Version 1 - 2020.12.30
Installing the Boundary Wire
When installing the boundary wire there are a number of situations to consider as described in the table below.
Table 1. Handling Deviations and Obstacles in the Operating Area
Variation Within Operating Area Boundary Wire Planning
Fixed obstacles level with lawn that the mower can traverse (paving
stone paths or similar)
Lay the boundary wire under the paving stones or in the joint between
the paving stones.
Never run the mower over gravel, mulch, or similar material that can
damage the blades.
Fixed obstacles ± 1 cm high Lay the boundary wire 10 cm from the obstacle.
Fixed obstacles 1—5 cm high (small ditches, flower beds, or low
kerbstones)
Lay the boundary wire 30 cm from the obstacle.
Fixed obstacles 5 cm or higher (fences or walls) Lay the boundary wire 35 cm from the obstacle.
Fixed obstacles taller than 15 cm that can withstand a collision (trees
or shrubs)
No measures required; the mower will turn around when it collides
with this type of obstacle.
Fixed obstacles that slope slightly such as stones or large trees with
raised roots
Lay the boundary wire 30 cm from or remove obstacle.
Fixed obstacles that cannot withstand a collision Lay the boundary wire 30 cm from and around the obstacle and then
return it back along the same route.
Long and narrow passages and areas narrower than 1.5 m Install a guide wire.
Borders on a slope, road, precipice, or water Supplement the boundary wire with a physical barrier at least
15 cm high.
Slope up to 30% within operating area No measures required; the mower can operate up to a 30% as long as
the slope is not at the boundary of the operating area.
Slope less than 15% at operating area edge Lay boundary wire as normal.
Slope greater than 15% at operating area edge Do not lay boundary wire unless a fixed obstacle (fence or wall) exists
to prevent the mower from leaving the operating area.
When a part of the operating area outer edge slopes more than
15%; lay the boundary wire 20 cm in on the flat ground before the
beginning of the slope.
NOTE: Slope gradient is defined in percentage units (%). The slope as a percentage unit is calculated as the dierence in elevation in centimetres for
every metre. If, for example, the dierence in elevation is 10 cm, the slope gradient is 10%.

0cm
Installation
Temporarily secure the end of the loop wire to a peg or other object at
the charging station.
Lay out the loop wire in a counter-clockwise direction alone the planned
boundary of the operating area taking into consideration the rules in
Table 1 until you return to the charging station.
If you are going to install a guide wire, create an eyelet with about 20
cm of extra boundary wire at the point where the guide wire will later be
connected.
See Installing a Guide Wire on page 15 for more information.
If the boundary wire is too short, use provided splice and guide wire
connectors to splice additional boundary wire as follows:
1 Insert both ends of the boundary wire into the splice and guide
wire connector. Check that the wires are fully inserted into the
splice and guide wire connector so that the ends are visible
through the splice and guide wire connector.
2 Squeeze down the button on top of the splice and guide wire
connector fully using a polygrip until you hear a click.
Lay down the loop wire reel at the charging station.
Go back around the boundary of the operating area and secure the
boundary wire either using pegs or buried in the ground. Pegs are
recommended since this allows for adjustment during the first few
weeks of operation.
When securing the boundary wire with pegs:
•Cut the grass very low with a standard lawnmower or a trimmer
where the wire is to be laid.
•Lay the boundary wire on the ground and secure with pegs
close together.
•Push or hammer the pegs into the ground.
Do not push the pegs so far into the ground so that they strain the
boundary wire.
When burying the boundary wire:
•Bury the boundary wire 1—20 cm into the ground.
When the boundary wire is completely laid out and secured, install end
loop wire connectors as follows:
1 Open the loop wire connector and place the wire in the loop wire
connector grip.
2 Press the loop wire connectors together using a polygrip until you
hear a click.
Cut o any surplus boundary wire 1-2 cm above each connector.

Version 1 - 2020.12.30
Connect the boundary wire to the charging station as follows:
1 Remove the protective cover on the charging station and thread
the wire behind the tabs into the channel at the rear of the
charging station.
2 Press the connector onto the metal pins on the charging station
(marked with left and right arrows).
NOTE: Make sure the boundary wire to the right of the charging station
is connected to the arrow pointing right and the same for the left side.
Installation

CRAMERTOOLS.COM 15

Version 1 - 2020.12.30
Do not lay the guide wire closer than 30 cm from the boundary wire.
Do not lay the guide wire across the boundary wire.
Lay the guide wire straight under the charging plate in the track intended
for this and then at least 2 m straight out from the front edge of the plate.
Leave as much space as possible to the left of the guide wire (as seen
when facing the charging station).
Use the same cable roll for both the boundary wire and the guide wire.
The guide wire, like the boundary wire, must be secured to the ground
with pegs or buried.
When installing the guide wire on a steep slope, lay the wire at an angle
to the slope so it is easier for the mower to follow the guide wire on the
slope.
Do not lay the guide wire at sharp angles or the mower will have
diculty following it.
Installing a Guide Wire
The mower uses the optional guide wire to find its way back to the
charging station, but also find hard-to reach areas of the operating area.
For example, the guide wire is laid between the charging station and a
remote part of the working area or through a narrow passage.
For narrow passages (less than 3 m) or to shorten search times, a guide
wire is recommended.
Plan the location of the guide wire before laying out the boundary wire.
Run the guide wire to the loop on the boundary wire where the guide
wire is to be connected.
Cut the boundary wire using the combination pliers.
Installation

Version 1 - 2020.12.30
Installation
Insert both ends of the boundary wire as well as the end of the guide
wire into the splice and guide wire connector. Check that the wires are
fully inserted into the splice and guide wire connector so that the ends
are visible through the splice and guide wire connector.
Squeeze down the button on top of the splice and guide wire connector
fully using a polygrip until you hear a click.
Secure the splice and the boundary and guide wires either using pegs
or by burying.
Connect the guide wire to the charging station as follows:
1 Remove the protective cover on the charging station and thread
the guide wire behind the tabs into the channel leading to the
terminals.
2 Connect the guide wire to the contact pin on the charging station
that is labelled G1.
Installing a second guide wire
1 If you have more than one narrow passage or a complicated
garden you can install a second guide wire. To do this, follow the
steps for installing a guide wire except connecting it to the contact
pin on the charging station marked G2.

CRAMERTOOLS.COM 17

Version 1 - 2020.12.30
Pair the mower with Mobile App as instructed in Pairing Mobile App to
Mower on page 19.
Installation
Check the LED indicator on the charging station:
•LED indicator lights up continuously green, if the output voltage
of the power supply is available and the boundary wire is not
interrupted.
The LED indicator does not light up when the output voltage of the
power supply is not available.
If the indicator LED does not show a solid or green light, see Indicator
LEDs on the Charging Station on page 24 for troubleshooting.
Calibrating and Initial Start Up
Secure the charging station to the ground using the five supplied fixing
