4.6.4 Example 2
The times used in this example are applicable to
SILENO city, smart SILENO city (500 m
2
), but the
principle is the same for the other models.
Schedule setting Period 1 (A): 08:00 - 17:00.
Schedule setting Period 2 (C): 20:00 - 23:00.
Active period (A): 08:00 - 17:00
Active period (C): 20:00 - 22:00.
The robotic lawnmower will operate between 08:00 and
17:00. It will begin again at 20:00 but stops running at
22:00 due to standby mode until it starts again at 08:00.

4.7 Charge a flat battery
When the GARDENA robotic lawnmower is new or has
been stored for a long period, the battery will be flat and
needs to be charged before starting.
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.
1. Press the ON/OFF button to start the robotic
lawnmower.
2. Place the robotic lawnmower in the charging station.
Slide the robotic lawnmower in as far as possible to
ensure proper contact between the robotic
lawnmower and the charging station. See contact
and charging strips in
Product overview on page 5
3. The display shows a message that charging is in
progress.
4.8 Adjust the cutting height
The cutting height can be varied from MIN (2 cm) to
MAX (5 cm).
CAUTION: During the first weeks after a new
installation, the cutting height must be set to
MAX to avoid damaging the loop wire. After this,
the cutting height can be lowered step by step
every week until the desired cutting height has
been reached.
4.8.1 To adjust the cutting height
1. Press the STOP button to stop the robotic
lawnmower.
2. Open the hatch.
3. Turn the knob to the required position.
• Turn clockwise to increase the cutting height.
• Turn counter-clockwise to decrease the cutting
height.
4. Close the hatch.
