carried across uneven surfaces, for example steps.
SAFETY PRECAUTIONS SAFETY PRECAUTIONS
• 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 and starting
lever (if any) for damage. To avoid imbalance, all tools
and bolts must be changed as complete sets.
• 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 specied 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:
• 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. Should the power cable become
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.

SAFETY PRECAUTIONS SAFETY PRECAUTIONS
• 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.
• In the event of leakage of electrolyte, ush with water/
neutralising agent, seek medical help if it comes into
contact with the eyes.
• Store the appliance with battery pack fully charged at
room temperature (around 20ºC).
• Every deep discharge cycle decreases the capacity
of battery pack. To prolong battery life, it is
recommended to charge the battery every 6 months
over extended periods of time without use.
Transport
The original packaging should be used when transporting
the Robomower over long distances.
To safely move from or within the working areas:
• Press the STOP button to stop the mower.
• Move the main switch button to the OFF position if you
intended to carry the mower.
• Carry the Robomower using the handle below at the rear.
Carry the mower with the blade disc away from the body.
Robomower basic operating principles
• The Robomower chooses its working direction randomly.
It will mow your garden completely without leaving
behind any uncut part within the area restricted by the
chosen boundary.
• You dene the work area by installing the supplied
boundary wire. Once the Robomower detects the
boundary wire, it will stop, move backwards and
continue mowing in a different direction. It is important to
ensure that the boundary is complete. Any objects you
wish to protect within the boundary, such as a garden
pond, trees, garden furniture or ower beds can also be
protected by the boundary wire. The boundary wire must
form one complete loop. If the Robomower encounters
an obstacle, such as a person, tree, pet or other general
garden obstacles, it will stop, move backwards and
continue mowing in a different direction.
20 21
SAFETY PRECAUTIONS SAFETY PRECAUTIONS
• If you need a narrow corridor to connect two patches of
lawn within the boundary, the corridor should be at least
2 metres wide and max. 8 m long.
min. 2 m
max. 8 m
Note: If your Robomower loses ground contact while
hitting an obstacle, the blade disc will stop immediately
to avoid any potential damage.
Locating the charging station
• When the battery is running low, the Robomower
will automatically return to the charging station. It
will approach the closest boundary wire and follow it
anticlockwise (without cutting) back to the charging
station. When fully charged, the Robomower will
automatically resume the interrupted working cycle. The
launch direction from the charging station - clockwise - is
hard-wired into the design and is impossible to change.
Recognising the boundary wire
• Note that before stopping and changing the direction,
the Robomower will overrun the boundary wire by 10
to 20 cm. Please keep this in mind when planning the
boundary wire installation.
22 23
SAFETY PRECAUTIONS SAFETY PRECAUTIONS
10-20 cm
Starting and stopping while mowing
• If you want to stop the Robomower at any time during
cutting, please press the STOP button (2). Pressing the
STOP button will also open the top cover, providing
access to the control interface. The Robomower will not
start working again until you have closed the top cover.
Robomower mowing limitations
• Out of the box, the Robomower is set to work 7 days a
week. You can adjust the daily working time to match
your garden.
• In case a neighbor is using the same Robomower, you
need keep a 0.5 m distance between your and your
neighbour's boundary wires. Otherwise, the two devices
might interfere with each-other. Additionally, keep
your charging station more than 10 m away from your
neighbour's boundary wires. Last not least, ensure that
the adjacent boundary wires use different signals. Please
refer to section "Signal setting" in order to select signal
S1 or S2 for your installation.

Robomower cutting information
• The Robomower has a cutting height setting between
20 mm to 60 mm. If the grass height exceeds 60 mm,
cut it to 60 mm or below before using the Robomower.
Otherwise the load on the unit will be too large and the
cutting efciency will suffer, we recommend using an
ordinary lawn mower or trimmer. Once the installation is
complete, adjust the cutting height to the desired setting.
Always start in a high cutting position and work your way
down to the cutting height you want. Before adjusting
the cutting height, always press the STOP button (2) to
interrupt the cutting. Then turn the large dial to adjust the
cutting height.
• Do not use the Robomower during lightning or thunder
storms. In case of damage to the electronic circuitry,
unplug the charging station and - if possible - disconnect
the boundary wire.
The Robomower cutting efciency relies on sharp
blades, so please keep them in good condition.
Note: Only adjust the cutting height while the
Robomower is switched off.

