result in a screw wearing during mowing and
shearing. 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.
There are 3 blades on the robotic lawnmower, which are
screwed into the blade disc. All 3 blades and screws
must be replaced at the same time to obtain a balanced
cutting system.
Use GARDENA original blades embossed with the
crowned H-mark logotype, see
Guarantee terms on
page 53
.
5.3.1 To replace the blades
1. Press the STOP button.
2. Open the hatch.
3. Press the ON/OFF button for 3 seconds to turn off
the robotic lawnmower.
4. Check that the indicator lamp on the ON/OFF button
is not lit.
5. Turn the robotic lawnmower upside down. Place the
robotic lawnmower on a soft and clean surface to
avoid scratching the body and the hatch.
6. Remove the 3 screws. Use a straight slot or cross-
tip screwdriver.
7. Remove each blade and screw.
8. Fasten new blades and screws.
9. Check that the blades can pivot freely.
5.4 Software update
If service is done by GARDENA customer service then
available software updates are downloaded to the
robotic lawnmower by the service technician. However,
owners of GARDENA robotic lawnmowers can update
the software if this is initiated by GARDENA. Registered
users will in that case be notified by email.
5.5 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.
