Use Husqvarna original blades embossed with the crowned H-mark logotype, see Guarantee terms on page 59. batteries. Do not use non-rechargeable batteries. CAUTION: The battery must be charged fully before winter storage. If the battery is not fully charged it can be damaged and in certain cases be rendered useless. 5.3.1 To replace the blades 1. Set the Main switch to position 0. 2. Turn the robotic lawnmower upside down. Place the robotic lawnmower on a soft and clean surface to avoid scratching the body and the hatch. 3. Rotate the skid plate so that its holes align with the screws for the blade. 4. Remove the 3 screws. Use a straight slot or crosstip screwdriver. 5. Remove each blade and screw. 6. Fasten new blades and screws. 7. Check that the blades can pivot freely. 5.4 Battery The battery is maintenance-free, but has a limited life span of 2 to 4 years. WARNING: Only charge the robotic lawnmower using a charging station which is intended for it. Incorrect use may result in electric shock, overheating or leakage of corrosive liquid from the battery. In the event of leakage of electrolyte flush with water and seek medical help if it comes in contact with the eyes etc. Below indicates that the battery is getting old and eventually needs replacing: • The operating time for the robotic lawnmower is shorter than normal between charges. This leads to more charging cycles than normal, which increases the risk of tracks forming near the charging station. • The robotic lawnmower is found standing out on the lawn with Empty battery message. This indicates that the robotic lawnmower does not have battery capacity enough to find the charging station. The battery is fine as long as the robotic lawnmower maintains a well-cut lawn. Note: Battery life is dependent on the length of the season and how many hours a day the robotic lawnmower is operating. A long season or many hours of use a day means that the battery must be replaced more regularly. Contact your local Husqvarna representative to replace the battery. 5.5 Winter service Take your robotic lawnmower to your local Husqvarna representative for service prior to winter storage. Regular winter service will maintain the robotic lawnmower in good condition and create the best conditions for a new season without any disruptions. Service usually includes the following: • Thorough cleaning of the body, the chassis, the blade disc and all other moving parts. • Testing of the mower's function and components. • Checking and, if required, replacing wear items such as blades and bearings. • Testing the mower's battery capacity as well as a recommendation to replace battery if necessary. • If new software is available, the local Husqvarna representative updates the robotic lawnmower. WARNING: Use only original batteries recommended by the manufacturer. Product safety cannot be guaranteed with other 44 - Maintenance 362 - 002 - 06.02.2018
