5.3 Replace the blades WARNING: Use blades and screws of the right type. Husqvarna can only guarantee safety when using original blades. Only replacing the blades and reusing the screw can result in a screw wearing during mowing. The blades can then be propelled from under the body and cause serious injury. Replace worn or damaged parts for safety reasons. Even if the blades are intact, they should be replaced on a regular basis for the best mowing result and low energy usage. All 3 blades and screws must be replaced at the same time to obtain a balanced cutting system. Use Husqvarna original blades embossed with the crowned H-mark logotype, refer to Technical data on page 38. 7. Attach 3 new blades and screws. 8. Make sure that the blades can pivot freely. 5.4 Battery WARNING: Only charge the product 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. WARNING: Use only original batteries recommended by the manufacturer. Product safety cannot be guaranteed with other batteries. Do not use non-rechargeable batteries. 5.3.1 To replace the blades 1. Push the STOP button 2. Set the Main switch to position 0. CAUTION: The battery must charge a complete cycle before winter storage. If the battery is not fully charged it can be damaged and in certain cases be rendered useless. If the operating time for the product is shorter than normal between charges, this indicates that the battery is getting old and eventually needs replacing. Note: Battery life is dependent on the length of the season and how many hours a day the product is operating. A long season or many hours of use a day means that the battery must be replaced more regularly. The battery is fine as long as the product maintains a well-cut lawn. 3. Turn the product upside down. Put the product on a soft and clean surface to avoid scratching the product. 4. Rotate the skid plate so that its holes align with the screws for the blade. 5. Remove the 3 screws with a screwdriver. 6. Remove the 3 blades. 5.5 Winter service Take your product to your Husqvarna central service for service prior to winter storage.
