Do you have a question about the AMBROGIO L250 Deluxe and is the answer not in the manual?

This document describes a robotic lawnmower, specifically models 7250DE0, 7250EL0, and 8250ES0, designed for automatic lawn maintenance.

Function Description

The robotic lawnmower is designed to autonomously cut grass in gardens and house lawns at any time of the day or night. It operates by following a perimeter wire that defines the working area. The robot is programmed to work in more than one area, including primary and secondary areas, and can be set to follow a specific cutting schedule. It automatically returns to the charging station when its battery is low or when its work cycle is complete. The robot can be programmed to optimize mowing in areas with irregular shapes or obstacles. It features a "Re-entry" method for quick re-entry to the charging station and a "Follow wire" method for following the perimeter wire. The robot can also be used in "closed areas" without a charging station for specific tasks.

Usage Features

The robot is designed for ease of use and programming. Initial setup involves placing the robot in the charging station, pressing the ON/OFF power button, reading safety information, setting the desired language, date, and time. The robot can be programmed with a work schedule, setting the number of working areas (up to 8), and defining their dimensions and directions. It supports various mowing patterns, including spiral and random. The robot's cutting height is adjustable. It features a control panel with icons indicating GPS status, Bluetooth status, GPRS receiver status, battery charge level, and robot information. The robot can be set to "Work" (immediate start), "Pause" (suspend automatic programming), or "Settings" (program the robot). It also includes a "Re-entry" function for quick return to the charging station and a "Rain sensor" that can be set to "ON," "DELAY," or "OFF." The robot can operate in "closed areas" without a charging station for specific tasks. The user can access a menu to set installation and operating parameters, including PIN code, connectivity, language, time, sound alerts, and factory reset.

Maintenance Features

Regular maintenance is crucial for the robot's longevity and performance. The manual provides a scheduled maintenance table:

Weekly:
- Blade: Clean and check the efficiency of the blade. If the blade is bent or very worn, replace it.
- Battery charging knobs: Clean and remove any rust.
- Contact plates: Clean and remove any rust.
- Rain sensor: Clean and remove any rust.
Monthly:
- Robot: Clean the robot.
Once a year and at the end of the mowing season:
- Robot: Have the robot serviced at an authorised service centre.

Robot Cleaning: The robot should be cleaned regularly. Use protective gloves. Clean all outside surfaces with a sponge soaked in warm water and a mild detergent. Do not use solvents or benzene. Do not wash inside parts or use jets of pressurized water. Check the lower part of the robot (cutting blade area, and wheels), use a brush suitable to remove deposits and/or residues. Remove any grass and leaves from the gripping areas of the robot. Clean the knobs of the battery charger and remove any deposits or residuals. Clean the rain sensor. Clean the inside of the charging station.

Part Replacement: Recommendations for replacing parts include replacing batteries at an authorised service centre and replacing the blade. To replace the blade, stop the robot, remove the hood, unscrew the screws, remove the old blade, insert a new blade, and fasten the screws.

Robot Disposal: The robot is classified as WEEE (waste electrical and electronic equipment) and should not be disposed of as normal domestic waste. It must be recycled in compliance with local laws. Batteries contain harmful substances and must be disposed of in suitable containers or at authorised waste disposal centres. Packaging materials are recyclable.
