5 IMPORTANT SAFETY INSTRUCTIONS
– In case of doubt, have the robotic mower checked by 
your authorized STIHL iMow servicing dealer before 
using it.
■ If the robotic mower is damaged, not working properly or 
has been immersed in water or other liquids, its 
components, including its integrated battery, may no 
longer function properly and safety devices may be 
inoperative. To reduce the risk of personal injury and 
property damage:
– Take the robotic mower to your authorized STIHL 
iMow servicing dealer to be checked before further 
use.
■ Genuine STIHL replacement parts are specifically 
designed to match your robotic mower and meet safety 
and performance requirements. Use of parts that are not 
authorized or approved by STIHL may cause serious or 
fatal injury or property damage.
– STIHL recommends that only identical STIHL 
replacement parts be used.
5.5 Integrated Battery
WARNING
■ Use of an unauthorized charging device can damage the 
lithium ion battery inside the robotic mower and result in 
fire, explosion and personal injury and property damage.
– Charge the robotic mower only with a genuine 
STIHL ADO 401 docking station and OWA-60U-
27VUSM power supply.
■ The robotic mower's integrated battery contains safety 
features and devices which, if damaged, may allow it to 
generate heat, rupture, leak, ignite or explode.
– Be alert for signs that the battery may be damaged: 
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.
– The battery is integrated into the robotic mower and 
should not be removed by the operator. Have the 
integrated battery removed by an authorized STIHL 
iMow servicing dealer when the battery is depleted 
or the mower reaches the end of its useful life. Never 
attempt to remove the battery or open or 
disassemble the robotic mower's hood for any 
reason.
– Never subject the robotic mower to heavy impacts or 
attempt to crush, drop or otherwise damage it.
– Never expose the robotic mower to microwaves or 
high pressures.
– Never insert foreign objects into the robotic mower's 
charging socket or other openings. 
■ High temperatures may cause the robotic mower's 
integrated battery to generate heat, rupture, leak, ignite or 
explode, resulting in severe or fatal personal injury and 
property damage. Exposure to temperatures outside the 
recommended temperature range may also damage the 
battery and reduce its useful life.
– Never heat the robotic mower above 
212 °F (100 °C) or place it on or near 
fires, stoves or other high-temperature 
locations.
– Use the robotic mower only within an 
ambient temperature range of 41 °F to 
104 °F (5 °C to 40 °C).
– Store the robotic mower only within an 
ambient temperature range of 32 °F to 
122 °F  (0 °C to 50 °C).
– Never store the robotic mower inside a 
vehicle in hot weather.
