Keep the boundary line at least 35cm (14”) away from any: walls, drop-offs, or uneven edge. If the lawn is level with the edge of the grass set the wire 10cm (4”) away from the edge. Do not allow the boundary wire to cross itself. The boundary line should be placed at the root level of the grass (see Figure 1). Secure the boundary line into the ground and anchor with the boundary stakes. Place a stake approximately every 3 feet. greater than 20°. On slopes steeper than 20° the robot’s sensor will shut the mower off. m Planning and Laying the Boundary Line Laying Boundary Lines In order to make the Robot Mower mow within the desired area – and only that area – you need to mark the area by means of boundary wiring. Remove all foreign objects, rocks, roots, etc. that may interfere with the Robot Mower’s operation in the mowing area. Large objects such as trees, swings sets, ponds, etc. should be encircled by the boundary line. The boundary wire line needs to be laid out in a continuous line (see Figure 2 on following page). Docking Station Installation Avoid placing the docking station in a corner of the lawn or in low-lying areas where the docking station or the Robot Mower may be damaged by puddles, or under a high tree due to the risk of lightning. Note: It is important that the adapter and the electrical plug are always kept dry! The docking station must have 6.5 feet of free space in front of it so the Robot Mower can return to charge or when mowing is complete (see Figure 3). The docking station must be located on level ground for correct operation. Connecting the Boundary Line to the Docking Station Remove the terminal cover located on the back of the docking station. Insert the end of the boundary wire into a blue T- clip and use a pair of pilers to press the clip on the wire until you hear a click. Repeat this action on the other end of the wire. Insert the wire that leaves the docking station into the negative (-) metal prong. Connect the wire that comes from under the docking station to the positive (+) metal prong. Proceed to plug in the docking station and confirm the LED is a solid GREEN light. If the LED is flashing RED and GREEN confirm all of your docking station connections are securely inserted and the boundary wire does not have any cuts or breakage. Figure 4 Figure 3 CLICK Operation Operation Operation Operation Sensors Obstacle/Contact Sensor When the Robot Mower meets an obstacle, it will reverse and a new path within 10 seconds, the robot will shut down and it will require a manual restart to continue operation. Rain Sensor In case of heavy rain, the Robot Mower will automatically return to the docking station. It will automatically start mowing the next day at the time originally sheduled. Lift Sensor This sensor is placed close to the wheels and measures the gravity of the wheels. If the Robot Mower is lifted manually or if both wheels run into a hole, the robot will shut down and must be restarted manually. Tilt Sensor A 6-axle sensor is integrated in the Robot Mower to measure the tilt angle in all directions. If the tilt angle exceeds 20°, the cutting motor will stop immediately but continue driving (see Figure 7). If the angle decreases to less than 20° within 10 seconds, the cutting motor will restart automatically. If, however, the angle does not decrease within 10 seconds the mower will shut down and will require a manual restart. Maintenance and Storage Cleaning the Robot Mower Lift the front and rear covers and remove any collected debris, grass clippings and dust using a soft brush, vacuum or damp cloth. Repeat for the bottom side of the robot using care when handling the blade disc and blades. It is important to keep the blades free from accumulated grass clippings to ensure proper operation of the robot mower. Ensure all retaining screws are secure. Clean and brush the contacts on the robot mower and the docking station charging arms with steel wool or emery paper. Cleaning the Docking Station Remove dirt, grass and other debris from the docking station base plate on a regular basis. Blade Replacement The Robot Mower blades are accessible when you turn the mower upside down (see Figure 8). Blades have two edges and two sides. The blades can be turned over one time before replacing. Blade replacement is indicated when grass shows prominent white edges after cutting or the mower makes excessive vibration noise. Turn all three blades over or replace all three blades by unscrewing the three retaining screws. Blade Disc Figure 8 Cutting Blades Maintenance and Storage ! DANGER Blades are extremely sharp and will cut even when dull. Use caution when replacing. Wear gloves to protect hands from cuts. Storage Disconnect the docking station from the AC power adapter. Remove the ends of the boundary wire from the docking station. Turn the power switch off on the Robot Mower to protect the battery. Store the Robot Mower, docking station and AC adapter and cords in a dry frost free area. Cover the ends of the boundary wire with electrical tape. To help preserve the life of the battery, check the charge status of the battery and recharge the battery in the docking station at regular intervals. Winter Storage During winter seasons, please follow all guidelines explained in the Storage Section above. Failure to properly care for your MowRo will void any remaining warranty.
