IMPORTANT SAFETY INFORMATION

WARNING

Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference.
The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

1. The battery Charger gets hot during use. The Charger’s heat can build up to unsafe levels and create a fire hazard if it does not receive adequate ventilation, due to an electrical fault, or if it is used in a hot environment. Do not place the Charger on a flammable surface. Do not obstruct any vents on the Charger. Especially avoid placing the Charger on carpets and rugs; they are not only flammable, but they also obstruct vents under the Charger. Place the Charger on a stable, solid, nonflammable surface (such as a stable metal workbench or concrete floor) at least 1 foot away from all flammable objects, such as drapes or walls. Keep a fire extinguisher and a smoke detector in the area. Frequently monitor the Charger and Battery Pack while charging.
2. Charge only designated battery packs; others may overheat, leak, or burst.
3. Follow charging instructions.
4. Do not insert damaged battery pack.
5. Check frequently while charging.
6. Wear ANSI-approved safety goggles during use.
7. Use chargers only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
8. When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery pack terminals together may cause burns or a fire.
9. Under abusive conditions, liquid may be ejected from the battery pack; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery pack may cause irritation or burns.
10. Do not expose to rain or wet conditions. Indoor use only.
11. Inspect before every use; do not use if parts are loose or damaged.
12. Use as intended only.
13. Unplug after use and before service, cleaning or storage.
14. Maintain labels and nameplates on the Charger. These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
15. This product is not a toy. Keep it out of reach of children.
16. People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure. In addition, people with pacemakers should properly maintain and inspect to avoid electrical shock.

• Open,
• Drop,
• Short-circuit,
• Puncture,
• Incinerate, or
• Expose to temperatures greater than 140°F.

1. Store batteries in a dry, indoor area at room temperature out of reach of children and away from metal objects (i.e., paperclips, coins) to prevent shorting.
2. NOTICE : Battery may be damaged if stored at high temperatures (over 120° F).
3. Recharge the Battery Pack at least once a year.
