SYMBOL MEANING WARNING: Failure to obey a safety warning can result in injury to yourself and others. NOTE: Advises you of information or instructions vital to the operation or maintenance of the equipment. BATTERY WARNINGS 1. Battery units do not have to be plugged into an electrical outlet, therefore they are always in operating condition. Be aware of possible hazards when you are not using your battery unit. 2. AVOID UNINTENTIONAL STARTING--Don't carry the unit with your finger on the switch. 3. USE ONLY THE CHARGER PROVIDED WITH YOUR BATTERY UNIT. Do not substitute any other charger. Use of another charger could cause batteries to explode, causing serious injury. 4. DO NOT PLACE BATTERY UNITS OR THEIR BATTERIES NEAR FIRE OR HEAT. They may explode. 5.

Use of improper extension cords could result in risk of fire and electric shock. If an extension cord must be used, make sure: a. The pins on the plug of the extension cord are the same number, size and shape as those of the charger. b. The extension cord is properly wired and in good electrical condition; and c. The wire size is large enough for AC ampere rating of the charger as specified below. PRE-OPERATIONAL SAFETY WARNINGS 1. Read and understand this operator's manual carefully before using this unit.
