Additional safety instructions for Robotic Mowers
Do not store anything heavy on the top of the Robotic
Mower or docking station both during storage or when in
use.
Never use the device if the main power switch (11) is
damaged or does not work properly. Never modify the
main power switch. Set the main power switch to OFF
before storage or when the device is not in use. Use the
original packaging when transporting the Robotic Mower,
especially for long distances.
If you need to carry the Robotic Mower from or within the
working area, rst press the STOP button (2) to stop the
device.
Secondly, ensure that the main power switch (11) is
switched OFF before you lift up the Robotic Mower.
Thirdly, close the top cover, and carry the Robotic Mower
using the carry handle (10) at the rear under the mower,
keeping the blade disc away from your body as shown.
Note: The carry handle (10) includes two safety switches.
Lifting the device by the carry handle will trigger the

Lightning Protection
In order to prevent lightning damage to the machine, do
not place the docking station under tall trees.
Operating the machine:
WARNING! This machine can cause serious injury.
Follow instructions below to reduce risk of accident
and injury.
IMPORTANT
READ CAREFULLY BEFORE USE
KEEP FOR FUTURE REFERENCE
Preparation:
• Read the instructions carefully and make sure you
understand them fully. Be familiar with the controls
and the proper use of the machine.
• Never allow children, persons with reduced physical,
sensory or mental capabilities or lack of experience
and knowledge or people unfamiliar with these
instructions use the machine.
• Local regulations may restrict the age of the operator.
Children should be supervised to ensure that they do
not play with the appliance.
• The operator or user is responsible for accidents or
hazards occurring to other people or their property.
• Ensure the correct installation of the perimeter
boundary system as instructed.
• Periodically inspect the area where the machine
is to be used and remove all stones, sticks, wires,
and other debris which could cause damage to the
machine or be unsafe.
• Periodically inspect to see that the blades, blade
bolts and cutter assembly are not worn or damaged.
Replace worn or damaged blades and bolts in sets to
preserve balance.
• On multi-spindle machines, take care as rotating one
blade can cause other blades to rotate.
• Never leave the machine unattended while other
people such as children and pets are in the area.
• Never use the machine to level out uneven patches.
• If the blades no longer cut correctly or if the motor is
overloaded, check all the parts of your equipment and
replace the worn parts. If a more extensive repair is
required, contact the customer service centre.

Use:
• Never operate the machine with defective guards or
without safety devices, for example deectors and/or
grass catchers, in place.
• Do not put hands or feet near or under rotating parts.
• Never pick up or carry the machine while the motor is
running.
• Turn OFF / Power OFF the machine
– before clearing any blockages.
– before checking, cleaning or maintaining the
machine.
• Start the Robotic Mower according to the instructions.
When the main power switch (11) is in the ON position,
make sure you keep your hands and feet away from
the rotating blades.
• Never lift the Robotic Mower or carry it around with
the mains switch is in the ON position.
• Do not let people use the mower who do not know
how it works or behaves.
• Do not put anything on top of the Robotic Mower or
its docking station.
• Do not use the Robotic Mower with defective blade
discs, body, defective blades, screws, nuts etc.
• Avoid operating the machine in wet grass. Doing so
can cause additional wear and tear, and will increase
the amount of cleaning required.
Work interruptions:
• After the machine has been turned off, the cutting
cylinder will continue to rotate for a few seconds.
Keep hands and feet well away.
• Only remove blockages when the machine is standing
completely still.
• Switch off the power when the machine is transported,
lifted or tilted.
• Never leave the machine unattended. Children should
be supervised to ensure that they do not play with the
appliance.
CAUTION!
The following below outlines measures to avoid
damage and harm to both the Robotic Mower and
the people using it.
Taking care of your machine:
• Switch off the power when the machine is to be
carried across uneven surfaces, for example steps.
• Inspect the machine before each use. Never operate
the machine if safety devices (e.g. impact protector,
parts of the cutting facility or bolts) are missing, worn
out or damaged. Check the power cable. To avoid
imbalance, all tools and bolts should be changed as
complete sets.
SAFETY PRECAUTIONS SAFETY PRECAUTIONS

GB GB
• Only use spare parts and accessories that have been
supplied or recommended by the manufacturer. The
use of alien parts results in the immediate loss of all
guarantee claims.
• Ensure that all nuts, bolts and screws are rmly
tightened and that the machine is in a safe working
condition.
• Never try to repair the machine yourself, unless you
have been trained accordingly. All work that has not
been listed in these instructions must only be carried
out by authorised servicing agencies.
• Treat the machine with the greatest care. Always keep
the tool clean. Follow the maintenance instructions.
• Never overload the machine. Always work within
the specied capacity range. Do not use low-power
machines for heavy-duty work. Do not operate the
machine for purposes for which it is not intended.
Electrical safety:
CAUTION!
The following states how to avoid accidents and
injuries due to electric shock:
• Before each use, carry out a visual inspection of the
power and extension cord for any signs of damage or
ageing. Damaged mains power cables increase the
risk of electric shock.
• Connect the machine to a power socket with a
residual-current circuit breaker that has a rated current
of no more than 30 mA.
• Always keep the extension cable well away from the
cutting tools. If the power cable becomes damaged
during work, instantly disconnect the power cable
from the mains. DO NOT TOUCH THE POWER CABLE
BEFORE IT HAS BEEN DISCONNECTED FROM THE
MAINS! Risk of electric shock.
• The supply cord cannot be replaced. If the cord is
damaged the appliance should be scrapped.
• Keep extension cable away from blades and other
moving parts. They may damage the cable and result
in contact with live parts.
• Check that the mains voltage is the same as indicated
on the rating plate.
Maintenance and storage
• Keep all nuts, bolts and screws tight to be sure the
machine is in a safe working condition.
• Replace worn or damaged parts for safety.
• Ensure that only the recommended replacement
cutting blades are tted.
• Ensure that batteries are charged using the charger
supplied or recommended by the manufacturer.
Incorrect use may result in electric shock, overheating
or leakage of corrosive liquid from the battery.
• Servicing of the machine should be carried out
according to manufacturer's instructions.
