3. INSTALLATION

Initial check

• Preparing the mower for proper use is simple. The process does not take long, though this will depend on the size of your garden.
• This mower is designed to mow on a regular basis, allowing you to keep your garden neat and tidy. In addition, you can programme the operating time to operate at any time and without any limitation.
• When using the mower in public places, the following notice must be displayed: Warning! Automatic lawn mower! Stay away from the appliance! Keep an eye on children!
• First, read this instruction manual carefully. Make a plan of the working area and include all obstacles, so it will be easier to see where the charging station should be placed and where the cables should be routed.
• To mow the lawn for the first time, set the cutting height to the maximum level (50 mm). Place the mower in the working area and run it for a while. Check that the boundary wire is correctly positioned. Also check that the mower returns to the charging station by following the boundary wire. If the mower returns to the charging station without difficulties, this means you can use it normally.

Charging station installation. Figure 3

1. The charging station can be placed next to a tool shed or a house. When laying the boundary wire, leave at least one metre of wire straight and unobstructed in front of the charging station.

ENGLISH

1. The charging station should be placed on a relatively flat surface. Do not place it on an inclined surface and avoid bending the robot's support surface.
2. We recommend that the power supply unit is placed on a wall at a minimum height of 30 cm. The power cable must be outside the working area of the mower.
3. Position the charging station as shown in figure 3, following the indications on the support surface of the charging station, leaving the "IN" area as the area to be cut and "OUT" as the outer area which will be outside the boundary wire and therefore excluded from the cut.
4. Once the charging station is in place, pass the beginning of the boundary wire through the housing in the middle of the charging station to the red terminal at the rear of the charging base.
5. Strip the end of the boundary wire about 10 mm to connect it so that it makes good contact with the red terminal of the charging station. Fig. 4
6. Once the first end is connected, you should continue with the installation of the boundary wire.

Boundary wire installation

If you do not want the mower to pass through certain areas (because there are flowers, bushes, or trees, for example), mark them off with the boundary wire. As shown in Fig. 5, the mower can pass through areas with a minimum width of 0.8 m.

1. When laying the boundary wire, use the distance guide to leave a minimum distance of 35 mm between the wire and obstacles. Each peg should be placed at a distance of about 80 cm. Use the provided distance guide. If the ground is uneven, additional pegs must be fitted to ensure that the wire is fully submerged in the ground. Fig. 6.

Note: if there are any obstacles within the cutting area such as sprinklers, make sure that they do not exceed 1.5 cm in height so that they do not come into contact with the blades. In case the obstacle has a longer length, please make sure to cover these areas with a height higher than the height of the robot or delimit the area with the boundary wire.

1. Ensure that the boundary wire is completely straight, dipped into the ground and that all angles are at least 90^ . Fig. 7

Note: the mower can climb slopes of up to 27% gradient (15°). Avoid letting the mower pass through areas with a higher percentage of slope. Fig. 8

1. To see how to lay the boundary wire according to the slope of your terrain, see figure 8.

2. To close the cutting perimeter, cut off the excess wire and strip the end 10 mm to connect it to the black terminal.

Connecting the charging station to the mains

Connect the boundary wire correctly and then, plug the power supply into the mains socket. The green LED indicator light on the charging station will light up, indicating that the connection has been made correctly and that the circuit with the boundary wire is properly connected.

LED indicator lights	Meaning Action required
No indicator light is on	The charging station is not connected to the mains.	Check that the power cable is properly connected to the charging station, and that the charging station is connected to a suitable power supply.
Steady green The	boundary wire is correctly connected.	This is normal, no action is required.
	The battery is fully charged.
Flashing green The	mower is charging. This is normal, no action is required.
Flashing red The	boundary wire is not connected or is damaged.	Check that both ends of the boundary wire are securely connected.Check the boundary wire for damage.

4. OPERATION

1. Once the installation process is completed, the mower will be ready for use.
2. Press the ⏻ button until the mower switches on. The first time you do this, enter the default PIN code (0000). To do so, press four times ⏻ until number 0 flashes, as shown in Fig. 9. (See section "Changing the PIN code" if you wish to change it).

Note:

• The mower will switch off after 30 seconds if no operation is performed.
• If an incorrect PIN is entered ten times, the mower will beep and then switch off. You can try to enter the PIN again after 50 minutes.
• The robot needs the correct PIN to charge.

• While the robot is charging, it will stop emitting an electrical signal through the cable.

• Press and then so that the mower starts operating.

• Press ☐ and then ☐ for the mower to return to its charging station. Before starting the mower, remember to use the cutting knob to adjust the cutting height (the cutting distance is in relation to the ground).

- The mower will mow the lawn without interruption until its battery level is low. It will then return to the charging station. When fully charged, if it is within the operating time range, it will automatically restart, or remain on the charging station if it is outside the operation time range.

ENGLISH

• The mower will perform cutting cycles when fully charged until it detects a lack of battery power.
• The mower can begin in a second starting area, other than the charging station. If the mower has the second starting area activated (ON), it will proceed to a second area from which it will start after the first full discharge of the battery.
• The mower changes the cutting direction when it detects an obstacle thanks to its shock sensor located on the bumper, so this is common and normal in the mower's operation.
• A number may appear momentarily on the display during the cutting task, this is due to the remaining battery percentage of the mower.

Changing the PIN code

- To change the PIN code, press and hold the START and HOME buttons at the same time for 3 seconds. "PIN 1" will start flashing on the display, which means that you must enter the old PIN. When "PIN 1" is displayed, the first number of the PIN will flash. Use the START or HOME buttons to select the number you wish, and press to confirm the setting. Then, the next number of your old PIN will flash. Repeat the process with the remaining numbers of your old PIN. After that, you can enter a new PIN. In this example, the PIN we want to set is 1234. When you have entered your old PIN, "PIN 2" will start flashing on the display and so will the first number. Do the same to enter the new PIN code of your choice (in this example it is 1234). Will then appear on the display, which means that you have successfully changed the PIN code.

