.
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.

tip screwdriver.
4. Remove each blade and screw.
5. Fasten new blades and screws.
6. Check that the blades can pivot freely.
5.4 Battery
The battery is maintenance-free, but has a limited
service life of 2 to 4 years.
Battery service life is dependent on the length of the
season and how many hours a day the robotic
lawnmower is used. A long season or many hours of use
per day means that the battery must be replaced more
regularly.
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.
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.
If the operating times for the robotic lawnmower are
shorter than normal between charges, this indicates that
the battery is getting old and eventually needs replacing.
The battery is fine as long as the robotic lawnmower
maintains a well-cut lawn.
