Get started

Choosing the Base Station location

The Base Station is where your mower recharges, and where the Perimeter Wire starts and ends.

Follow these simple guidelines to find a proper location for your Base Station

Rule #1:

Up to 10 meters / 33 feet away from a power outlet

Base Station

Max 10 m / 33 ft

Rule #2:

A min. of 1 meter / 3.3 feet straight wire before, after and aside the base to allow smooth docking

›

meter

›

Rule #3:

Even and ﬂat (up to +/-5% slope)

meter

›

Rule #4:

A minimum of 1 meter / 3.3 feet from a sprinkler head to avoid hitting the mower directly and damaging its internal components

Watch the proper direction of the Base Station relative to the lawn’s edge

Min 1 m / 3.3 ft

The Base Station will be installed at a later stage, after the Perimeter Wire is in place.

TIP

** See additional installation options in Appendix A **

20 21

Lay the wire

Lay the Perimeter Wire (“virtual boundary”), which deﬁnes the working area for the mower.

• Have mower’s package nearby.

• Before you start wiring, use your old mower to cut your grass

TIPS

WHAT YOU’LL NEED

to the height no more than 6 cm (2.5”) one last time. This will make inserting pegs easier and help ensure the mower doesn’t cut the wire.

Hammer

Combination pliers

Cutter

A. Get to know wire distances

Use the RoboRuler to determine a distance, which you should keep between the Perimeter Wire and the lawn’s edge.

If the edge is relatively ﬂat, lay the wire at RoboRuler distance II from it.

> 5cm (2in)

III

Min 1.2m (4ft)

If the edge is a drop or if the ground is sandy/soft, use distance III of the RoboRuler.

When the edge is a wall or a bush, use distance IV of the RoboRuler.

Keep a minimum of 1.2 m (4 ft) if the edge of the lawn borders water.

22 23

B. Make a good start

• Pull out the wire end marked “A” from the Perimeter Wire spool

• Leave a tail of approx. 20 cm / 8”

• Once a tail is made, secure it to the ground where you intend to install your Base Station. Measure the correct RoboRuler distance from the edge:

20cm

SLOPES

TIP

Slopes along the edge

To ensure your mower doesn’t slip off the lawn, especially when the grass is wet, the Perimeter Wire must exclude a slope along the edge of your lawn with an incline of over 10% that is, 10 cm rise per 1 m [4 in rise per 3 ft].

Less than 10% More than 10%

Max 15%

Slopes within the lawn

Your mower can mow areas within the lawn with a slope of up to 15% [15 cm rise per 1 m/0.5 ft rise per 3 ft].

Well done! This was the most complex part of the wire installation. Let’s move on…

24 25

C. Keep laying the wire

Start unwinding the wire counter clockwise around the lawn starting at the Base Station’s location.

Lay the Perimeter Wire loosely along the perimeter as you walk along the lawn’s edge.

• The Perimeter Wire is secured to the ground by the pegs supplied

with the product.

• Pull the wire tight while

hammering the pegs to their ﬁnal depth in the ground.

• Take care not to damage

irrigation pipes.

• Place the pegs every few tens of

centimeters.

• Add pegs where necessary to keep

the wire tight to the ground to avoid damaging it by the mower.

~0.5m

D. Protect obstacles

Hard obstacles

Obstacles that are vertical, rigid and higher than 15 cm (6 in), such as trees or telephone poles, do not need to be protected by the Perimeter Wire. The mower will bump into them and turn away.

Soft obstacles

Objects such as ﬂower beds, ponds, or small trees must be protected by setting Perimeter Islands.

Tree roots, which stick out more than 2 cm above the ground, should be

TIP

Set the Perimeter Wire CLOCKWISE around the obstacle, otherwise the mower will drive into the Perimeter Island or won’t be able to mow the area around it properly.

protected by a perimeter island.

E. What if you have secondary areas?

If your lawn has additional areas as shown below, see Appendix B.

F. Complete wire setup

•

Arrive back to the base location until the two wire ends meet each other

• Put the last peg very close to the ﬁrst one

• Make both wire end the same length. Use a cutter to cut off the remaining

wire.

• Put one of the provided plot connectors on the second wire end

• Use pliers to press the connector and a cutter to cut off the

remaining wire
