Installation

Installation Guide

This chapter explains how to install the Robotic Mower. Please read this completely before you
start the installation.

Introduction

We recommend creating a drawing of your lawn, including all obstacles and how these should be
protected. This makes it easier to find a good position for the docking station and how to correctly place the boundary wire around your garden perimeter protecting bushes, flower beds etc. You will also need some tools, like a hammer and wire cutters, pliers or scissors.

Pre Cut your lawn

Your lawn needs to be prepared correctly, prior to installing the robot lawnmower. Pre cut your lawn to a height of 45 mm.

FIG 2 Pre Cut your lawn

Cutting limitations

The Robotic Mower is equipped with collision sensors. These detect all rigid and solid obstacles
that are higher than 100 mm, such as walls, fences and garden furniture.

When the sensors report an obstacle, the Robotic Mower stops, backs up and then mows in a
different direction. As a long-term solution, it is recommended to lay the boundary wire accordingly using the ruler to protect obstacles and the device. Lay the boundary wire so that the Robotic Mower is not more than 20 m away from the boundary wire at any point in the mowing area.

FIG 3 Cutting limitations

Trees

The Robotic Mower treats trees as common obstacles, but if the roots of the tree are exposed and lower than 100mm, this area should be excluded using boundary wire in order to protect the tree root, cutting blades or rear wheels from damage.

FIG 4 Trees

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 Robotic Mower might try and climb such rocks instead
of recognising them as a barrier. A Robotic Mower getting stuck on such a stone requires user
intervention to restart mowing. Contact with stones can result in damage to the blades.

FIG 5 Stones

Slopes

The Robotic Mower can navigate slopes up to a maximum of 30% incline or decline. The boundary wire should never be perpendicular to an incline of more than 10%. Also, leave strip of at least 2 m between a slope of 10% or steeper and the boundary wire. Otherwise, the higher speed going down the slope may cause the Robotic Mower to go over the boundary wire, especially on wet and slippery ground.

FIG 6 Slopes

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.

FIG 7 Paths, Driveways and Roads

If the driveway and lawn are at the same level, feel free to use the boundary wire to create a
corridor. This allows your Robotic Mower to cross the driveway and reach the opposite lawn.FIG 8 Paths, Driveways and Roads

Uneven lawn surfaces

Uneven lawn areas may cause the blades to touch the ground. We recommend leveling the lawn
before using your Robotic Mower or excluding uneven areas with the boundary wire.

Placing the docking station

Locate the best position for your docking station. Be aware that it needs a permanent connection
to the mains, so take into account the location of the nearest power outlet.

To ensure the Robotic Mower can return to the docking station smoothly, leave 1.5m of straight
wire to the front of the docking station and 30cm to the side facing the cutting area. Use a shaded location for the docking station, as a lower temperature while charging is beneficial to the battery. Important: Place the docking station on an even, flat surface away from ponds, pools or stairs. We recommend suitable protection from the elements, for example a robot port or garage.

Do not place the docking 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.

FIG 9 Placing the docking station

FIG 10 Placing the docking station

If your lawn has a soft or uneven surface, we recommend fortifying the area around the docking
station with a grass protection mesh. Otherwise, the repeated stress of the rear wheels can
damage the turf.

Once the position of the docking station is confirmed and mains electrical connection is laid out,
please do not connect to main power yet. Finish all boundary layout work before connecting the
docking station to the power supply.

Pegging your boundary wire

We strongly recommend mowing the lawn to 45 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.
Use the included ruler to ensure the required 30 cm distance between wire and obstacles.

FIG 11 Pegging your boundary wire

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. Within a
short time the cable will be covered with grass. Since the voltage is only 20 V, there is no risk of
electric shock. Make sure that the hook of the peg and the opening for the cable always face the
demarcated.

FIG 12 Pegging your boundary wire

When first 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 fixing pegs and lay each one on the lawn at approximately the correct distance from lawn edges (30 cm) and obstacles.

