Thank you for choosing our product.
Robot mowers work by making regular small cuts of the grass to maintain a set height. To do this they must
be able to mow the grass multiple times per day every day. This will keep the grass level constantly in check.
As it is cutting small amounts regularly the clipping will fall to the ground and are not collected. Over time
these small clippings will compost and add nitrogen to the lawn. Eventually this will leave the lawn looking
more green and lush and enhance the general health of the lawn.
FOR HOUSEHOLD USE ONLY

ELECTRICAL SAFETY
•Do not operate the mower in explosive atmospheres, such as in the presence of flammable liquids,
gases or dust. Mowers can sometimes create sparks, which may ignite the dust and fumes.
•Make sure that the connection to the mains has been made in accordance with the laws applicable in
the area. The supplied circuit must be protected by a residual current device (RCD) with an activation
current not exceeding 30 mA.

64
•If the power cord is damaged during use, press the "STOP" button to stop the robotic lawnmower and
unplug the power cord.
•Keep extension cords at a safe distance from moving hazardous parts to prevent damage to the cords,
which can result in contact with live parts.
•Avoid body contact with earthed or grounded surfaces, such as pipes. There is an increased risk of
electric shock if your body is earthed or grounded.
•In the event of a thunderstorm: To reduce the risk of damage to electrical components in the product

replace as necessary.
•Use only genuine replacement parts and cutting blade replacement. This will ensure that the safety of
the mower is maintained.
•Do not attempt to repair any damaged parts on the mower unless you are qualified to do so.
SAFETY EQUIPMENT
•Bumper. In the event of an impact with a solid object, the impact sensor is activated and the robotic
lawnmower blocks the movement in that direction and returns to avoid the obstacle.

65
•Inclinometer. If the robotic lawnmower works on an area with a slope exceeding 37%, the robotic
lawnmower blocks the movement in the given direction and returns so that it does not tip over. In the
event of a rollover or lifting, the robotic lawnmower stops the cutting blade.
•Emergency stop button. At the top of the robotic lawnmower is a button with the word "STOP".
Pressing this button during operation immediately stops the robotic lawnmower and locks the blade.
•Overcurrent protection. Each motor (knife and wheels) is continuously monitored. If the engine
overheats, the robotic lawnmower will stop and signal engine fault on control panel.

PREPARING YOUR LAWN FOR THE ROBOT MOWER

67
Obtuse angles
Curves
Don't cross wires
No right angles
No acute angles
There may be parts of your garden which will be challenging or even impossible for your Robot Mower. Your
Robot Mower will not stray beyond the boundary wire you must lay around your garden.
It will change direction on making contact with things like:
•posts and poles (e.g. washing lines),
•fences and walls around trees
But it will need to be kept away from:
•dug borders,
•trees with exposed roots,
•flower beds,
•ponds and water features,
•excessively uneven terrain.
The wire must be kept taut and never be allowed to loop or cross over itself. Ideally if ground is particularly
uneven the wire can be buried up to 40 mm deep and pegged down to secure. This can be achieved easily
with a manual edging tool. If this is not desired or possible then the wire should be firmly pegged around the
garden with pegs at a minimum of 1 m intervals, keeping the cable taut to avoid it being cut by the mower,
more so at corners and over uneven terrain. The cable should be positioned a minimum of 30 cm from the
edge of the garden, as the mower will overlap the wire, although it will not stray past it.
On corners the wire should not be laid at a sharp angle or right angle, but curved or a series of obtuse
angles. The mower can detect a signal from the wire from as much as 18 m away. It should be noted that
due to this set up some areas of the lawn will not get mowed such as outside the perimeter edges. These can
be maintained using a suitable grass trimmer. If the ground where the wires are to be laid is particularly dry
and the soil hard from lack of rain, it will help to thoroughly water the garden before attempting to lay your
perimeter wire.

68
RECTIFYING OR AVOIDING PROBLEM AREAS OBSTACLES SUCH AS TREE ROOTS ON LAWN
If a tree root is protruding into
the perimeter of your cutting
area it would present a problem
for the mower.
One solution is to take the
perimeter around the tree root,
leaving this area unmowed.
Alternatively, remove the tree
root and fill any resulting uneven
surface, then set the perimeter
over it.
EXCESSIVELY UNEVEN AREAS OF LAWN
A deep enough dip in the surface
of your lawn will also present
problems, possibly causing the
mower“s wheels to lose their grip
and skid.
If you don“t want to avoid
mowing this area, it“s best to fill
it with soil, compact it down and
re-seed it with grass.
If the area is on the perimeter
line this can be pegged out as
normal. If it is within the mowing
area it should no longer be a
problem.
If your mower encounters particularly long grass it may treat it as an obstacle
as it could bump the mower“s obstacle sensor. The grass needs to be at a
reasonable level before the Robot Mower can function correctly.

