Functional Description

This robotic mower is an autonomous robot used for mowing lawns. It stays within an area delimited by a boundary wire, starts mowing according to a programmed cycle, and returns to its charging station when necessary. The three sharp blades ensure a clean cut of the grass without excessive damage, leaving very fine particles on the grass that act as natural fertilizer.

Technical Specifications

Mowing Information

The robotic mower has a cutting height adjustment from 20 to 60 mm. If the grass height exceeds 60 mm, reduce it to 60 mm or less before using the robotic mower. Otherwise, the load on the unit will be too heavy, and cutting efficiency will suffer. We recommend using a standard mower or trimmer of your choice. Once installation is complete, set the cutting height to your desired position. Always start with a high cutting position and gradually reduce it to the desired height. Before adjusting the cutting height, always press the STOP button (2) to interrupt mowing. Then, turn the large dial to adjust the cutting height. Note: Adjust the cutting height only when the robotic mower is switched off.

Assembly Guide

Installation Guide

This section describes the steps for installing the robotic mower. Please read this section in its entirety before starting the installation.

Introduction

We recommend drawing a plan of your garden, including all obstacles and how to protect them. This will help you identify a suitable location for the charging station and the boundary wire surrounding your lawn and shrubs, flower beds to protect, etc. You will also need some tools such as a hammer, cable cutter, pliers, or scissors.

Cutting Limits

The robotic mower is equipped with anti-collision sensors. These sensors detect any solid, fixed obstacle exceeding 10 cm in height, such as a wall, fence, or garden furniture. When an obstacle is detected, the robotic mower stops, reverses, and continues mowing in another direction. However, protecting obstacles by correctly surrounding them with boundary wire is the recommended long-term solution.

Trees

The Robomower considers trees as ordinary obstacles, but if tree roots are exposed and less than 100 mm high, you must exclude this area from the mowing surface using the boundary wire to protect the tree roots as well as the blades and rear wheels of the appliance.

Stones

We recommend removing all small stones (under 10 cm high) and those with rounded or inclined edges from the lawn. The robotic mower may attempt to climb over these stones instead of identifying them as obstacles. If the robotic mower gets stuck on a stone, the user will need to intervene to restart mowing. Contact with stones can damage the blades.

Slopes

The robotic mower can advance on slopes up to a maximum of 40%. The slope inclination must not exceed 40%.

Paths, Driveways, and Roads

If a raised driveway crosses your lawn, it is best to keep it outside the delimited mowing area. Please maintain a safety distance of 40 cm between the driveway and the boundary wire.

Irregular Lawn Areas

Irregular lawn areas can cause contact between the ground and the blades. We recommend leveling the lawn before using your robotic mower or excluding irregular areas using the boundary wire.

Flower Beds

Use the boundary wire to exclude any flower beds from the cutting area. Two options are available for placing the two sections of boundary wire between the flower bed and the external wire:

1. Maintain a distance of more than 10 cm between the parallel wire sections. This way, the robotic mower will identify the boundary wire as an ordinary obstacle. While mowing, it will 'bounce' off the wire as usual. To return to the charging station, the robotic mower will follow the boundary wire around the flower bed.
2. The second option is to maintain a distance of less than 5 mm between the parallel wire sections. Do not cross the wires (see below). This way, the robotic mower will not identify the wires and will cross them without slowing down. This option requires you to place an obstacle on the boundary wire surrounding the flower bed. Place the obstacle (a large stone or post) near position A indicated in the illustration below. The obstacle must be surrounded by a flat surface of approximately 1 m x 1 m without any unevenness. This obstacle will allow the tool to exit the loop.

Ponds and Pools

Although the robotic mower is protected against rain and splashes, total submersion can severely damage the electronic components. Therefore, it is imperative to exclude any water bodies from the mowing area. For added safety, it is recommended to install a fence around the water body.

Do's and Don'ts

Do not install the boundary wire directly under an ordinary electrical cable and parallel to it. The electrical field of the power cable can affect the boundary wire signal. Never cross two ends of boundary wires! Their radio signal will be altered, and the robotic mower's behavior will be unpredictable. Never cross the wires!

If you have created a delimited passage within the work area, this passage must be at least 2 m wide and a maximum of 8 m long. If a passage is too narrow or too long, the robotic mower may not be able to traverse it from end to end.

Defining the Robotic Mower's Work Area

You now understand the basic principles of the robotic mower's operation. The next step is to define the work area with the boundary wire according to your garden plan. This is a crucial installation step, so ensure you install the wire correctly. Starting from the charging station, the boundary wire must form a continuous loop without breaks or crossings. Connect the other end of the wire to the second terminal on the charging station to close the circuit. If necessary, use the supplied ruler to check the required safety distance of 40 cm. First, identify the best location for your charging station. Keep in mind that it must be permanently connected to a power outlet. Therefore, consider a location near an electrical outlet.

