Before using your ROBOMOW RX20U, it is important to follow these safety precautions:

Before you begin:

1. Read the Safety Manual carefully to become familiar with the mower’s controls and proper use.

2. Never allow children, persons with reduced physical, sensory or mental capabilities, or people unfamiliar with these instructions to use the machine.

3. You are responsible for accidents or harm to other people or their property.

4. It is your responsibility to inform your neighbors about the risks and that it is forbidden to enter your lawn while the mower is operating.

5. If your lawn is open to the street or neighbors, you must be present during the mower’s operation to prevent others from accessing your lawn. Alternatively, you must protect or fence your lawn.

Preparations:

1. Ensure the correct installation of the Perimeter Wire.

2. Periodically inspect the area where the mower is used and remove all stones, sticks, cones, wires, and other foreign objects.

3. Periodically visually inspect the blade to ensure it is not worn or damaged. Replace a worn or damaged blade (Part No. MRK9100A/MRK9100W). Switch the mower off when inspecting or replacing the blade.

Operation:

Do not leave the mower to operate unattended if you know that there are pets, children, or people in the vicinity. Never mow while people (especially children) or pets are nearby.

1. Do not operate the mower if any safety feature or part is damaged, worn, or inoperable.

2. Keep hands and feet away from the cutting blade and other moving parts.

3. Always switch the mower off before lifting it or planning to operate any adjustments.

4. Never pick up or carry the mower while the motors are running.

5. Do not touch the blade before it has completely stopped rotating.

6. Do not use the mower for any purpose other than cutting lawn.

7. Keep all guards, shields, safety devices, and sensors in place. Repair or replace damaged parts, including decals.

8. Set the weekly program at times when there are no people on the grass.

9. Do not connect a damaged power cord to the supply, or touch a damaged cord before it is disconnected from the supply as it can lead to contact with live parts.

10. Keep the extension power cord away from the blade to prevent the mower from damaging it.

11. If the power cord becomes damaged or entangled during use, detach it from the mains by pulling the plug from the socket.

12. In the event of an accident or breakdown while the mower is operating, immediately press the red STOP button.

The warning decals on your ROBOMOW RX20U have the following meanings:

1. This is a dangerous power tool. Exercise care when operating and follow all safety instructions and warnings.

2. Read the Safety Manual carefully before operating your mower.

3. Be careful of thrown objects during operation.

4. Keep a safe distance from the mower while it is operating. Keep people, especially children, pets, and bystanders away from the area where the mower is operating.

5. CAUTION: Do not touch the rotating blade. Keep hands and feet away and do not lift the mower from the ground.

6. Remove the disabling device before working on or lifting the mower.

7. Do not ride the mower.

Your ROBOMOW RX20U is equipped with numerous built-in safety features:

A. Child Lock: Prevents unintended operation by an accidental press of one of the buttons. Only pressing two buttons in the right order will initiate the operation. It is required to activate the Child Lock feature if children under age 6 may come in contact with the mower.

B. Disabling Device: Prevents anyone from operating the mower when it is removed. It is highly recommended to remove the Disabling Device to prevent operation of the mower by children or people who are unfamiliar with the mower or are not allowed to use it.

C. Lift Sensor: If the mower is raised from the ground during the blade’s operation, the blade will stop rotating immediately.

D. Tilt Sensor: If the mower is tilted up towards a vertical position, the blade will stop immediately.

E. Obstruction Sensor: The mower detects interfering obstacles in its way during operation. When the mower collides with an obstacle, it will stop the rotation of the blade immediately, stop movement in that direction, and reverse itself away from the obstacle.

F. Emergency Stop Button: Pressing the STOP button at any time during operation will stop the mower and the blade immediately.

G. GO/ON-OFF button: Allows you to completely power off your mower. Switching the mower off will prevent it from any operation. It is required to switch the mower off before lifting it and before any maintenance operation.

H. Base Station and Perimeter Wire: Your mower cannot operate without a Perimeter Wire installed and activated through the Base Station. In the event the Perimeter Wire signal is turned off, the mower will stop operating.

