1.1.1 Support
For support about the GARDENA product, speak to your GARDENA service.
1.1.2 Product description
Note: GARDENA regularly updates the appearance
and function of the products. Refer to Support on page 3.
The product is a robotic lawn mower. The product has a battery power source and cuts the grass automatically. It continuously alternates between mowing and charging. The movement pattern is random, which means that the lawn is mowed evenly and with less wear. The boundary wire and the guide wire controls the movement of the product within the work area. Sensors in the product senses when it is approaching the boundary wire. The front of the product always passes the boundary wire by a specific distance before the product turns around. When the product hits an obstacle or approaches the boundary wire the product selects a new direction.
The operator selects the operation settings in the GARDENA Bluetooth® App or with the keys on the keypad. The app and the LED status indicator lamps show the selected and possible operation settings, and the operation mode of the product.
1.1.2.1 Mowing technique
The product is emission free, easy to use and saves energy. The frequent cutting technique improves the grass quality and decreases the use of fertilizers.
Collection of grass is not necessary.
1.1.2.2 Find the charging station
The product operates until the battery state of charge is low. Then it follows the guide wire to the charging station. The guide wire is laid from the charging station towards, for instance, a remote part of the work area or through a narrow passage. The guide wire is connected with the boundary wire and makes it much easier and faster for the product to find the charging station.
1.1.2.3 GARDENA Bluetooth® App
The product can be operated with the keypad on the product and use the factory settings of the product.
To adjust the settings of the product the GARDENA Bluetooth® App is used. The product can be controlled remotely with Bluetooth® within short range.

CAUTION: Use original spare parts and installation material.
3.2 Main components for installation
The installation involves the following components:
•A robotic lawn mower that mows the lawn automatically.
•A charging station, which has 3 functions:
•To send control signals along the boundary wire.
•To send control signals along the guide wire so that the product can follow the guide to specific remote areas in the garden and can find its way back to the charging station.
•To charge the product.
•A power supply, which is connected to the charging station and a 100-240V power outlet.
•Loop wire, which is laid around the work area and around objects and plants that the product must not run into. The loop wire is used both as boundary wire and guide wire.
3.3 General preparations
CAUTION: Holes with water in the lawn can cause damage to the product.
Note: Read through the Installation chapter before
beginning the installation. How the installation is done affects how the product performs. It is therefore important to plan the installation carefully.
•Make a blueprint of the work area and include all obstacles. This makes it easier to see the ideal positions for the charging station, the boundary wire and the guide wire.
•Make a mark on the blueprint where to put the charging station, the boundary wire and the guide wire.
•Make a mark on the blueprint where the guide wire connects to the boundary wire. Refer to To install the guide wire on page 18.
•Fill in holes in the lawn.
•Cut the grass before you install the product. Make sure that the grass is maximum 4 cm / 1.6 in.
Note: The first weeks after installation the perceived
sound level when cutting the grass may be higher than expected. When the product has cut the grass for some time, the perceived sound level is much lower.
3.4 Before the installation of the wires
You can select to attach the wires with stakes or bury them. You can use the 2 procedures for the same work area.
CAUTION: If you use a dethatcher in
the work area, bury the boundary wire and the guide wire to prevent them from damage.
3.4.1 To examine where to put the charging station
•Keep a minimum 2 m / 6.6 ft. of free space in front of the charging station. Refer to To examine where to put the guide wire on page 16.
•Keep a minimum of 30 cm / 12 in. of free space to the right and left of the center of the charging station.
•Put the charging station near a power outlet.
•Put the charging station on a level surface.
•The baseplate of the charging station must not be bent.
12 - Installation |
1585 - 004 - 03.03.2021 |
CAUTION: Make sure that the blades
on the product do not cut the low-voltage cable.
MAX 3 CM/1.2" 
CAUTION: Do not put the low-voltage
cable in a coil or below the charging station plate. The coil causes interference with the signal from the charging station.
MAX +/- 2 CM / 0.8 IN.
•If the work area has two parts separated with a steep slope, we recommend to put the charging station in the lower section.
•Put the charging station in an area with protection from the sun.