ASSEMBLY INSTRUCTIONS ASSEMBLY INSTRUCTIONS
Installation Guide
This chapter explains how to install the Robomower. Please read this completely before you
start the installation.
Introduction
We recommend creating a draft of your lawn, including all obstacles and how these should
be protected. This makes it easier to nd a good position for the charging station and how
to correctly place the boundary wire around your garden perimeter protecting bushes, ower
beds etc. You will also need some tools, like a hammer and wire cutters, pliers or scissors.
Cutting limitations
The Robomower is equipped with collision sensors. These will detect any rigid
and xed obstacles higher than 100 mm, such as walls, fences and garden furniture.
When triggered, the Robomower will stop, reverse backwards and then continue mowing in a
different direction. Still, protecting the obstacles running the boundary wire accordingly is the
recommended long-term solution.
< 400 mm
Trees
Uneven lawn areas may cause the blades to touch the ground. We recommend leveling
lawn before using your Robomower or excluding uneven areas with he boundary
wire.
Stones
We recommend clearing the lawn of small (less than 100 mm high) rocks and stones and
any stones with a round or sloped edge. The Robomower might try and climb such
rocks instead of recognising them as a barrier.
A Robomower getting stuck on such a stone requires user intervention to restart mowing.
Contact with stones can result in damage to the blades.
> 100 mm
Slopes
The Robomower can navigate slopes up to a maximum of 50% incline or decline.
Slope should not be steeper
than 50% (27°).
28 29
ASSEMBLY INSTRUCTIONS ASSEMBLY INSTRUCTIONS
The boundary wire should never run perpendicular to a gradient of more than 10°.
Likewise, please allow a corridor of at least 2m between a 10° or steeper slope and the boundary
wire. Otherwise, the faster downhill speed may cause the Robomower to
overshoot the boundary wire, especially on wet and slippery ground.

Paths, Driveways and Roads
If an elevated driveway crosses your lawn, better keep it outside the boundary wire.
Please allow a safety distance of 40 cm between driveway and boundary wire.
If the driveway and lawn are at the same level, feel free to use the boundary wire to create a
corridor. This allows your Robomower to cross the driveway and reach the opposite lawn.

ASSEMBLY INSTRUCTIONS ASSEMBLY INSTRUCTIONS
Flowerbeds
Use the boundary wire to exclude any owerbeds from the cutting area. There are two options
for the two lengths of boundary wire running between the owerbed and the
outer boundary:
1) Keep the distance between the parallel wires above 10 cm. This way, the Robomower will
recognise the boundary wire as an ordinary obstacle. When cutting, it will "bounce" off it as
usual. When following the boundary wire back to the charging station, it will take the detour
around the ower bed.
> 10 cm
2) Alternatively, keep the distance between the two parallel wires below 5 mm. Do not
cross the wires - see below. This way, the Robomower will not recognise the wires and
travel across them unhindered. This option requires placing an obstacle on the boundary
wire around the owerbed. Place the obstacle, e. g. a large rock or pole, near position A
indicated on the below illustration. The obstacle must be surrounded by a at area of about
1 m x 1 m, without any slopes. This obstacle will allow the machine to exit the circle.
Ponds and Pools
While the Robomower is protected against rain and spray water, being submerged is likely to
cause severe damage to the electronic parts.
Therefore, it is imperative to exclude any pools from the cutting area. For added safety, we
recommend placing a fence around the pool.
> 10 cm
General Dos and Don’ts
Do not run the boundary wire parallel directly above an ordinary power cable.
The power cable's electric eld may distort the boundary signal.
Never cross two boundary wires! This will distort the radio signal and cause erratic behavior
of the Robomower.
Never cross the wires!
If you have created a boundary corridor inside your working area, the corridor should be at
least 2 m wide and a max length of 8 m.
If a corridor is too narrow or too long, the Robomower might not be able to navigate it from
one end to the other.

