3.2. PRODUCT OVERVIEW
3.2.1. GENERAL DESCRIPTION
The robot lawn mower (A) is designed and built to automatically cut garden grass at any time of day and
night.
Depending on the di erent characteristics of the surface to be mowed, the robot lawn mower can be
programmed to work on several zones delimited by a virtual boundary and connected by virtual transfer
paths.
When operating, the robot lawn mower mows the area delimited by the virtual boundary (B) When
the robot lawn mower is close to the virtual boundary (B) or encounters an obstacle (C) it changes its
trajectory according to the chosen navigation strategy.
The robot lawn mower mows the delimited lawn automatically and completely.
The product works using a satellite signal and requires the installation of a docking station (F) with an
integrated satellite reference station (G), which can also be installed separately.The robot lawn mower and
the satellite reference station communicate with each other via 3G/4G modules  tted with SIM cards. The
operating technology of the robot lawn mower is based on data communication between STIGA Cloud and
the robot itself.The subscription fee is mandatory in order to operate the robot lawn mower and is based
on the amount of data required. A smartphone is also required for the product to be used.
Any other usage may be hazardous and harm persons and/or damage things. Improper use includes (for
example, but not limited to): transporting people, children or animals on the machine; being transported by
the machine; using the machine to pull or push loads; using the machine for cutting non-grass vegetation.
NOTE: The subscription fee is mandatory in order to operate the robot lawn mower and is based
on the amount of data required.

4.3. VERIFICATION OF THE INSTALLATION REQUIREMENTS
Below the procedures to check the necessary requirements and prepare the garden before proceeding
with the installation are described.
4.3.1. GARDEN VERIFICATION:
• Carry out a survey of the entire area for a correct detection of the state of the garden, of any
obstacles and areas to be excluded.
• Check whether the lawn to be mowed is even, free of holes, stones or other obstacles and if
necessary carry out any necessary remediation work.
• Level the ground to prevent puddles from forming after a rainfall.
• At the rst installation, the initial height of the grass must be within the operating range of the robot
lawn mower: 20-60mm. If necessary, prepare the garden using a traditional lawn mower.
The robot lawn mower works using a satellite signal. The accuracy of the satellite signal can be aected by:
• The presence of obstacles around the perimeter of the installation or within the work area, such
as: trees with dense foliage, hedges, boundary walls, metal fences, buildings and reective surfaces
such as glass or metal walls.
• Adverse weather conditions, such as dense fog, dense cloud cover, heavy rainfall or snowfall.
In the event of any malfunction, move the satellite reference station to another area free of obstacles and/
or exclude the area from the work area of the robot lawn mower.
4.3.2. CHECKS FOR THE INSTALLATION OF THE DOCKING STATION AND POWER SUPPLY:
ELECTRICAL HAZARD:
A socket must have been prepared
near the installation area to connect
it to electricity. Make sure that
connection to the power supply
network conforms to laws in force of
the Country where it is used.
ELECTRICAL HAZARD:
Do not connect the power supply
to an electrical outlet if the plug or
the cable is damaged.
Do not connect or touch a
damaged cable before it is
disconnected from the power
supply.
A damaged cable can lead to
contact with live parts.
ELECTRICAL HAZARD:
The circuit provided must be
protected by a residual current
device (RCD) with an activation
current not exceeding 30 mA.
Procedure:
• Prepare a at area where the docking station (A) can be positioned, preferably in an area of the
garden where the sky is fully visible and close to an electrical outlet.
• Make sure that the space for installing the docking station is sucient, in order to have an
obstacle-free zone at least 1.5 metres wide and at least 3 metres long in front of it. the ground must
be perfectly at and compact in order to avoid deformation of the surface of the docking station.

• The docking station (A) with satellite reference station (B) must be positioned in an area where the
sky is fully visible. If obstacles such as dense foliage trees, hedges, boundary walls, metal fences,
buildings and re ective surfaces like glass or metal walls are present, the docking station with
satellite reference station must be installed away from these disturbing elements, in a position where
the sky is fully visible.
NOTE: The sky is considered fully visible when clear at an angle of at least 120 degrees in all
directions.