Fixing the Boundary Wire to the Ground

It is strongly recommended to mow the lawn to a maximum height of 60 mm before installing the boundary wire. Burying it is entirely optional. However, the closer the boundary wire is installed to the ground, the less you will trip over it or damage it while mowing. The wire will be quickly covered by grass. As the voltage is only 32 V, there is no risk of electric shock. Unpack the boundary wire (18) and locate the free end. Mark the boundary wire's location by inserting the stakes (15). Use the supplied ruler (16) to check the required 40 cm distance between the wire and obstacles. The recommended distance between two stakes is approximately 80 cm in a straight line and less on tight curves. Note that the hook and slot for the wire must always face outwards from the delimited area. When planting stakes for the first time, do not push them completely into the ground. Use a light hammer to push them in a bit further. Also, place each stake (15) at an appropriate distance (40 cm) from lawn edges and obstacles. Use the supplied ruler (16) for this purpose.

The stakes should be inserted into the grass with the slot for the boundary wire facing outwards as shown.

Once all stakes are in place, unroll the boundary wire. Start from the charging station. Insert the wire into each hook and slot of the stakes. Do not overtighten the boundary wire to avoid damaging it. Be careful not to twist it, tie knots, etc. When cutting the wire, it is advisable to allow at least 1 m extra for any adjustments.

Note: The stakes are not designed to fix the boundary wire on hard surfaces, for example, to run the boundary wire across a driveway. If necessary, use appropriate screws and anchors. Ensure you use insulating washers to protect the wire's insulation sheath.

Use only the supplied waterproof boundary wire connectors (17) to connect two sections of boundary wire. See the illustrations below for required distances.

Avoid right angles when fixing the boundary wire around a corner. Instead, soften the angle with two 45° angles.

If the supplied boundary wire is too short for your garden, you can purchase additional rolls from our supplier. The total length of the wire must not exceed 300 m.

Preparing the Boundary Wire for the Charging Station

Use wire strippers to remove 10-15 mm of insulation from each end. Twist the wires together tightly.

Connecting the Charging Station to the Boundary Wire

Place the charging station at the end of the boundary wire so that the wire passes under the charging station along its length and in the middle. Connect this end to the left (black) connector labeled 'F' (Forward). Connect the other end to the right (red) connector labeled 'B' (Back).

IMPORTANT INFORMATION: Verify that the charging station connections match the diagram below. Even if the blue indicator light is on, incorrectly connected terminals will prevent the tool from functioning.

Connecting the Charging Station to the Boundary Wire

After connecting the 'F' and 'B' terminals to the charging station, the boundary wire can be secured to the ground using the stakes. Before fixing the charging station, please re-verify that the conditions mentioned above are met:

• Level surface near a power source
• 2 m of straight boundary wire in front of the station
• Inclination less than 5%
• Excess boundary wire neatly stored flat under the charging station, outside the delimited area.

Once the charging station is fixed, connect the power cord (14) to the charging station. Then, connect the power cord to the electrical outlet. After a short automatic test, a blue LED should light up on the charging station. If no LED lights up, recheck the electrical outlet and the power cord. If any other indicator light besides the blue LED lights up, consult the 'Troubleshooting' section.

Turning On and Testing the Installation

Once the blue LED indicates everything is in order, test the robotic mower's operation. Regularly check the LED to ensure the boundary wire connection has not been affected. Then, place the robotic mower in the work area, a few meters from the charging station. Set the main power button (11) to ON. The robotic mower will turn on and perform an automatic test, but will not start mowing yet.

Press the large STOP button (2) to open the top cover and access the controls. Activate the button with the icon (located on the left of the panel) and close the cover.

Once the cover is closed, the robotic mower should start moving. It will automatically head towards the charging station by detecting and following the boundary wire counter-clockwise. If the robotic mower cannot park correctly on the station, move the station to a more suitable location. Once parked, the charging symbol will start flashing, indicating the battery is charging correctly. After the initial installation, the robotic mower will remain on the charging station until the battery is fully charged. If the robotic mower parks and charges correctly, it means the chosen location for the charging station is adequate. You can now fix it in place by fully inserting the stakes into the ground. Be careful not to damage or twist the excess wire stored under the charging station.

Operation

Control Panel

Once the robotic mower is fully charged, it is ready to be programmed. Although the default factory settings are suitable for most users, it may be useful to familiarize yourself with the available options. To start programming, press the large STOP button (2) to open the top cover and access the controls.

