide cable (24) to the charging station (19). This results in the robot lawn mower not working on this day

Unlock the control panel (2).
Select the desired mowing time by pressing the corresponding button for setting the mowing time (60):
2.1 If you press the corresponding button (60) brieﬂ y, the robot lawn mower will mow each day. This will be indicated by the selected time LED lighting up permanently.
2.2 If you press the corresponding button (60) and keep it pressed for longer (6 seconds), the robot lawn mower will mow every second day. This will be indicated accordingly by the selected time LEDs ﬂ ashing.
This will be indicated accordingly by the time LEDs (50).
To conﬁ rm the setting, press the “OK” button (63).

The original duration of the set mowing window will be changed accordingly. The then applicable start time will remain unchanged but the duration will be altered to the indicated number of hours.
It is recommended to base the mowing time setting on 8 hours per day for 400 m² as a guideline.
The selected working time must be adapted to take account of the garden’s size and complexity.

Resetting the daily start time
To reset the daily start time, press the “OK” button (63) and the “6H” button (60) simultaneously and hold for 3 seconds. A successful reset will be conﬁ rmed with 5 beeps.
Then restart the robot lawn mower with the button “START A/B” (64).
The time at which the change was made is now the daily start time.
The number of hours shown is the daily work time.

Starting procedure

Unlock the control panel (2).
You can use the button “START A/B” (64) to select the area in which the lawn mower is to work. More details of the two areas can be found in the section “Before using for the ﬁ rst time” under “Mowing area”.
2.1 If you press the button “START A/B” (64) briefly, the robot lawn mower will mow in the main area (A). In this case the status LED (52) will light up green permanently.
2.2 If you press the button “START A/B” (64) and keep it pressed for longer, the robot lawn mower will mow in the secondary area (B).
The status LED (52) will then ﬂash green.
Close the control panel cover (13).

The robot lawn mower will now operate in accordance with the mowing time setting.
The battery charge level is monitored during the work time and displayed via the battery LED (55).
Whenever the battery charge level drops to 30%, the robot lawn mower will automatically return to the charging station (19).

Note: A reference value of the quality value is needed to operate the robot lawn mower. This reference value is determined as described in the section “Garden boundaries – Boundary quality value”, which is why the robot lawn mower begins initially with its mower unit switched oﬀ . If the value was determined already, the robot lawn mower will begin with the starting procedure in accordance with the selected mowing time setting.

Canceling the mowing operation

To bring the robot lawn mower to an immediate stop, press the „STOP“ button (3).
Open the control panel cover (13) fully.
Unlock the control panel (2).

Cleaning, maintenance and ordering spare parts

Danger!
The equipment must be disconnected from the power supply (pull out the power plug and switch oﬀ the equipment by the main switch (7) (OFF) (Fig. 8)) prior to performing any cleaning and maintenance work. Also take the battery (A) out of the robot lawn mower (Fig. 3b).
Caution! Wear working gloves!
7.1 Cleaning the tool

Keep all safety devices, air vents and the motor housing free of dirt and dust as far as possible. Wipe the equipment with a clean cloth or blow over it with compressed air at low pressure.
Do not clean the robot lawn mower with running water, particularly at high pressure.
Clean the equipment regularly with a damp cloth and some soft soap. Do not use cleaning agents or solvents; these might be aggressive to the plastic parts in the equipment. Ensure that no water can get into the interior of the equipment.
For best results, clean the robot lawn mower with a brush or rag.
Check the freedom of movement of the blades (10) and the blade plate (11).
Use cleaning product for metal or very fine abrasive paper to clean the charging contacts on the robot lawn mower (1) and the charging station (19). Clean them in order ensure efficient charging.

7.2 Maintenance

Check the lens of the camera unit (15) regularly for signs of dirt and clean if necessary.
The lens is likely to become dirty particularly when it rains. Do not use any aggressive cleaning agents or solvents.
Worn or damaged blades (10) and their fastening screws must always be replaced as a set.
Replace excessively worn or damaged parts immediately.
In order to ensure that you enjoy the equipment for many years to come, all screwed parts, as well as the wheels and axles, should be cleaned and lubricated.
Keeping your robot lawn mower in good condition not only ensures a long lifespan and high performance, but also enables the equipment to thoroughly cut your grass with minimal effort.
The blades (10) are subject to more wear and tear than any other component. Therefore, routinely check the condition of the blades (10) and make sure that they are tightly fastened. An excessively vibrating robot lawn mower can indicate that the blades (10) are damaged or have become deformed from striking an object. If the blades (10) are worn or damaged, they must be replaced immediately.
Check the appearance of the cut lawn at regular intervals. The grass will not be cleanly cut if the blades are not sharp. This can result in the surface of the lawn drying out easily and turning brown. It is important therefore to change the blades regularly in order to obtain a clean and straight cut.
Check the bottom of the robot lawn mower for dirt at regular intervals. Clean the robot lawn mower regularly. Remove heavy soiling immediately.
Heavy soiling of the robot lawn mower is possible in the first weeks of its use if you previously worked with a conventional lawn mower. In these first few weeks you should check the bottom of your robot lawn mower more often.
Shorten the lawn only in small steps in order to prevent heavy soiling.
There are no other parts inside the tool which require maintenance.

