Robomow safety features WARNING! Robomow is equipped with numerous built-in safety features. However, the mower is a hazardous device with a sharp blade, which can cause major injury to anyone who comes in contact with it. Therefore, it is absolutely forbidden to be on the lawn while the mower is working. Alternatively, halt the mower’s operation when people (especially children) or pets are to stay or play on the lawn. A.
D. Tilt Sensor If the mower is tilted up towards a vertical position, the blade will stop immediately. E. Obstruction Sensor Robomow detects interfering obstacles in its way during operation. When the mower collides with an obstacle, it will stop the rotation of the blade immediately, will stop movement in that direction and reverse itself away from the obstacle. F. Emergency Stop Button Pressing the STOP button at any time during operation will stop the mower and the blade immediately. G.
Let’s get started.
Installation Congratulations on purchasing Robomow! You are just a few steps away from meeting your best team player. Very soon you will come to count on your Robomow to do a perfect job. A preinstalled Perimeter Wire will set the boundaries (a “virtual wall”) for your Robomow. The Perimeter Wire will be laid around the edges of your lawn and objects that you want to protect. Robomow will move randomly within its working area, as defined by the Perimeter Wire.
So where are we heading? Correct installation of your Robomow will ensure maximum results. This is what it takes to prepare your Robomow to do a perfect job for you.
This is what you find in the box Robomow RX model Base Station Your new Robotic Mower This is where Robomow recharges Wire Pegs* 150 pcs. Perimeter Wire with a plot connector* 80 m / 260 ft (100 pcs.
Base Station Stakes (x4) Wire Connectors [X2] For fixing the Base Station to the ground For splicing the Perimeter Wire in case of a cut Manual Printed Instruction Material Plot Connectors [X2] For connecting the Perimeter Wire to the Base Station RoboRuler For measuring the Perimeter Wire’s distance from the lawn’s edge RoboTool For blades replacement and servicing. IMPORTANT! Keep this tool for future use. Ready? Let’s begin...
Get started Choosing the Base Station location The Base Station is where Robomow recharges, and where the Perimeter Wire starts and ends. In this installation step, you are going to determine a proper location for the Base Station.
Follow these simple guidelines to find a proper location for your Base Station Up to 10 meters / 33 feet away from a power outlet Max 10 m / 33 ft Base Station A min. of 1 meter / 3.3 feet straight wire before the base to allow smooth docking Min 1m /3.3ft A minimum of 1 meter / 3.3 feet from a sprinkler head to avoid damaging the mower’s internal components Min 1 m / 3.3 ft Even and flat (up to +/-5% slope) The Base Station will be installed at a later stage, after the Perimeter Wire is in place.
Lay the wire Lay the Perimeter Wire (“virtual boundary”), which defines the working area for Robomow TIPS WHAT YOU’LL NEED • Have your Robomow box nearby. • Be sure to cut your grass with your old mower one last time before you start wiring. This will make inserting pegs easier and help ensure Robomow doesn’t cut the wire. Hammer Combination pliers Cutter A. Make a good start Use the RoboRuler to determine a distance, which you should keep between the Perimeter Wire and the lawn’s edge.
1 Measure RoboRuler distance III from the corner, where you intend to install the Base Station and mark this point on the ground. 2 Pull out the wire marked A from the Perimeter Wire spool; leave a tail of approx. 20 cm / 8”; once a tail is made, put the first peg into the ground to secure this wire end. 3 20 Drive pegs at two additional locations: at RoboRuler distance I along the edge from the first peg, and at RoboRuler distance III from the edge as shown in the picture.
TIP If your lawn has a corner with a relatively flat edge, you can move the beginning of the wire up to 60 cm / 2 ft outside the lawn. This will define how far off the lawn the Base Station will be installed. Well done! This was the most complex part of the wire installation.
B. Keep proper distances 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. Use the RoboRuler to determine the distance, which you should keep between the Perimeter Wire and lawn’s edge. When the edge is a wall, use also distance III of the RoboRuler. If the edge is relatively flat, lay the wire at RoboRuler distance II from it.
Leave a minimum of 1.2 m (4 ft) if the edge of the lawn borders water. Min 1.2m (4ft) • The Perimeter Wire is secured to the ground by the pegs supplied with Robomow. • 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 Robomow.
C. 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. Robomow 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. Set the Perimeter Wire CLOCKWISE around the obstacle, otherwise Robomow will drive into the Perimeter Island or won’t be able to mow the area around it properly. D.
E. Complete wire setup • Arrive back to the base location until the two wire ends meet each other • Make sure to keep at least 1.
• 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 • Make both wire end the same length a b • Do not leave or create wire wraps 26 c
3 Set base • Place the Base Station in its planned location • Align it to the lawn’s edge • Use RoboRuler distance I to confirm that the center of the Base Station is properly shifted right relative to the wire, as shown in the picture • Fix the base to the ground with the 4 supplied metal stakes Be careful not to damage irrigtion pipes when hammering down the stakes.
Power up 1. Connect the wire tail marked A to the A terminal and the other tail to the B terminal of the Base Station head. 2. Connect the power supply connector to the Base Station head as well. 3. Note the markings for placing the Base Station Head.
4. Place the head on the Base Station and align it with the markings as shown in the picture below. 5. Slide the head all the way through. Pay attention to the sliders and a dedicated slot for threading the wires.
TIP If for some reason you need to remove the base station head, you can do so by lifting the lever (A) and pushing it towards the inside of the base. 6. Plug in the power supply into a socket. Take the power cord out of the mowing area (to prevent Robomow from damaging it) and secure the cord firmly to the ground (so that it does not become a tripping hazard).
GO! • Place Robomow in the center of your lawn • Press GO for 2 seconds to switch it on • Now press the STOP / once to send Robomow to the Base Station. 2 sec • Robomow will start driving* towards the edge of the lawn to locate the Perimeter Wire. Once on it, Robomow will follow the wire to reach the Base Station and park there for charging.
Appendix A Additional installation options 1. On-wire with a flat edge. 2. On-wire with a drop edge.
Appendix B – Secondary areas Connected secondary areas If your lawn has additional areas connected with a passage and Robomow is able to drive through it, then you should bear in mind the following rules: • The minimal distance between the wires in such passage should be 15 cm / 6” • The minimal width of such passage should be 57 cm / 22” Min 15 cm Min 57 cm Separated secondary areas If your lawn has areas, that are completely separated (by a fence, sidewalk, pathway, etc.
Well Done! Now relax, and let Robomow do the work.
