To reduce the risk of serious or fatal injuries, we recommend persons with medical implants to consult their doctor and the manufacturer of the medical implant prior to using the equipment.

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 aff ects how eff ectively the robot lawn mower works later on.

How it works
The robot lawn mower chooses its direction on a random basis. The robot lawn mower works its way over every area which is enclosed within the perimeter wire (18), so that the entire garden gets mowed. Whenever the robot lawn mower detects a correctly installed perimeter wire (18), the robot lawn mower turns about and drives in a diff erent direction within the area. All zones that you wish to protect within the lawn area – e.g. garden ponds, trees, furniture or fl ower beds – must be cordoned off by the perimeter wire (18). The perimeter wire (18) must form a closed circuit. If the robot lawn mower bumps into an obstacle within the mowing area, it reverses and then continues mowing in a diff erent direction (Fig. 3).

Sensors
The robot lawn mower is equipped with a number of safety sensors.

• Lifting sensor:
  If the robot lawn mower is lifted by more than 30° from the ground at the back, the robot lawn mower and the rotation of the blades (10) are 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) are stopped immediately.

• Obstruction 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 will be stopped immediately and the mower will reverse away from the obstacle.

• Rain sensor:
  The robot lawn mower is equipped with a rain sensor (5) to prevent the robot lawn mower from operating in the rain. The robot lawn mower returns to the charging station (19) when it detects rain and is completely recharged there. Once the rain sensor (5) is dry again, the robot lawn mower will stay in the charging station (19) for another two hours. 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.

Preparations
First, draw a sketch of your lawn. Include obstacles in your sketch and draw up a plan for how you intend to protect them. This will make it easier to fi nd a good position for the charging station (19) and to lay the perimeter wire (18) around bushes, fl ower beds, etc (Fig. 4)..

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 damage the robot lawn mower itself. Have the following tools ready: A hammer, tongs, a wire stripper and a spirit level (optional).

Fitting the battery
A battery (A) from the Power-X-Change series is needed to operate the robot mower. Important: Depending on the model of your robot lawn mower, it might not come complete with the battery (A).

Open the battery compartment cover (9) by pulling the snap fastener. Press the of the pushlock button of the rechargeable battery (A) and push the rechargeable battery (A) into the mount provided. Close the battery compartment cover (9) and make sure that it latches in place correctly (Fig. 10).

Open the battery cover (9) to remove the battery (A). Press the pushlock button of the battery (A) and pull out the battery.

Charging station
Position of the charging station
Determine the best position for the charging station fi rst (19). An outdoor socket outlet is required which supplies 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 at the level of the turf. Make sure that the area is fl at and dry. Select a position which is in the shade, because it is best if the rechargeable battery is charged up in a cool area (Fig. 5a).

Also note that the perimeter wire has to be laid in a straight line for least 2 m in front of the charging station (19). Curves immediately in front of the charging station (19) could cause problems when docking for charging.

Localization of the charging station
When the rechargeable battery is almost empty, the robot lawn mower returns to the charging station (19) by following the perimeter wire (18) in a counterclockwise direction until it reaches the charging station (19). Make sure, therefore, that the charging station (19) faces in the right direction when you position it (Fig. 5b)

Connecting the charging station to the power supply unit

1. 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.
2. Connect the power supply unit (13) directly to a socket outlet. Do not use the cable for any other use.
3. Do not use the power supply unit if it is damaged (13). In the event of any damage to cables or the power supply unit (13), contact an authorized professional immediately for replacement.
4. Do not charge up the robot lawn mower in a damp location. Do not charge up the robot lawn mower at temperatures above 40°C or below 5°C.
5. Keep the robot lawn mower and the power supply unit (13) away from water, sources of heat and chemicals. Keep the cable of the power supply unit (13) away from sharp edges in order to prevent damage.
6. Connect the power supply unit (13) to the charging station (19) (Fig. 5c).
   