ASSEMBLY INSTRUCTIONS ASSEMBLY INSTRUCTIONS
Keep in mind that owers, bushes and surrounding shrubbery will change in size over a season.
Please keep sufcient space between boundary wire and other plants to avoid interference yeararound.
Marking out the Robomower's working area
You have now understood the basic principles of how the Robomower works. The next
step is to mark out the working area with boundary wire by referring to your garden plan.
This is a very important part of the installation, so please take care.
Starting from the charging station, the boundary wire must be one continuous loop without
any breaks or crossings. Connecting the end to the charging stations second connector
will complete the circuit.
Where appropriate, use the included ruler to check the 40 cm required distance.
Firstly, locate the best position for your charging station. Be aware that it needs a
permanent connection to the mains, so take into account the location of the nearest power
outlet.
The included supply cord has a length of 9 m.
The charging station (5) must be placed on a at surface, at ground level.
Both the front and back of the charging station must be accessible to the boundary wire. To
ensure the Robomower can return to the charging station smoothly, leave 2m of straight wire
to the front of the charging station and 1m to the side facing the cutting area. Use a shaded
location for the charging station, as a lower temperature while charging is benecial to the
battery.
Important: Place the charging station on an even, at surface away from ponds, pools or
stairs.
We recommend suitable protection from the elements, for example a robot port or garage.
Pay attention to protect cable!
34 35
> 1 m
> 2 m
ASSEMBLY INSTRUCTIONS ASSEMBLY INSTRUCTIONS
Do not place the charging station too close to a slope, such as at the top of a hill or the
bottom of a furrow. Avoid left and right inclination in excess of 5 degrees.
5> <5
If your lawn has a soft or uneven surface, we recommend fortifying the area around the
charging station with a grass protection mesh. Otherwise, the repeated stress of the rear
wheels can damage the turf.
Once the position of the charging station is conrmed and mains electrical connection is
laid out, please do not connect to main power yet. Finish all boundary layout work before
connecting the charging station to the power supply.
Pegging out the boundary wire
We strongly recommend mowing the lawn to 60 mm or less before laying out the boundary
wire. Burying the boundary wire is entirely optional. Still, the closer to the ground you lay out
the boundary wire, the lower the chance of tripping over it or damaging it when mowing the
lawn.
In a very short time, the wire will be covered by grass. As the voltage is only 32 V, there
is no risk of electric shock.
Unpack the boundary wire (18) and locate the free end. Mark the desired path of the boundary
wire with the xing pegs (15).
Use the included ruler (16) to to ensure the required 40 cm distance between wire and
obstacles.
The recommended distance between two pegs is about 80 cm in straight lines, and less in
tight curves. Note that the pegs' hook and wire slit always faces the outside of the boundary.
When rst planting the pegs, do not drive them fully into the ground. Use a light hammer
to drive them in a little bit. Also locate the xing pegs (item 15) and lay each one on the lawn
at approximately the correct distance from lawn edges (40cm) and obstacles.
There is a gauge supplied for this (item 16).
Cutting area
40 cm
80 cm
Once all pegs are in position, lay out the boundary wire. Start from the charging station. Run
the wire through the peg's hook and wire slit one-by-one. Do not tighten the boundary wire
too much to prevent wire damage. Carefully prevent any kinks, knots, etc.
When cutting the wire, we recommend leaving at least 1 m spare wire to allow for
adjustments.
Note: The pegs are not suitable for xing the boundary wire on hard surfaces, e.
g. when running the boundary wire across a driveway. Instead, use appropriate
screws and plugs. Be sure to use insulation washers to protect the wire
insulation.
The pegs should be knocked into lawn
with wire location to boundary outside
like shown.

