Use only for charging geometrically 
matching STIHL batteries with a 
maximum capacity of 50 Ah and a 
maximum voltage of 42 V.
WARNING
Never charge defective, damaged, 
cracked, deformed or leaking batteries.
To reduce the risk of shock and/or fire, 
connect the charger only to a power 
supply with the voltage and frequency 
specified on the rating plate. Always 
plug the charger into a properly installed 
wall outlet. Do not use an extension cord 
unless absolutely neccessary (see 
below).
WARNING
Never insert a wet battery into the 
charger. Such a battery could cause the 
charger to short circuit.
Operate charger at temperatures 
between 41 °F (5 °C) and 104 °F 
(40 °C).
Allow the charger to cool down normally 
– do not cover it.
Never bridge the contacts of the charger 
with metallic objects (e.g. nails, coins, 
jewelry) – short circuit. The charger will 
be damaged by a short circuit.
In the event of smoke or fire in the 
charger, disconnect it from outlet 
immediately.
WARNING
To reduce the risk of electric shock or 
short circuit, do not insert any objects 
into the charger's cooling slots.
WARNING
The charger heats up during the 
charging process. Do not operate on an 
easily combustible surface (e.g. paper, 
cardboard, textiles) or in an easily 
combustible environment – risk of fire.
WARNING
Do not operate in a hazardous location, 
i.e. in a location where there are 
combustible liquids (fumes), vapors or 
dusts. Chargers can produce sparks, 
which may ignite the dust or vapors – 
risk of explosion.
Never use a charger with damaged 
housing. Do not operate the charger if it 
has received a sharp blow, been 
dropped or otherwise damaged in any 
way.
Never jerk the power supply cord to 
disconnect it from the wall outlet. To 
unplug, grasp the plug, not the cord. 
Have a damaged power supply cord 
repaired by an experienced electrician.
Do not use the power supply cord for 
any other purpose, e.g. for carrying or 
hanging up the charger.
Never use power supply cords that do 
not comply with regulations.
Make sure the power supply cord is 
located and/or marked so that it will not 
be stepped on, tripped over, come in 
contact with sharp edges or moving 
parts or otherwise be subjected to 
damage or stress.
WARNING
To reduce the risk of shock and/or 
overheating and fire, an extension cord 
should not be used unless absolutely 
necessary. If an extension cord must be 
used, plug the charger into a properly 
wired 16 gauge (AWG 16) or heavier 
gauge extension cord with blades that 
are the same number, size and shapes 
as the blades on the charger.
Protect the charger from 
rain and dampness. Keep 
charger dry.
Use and store charger 
only indoors in dry rooms.
Check the charger's 
power supply cord and 
plug regularly for dam-
age. If the power supply 
cord or plug is damaged, 
immediately disconnect 
the plug from the wall 
outlet to avoid the risk of 
electric shock.