The control panel has five functional zones:

Note: If you have forgotten your PIN code, please set a new code as indicated above.

LED Indicator Lights

Lift Alert

A red LED lit above this symbol indicates that the lift sensor has been triggered. Note: Vibrations or collisions can also trigger the lift sensor. If this sensor is triggered for less than 1 second, the robotic mower will immediately resume its scheduled work. If triggered for more than 1 second but less than 8 seconds, the robotic mower will resume work after a short pause. If the lift alert lasts for more than 8 seconds, the robotic mower's anti-theft system will be activated. The unit will lock automatically, and an alarm will sound.

Boundary Wire Signal

The boundary wire emits an electromagnetic signal. The robotic mower uses this signal to determine if it is within the mowing area. The red LED above this symbol flashes when the unit is not receiving the 'within the delimited area' signal. In this case, the robotic mower immediately stops mowing.

Low Battery Symbol

This LED lights up when the battery is low. In this case, the robotic mower immediately returns to its charging station.

Charging

This LED flashes during battery charging. A continuously lit LED indicates that the battery is fully charged. During charging, the boundary signal receiver is turned off to save energy. Once the battery is fully charged, the 'boundary signal' LED may then light up.

Setting Work Duration

The buttons above allow you to select the daily operating hours for the robotic mower. Please consult the table below for the recommended daily work duration based on the work area size.

The current work duration is indicated by the illuminated button. A flashing button means the tool has already completed the planned work hours for the day. Note: The average work duration with a fully charged battery is less than the minimum adjustable work duration of 4 hours. When the robotic mower returns to its charging station, the clock does not stop. Charging time is counted towards the work duration.

Once the work duration is selected, the corresponding LED will light up. A flashing LED means the work duration has been completed.

Signal Setting

To avoid interference with another robotic mower, two different boundary wire signals are available. Ensure you use the same signal (S1 or S2) for both the charging station and the robotic mower. Use the buttons located at the rear of the charging station to select signal S1 or S2.

RETURN TO STATION and START Button

Press the START button and close the top cover. The robotic mower will begin mowing. Once the programmed work duration is completed, the unit will return to the charging station.

Important Note: The robotic mower will resume work the following day at the time the START button was initially activated. Example: You start the robotic mower on a Monday at 3:30 PM for a 4-hour work duration. The unit will work that Monday until 7:30 PM and then return to its station. On Tuesday at 3:30 PM, the robotic mower will automatically resume work for 4 hours. This will continue daily until the programming is interrupted by the user.

RETURN TO STATION

If you press the RETURN TO STATION button and close the cover, the robotic mower will automatically return to its station for a full recharge. This does not interrupt the current programming. If the work duration is not completed after charging, the unit will resume mowing. It will also resume work the following day.

STOP

To interrupt the automatic work programming, press the STOP button to open the top cover, then close it without pressing any control buttons. The robotic mower will emit four beeps to confirm the interruption. It will not resume work without a subsequent user command.

Cutting Edges

The mowing cycle will start each day by mowing the lawn edges. The robotic mower mows by following the boundary wire clockwise. This function is only activated when the robotic mower leaves the charging station.

Cleaning/Maintenance

Any action not specified in these instructions must be performed by one of our authorized repair agencies. Use only original parts.

Ensure the main power button (11) is set to OFF. Wear protective gloves. Tilt the robotic mower onto its side to expose the underside of the appliance. Clean the blade holder and frame using a soft brush or a damp cloth. Rotate the blade holder to ensure it turns freely and check that the blades rotate without being obstructed by grass.

Cleaning Contact and Charging Terminals

Using steel wool, a metal sponge, or fine-grit sandpaper, clean the contact and charging terminals on your robotic mower and the charging station. Remove debris, leaves, and grass around the contact and charging terminals to ensure efficient charging.

Returning or Replacing Blades

WARNING! Ensure the robotic mower is completely turned off before any cleaning, adjustment, or blade replacement. Always wear protective gloves.

WARNING! For maximum cutting efficiency and safety, always use blades and blade fastening parts recommended for replacement.

Your robotic mower is equipped with three blades attached to the blade holder. Unless damaged by hard obstacles, these blades can withstand up to five months of daily use. Weekly inspection of the blades and fixing screws is necessary. Please note that the blades are double-edged. Once the first side is dull, unscrew the fixing screw. Turn the blade over and re-fix it with the fixing screw. After tightening the fixing screw, check if the blade rotates freely around the screw.

A set of replacement blades is included with the robotic mower. For subsequent replacements, contact customer service. The spare part number for the blades is 846210. Use only original spare parts. For optimal performance and to prevent imbalance, always turn over or replace all three blades at the same time.