7.2.1 Replacing the blades
Use only original blades or correct performance and safety cannot be guaranteed.
The robot lawn mower is equipped with three blades (10) ﬁ tted to a blade plate (11).
These blades (10) have a service life of up to 3 months (if they do not strike any obstacles). Please replace all three blades (10) at the same time to ensure that there is no possibility of any impairment to the efﬁ ciency and balance of your equipment.
To change the blades (10), proceed as follows (Fig. 10 – Caution! – Wear work gloves:

Use a screwdriver to block the rotation of the blade plate (11). Do this by inserting the screwdriver through the holes in the blade plate (11) and the protective ridge.
Undo the fastening screws.
Remove the blades (10) and replace them with new ones. Always replace all three blades (10) as a set.
Then retighten the fastening screw. Check that the new blades (10) are able to rotate freely.

Perform a general inspection of the robot lawn mower at regular intervals and remove any deposits which have accumulated. At the start of each season, ensure that you check the condition of the blades (10). If repairs are necessary, please contact our customer
service center. Use only genuine spare parts.

7.2.2 Software update
If you want to update the software, copy the new software to an empty USB stick (format the USB stick ﬁ rst if necessary). Make sure that the battery is fully charged before you carry out the following steps.

With the robot lawn mower switched on, place it in the mowing area. The robot lawn mower must not be in the charging station (19) during the software update.
Connect a USB stick to the USB connection as shown (Fig. 11).
3.1 The robot lawn mower will now install the two ﬁ les one after the other. Alternatively the ﬁ les can be updated one at a time. In this case you must ﬁ rst switch oﬀ the robot lawn mower with the main switch (OFF).
3.2 System update (example of ﬁle name: CMK_3100.1.2.3.4.bin): Press the button “4H” for the mowing time setting (60) and simultaneously switch on the robot lawn mower with the main switch (7) (ON).
3.3 Camera update (example of ﬁ le name: Camera_1.2.3.4.bin): Press the button “10H” for the mowing time setting (60) and simultaneously switch on the robot lawn mower with the main switch (7) (ON).
The time LEDs (50) will ﬂ ash during the update process.
When ﬁ nished, the robot lawn mower will emit a continuous beep sound. If successful, all 4 time LEDs (50) will light up. If uncompleted, all 4 time LEDs (50) will go out and you will need to repeat the software update.
Pull out the USB stick and restart the robot lawn mower with the main switch (7).

7.2.3 Repairing the guide cable
First disconnect the charging station (19) from the power supply. If the guide cable (24) has been severed at any point, use the supplied cable connectors (25) to repair it. To do so, insert both ends of the severed guide cable (24) into the cable connector (25) and squeeze it with the help of a pair of pliers. Connect the power plug to the socket outlet.

FREELEXO CAM data protection notice

Einhell Germany AG is delighted that you are using the FREELEXO CAM robot lawn mower. The protection of personal data is an important concern for us. Below is a description of the data processed in general when the equipment is used.

Location of the charging station The location of the charging station is determined by means of GNSS positioning and saved locally on the robot lawn mower. This is required in order to navigate the mower back to the charging station when it has ﬁ nished its mowing work. When servicing is required, this information can be read out of the equipment physically via the logﬁ le.
Sunrise time and sunset time Sunrise time and sunset time are determined by means of GNSS positioning and saved locally on the robot lawn mower. This is necessary so that the equipment can be started only in a time interval when the camera unit is able to generate images with suﬃ cient brightness. When servicing is required, this information can be read out of the equipment physically via the logﬁ le.
Images produced by the camera unit Images generated by the camera unit are saved locally on the robot lawn mower. This is required by the system in order to constantly improve the robot lawn mower’s algorithm. On the mower you will ﬁ nd images which were generated during the last 15 minutes of mowing work. This data set is overwritten continuously. No images are generated when the mower is situated in the charging station or is looking for the charging station. When servicing is required, these images can be read out locally in order to understand any faults which have occurred. These images are then deleted.

Both the location-speciﬁ c data and the generated images can be deleted from the equipment by you yourself. In this case you must ﬁ rst switch oﬀ the robot lawn mower with the main switch. By simultaneously pressing the lock button (for deletion of GNSS data) or the “OK” button (for deletion of camera images) and switching on the robot lawn mower with the main switch you can delete the saved data. An acoustic signal will sound on the equipment to conﬁ rm deletion.
Detailed documentation on our data protection guidelines can be found on our homepage under “Data protection”.
