Service Schedule - Husqvarna Automower 420 Technical Manual

The robotic lawnmower must be stored, preferably in
its original packaging, in a dry area, standing on all
wheels.
The mower and the power supply should be stored
inside during the winter. If the power supply is con-
nected to a mains socket indoors and connected to
the charging station, the charging station can be left
outdoors. Otherwise, the charging station must be
stored indoors.
If the charging station is stored indoors it is important
to remember to protect the ends of the boundary wire
from moisture by placing them, for example, in a cou-
pler from Husqvarna.
