3.2. YARD FORCE Robotic Mower Basic Operating Principles

The Robotic Lawnmower chooses its direction randomly, which means it will mow your garden completely without leaving behind any uncut part within the area restricted by the chosen boundary.

This boundary is chosen by you through installing supplied Boundary wire. Once the YARD FORCE Robotic Lawnmower detect the boundary wire, it will stop, move backwards, and turn away to cut within a different direction. It is important to ensure that the boundary is complete. Any objects you wish to protect within the boundary, such as Garden Pond, Tree, garden furniture or Flower bed can also be protected by the boundary wire. The Boundary wire must form one complete circuit loop. If the Lawnmower during cutting encounters an obstacle, such as a person, tree, pet or general garden obstacles it will stop, move backwards and turn to mow in another direction.

If you have a corridor inside your lawn boundary, the corridor should be at least 2 meters wide and a max length of 8 m.

UNDERSTANDING THE ROBOTIC MOWER

min. 2 m

max. 8 m

Note: If your YARD FORCE Robotic Lawnmower lifts while hitting an obstacle, the blade disc stops immediately to avoid any potential damage.

3.2.1. Locating the charging station

After approximately 60 min cutting, when your lawnmower battery voltage is low (depending on the kind of grass that is cut and garden complexity), YARD FORCE Robotic Lawnmower will automatically return to the Charging station by locating the closest boundary wire and follow it anticlockwise (without cutting) back to the charging station for a full recharge and when completed robot will start again with next cutting sequence.

UNDERSTANDING THE ROBOTIC MOWER

3.2.2. Recognizing the boundary wire

When the YARD FORCE Robotic Mower approaches any boundary wire, the sensor which are installed in front part of the cover will detect it, but before stopping and turning around, the Lawnmower will overrun the boundary by approximately 20 to 30 cm, so please use this information when you create the layout of your boundary (see later).

20-30 cm

3.2.3. Starting and stopping while mowing

If you want to stop the YARD FORCE Robotic Lawnmower at any time during cutting, please press the STOP button. Once the STOP button is pressed, the Lawnmower will open its keypad top cover, and wait for your further commands. The lawn mower will not start to work until you have closed the top cover.

3.2.4. YARD FORCE Robotic Mower Mowing Limitations

The YARD FORCE robotic lawnmower is programmed by manufacturer to cut 24 hours, 7 days a week but as every garden will be different and if you want to change these settings, it is easy to program this by yourself see instructions which listed at follow chapter. If your neighbor is using a YARD FORCE Robotic Lawnmower also, you need keep a 0.5 m distance between your and neighbor’s boundary wires to eliminate interference. And you need keep your charging station more than 10m from your neighbor’s boundary wires, and you have to set a different boundary signal from neighbor's as signal S1 or S2. Ref. “Signal setting”. Below is a table showing the signal distances for each of the Robot Mowers, please note your model and use this information as your guide when designing the boundary layout.

3.2.5. YARD FORCE Robotic Mower Cutting Information

The YARD FORCE Robotic Lawnmower has 5 cut height settings between 20mm to 60mm. If the grass height is higher than 60cm, you need cut this grass down to at least 60mm, otherwise the load on the unit will be too large and the cutting efficiency will suffer. Use a normal lawn mower or a grass trimmer. Once the installation is completed, the cut can be adjusted to one of the 5 settings of your choice. Always start in a high cutting position and work yourself down to the cutting height you want. This is carried out by lifting the lid shown and adjusting the large rotating dial here. Note do not attempt to raise or lower the cut height during cutting and always.

UNDERSTANDING THE ROBOTIC MOWER

The YARD FORCE Robotic Lawnmower can cut wet grass but wet grass will accumulate on the blade disc and wheels which means more frequent cleaning of unit.

Do not use the YARD FORCE Robotic Lawnmower during lightning or thunder storms

in case of damage to the electronic circuitry, it is recommended to unplug the charging station, and disconnect the boundary wire also if possible. The YARD FORCE Robotic Lawnmower cutting efficiency relies on sharp blades, so please keep them in good condition.

INSTALLATION GUIDE

4. Installation Guide

This chapter explains how to install the YARD FORCE Robotic Lawnmower, please read this completely before you start the installation.

4.1. Introduction

It is recommended that you make a draft of your lawn, including all obstacles and how these should be protected. It makes it easier to find a good position for charging 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.

