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.
12
15
17
16
13 14
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.

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 40 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.
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 10 to 20 cm, so
please use this information when you create the layout of your boundary (see later).
10-20 cm
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.

from current time every day 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 10 m 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”.

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 60 cm, you need cut this grass down to at least 60mm,
otherwise the load on the unit will be too large and the cutting efciency 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.
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 efciency relies on sharp blades, so please
keep them in good condition.

INSTALLATION GUIDEINSTALLATION 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 nd a good position for 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.
4.2. Cutting Limitations
For rigid and xed Obstacles higher than 100 mm, 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
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 prole 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.
> 100 mm
Slopes
The YARD FORCE Robotic Lawnmower is able to climb uphill and downhill up to a
maximum of 50 % 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.
18 19
Slope should not
be steeper than 50 % (27

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
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
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.

20 21
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 at area, do not set position at any slope. At the
side of inside boudary wire, there should be an area 1X1m at beside position A.
< 5 mm
INSTALLATION GUIDEINSTALLATION 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.
Examples below show how to arrange the boundary around ower beds or other places
you do not want cut, please consider that your bushes and ower 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.
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 8 m
Minimum width of
the corridor is 2 m

INSTALLATION GUIDEINSTALLATION 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 9m.
The charging station item 5 must be placed on a at 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 at space beside the charging station. This will allow
the Mower to enter the charging station correctly. 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 at enough, the pond or footstep is not allowed
to exist beside the charging station.
The following positions are not allowed.
5> <5
Pay attention to protect cable!
24 25
Charging base left and right slope should be no more than 5 degree angle.
We recommend to keep 2 meters straight wire ahead leading into the charging station. If
your lawn soil is soft and uneven, we suggest to use 0.5*1 m 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 conrmed and mains electrical connection is
also can be reached, please do not connect to main power yet. First you need to nish all
boundary layout work, and then after that, you can connect to the main power.

INSTALLATION GUIDEINSTALLATION 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 xing 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.
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 x your pegs
permanently when laying out for rst 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).