Within the working area:

1. Press the STOP button to stop the mower.

2. Switch the mower off, and carry it by its carrying handle.

Over long distances:

When transporting your mower over long distances, make sure it is switched off. It is recommended to keep the original packaging for shipping purposes.

1. Always switch the mower off and remove the Disabling Device before clearing blockage, checking, cleaning, or working on it, or after striking a foreign object to inspect the machine for damage. Never attempt to service or adjust the mower while it is in operation.

2. In case of abnormal vibrations, stop the mower, switch it off and check for any damage to the blade. Replace a worn or damaged blade (Part No. MRK9100A/MRK9100W) to preserve balance. If the vibration continues, call for service.

3. Use heavy gloves when inspecting or servicing the blade.

4. Do not perform maintenance barefoot or wearing open sandals. Always wear suitable work shoes and long trousers.

5. Replace worn or damaged parts for your safety.

6. Use only original equipment and accessories. It is not permitted to modify the original design of the mower. All modifications are made at your own risk.

7. Ensure that only replacement cutting means of the right type (Part No. MRK9100A/MRK9100W) are used.

8. Maintenance, servicing, and cleaning of the mower should be according to manufacturer’s instructions.

9. Keep all nuts, bolts, and screws tight to be sure the machine is in safe working condition.

The Battery Pack contains electrolytes. In case of an electrolyte leakage from the Battery Pack on your ROBOMOW RX20U, the following actions should be taken:

Skin contact: Wash the contact areas off immediately with water and soap.

Eye contact: Flush the eyes with plenty of clean water for at least 15 minutes immediately, without rubbing.

Medical: Get medical assistance.

Also, ensure that the battery is charged using the correct charger recommended by the manufacturer. Incorrect use may result in electric shock, overheating, or leakage of corrosive liquid from the battery.

When there is a risk of a lightning storm, disconnect the Perimeter Wire from the Base Station and the Power Supply 230 V/120 V plug from the power outlet.

1. The ROBOMOW RX20U and its accessories should be collected separately at the end of their life to prevent waste electrical and electronic equipment from ending up in landfill sites, and to protect and improve the quality of the environment.

2. Do not dispose of the mower or any other of its parts (including the Power Supply and Base Station) as unsorted municipal waste; they should be collected separately.

3. Ask your local distributor/dealer about return and collection systems availability.

4. Do not dispose of the battery pack in a fire, and do not place used batteries in your household trash.

5. The battery must be collected, recycled, or disposed of in an environmentally sound manner.

The installation process for your ROBOMOW RX20U involves five main steps:

1. Get started: Choose the Base Station location.

2. Lay the wire: Wire your lawn.

3. Set base: Install the Base Station.

4. Power up: Connect everything.

5. GO!: Your mower is ready.

The following items are included with your ROBOMOW RX20U:

The product: Your new Robotic Mower

Base Station: This is where the mower recharges

Wire Pegs: For securing the wire to the ground

Perimeter Wire with a plot connector: Marks the working area for your mower

Base Station Head: Generates Perimeter Wire signal

Power Supply: With 10 m / 33 ft extension cable

Base Station Stakes (x4): For affixing the Base Station to the ground

Wire Connectors: For splicing the Perimeter Wire in case of a cut

Plot Connectors: For connecting the Perimeter Wire to the Base Station

User Guide: Instructions for your mower

RoboRuler: For measuring the Perimeter Wire’s distance from the lawn’s edge

RoboTool: For blades replacement and servicing. Keep this tool for future use.

Follow these simple guidelines to find a proper location for your ROBOMOW RX20U Base Station:

Rule #1: Up to 10 meters / 33 feet away from a power outlet.

Rule #2: A minimum of 1 meter / 3.3 feet of straight wire before, after, and aside the base to allow smooth docking.

Rule #3: The location must be even and flat (up to +/-5% slope).

Rule #4: A minimum of 1 meter / 3.3 feet from a sprinkler head to avoid hitting the mower directly and damaging its internal components.

Also, watch the proper direction of the Base Station relative to the lawn’s edge. The Base Station will be installed after the Perimeter Wire is in place.

Use the included RoboRuler to determine the correct distance between the Perimeter Wire and the lawn’s edge for your ROBOMOW RX20U:

If the edge is relatively flat, lay the wire at RoboRuler distance II from it.

