To reduce the risk of short circuit, which could lead to electric shock, fire and explosion, make sure the charger and its components are dry and not damaged; operate the charger indoors at an appropriate ambient temperature. WARNING A typical household electric circuit is between 15 and 20 amps. A single STIHL AL 500 charger draws approximately 4.8 amps. A single AL 300 charger draws approximately 4.4 amps. To reduce the risk of fire from overloading an electrical circuit: ► Ensure the electrical system is rated to withstand the expected electrical draw before charging your battery. ► Charge multiple batteries one at a time or on separate circuits, unless you know your circuit can handle the total expected draw from multiple chargers. WARNING Since the charger heats up during the charging process, do not operate the charger on a combustible surface or in a location where combustible gases, liquids, vapors, dusts or other materials and substances are present. To set up the charger: 4 3 1 2 ► Insert the plug (3) into a properly installed wall outlet (4) matching the voltage and electrical frequency stated on the rating plate on the charger.

Once the LED goes out, the self-test is complete and the charger is ready to charge the battery. ► Position the power supply cord (2) so that it will not be stepped on, tripped over, come in contact with sharp objects or moving parts or otherwise present a tripping hazard or be subjected to damage or stress. 8.2 Charging WARNING STIHL batteries contain safety features and devices which, if damaged, may allow the battery to generate heat, rupture, leak, ignite or explode.