To charge up the rechargeable battery for the robot lawn mower straight away while you are still doing the installation work, fi rst switch on the robot lawn mower with the main switch (7) and place the robot lawn mower in the charging station (19).

Information about charging
The robot lawn mower returns 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.

In these cases the robot lawn mower automatically runs along the perimeter wire (18) until it reaches the charging station (19).

When the robot lawn mower wants to return to the charging station (19), it will fi rst look for the perimeter wire (18) and then move along the perimeter wire (18) in counter-clockwise direction. The LED indicator (21) on the charging station (19) lights up red while charging of the rechargeable battery is in progress. When the LED indicator (21) on the charging station (19) turns to green, this indicates that the rechargeable battery is fully charged. Once it ha
been fully charged, the robot lawn mower resumes operation or remains in the charging station until the next work time window (19). If there is an obstacle on the perimeter wire (18) 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 perimeter wire (18). If the temperature of the rechargeable battery exceeds 45°C, charging will stop in order to prevent damage to the rechargeable battery. Charging resumes automatically once the temperature has dropped again. If the temperature of the controller of the robot lawn mower exceeds 75°C, the robot lawn mower will return to the charging station (19). Operation resumes in accordance with the settings once the temperature has dropped again.

If the rechargeable battery becomes empty before the robot lawn mower has returned to the charging station (19), it will not be possible for the robot lawn mower to start up again. Bring the robot lawn mower back to the charging station (19) and leave the main switch (7) switched on. The robotlawn mower will be charged up automatically.

Perimeter wire
IMPORTANT! Severed perimeter wires and consequential damages are not covered by the warranty!

Laying the perimeter wire
The perimeter wire (18) can be laid both on the ground and in the ground. The fastening pegs (14) can break when hammered in if the ground is hard or dry. Water the lawn before installing the perimeter wire if the ground is very dry.

• Installation on the ground
  Lay the perimeter wire (18) securely on the ground and fasten it with the supplied fastening pegs (14) if you do not intend to scarify or aerate the lawn any time later. You can still adjust the position of the perimeter wire again during the first few weeks of using the robot lawn mower. After a certain time, however, the perimeter wire will become overgrown with grass and no longer visible. Install the perimeter wire with a maximum distance of 1 m between fastening pegs (14). Reduce the distance between the fastening pegs on uneven areas of the lawn. Avoid situations in which the wire is not actually on the ground. Make sure that the perimeter wire cannot be severed by the robot lawn mower.

• Installation in the ground
  Bury the perimeter wire in the ground at a depth of up to 5 cm. This will prevent the perimeter wire (18) getting damaged during scarifying or aeration, for example.

Narrow points
If the lawn has a narrow point, your robot lawn mower will be able to operate there as long as the corridor has a width of at least 1.4 m (80 cm between the perimeter wires) and a maximum length of 8 m (Fig. 3)..

Distance to the garden perimeter
When the robot lawn mower approaches a perimeter wire (18), the perimeter wire is detected by the sensors in the front of the robot lawn mower. Before the robot lawn mower turns about, however, it runs over the perimeter wire (18) by up to your mowing area (Fig. 6a)

. 5.5.4 Laying the wire in corner  Avoid laying the perimeter wire (18) at a rightangle (90°) in corners. To make sure that the robot lawn mower does not run too far beyond the perimeter wire (18), lay the perimeter wire (18) as shown in Fig.6b.

Calculating the gradient of the lawn
The robot lawn mower can cope with gradients of up to 35%. You therefore need to avoid steeper gradients. The gradient can be determined on the basis of the height divided by the distance (Fig. 6c).

Example: a/b = 35 cm/100 cm = 35%

Installation of the perimeter wire on gradients
The robot lawn mower can slip on gradients, especially if the grass is wet, and run over the perimeter wire (18) as a result. It is therefore recommendable to pay attention to the following points ( Fig. 6d):

• In the area at the top of a slope, the perimeter wire (18) should not be installed on gradients over 35%. Make sure that a distance of 30 cm from obstacles and the edges of the lawn is maintained.
• In the area at the bottom of a slope, the perimeter wire (18) should not be installed on gradients over 17%. Make sure that a distance of 40 cm from obstacles and the edges of the lawn is maintained.