•If the charging station is installed on an island, make sure to connect the guide wire to the island. Refer to To make an island on page 15.
3.4.2 To examine where to put the power supply
WARNING: Do not cut or extend the
low-voltage cable. There is a risk of electrical shock.
•Put the power supply in an area with a roof and protection from the sun and rain.
•Put the power supply in an area with good airflow.
•Use a residual-current device (RCD) with a tripping current of maximum 30 mA when you connect the power supply to the power outlet.
Low-voltage cables of different lengths are available as accessories.
3.4.3 To examine where to put the boundary wire
CAUTION: There must be a barrier of
minimum 15 cm / 6 in. in height between the boundary wire and water bodies, slopes, precipices or public roads. This will prevent damage to the product.
CAUTION: Do not let the product operate on gravel.
CAUTION: Do not make sharp bends when you install the boundary wire.
CAUTION: For careful operation
without noise, isolate all obstacles such as trees, roots and stones.
The boundary wire should be put as a loop around the work area. Sensors in the product senses when the product approaches the boundary wire, and the product selects another direction. All parts of the work area must be maximum 15 m / 50 ft. from the boundary wire.
To make the connection easier between the guide wire and the boundary wire, it is recommended to make an eyelet where the guide wire will be connected. Make the
1585 - 004 - 03.03.2021 |
Installation - 13 |
eyelet with approximately 20 cm / 8 in. of the boundary wire.
• Put the boundary wire 30 cm / 12 in. (C) from an obstacle that is 1-3.5 cm / 0.4-1.4 in. high.
Note: Make a blueprint of the work area before you install the boundary wire and guide wire.
•Put the boundary wire around all of the work area
(A). Adapt the distance between the boundary wire and obstacles.
•Put the boundary wire 35 cm / 14 in. (B) from an obstacle that is more than 3.5 cm / 1.4 in. high.
•Put the boundary wire 10 cm / 4 in. (D) from an obstacle that is less than 1 cm / 0.4 in. high.
•If you have a paving stone path that is in level with the lawn, put the boundary wire below the paving stone.
Note: If the paving stone is minimum 30 cm / 12
in. wide, use the factory setting for the Drive Past Wire function to cut all the grass adjacent to the paving stone. Refer to Drive Past Wire function on page 21.
•If you make an island, put the boundary wire that runs to and from the island near together (E). Put the wires in the same stake. Refer to To make an island on page 15.
•Make an eyelet (F) where the guide wire is to be connected to the boundary wire.
14 - Installation |
1585 - 004 - 03.03.2021 |
3.4.3.1 To put the boundary wire in a slope
The product can operate in 25% slopes. Slopes that are too steep must be isolated with the boundary wire. The gradient (%) is calculated as height per m. Example: 10 cm / 100 cm = 10%.
•For slopes steeper than 25% inside the work area, isolate the slope with boundary wire.
•For slopes steeper than 10% along the outer edge of the lawn, put the boundary wire 20 cm / 8 in. (A) from the edge.
•For slopes adjacent to a public road, put a barrier of minimum 15 cm / 6 in. along the outer edge of the slope. You can use a wall or a fence as a barrier.
3.4.3.2 Passages
A passage is a section that has boundary wire on each side and that connects 2 parts of the work area. The distance between the boundary wire on each side in the passage must be a minimum of 60 cm / 24 in.
Note: If a passage is less than 2 m / 6.5 ft. wide, install a guide wire through the passage.
The recommended minimum distance between the guide wire and the boundary wire is 30 cm / 12 in. The product always runs to the left of the guide wire as seen facing the charging station. It is recommended to have as much free area as possible to the left of the guide wire (A).
3.4.3.3 To make an island
CAUTION: Do not put a section of
boundary wire across the other. The sections of boundary wire must be parallel.
CAUTION: Do not put the guide wire across the boundary wire.
CAUTION: Isolate or remove obstacles
that are less than 15 cm / 5.9 in. in height. Isolate or remove obstacles that slope slightly, for example, stones, trees or roots. This will prevent damage to the blades of the product.
To make an island, isolate areas in the work area with the boundary wire. We recommend to isolate all stable objects in the work area.