4.2. Cutting Limitations

For rigid and fixed Obstacles higher than 100mm, such as walls, fences garden furniture etc. the crash sensors reacts immediately YARD FORCE Robotic Lawnmower will STOP, reverse backwards and then turn around to cut in another direction but it is still recommendable to protect the obstacle by creating a boundary around these.

< 400 mm

> 100 mm

INSTALLATION GUIDE

Trees

The YARD FORCE Robotic Lawnmower treats trees as common obstacles, but if some roots of the tree are exposed in your garden and lower than 100mm, this area should be protected in order to prevent tree root, cutting blades or rear wheels profile damage.

Stones

If there is rocks or stones situated within the cutting area, this is also an obstacle and needs to be protected as the robotic mower could ride upwards on.

Slopes

The YARD FORCE Robotic Lawnmower is able to climb uphill and downhill up to a maximum of 40% incline or decline within the cutting area however it is advisable if there is a decline directly towards a boundary wire then this slope should be less than 10 degrees to prevent the Mower from overrunning and pass the boundary wire due to robotic mower downhill running speed, especially if raining or cutting in wet slippery conditions.

Slope should not be steeper than 40% (27

)

INSTALLATION GUIDE

Boundary wire crossing a slope should not exceed 10 degrees if downhill or a flat area to the boundary behind the sloop 2 meter.

min. 2m

Boundary wire

Slope should not be steeper than 10°

Paths, Driveways and Roads

If the lawn boundary is close to a driveway is at a different level as your lawn, you should avoid your robotic lawn mower to run over it to the other lawn. And you need a safety distance of 40cm between the boundary wire and the driveway.

> 40 cm

boundary

If the driveway and lawn are at the same level, then you can let the robotic lawn mower run into the other lawn by passing a corridor created by the boundary wire.

INSTALLATION GUIDE

Uneven lawn surfaces

If the lawn area is very uneven then there is the possibility that blades could touch ground when your YARD FORCE Robotic Lawnmower cuts. If this is possible ensure either to remove this issue by leveling or exclude the area totally with boundary wire.

Flowerbeds

If the Lawn working area includes Flowerbeds, that need to be protected with the boundary wire to be excluded from the working area. If you want the robot to follow the boundary wire around the protected area, the distance between the two parallel boundary wires is more than 10cm.

> 10 cm

Another way, if you want the robot to pass over the two parallel boundary wires. The distance between the two parallel wires should be less than 5 mm. But you need put a obstacle like a stone or a tube on position A . Note: Position A must have a location of flat area, do not set position at any slope. At the side of inside boudary wire, there should be an area 1X1m flat beside position A.

< 5 mm

INSTALLATION GUIDE

Ponds and Pools

If the YARD FORCE Robotic Lawnmower enters into a pond it would have a negative effect to the robotic lawn mower lifetime, so please avoid any ponds by excluding them from the working area by the boundary wire or by adding for additional safety such as a small fence around the pool or pond.

> 10 cm

General Dos and Don’ts

Note ! Boundary wires cannot cross each other. Ensure the boundary wires never cross each other.

Forbidden cross the boundary wire

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 your corridor is narrower than 2m or longer than 8m, you need to carry out your YARD FORCE robotic lawnmower from the corridor. Otherwise you need eliminate this corridor by boundary wire.

Max length of

the corridor

is 8m

Minimum width of

the corridor is 2m

INSTALLATION GUIDE

Examples below show how to arrange the boundary around flower beds or other places you do not want cut, please consider that your bushes and flower beds will change during the different seasons from spring to autumn. An excluded area that is close to the mowing boundary should be kept enough space considering the variable in different seasons.

4.3. Marking out the Robotic Lawnmower’s working area

Now you have understood the basic principles of how the YARD FORCE Robotic Lawnmower works, next step is to mark out the working area with boundary wire by referring to your garden plan already created. This is a very important part of the installation and therefore care must be taken, failure to mark this out correctly will result in many issues later. This boundary wire must be one continuous loop without any break or crossing, which will complete the circuit when connected to charging station.

INSTALLATION GUIDE

Firstly, locate the best position for your charging station, consider the nearest outdoor electricity socket as this needs to be plugged in to mains at all times. Please note the Cable length supplied is 20m.

The charging station item 5 must be placed on a flat surface, at ground level and it can be connected with boundary wire both from front and rear side, meanwhile we need 2m wire straight from front side to make sure the lawnmower can return to charging station smoothly. And also there must be 1m flat space beside the charging station. This will allow the Mower to enter the charging station correctly and enable it to reverse to dock. If possible, locate your charging station in the shade as the battery prefers to be recharged in a cool place.