69
INSTALLING THE CHARGING STATION
Find a location with access to power, ensuring the
mower can leave the charging station in an anti-
clockwise direction. Don“t peg the plate down yet.
The location of the charging station should be flat
and secure, without risk of movement, if placed
next to a border edge that is unstable it can slump
and cause the station to be uneven, this will cause
problems for the mower when returning to
charge.
WARNING: Trailing wires are a trip hazard. Take care when choosing your location.
The boundary wire goes into the
front (1) of the charging station
and comes out at the back (2).
Push the boundary wire into the
tube at the front (1) of the
charging station.
It will emerge at the rear of the
unit (2).

70
You will need to strip the plastic sheath from the
end of the wire before connecting. Twisting the
exposed wires after exposing helps ensure a good
connection.
The charging stand has a hood at the back (shown
in grey) that hinges forwards.
Push the charging station hood forward to uncover
the wiring terminals.
The sprung terminal will need lifting to expose the
hole, ensure the wire is full inserted before releasing
the red terminal clip.

71
When you have completed your boundary wire it
must return to the charging station and be fed up
through the unit and plugs in at the black terminal.
Feed the power lead up through the other side of
the base station.
Pay attention to the cable fittings as there is a
keyway orientation detail to ensure correct
connection.
Push the power cable into place.

72
Then screw on the outer ring to secure the cable in
place and prevent water ingress.
Once the base station has been fully wired, it can be
secured in place with the four screws provided. Use
the allen key provided to screw them in securely
ensuring they are fully inserted and flush with the
station base. Protruding screws can hinder the
mower from locating correctly.
Push the cover back to its original position to cover
the wires and connections from water ingress.
Making sure the power is switched off at the socket,
screw the two charging rods into the holes just
below the cover of the base station. Note: This is
where the LED status indicator is situated. See page
83.

73
LAYING THE BOUNDARY WIRE
Keep the wire straight for at least the first 2 m. This
is to allow the mower to return to the charging
stand with ease.
Place the pegs at intervals of about 1m on straight
and even ground, 30cm to 50cm on bends and
corners. Uneven ground and obstacles will require
more pegs.
The perimeter wire must be kept tight. If it is loose
it may well end up being cut by the mower as it
passes over it.
The perimeter wire must be kept tight. If it is loose it
may well end up being cut by the mower as it passes

74
OPERATING THE MOWER
Place the mower on the base station with the
wheels on the grips and the two pins engaged into
the front of the mower. Note: the mower will
require to be charged to at least 70% capacity
before it will leave its station.
Press the STOP button
This will flip open the control panel and LCD display
cover.
Hold the power button (1) down for three seconds
to activate the LCD display.

75
CONTROL PANEL
CUTTING HEIGHT ADJUSTMENT
1. Open the knob lid.
2. Cutting height can be adjusted from 2.5 cm
to 5.5 cm by rotating the adjustment knob.
GETTING STARTED
Set the cutting height
The first cut of the season or long thick wet grass will need the highest setting (5.5 cm). Gradually reduce to
desired height once all ground has been covered. This may take a few days or a few weeks. If the perimeter
wire is pegged to the surface of the garden rather than buried, it is a good idea to let the wire “bed in” to the
surface of the lawn, during which time it is advisable to keep the mower on an elevated blade setting.
NOTE during first few days of mowing the grass may look stripy or patchy where the mower has covered
/not covered. This is normal and will become even after several days once the full lawn area has been
mowed.

76
First time out
The control panel will ask for setting a PIN code when the first time power on. Please remember the PIN code
you set.
Pressing the start button and closing the flap will cause the mower to start a perimeter circuit after which it
will begin randomly mowing the lawn.
First time out
The first few mows will appear random and unfinished, this is normal. With the multiple passes the mower
makes over time, this will even out, and by using zoning and spiral mowing a desirable effect can be
achieved in less time. These methods are explained on page 79 and 80.
New season mowing
Between mowing seasons when the mower is not operating (during winter months) the grass can become
unkempt and thickets emerge. On new season setup review mowing pass and address any problem areas.