CLEANING/MAINTENANCE
CLEANING/MAINTENANCE
Work that has not been described in these instructions must be carried out by a
servicing agency authorised by the manufacturer. Only use original parts.
Maintenance
Check and clean your Robomower regularly and replace worn parts if necessary. Preferably
use a dry brush, a damp cloth or a sharpened wooden piece.
Never use ushing water.
Following these maintenance instructions can extend your Robomower's service life.
Battery Life
The Robomower has a maintenance free Li-ion battery, with an estimated life of more than 2
years (depending on treatment and usage).
Winter Storage
During winter, keep your mower, charging station and power supply in a dry place.
We recommend a shed, garage or preferably store it indoors.
Prepare your device for winter storage as follows:
1. Fully recharge the battery.
2. Set the main power switch to "OFF".
3. Thoroughly clean your Robomower.
4. Unplug the power supply from the mains outlet.
5. Disconnect the power supply from the charging station.
6. Disconnect the boundary wire from the charging station. Lift up the charging station, and
clean it. The boundary wire can remain outside. However, it is imperative to protect the
wire against corrosion. We recommend a water-free grease or suitable sealing tape.
If available, repack the product in the original packaging.
Alternatively, our service centre offers a winter service for your device. This will include a
check-up of all parts and - if available - a software upgrade.
Preparing for spring
After winter storage, please clean the charging contacts on both the Robomower and the
charging station.
Use a ne abrasion paper or a brass brush; this will help to achieve the best charging
efciency and avoid any charging interference.
Cleaning and Maintenance
It’s important to keep your Robomower clean.
The mower will deal with slopes easier when the wheels are clean. Sharp cutting blades need
less power and create cleaner cuts.
Remember to turn off the main power switch (11) before any maintenance. Use protective
gloves when handling the blades! Never use a high pressure washer, garden hose or running
water when cleaning the device.
Cleaning the mower body
As your Robomower is battery powered you need take care when cleaning. Remove rough
dirt with a soft brush. Use a manual water spray with mild household detergent for intensive
cleaning. Wipe off any residue after cleaning with a moist rag.
48 49
CLEANING/MAINTENANCE CLEANING/MAINTENANCE
Cleaning the underside
Ensure the main power switch (11) is in OFF position. Wear protective gloves. Turn the
Robomower onto its side to expose its underside. Clean the blade disc and frame using a soft
brush or damp cloth. Rotate the blade disc to make sure that it moves freely, and check that the
blades can turn on their pivots and no grass is obstructing them.
Clean the contact pins and the charging strips
Using wire wool, metal cleaner or very ne grade emery paper, clean the contact pins and
the charging strips on your mower and charging station. Remove any debris, leaves, or grass
clippings around the contact pins and charging strips to ensure efcient charging.
Reversing or replacing the blades
WARNING!
Ensure the Robomower is completely shut off before cleaning, adjusting or replacing
the blades. Always wear protective gloves.
WARNING!
To ensure maximum cutting efciency and safety, always use recommended
replacement blades and blade mounting parts when replacing.
Your Robomower has three blades, xed to the blades disk.
Unless damaged by hard obstacles, these blades can last for up to ve months of everyday
use.
Weekly inspection of the blades and the xing screws is required. Note that the blades are
double-edged. Once the rst side is blunt, loosen the xing screw. Turn the blade upsidedown and x it again with the xing screw. After tightening the xing screw, verify that the
blade can rotate freely around the screw.
A set of spare blades is included with the Robomower. More are available from customer
support. The blade's spare part number is 846210.
Only use original spare parts. For best performance and avoiding imbalance, always turn or
replace all three blades at the same time.
Replacing the battery
While the actual battery life will depend on usage and environmental factors, the typical
service life is several years. Spare batteries are available from customer support. To
replace the battery, please follow the instructions below.
1) Ensure the main power switch (11) is turned OFF. Clean the underside as instructed.
2) Set the Robomower to the lowest cutting height.
3) Turn the mower upside-down. Remove the 5 screws xing the battery compartment's lid.
Note one screw is partially covered by the blade protector and is only accessible through
a service hole.
4) Pull out the battery and disconnect it from the Robomower.
5) Carefully clean the lid and the edge of the battery compartment. Debris may allow
excessive water entering the battery compartment, causing major damage to the device.
6) Connect and insert the replacement battery, close the compartment and x the lid with 5
screws. Do not turn on the Robomower before placing it back on its wheels - beware of
sharp blades!
