6 Docking Station and Power Supply Safety
6.2 Warnings and Instructions
WARNING
■ To reduce the risk of fire, electric shock and other
personal injury or property damage:
– Read and follow all cautionary markings on the
docking station, power supply and robotic mower
and all instructions in this manual before using the
docking station.
– Use the ADO 401 docking station and OWA-60U-
27VUSM power supply only for charging the
STIHL RMI 422 P robotic mower. Using the docking
station or power supply for other purposes is
prohibited and may lead to fire, explosion or electric
shock, resulting in serious or fatal personal injury
and property damage.
– Never use a damaged or improperly functioning
docking station or power supply.
– Never use or charge a robotic mower if the hood or
housing is cracked, deformed or excessively hot, if
battery fluid is leaking from the battery compartment,
or if the battery is otherwise damaged. A damaged
battery increases the risk of personal injury and
property damage from short circuit, fire or explosion.
– Connect the power supply cord only to a properly
covered Class A Ground Fault Circuit Interruptor
(GFCI) receptacle that has an enclosure that is
weatherproof with an attachment plug cap inserted
or removed. Do not use with receptacles that are
weatherproof only when the receptacle is covered
(attachment plug cap not inserted and receptacle
cover closed).
– Never plug the docking station into a power strip or
an extension cord.
– Do not operate a docking station or power supply
that has received a sharp or heavy blow, has been
dropped or is otherwise damaged or not functioning
properly in any way.
– Do not attempt to repair, open or disassemble the
docking station or power supply. There are no user-
serviceable parts inside.
■ The docking station and power supply heat up during the
charging process. To reduce the risk of fire:
– Use the docking station and power supply only within
an ambient temperature range of 32 °F to 122 °F
(0 °C to 50 °C).
– Do not operate the docking station on a combustible
surface (e.g., paper, cardboard, textiles) or in a
combustible environment.
– Allow the docking station and power supply to cool
down normally. Do not cover them.
■ The docking station can produce sparks which may ignite
combustible gases, liquids, vapors, dusts or other
combustible materials. To reduce the risk of fire and
explosion:
– Do not operate in a location where combustible
gases, liquids, vapors, dusts or other combustible
materials are present.
■ Using a damaged power supply cord or plug may result in
fire, electric shock and other serious personal injury or
property damage. To reduce these risks:
– Unplug the power supply from the electrical outlet
when the docking station is not in use.
– Never jerk the power supply cord to disconnect it
from the electrical outlet. To unplug, grasp the plug,
not the power supply cord.
– Do not use the power supply cord for any other
purpose, e.g., for carrying or hanging up the power
supply.
– Make sure the power supply cord is located or
marked so that it will not be stepped on, tripped over,
come in contact with sharp objects or moving parts,
or otherwise be subjected to damage or stress.
– Check the power supply cord and plug
before use and regularly thereafter for
damage. If damaged, immediately
disconnect from the electrical outlet.
