The update typically takes 3-5 minutes. If the update has not started after 1 minute, this is due to incorrect use or because the USB stick is damaged. Try using a different USB stick.
Remove the USB stick and replace the battery cover.

Starting the robot lawnmower

• Complete all necessary programming of the robot lawnmower.
• Press the START button (b) to start the robot lawnmower.
• If the current time is within the range from the start time to the start time + the number of work hours for the relevant day of the week, the robot lawnmower will start to cut the grass.
• If the time is outside this range, the robot lawnmower will start to cut the grass. When the robot lawnmower returns to the charging station to recharge the battery, it remains in the charging station until the start time is reached.
• You can stop the robot lawnmower at any time by pressing the red STOP button
• Press the HOME button (c) to get the robot lawnmower to return to the charging station.

Running to the charging station

It is important that the robot lawnmower runs into the charging station correctly when it needs charging, so there is a specific running pattern. When the robot lawnmower needs charging, it runs until it registers the boundary cable. It will follow the boundary cable all the way back to the charging station.

Error messages and troubleshooting

You can see on the display what is wrong if the robot lawnmower has stopped.

The errors are described below.

The control panel cover is open

The robot lawnmower can only operate if the control panel cover is fully closed. Put the cover down once you have finished operating the lawnmower.

The robot lawnmower is stuck

The robot lawnmower reports an error if the obstacle sensors are activated more than 5 times in one minute. Press the OK button to restart the robot lawnmower. If the error occurs repeatedly, investigate whether the boundary cable is laid out correctly, as the error often occurs in places that are too narrow or too cramped for the robot lawnmower to move forward after changing direction. Also check whether there are obstacles such as branches, etc. that may be restricting the robot lawnmower’s freedom of movement.

The robot lawnmower has been lifted

The robot lawnmower will report an error if the lift sensors are continuously activated for 10 seconds. Press the OK button to restart the robot lawnmower. If the error occurs repeatedly, you should check the work area.
Remove any obstacles of over 100 mm, as these may cause the robot lawnmower to roll over. Use a regular lawnmower to cut grass that is taller than 60 mm.

The robot lawnmower has rolled over

If the robot lawnmower rolls over, it stops automatically and reports an error. Reposition the robot lawnmower and press the OK button to start it again. If the error is caused by a steep slope in the work area, change the layout of the boundary cable to avoid the slope. Follow the installation instructions.

The robot lawnmower has been overloaded

The robot lawnmower’s motor is protected against overload. If this error occurs, it is probably because the grass is too tall for the robot lawnmower, or the cutting disc and the wheels are clogged with grass clippings, mud, etc. If the grass is too tall, cut it with a regular lawnmower and clean the robot lawnmower. Press the OK button to restart the robot lawnmower.

Low battery voltage

The battery is flat. Carry the robot lawnmower to the charging station and perform manual charging as described below.

Manual charging

Pull the robot lawnmower out of the charging station. Move the main switch to the OFF position and wait 5 seconds. Note that the lid must be closed. Set the main switch to the ON position and push the robot lawnmower into the charging station again. Do NOT switch the robot lawnmower on using the Power button (a)! If the indicator light on the charging station does not change to red on the first attempt, pull the robot lawnmower out of the charging station and push it back in again. Repeat this until the indicator light turns red. If this does not work after 10-15 times, allow the robot lawnmower to remain in the charging station for an hour before trying again. When the indicator light on the charging station lights up green, charging is complete and the robot lawnmower is fully charged.

Boundary cable signal error

The robot lawnmower will rotate a number of times, stop and report an error if it goes outside the work area or if there is an error with the boundary cable. Check that the robot lawnmower is within the work area and then check the indicator light on the charging station.

| Correct the error.
Lights up red (symbol 4)| The battery is charging.
Flashes of green and red alternately| Maintenance charging of the battery (trickle charging).

In the event of a boundary cable signal error If the robot lawnmower displays the Boundary Error message, there is an error with the boundary cable signal

• The boundary cable is too long (over 250 m).

• The boundary cable is assembled incorrectly, there is moisture in a joint, or an incorrect connector has been used.

• The boundary cable must NOT be stripped when first using the connector provided.

• You can remove the ends of the boundary cable from the charging station and measure the resistance of the boundary cable using a multimeter. A new boundary cable has a resistance of about 2 Ohm per 100 meters.

• If the boundary cable’s resistance measures more than 8-10 Ohm, the robot lawnmower will display a boundary cable signal error

• You can create a test circuit using approx. 10 meters of boundary cable to check that the robot
  lawnmower is working properly. Remember to remove the ends of the real boundary cable from the charging station first. The test circuit’s boundary cable must be connected in the same way as the real boundary cable. Remember that one cable must still be mounted under the charging plate when laying out the test track.