Driveways and paved paths

• Cordon off raised pathways, areas surfaced with gravel or containing bark mulch, lower lying beds or other similar areas. Lay the perimeter wire (18) at a distance of at least 30 cm away (Fig. 6e and 6g).
  
  
  

• Paths which are flush with the turf do not need to be cordoned off, because the robot lawn mower can simply run over them. You can also lay the perimeter wire (18) over paths ( Fig. 6f and 6g).

`Perimeter islands
To protect obstacles in the mowing area, create perimeter islands. This will enable collisions with delicate objects, garden ponds, trees, furniture, fl ower beds, etc., to be avoided (Fig. 6h and 6i).

• Roll out the perimeter wire (18) from the edges to the objects you want to protect.

• Secure the perimeter wire (18) with fastening pegs (14) in a clockwise direction around the object you want to protect.

• Completely enclose the perimeter islands and then run the perimeter wire (18) back to the point at which you left the edge of the lawn.

• Perimeter islands need to be at least 0.8 m apart. Alternatively, combine the objects to make them into a joint perimeter island (Fig. 6h).
  

• The perimeter wires (18) to and from the perimeter island should be laid parallel and very close to one another. – Caution! Perimeter wires (18) must not cross over! – You should therefore fasten both the parallel perimeter wires (18) to the ground together using the same fastening peg (14) (Fig. 6i).
  

• The robot lawn mower will run over the two parallel perimeter wires (18) in the mowing area, but the robot lawn mower will stop where single perimeter wires (18) are laid.

Obstacles

• Obstacles with a height over 10 cm (Fig. 6j)
  
  Solid obstacles which are over 10 cm in height, e.g. trees, walls, fences, garden furniture, etc., are detected by the collision sensors. If the robot lawn mower collides with an obstacle, it will stop, switch off the mower unit, reverse and turn so that it can continue mowing in the other direction. Soft, unstable and valuable obstacles need to be protected by a perimeter wire island.

• Stones and low obstacles
  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.

• Trees ( Fig. 6k) The robot lawn mower treats trees as obstacles. However, where any tree roots projectabove 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. Make sure that the minimum distance between the perimeter wire (18) and the obstacle is 30 cm.

Connecting the charging station
Finish laying the complete perimeter wire (18) before you connect it to the charging station. Keep an extra length of 1 m of perimeter wire (18) at each end so that you can make further adjustments at a later time. Using a wire stripper, remove a length of 10 to 15 mm of the insulation at the ends of the perimeter wire (18) for connecting to the charging station (19).
Pull out the power plug before you connect the perimeter wire (18) to the charging station (19). The perimeter wire (18) laid to the front end of the charging station (19) must be run to the back via the cable holders on the underside of the charging station (19). Pass the front perimeter wire (18) through the guides under the charging station and through the hole prepared in the connection area. Connect this wire to the “+” connection. Then connect the rear perimeter wire (18) to the “S1” connection (Fig. 7a).

Important! Perimeter wires (18) must not cross over!
Then connect the power supply. The LED indicator (21) on the charging station (19) should light up green and stay on permanently. If the LED does not light up, check the connections fi rst. If the LED lights up green but not permanently, read the “Indicators on the charging station and troubleshooting” table at the end of these operating  instructions.

Switching on and checking the installation
As soon as the LED indicator (21) on the charging station (19) lights up green, the mowing area is ready for the robot lawn mower. Please check fi rst that all the fastening pegs (14) on the perimeter wire (18) have been fully tapped in. Place the robot lawn mower about 3 m to the rear of the charging station (19) in front of the perimeter wire (18). The robot lawn mower needs to be facing the perimeter wire (18) at an angle of 90° (Fig. 7b).