If the edge is a drop or if the ground is sandy/soft, use distance III of the RoboRuler.

When the edge is a wall or a bush, use distance IV of the RoboRuler.

Keep a minimum of 1.2 m (4 ft) if the edge of the lawn borders water.

Slopes along the edge: To ensure your ROBOMOW RX20U doesn’t slip off the lawn, especially when the grass is wet, the Perimeter Wire must exclude a slope along the edge of your lawn with an incline of over 10% (10 cm rise per 1 m or 4 in rise per 3 ft).

Slopes within the lawn: Your mower can mow areas within the lawn with a slope of up to 15% (15 cm rise per 1 m or 0.5 ft rise per 3 ft).

1. Start unwinding the wire counter-clockwise around the lawn, starting at the Base Station’s location.

2. Lay the Perimeter Wire loosely along the perimeter as you walk along the lawn’s edge.

3. The Perimeter Wire is secured to the ground by the pegs supplied with the product.

4. Pull the wire tight while hammering the pegs to their final depth in the ground. Take care not to damage irrigation pipes.

5. Place the pegs every few tens of centimeters.

6. Add pegs where necessary to keep the wire tight to the ground to avoid damaging it by the mower.

Hard obstacles: Obstacles that are vertical, rigid, and higher than 15 cm (6 in), such as trees or telephone poles, do not need to be protected by the Perimeter Wire. The mower will bump into them and turn away.

Soft obstacles: Objects such as flower beds, ponds, or small trees must be protected by setting Perimeter Islands. Also, tree roots that stick out more than 2 cm above the ground should be protected by a perimeter island.

When creating a perimeter island, set the Perimeter Wire CLOCKWISE around the obstacle. Otherwise, the mower will drive into the Perimeter Island or won’t be able to mow the area around it properly.

Set Base:

1. Place the Base Station in its planned location.

2. Properly align the center of the Base Station with the Perimeter Wire.

3. Fix the base to the ground with the 4 supplied metal stakes. Be careful not to damage irrigation pipes when hammering down the stakes.

Power Up:

1. Connect the wire tail marked ‘A’ to the ‘A’ terminal and the other tail to the ‘B’ terminal of the Base Station head.

2. Connect the power supply connector to the Base Station head as well.

3. Note the markings for placing the Base Station Head.

4. Place the head on the Base Station and align it with the markings.

5. Slide the head all the way through. Pay attention to the sliders and a dedicated slot for threading the wires.

6. Plug in the power supply into a socket. Take the power cord out of the mowing area and secure it firmly to the ground so that it does not become a tripping hazard.

If you need to remove the base station head, you can do so by lifting the lever (A) and pushing it towards the inside of the base.

1. Place your ROBOMOW RX20U in the center of your lawn.

2. Press the GO button for 2 seconds to switch it on.

3. Now press the STOP / Home button once to send the mower to the Base Station.

The mower will start driving towards the edge of the lawn to locate the Perimeter Wire. Once on the wire, the mower will follow it to reach the Base Station and park there for charging.

With child protection enabled: A special combination is required. Hold down the STOP button and press the GO button once to unlock the child protection for 30 seconds. The Lock indication will temporarily switch off. Now you can start a mowing operation as described above. As soon as the mowing operation is started, the child protection will automatically relock itself.

Stopping an operation: To stop any current operation, press the STOP / Home button.

Sending the mower to its base: To send the mower to its base, simply press the STOP / Home button when the mower is inside the lawn. If child protection is enabled, you must first temporarily unlock it.

Automatic charging: Once a mowing operation is finished, your mower automatically returns to its base station for charging to be ready for the next operation.

The recommended weekly mowing times for your ROBOMOW RX20U in peak season are as follows:

(*) Check the recommended lawn size in your mower’s specifications. For the best look of your lawn, we recommend spreading the mowing times evenly among as many days in a week as possible.

Always switch the mower off before lifting it. Wear heavy work gloves when working with or around the blade. Perform the following checks once a month:

1. Inspect the underside of the mower. Clean if necessary. Carefully scrape the collected grass debris (using a small stick or similar object) from under the mowing deck.

