7.1 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 
charger, battery and blower and all instructions in 
this manual before using the charger.
– Charge only genuine STIHL AK or STIHL AP series 
batteries. Other batteries may burst, catch fire or 
explode, resulting in personal injury and property 
damage.
– Do not handle the charger, including power supply 
cord and plug, with wet hands.
– Never use a damaged charger.
– Never charge malfunctioning, damaged, cracked, 
leaking or deformed batteries.
– Never store a battery in the charger.
– Operate the charger only indoors, in dry rooms and 
within an ambient temperature range of 41 °F to 
104 °F (5 °C to 40 °C).
– Keep the charger out of the reach of children.
– Always plug the charger into a properly installed 
electrical outlet matching the voltage and electrical 
frequency stated on the charger.
– Never use power strips to operate multiple chargers 
or other devices from the same outlet or on the same 
circuit.
– Do not operate a charger that has received a sharp 
or heavy blow, has been dropped or is otherwise 
damaged in any way.
– Do not attempt to repair, open or disassemble the 
charger. There are no user-serviceable parts inside.
■ To reduce the risk of electric shock or fire from a short 
circuit:
– Make sure the battery and charger are completely 
dry before starting the charging process.
– Never bridge the contacts of the charger with wires 
or other metallic objects.
– Do not insert any objects into the charger’s cooling 
slots.
■ The charger heats up during the charging process. To 
reduce the risk of fire:
– Do not operate on a combustible surface (e.g., 
paper, cardboard, textiles) or in a combustible 
environment.
– Allow the charger to cool down normally. Do not 
cover it.
■ Chargers 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 personal injury or property 
damage. To reduce these risks:
– Have a damaged power supply cord replaced by an 
authorized STIHL servicing dealer.
– Unplug the power supply cord from the outlet when 
the charger is not in use.
