TIP
The Base Station will be installed at a later stage, after the Perimeter Wire is in place.
** See additional installation options in Appendix A **

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 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.

WHAT YOU'LL NEED

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.

text_image
Edge I II III IV
text_image
II 100 1.5 2.5 3.5 4.5If the edge is relatively flat, lay the wire at RoboRuler distance II from it.

text_image
III 1.0 3.0 10.0 25.0If the edge is a drop or if the ground is sandy/soft, use distance III of the RoboRuler.

text_image
IV > 5cm (2in)When the edge is a wall or a bush, use distance IV of the RoboRuler.

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

natural_image
Diagram of a mechanical component with concentric circles and a pointer, no text or symbols present- 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:

text_image
Diagram illustrating a measurement setup with labeled components and a 20cm scale indicator.
SLOPES
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%

natural_image

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].

text_image
Max 15%Well done! This was the most complex part of the wire installation. Let's move on...
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.

text_image
~0.5m- 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.

natural_image

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.

Frequently Asked Questions

Mower does not dock properly and sometimes misses Base Station's contacts
The entrance to the Base Station is not flat. Fill some ground to flatten the lawn around the Base Station to allow smooth entrance. Make sure the Perimeter Wire is laid according to the installation instructions on the supplied installation template. Make sure that the Base Station is placed on a relatively level ground.

Poor mowing quality
The blade may be dull. Remove the Disabling Device. Put on heavy-duty gloves and inspect the blade. Replace if needed. Avoid mowing wet grass. For the best cut, operate your mower when the grass is dry. It is recommended not to mow in the early morning hours.

Patchy and uneven mowing
Current mowing times are not enough. Increase the time your mower runs on the lawn. Define additional starting points (not applicable to models for lawns under 200 m^2 / 2150 ft^2 ) for a more uniform coverage.

Mower does not depart from base for a long time (not applicable to models for lawns under 200 m² / 2150 ft²)
Use the mobile app to understand the reason for the non-departure.

Mower operates at wrong times (not applicable to models for lawns under 200 m² / 2150 ft²)
Verify that the time on the mower is set correctly. The mower's time is automatically synchronized when it connects with a mobile device.

Mower bumps in a rigid lawn's border too frequently
Move the Perimeter Wire to be at a distance of 45 cm /18" from any rigid border (like a fence) at the lawn's edge.

The mower is very noisy
The blade may be damaged or unbalanced. Check if the lawn is free from branches, stones or other objects that can damage the blade. Replace the blade if needed.