Flowerbeds

Use the boundary wire to exclude any flowerbeds from the cutting area. There are two options for the two lengths of boundary wire running between the flowerbed and the outer boundary:

  1. Keep the distance between the parallel wires above 5 cm. This way, the Robotic Mower 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 docking station, it will take the detour around the flower bed. FIG 13 Flowerbeds

  2. Alternatively, keep the distance between the two parallel wires below 5 cm. Do not cross the wires – see below. This way, the Robotic Mower will not recognise the wires and travel across them unhindered. This option requires placing an obstacle on the boundary wire around the flowerbed. 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 flat area of about 1 m x 1 m, without any slopes. This obstacle will allow the machine to exit the circle.

FIG 14 Flowerbeds

Ponds and Pools

While the Robotic Mower 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.

Inventory and garage

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 Robotic Mower might not be able to navigate it from one end to the other.FIG 15 Inventory and garage

Connect the docking station to the boundary wire

Run the boundary wire underneath the front of the docking station and connect the end of the
wire to the left (black) connector marked ‘F’ (front). After you have placed the wire around the
garden then place the other end into right (red) connector marked “B” (back).

FIG 16 Connect the docking station to the boundary
wire

Insert the mains plug into a properly installed socket. Once the blue LED confirms all is OK, test the Robotic Mower’s function. Check the LED regularly to ensure fixing the boundary wire has not affected the connection and signal shows S1 on the charging satation. Then place the Robotic Mower in the working area, a few metres beside the docking station. Set the main power switch to “ON”.

Press the buttons and OK , a few seconds later, the Robotic Mower should automatically return to the docking station by locating and following the boundary wire in anti-clockwise direction. If Robotic Mower fails to dock correctly, move the docking station to a more suitable position.

FIG 17 Connect the docking station to the boundary
wire

Once the device has docked, the symbol will start flashing. This indicates that the battery is
charging correctly.

FIG 18 Connect the docking station to the boundary
wire

After initial installation, the Robotic Mower will remain in the docking station until the battery is
fully charged. Successful docking and charging indicates that you have found a suitable position for the docking station. You should now drive fixing pegs into ground fully.

Take care not to damage or kink the surplus wire stored under the docking station.

FIG 19 Connect the docking station to the boundary
wire

Signal selection
Note: the default signal is S1, no need to change the signal when there isn’t a influence signal
form the neighbors.

FIG 20 Signal selection

If your neighbour is using the samer, will need to keep a distance of 0.5m between you and your
neighbour’s boundary wires to prevent the two devices interfering with each other. Ensure to
position your docking station at least 10m away from your neighbour’s boundary wires and that
both products are using different signals. Please refer to section “Signal setting” in order to select
signal S1 or S2 for your installation.

  1. Press the “signal” button on the charging station, the indicator will be switched to S2.
  2. Turn on your robot mower, push the mower into the charging station, after 5 seconds, the
    mower will be switched S2 automatically.

FIG 21 Signal selection

Note: if your mower can not be switched to the right signal after stay in the charging station, signal switch could be set manually.

  1. Press and hold the button ”6H” and then switch on the mower for 5s, after 5 times beep,
    signal is switched from S1 to S2.

  2. Press and hold the button “3H” and then switch on the mower for 5s, after a long beep,
    signal is switched from S2 to S1.

Troubleshooting

Robotic Mower cannot dock with docking station

  • Check that the boundary wire in front and underneath the charger is in a straight line.
  • Check that the docking station’s position is suitable as explained in this manual.

Robotic Mower runs in circles while mowing or while following boundary wire back to docking station.

  • Verify that no power cable runs parallel and in close proximity the boundary wire. If necessary, reposition the boundary wire.
  • Check if a front wheel is stuck.
  • If a neighbor has a similar Robotic Mower, the signals may interfere. Try setting your docking station and Robotic Mower are set to the alternative boundary signal.
  • Driving motor may be damaged, please contact customer support/

The Robotic Mower is noisy.

  • Inspect the blade fixing screws; tighten if necessary.

  • Inspect the blades for damage; replace if necessary.

  • Grass may be too high. Try increasing the cutting height, or mow the lawn with an ordinary
    lawnmower first.

  • Cutting motor failure, please call after sales service.

Mower remains at or returns to docking station when pressing START button

  • Check if the mower has already completed the programmed working time for that day.
  • Battery is low, let give the Robotic Mower time to charge and try again.
