• An extension cord should not be used with any battery charger unless abso-
lutely necessary. Use of an improper extension cord could result in a risk of
fire and electric shock. If an extension cord must be used, make sure that:
• The pins on the plug of the extension cord are the same number, size,
and shape as those on the plug of the charger.
• The extension cord is properly wired and in good electrical condition.
• The cord size is 18AWG for lengths up to 100 feet and 16AWG for
lengths up to 150 feet.
• To reduce the risk of injury, charge only the rechargeable batteries
listed in the Accessories section of this manual. Other types of batter-
ies may burst, causing personal injury and damage.
