6 Charger Safety
■ To reduce the risk of electric shock or fire from a short 
circuit:
► Make sure the blower and charger are completely dry 
before starting the charging process.
■ 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:
► Replace the charger if the power supply cord becomes 
damaged. The power supply cord cannot be repaired or 
replaced.
► Unplug the charger from the wall outlet when not in use.
► Never jerk the power supply cord to disconnect it from 
the wall 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 charger.
► 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.
■ An extension cord should not be used unless absolutely 
necessary. Overloading an extension cord can result in 
overheating and fire. If an extension cord must be used:
► Use only a properly wired 16 gauge (AWG16) or 
heavier gauge extension cord.
► Never connect more than one charger or other device to 
an extension cord.
► Never use an extension cord with a wattage rating lower 
than the wattage on your charger's rating plate.
► Never use an extension cord if the blades on its plug are 
different from the blades on the charger plug in number, 
size or shape.
► Do not link (chain) extension cords.
■ In case of fire, or if the charger or blower it is charging 
emits smoke, an unusual smell, feels hot or appears 
abnormal in any other way:
► Immediately disconnect the charger from the outlet. 
Contact the authorities in the event of fire or explosion.
► Have the charger and blower inspected and repaired by 
an authorized STIHL servicing dealer before use.
■ Operation of the blower is disabled during the charging 
process to reduce the risk of electric shock.
► Do not attempt to operate the blower during the 
charging process or any time it is connected to the 
LK45.
► Check the charger's power supply cord 
and plug regularly for damage. If 
damaged, immediately disconnect the 
plug from the wall outlet.