- You can change the PIN code from the App by pairing the mower and following the instructions in the settings menu. If you do not remember the PIN code, try to access the mower by following the pairing process and then change the PIN code. If after these attempts you are unable to do so, please contact the official Cecotec Technical Support Service.

Setting the mower's date

- The year, month, day and time must be set, these are mandatory configuration items. If you do not set these elements correctly, it will influence the programming schedule. These elements must be set in the order: year, month, day, and time.

- To start the configuration, press and hold HOME for 3 seconds. For example, 2020. Use and/or HOME to select the year. Then press OK to confirm and finish the configuration. Next, continue with setting the month and day in the same way, e.g. 08.25 would be 25 August.

- In the meantime, the year will be displayed and then a number to indicate the date, e.g. 08.25 (25 August), Fig. 11

- The time will then be shown on the display, e.g. 13:25. When it flashes, use START or HOME to select the desired number and press to confirm the setting. When the time setting is complete, will appear on the display. Fig. 11

Changing the mower's time and programming the operating range

• The mower's time must be set by pressing and holding the START button for 5 seconds for the mower to follow the programming correctly.
• The default operating range is from 9:00 to 15:00, but you can change it. To do so, press and hold the and buttons at the same time for 3 seconds. For instance, if you want the mower to start operating at 13:25, when 0-:- flashes, use the START or HOME buttons to select the desired time, press the button to confirm the setting. I'd LE will appear on the display, and the mower will automatically start operating at 13:25. You will hear a beep when you do so. Fig. 12

Changing the mower's operating time per day

• The default daily operating time is 3 hours, but you can change it (the minimum time is 1 hour, and the maximum is 24 hours).
• To do this, hold down the OK button for 3 seconds. For example, if you want the operating time to be 06 hours, press the START or HOME buttons to select the number (06) and, when OS R flashes, press OK to confirm the setting. I will appear on the display. The mower will run for 6 hours a day from the start time you have set. You will hear a beep when it starts up. Fig. 13

Changing the days of operation per week

• By default, the mower will operate 5 days a week. You can change this setting to 3, 5 or 7 days. For example, imagine you want to select 3 days per week.
• The number "05" will flash. Press the START or HDME button to select the desired number (03) and then press to confirm the setting. The following will appear on the display:
  3 = Monday, Wednesday, and Friday.
  5 = Monday, Tuesday, Wednesday, Thursday, and Friday.
  7 = Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.
  By default, the mower will cut the edges skirting the boundary wire on Tuesdays and Fridays. Remember that if you have the mower configured with 3 cutting days, Tuesday will not perform edge cutting because it has not programmed that day in its operating range.

Settings

Does my garden need to be Wi-Fi connected?

• Try to ensure that the Wi-Fi connection covers your entire garden.
• If this is not possible, at least make sure that there is a Wi-Fi connection in the area where the charging station is placed. Thus, the information from the mower will be transmitted from the charging station to the app and vice versa.

*Please note that when pairing the charging station, the mower will need to be connected to the internet.

What do I do if the QR code is not recognised?

If you cannot scan the QR code, connect the mower via Bluetooth.

Operation

Why does the mower sometimes hit some obstacles?

- The mower uses a reactive navigation system, whereby it modifies its trajectory according to the obstacles it hits.

How can I restart the mower if I have pressed the STOP button?

- For safety reasons, press + or + on the display.

ENGLISH

Why does the mower sometimes stop mowing in certain areas?

- The mower does not detect obstacles, and after knocking several times it will stop cutting until it detects one area to another in order to continue the task safely.

What is the function of the rain sensor?

- Although the mower can mow when it rains, it is not recommended. If the mower wheels get muddy, the mowing will be less effective, as wet grass is difficult to cut and also tends to stick to the blade disc. So, by default, the sensor sends the command to the robot to charge.

Connectivity

Why can't the mower connect to the Wi-Fi network?

• Make sure that the Wi-Fi frequency is 2.4 GHz.
• The mobile phone and the mower must be connected to the same network. Ensure that Bluetooth and location permissions and features are enabled on the phone. Check if the Wi-Fi indicator light on the mower's display is light up.
• Check if the Wi-Fi icon in the app is activated.
• Check if the Wi-Fi icon on the mower is activated.

Why can't I find the device when I search for it in Bluetooth?

- Search for the device in the app, not in the phone's Bluetooth device list. Be sure to enable location permissions when establishing the Bluetooth connection.

Why does the location permission have to be enabled?

- This is a requirement of the phone's system configuration. Cecotec does not use this information.

Can I connect the mower to a hotspot network?

- Yes

Software updates

How do I know if the mower needs to be updated?

- If there are new software updates, you will receive notifications in the app.

Why do I need to update the mower?

- We are constantly updating features and user experience improvements to optimise the mower's efficiency. We recommend updating the firmware whenever possible to ensure you enjoy the latest enhancements and the best possible user experience.

Maintenance

How do I store the mower in winter?

- It is recommended to store the mower indoors during the winter. Before storing, make sure that the mower is fully charged and switched off.

Can I clean the mower with water?

- Make sure that all screws are secure before cleaning the mower.

- Use a normal water hose to clean the mower. Do not use a high-pressure water gun.

How often should I change the blades?

- If the grass height is high, change the mower blades every 1-2 months.

- If the robot is to be used in areas where the height of the lawn is kept under control, the blades will stay sharp for a longer period of time.