• Correct the error or replace the boundary cable.

Abnormal battery temperature

The robot lawnmower will report an error if the battery temperature during operation is outside the range of 0- 75 °C or during charging is outside the range of 0-45 °C. The robot lawnmower returns to the charging station
and lets the battery return to a safe temperature. The risk of this is greatest in summer when the outside temperature in direct sunlight approaches 35 °C. It may be a good idea to change the start time of the robot lawnmower so that it starts earlier in the day when it is not so hot.

Battery error

The robot lawnmower reports an error if the battery is defective. Replace the battery with a new original battery with the same specifications as the defective battery.

PCB overheating

The robot lawnmower reports an error if the PCB overheats. The robot lawnmower returns to the charging station and allows the PCB to return to a safe temperature. The risk of this is greatest in summer when the outside temperature in direct sunlight approaches 35 °C. It may be a good idea to change the start time of the robot lawnmower so that it starts earlier in the day when it is not so hot.

Charging error

The robot lawnmower has returned to the charging station but it cannot be charged. Check that the charging poles are clean and are correctly inserted into the charging socket on the robot lawnmower.

Skirt error

There are four magnets in the robot lawnmower’s skirt. If any metal comes between the magnets and the skirt, the robot lawnmower may report an error. Remove any pieces of metal. Press the OK button to re-start the robot lawnmower. Other errors and troubleshooting For some errors, an error code will not be displayed.

The display is not on

Press and hold the POWER button (a) for 3 seconds to switch on the robot lawnmower. If the robot lawnmower does not switch on, you will need to carry the robot lawnmower to the charging station. Manually charge it. See the section “Manual charging”.

There is an obstruction on the boundary cable

If an obstruction on or near the boundary cable prevents the robot lawnmower from reaching the charging station, it tries a few times and then stops. Remove the obstruction. Press the OK button to restart
the robot lawnmower.

The robot lawnmower cannot be switched on at the control panel

Check that the main switch (7) is in the ON position.
Carry the robot lawnmower to the charging station and leave it to charge.

The robot lawnmower cannot reach the charging station

Read the installation instructions and make sure that
the charging station is correctly positioned.

The robot lawnmower runs in circles along the boundary cable

There is a live cable in the ground near the boundary cable. Move the boundary cable. If the robot lawnmower has registered the boundary cable more than X times and has moved a few metres away from the most recent registration point, it runs around in a spiral trajectory to improve its coverage of the lawn.

The robot lawnmower is very noisy

If the robot lawnmower makes more noise than normal, check the following

• Are the blades damaged?
• Change all the blades and screws at the same time.
• Are the blades blocked?
• Remove any foreign objects (ropes, plastic, tape, etc.) from the blades.
• If there is noise from the motors that turn the cutting disc or wheels, the robot lawnmower must be inspected by a professional.

Cleaning and maintenance

Caution!

• Always put the main switch in the OFF position before performing any form of cleaning or maintenance on the robot lawnmower.

• Wear work gloves to avoid cutting yourself on the blades.

• Make sure that no water penetrates the robot lawnmower. The robot lawnmower must not be rinsed or washed in running water.

• The robot lawnmower should be cleaned regularly. Wipe the exterior of the robot lawnmower with a damp cloth. Clean the robot lawnmower’s charging socket and the charging poles on the charging station with a small brush or similar, and remove any dirt or deposits with a small piece of very fine sandpaper. Adjust the cutting height to the lowest setting and turn the robot lawnmower upside down. Clean the cutting disc and the blades using a soft brush or a damp cloth with a mild detergent, if necessary. Check that the cutting disc can rotate freely. Remove grass clippings, soil, and mud from the wheels. If any of the parts on the robot lawnmower are damaged, worn, or defective, they must be replaced with the corresponding original parts.

• The blades last for about three months provided that there is no contact with obstacles. Always replace all three blades at the same time so that the cutting disc is in balance.

• Use a screwdriver to dismantle the blades and screw the new ones on.

• Check that the blades can move around these screws once they are fitted to the cutting disc.

• The robot lawnmower is equipped with a maintenance-free lithium-ion battery.

• If the robot lawnmower will not be used for a prolonged period, the battery should be charged fully once every three months.

Winter storage

The robot lawnmower, charging station, and power supply must be put into winter storage at the end of the season and before the frosty weather arrives. The parts must be stored in a clean, dry, and frost-free place. Clean the robot lawnmower as described above. Lubricate the blades with a lubricating spray or similar. Charge the battery manually (see “Manual charging” under point 6) Low battery voltage Push the on/off switch to OFF. The boundary cable can be left in the garden, but its connections should be protected with insulating tape and waterproof grease or similar to prevent corrosion. Remember to charge the battery manually at least every three months while the robot lawnmower is in storage.