Switch on the main switch (7) (ON) (Fig. 8).

Press the POWER button (60) on the control panel (2) for two seconds. Unlock the robot lawn mower using the PIN and confi rm the entry with the “OK” button (61) (see chapter “Locking mechanism / PIN”). Press the “HOME / 3” button (64) and then press the “OK” button again (61). The robot lawn mower will now follow the perimeter wire (18) in a counterclockwise direction. Observe the robot lawn mower during the complete trip along the perimeter wire (18) until it is back in the charging station (19). If the robot lawn mower has any problems at any points, correct the perimeter wire (18) if necessary and repeat the operation. The rechargeable battery of the robot lawn mower will now be fully charged. If any problems occur with docking, you may need to reposition the charging station (19) sideways 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.

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 (15). Use the hexagon key (22) to secure the fastening screws (15) fully in the ground (Fig. 7c).

Battery capacity indicator
Press the button for the battery capacity indicator. The battery capacity indicator shows the charge status of the battery using 3 LEDs (Fig. 13b).

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 rechargeable battery has undergone exhaustive discharge and is defective. Remove the battery from the equipment. 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.

Charging the rechargeable 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 (Fig. 13a/Item B).

1. Check that your mains voltage is the same as that marked on the rating plate of the battery charger. Insert the power plug of the charger (B) into the socket outlet. The green LED will then begin to fl ash.

2. Insert the rechargeable battery (A) into the battery charger (B) (Fig. 13a).
   

3. In the section entitled „Charger indicator“ you will fi nd a table with an explanation of the LED indicator on the charger.

The rechargeable battery can become a little warm during the charging. This is normal.

If the battery pack fails to charge, check:

• whether there is voltage at the socket outlet
• whether there is good contact at the charging contacts

If the battery pack still fails to charge, 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.

When shipping or disposing of batteries and cordless tools, always ensure that they are packed individually in plastic bags to prevent short circuits and fires.

To ensure that the battery pack provides long service, you should take care to recharge it promptly. You must recharge the battery pack when you notice that the performance of the device drops. Never allow the battery pack to become fully discharged. This will cause it to develop a defect.

Operation

Control of the robot lawn mower using the app
All settings that you can make using the control panel can also be made using the app. To do so, fi rst download the Einhell app for robot lawn mowers to your smart phone. The Einhell app is available via the following link and QR code:

iOS: http://qr.einhell.com/12e103ce

Android: http://qr.einhell.com/176c0443

Use a Bluetooth connection to connect the robot lawn mower with your smart phone and follow the steps shown there. You can also use the app to use the following additional functions of the robot lawn mower:

• Mowing time settings:
  The app gives you additional options for mowing time settings, e.g. a daily individual mowing time setting.

• Rain sensor
  The rain sensor (5) can be switched on and off in the app. The default factory setting for the sensor is “On”.

• Multi-starting point
  Where gardens have lots of angles, the robot lawn mower may have problems reaching every part of the lawn and mowing it completely. In this case you can select several starting points on the perimeter wire (18). This will enable the robot lawn mower to get to even those parts of your garden that are diffi cult to reach. The robot lawn mower will run the selected distance along the perimeter wire (18) and then start mowing in this part of the garden (Fig. 9c). The charging station (19) is automatically defi ned as starting point 1. The two other starting points can be selected as you wish.

• 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.

Maintenance

• 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 equip ment 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 your robot lawn mower regularly. Remove heavy soiling immediately.
• Heavy soiling of the robot lawn mower is possible in the first weeks of using it for the first time after a conventional law mower had previously been used. 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 equipment which require maintenance.

Replacing the blades
Only replace the blades with genuine blades, as this will ensure top performance and safety. 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. 12) – Caution! – Wear work gloves:

1. Undo the fastening screws
2. Remove the blades (10) and replace them with new ones. Always replace all three blades (10) as a set.
3. 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 may 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.