2. Check the Perimeter Wire and add pegs where it is loose and not tight to the ground. In case of seasonal changes in the lawn, make sure to adjust the wire accordingly.

3. Inspect the Base Station, clean it from mud and debris to allow proper docking.

IMPORTANT: NEVER use high-pressure water to clean the mower. Liquids can damage components. Use only an air blower or wet cloth to wipe the surface clean.

1. Power the mower off by pressing the GO button for 2 seconds.

2. Remove the Disabling Device.

3. Put on heavy-duty gloves, and place the RoboTool over the blade so that it covers the whole blade.

4. Use the provided Allen tool (comes with a replacing blade) to unscrew the screws while holding the blade with the RoboTool.

5. Replace the blade with a new one (Part No. MRK9100A/MRK9100W).

6. Make sure to close both screws tightly.

The mower:

1. Fully charge the mower in its base.

2. Switch the mower off by pressing the GO button for 2 seconds.

3. Store the mower in dry indoor conditions at ambient temperatures above 0°C.

Base Station:

No winter storage is required for a Base Station. It can be left on the lawn during the winter period.

It is recommended to disconnect the Power Supply from the mains during the winter storage period.

Winter service:

To allow better maintenance and to keep your mower in good condition, it is recommended to bring it to a certified dealer for service prior to winter storage.

1. Make sure the mower is not in the Base Station.

2. Power the mower off by pressing the GO button for 2 seconds.

3. Remove the Disabling Device.

4. Ensure that only a replacement battery of the right type (Part No. MRK9101A/MRK9101W) is used.

5. Warning! Do not use a non-rechargeable battery.

6. For the orientation of the battery with regard to polarity and the method of replacement, refer to the instructions supplied with the replacing battery.

7. For instructions on how to deal with a leaking battery, refer to the “Batteries” section of the provided safety instructions.

8. For disposal, remove the battery from the appliance before scrapping it and ensure it is disposed of safely.

In case of a fault, the ON/OFF indication on the ROBOMOW RX20U panel will light up in red. Press any button to check for an optional sound indication for the fault. The table below will guide you to the corresponding action to take.

If for some reason your ROBOMOW RX20U needs to be rebooted, simply switch it off and on.

When it is required to bring the mower to its factory defaults, you may do so by pressing the GO button for more than 10 seconds (until you hear a long beep and all LEDs start blinking) while the mower is switched off.

The entrance to the Base Station may not be flat. Fill some ground to flatten the lawn around the Base Station to allow a smooth entrance. Make sure the Perimeter Wire is laid according to the installation instructions. Make sure that the Base Station is placed on a relatively level ground.

The blade may be dull. Remove the Disabling Device. Put on heavy-duty gloves and inspect the blade. Replace if needed. Avoid mowing wet grass. For the best cut, operate your ROBOMOW RX20U when the grass is dry. It is recommended not to mow in the early morning hours.

Current mowing times are not enough. Increase the time your ROBOMOW RX20U runs on the lawn. Define additional starting points for a more uniform coverage.

Move the Perimeter Wire to be at a distance of 45 cm / 18″ from any rigid border (like a fence) at the lawn’s edge.

The blade may be damaged or unbalanced. Check if the lawn is free from branches, stones, or other objects that can damage the blade. Replace the blade if needed.

Connected secondary areas: If your lawn has additional areas connected with a passage and the mower is able to drive through it, then you should bear in mind the following rules:

The minimal distance between the wires in such a passage should be 15 cm / 6″.

The minimal width of such a passage should be 57 cm / 22″.

Separated secondary areas: If your lawn has areas that are completely separated (by a fence, sidewalk, pathway, etc.), then you can extend the perimeter wire to cover such secondary areas. When doing this, the two wires should be laid very close to each other (0 cm apart) in the pathway connecting the zones.

Common indications:

Blinking green: The mower is charging in the Base Station.

Blinking red: There is a fault; go to the “Troubleshooting” section of this guide or connect with the mobile app for more information.

Blinking red fast: The perimeter wire is cut. Check the Perimeter Wire’s connection to the Base Station.