Note: The charging station area should be flat enough, the pond or footstep is not allowed to exist beside the charging station.

Pay attention to protect cable!

> 1 m

> 2 m

INSTALLATION GUIDE

The following positions are not allowed.

Charging base left and right slope should be no more than 5 degree angle.

We recommend to keep 3 meters straight wire ahead leading into the charging station. If your lawn soil is soft and uneven, we suggest to use 0.5*1m plastic net in front of charging base to avoid the rear wheel digging into the soil ahead of. Once the position of the Charging station is confirmed and mains electrical connection is also can be reached, please do not connect to main power yet. First you need to finish all boundary layout work, and then after that, you can connect to the main power.

INSTALLATION GUIDE

Lightning protection

In order to prevent lightning cause damage to the machine, please don't place charging station under the tall trees.

4.4. Pegging Out the Boundary Wire

Next step is to fix the boundary wire, so locate the boundary wire (item 19), unpack it and locate the free end. Also locate the fixing pegs (item 15) and lay each one on Lawn at approximately the correct distance from lawn edges (40cm) and obstacles. There is a gauge supplied for this (item 17) (Remember to ensure the lawn grass height is maximum of 60mm tall, if not cut it before you start pegging). The boundary wire will be laid on top of the grass there is absolutely no need to dig into the ground. The closer you can lay this boundary wire to the ground level, the safer it will be with no risk of tripping or cutter damage. In a very short time the wire will covered by grass and as the voltage in this wire is only 32V. It is totally safe to human beings and pets.

Cutting area

40 cm

The peg should be knocked into lawn with wire location to boundary outside like shown.

80 cm

INSTALLATION GUIDE

It is recommended to place the pegs at a distance of 80 cm apart approximately, but these can be closer where tight bends are required for accurate cutting, do not fix your pegs permanently when laying out for first time, it is advisable to only partially knock in the pegs with a hammer and ensure the wire location slots are all in same orientation to the outside of boundary. Once all are in correct position, then the boundary wire can be threaded into the slots on pegs one by one around the working area edge. Please start from the charging station and allow an additional 1m of spare wire before cutting off the wire in case a peg needs moving later. When laying out the wire, and adding the pegs, be sure not to tighten the boundary too hard to prevent wire get damaged. Also remember there should be a 2 to 4 meter straight length of wire in front of the charging station in order to allow the robot successfully to dock into charging station. Please be careful also when installing this wire to prevent kinks etc.

Note! If there are hard surfaces where these pegs cannot be used such as a concrete or garden tiles etc. then a screw and plug may be required. If a screw is used then there must be an insulation washer applied.

If the boundary wire needs to be joined for, only use the connectors provided by manufacturer (Item18). See below for some further sketches giving more distance guidelines.

The initial point of boundary

The potential location of charging station

The end point of boundary

1m extra wire for potential adjustment

INSTALLATION GUIDE

Leaving about 1meter extra wire, peg the wire along the boundary from the rear side of the charging station with a distance of the pegs of 80cm. When you finish the layout and back to the charging station, leave another 1meter extra wire and then cut it. Make sure if a square corner is uncounted in your working zone, please do not create a 90deg sharp corner as below, the Mower will turn here anyway and cut this area as it turns, so best leave a 45deg angle in each corner see below.

If the boundary wire is required to protect a flower bed or other obstacle within the Working area then please follow this suggestion. The boundary wire should be laid from the main Boundary in a straight line as shown then around the profile of the obstacle and then back to the main boundary again, the gap between the two boundary wires shown should be as close as possible without crossing. The same peg can be used to fix them; the YARD FORCE Robotic Lawnmower will mow freely over the double wire. If you find you do not have enough Boundary wire left to go around the whole area you wish to protect exclude from cutting or if you need to make some changes later then spare wire can be purchased and it is easy to connect with the provided Boundary wire connectors ( Item 18).

4.5. Prepare the boundary Wire For the Charging Station

After laying the boundary wire you need a decrustation pliers (See below left photo) or scissor to clear the teflon cover of the wire and explode the metal threads for connection to the charging station. A length of 10 - 15 mm metal exploring metal threads are recommended. You may twist the end of the metal threads with your fingers to make it tight for connection.

10 - 15 mm
