644429-00,DC612 7/10/06 11:56 AM Page 3 English does not indicate a failure. However, if the outer seal is broken and this leakage gets on your skin: a. Wash quickly with soap and water. b. Neutralize with a mild acid such as lemon juice or vinegar. c. If battery liquid gets into your eyes, flush them with clean water for a minimum of 10 minutes and seek immediate medical attention. (Medical note: The liquid is 25-35% solution of potassium hydroxide.) • Charge the battery packs only in DEWALT chargers. • DO NOT splash or immerse in water or other liquids. • Do not store or use the tool and battery pack in locations where the temperature may reach or exceed 105°F (such as outside sheds or metal buildings in summer). DANGER: Electrocution hazard. Never attempt to open the battery pack for any reason. If battery pack case is cracked or damaged, do not insert into charger. Electric shock or electrocution may result. Damaged battery packs should be returned to service center for recycling. NOTE: Battery storage and carrying caps are provided for use whenever the battery is out of the tool or charger. Remove cap before placing battery in charger or tool. WARNING: Fire hazard. Do not store or carry battery so that metal objects can contact exposed battery terminals. For example, do not place battery in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, etc. without battery cap. Transporting batteries can possibly cause fires if the battery terminals inadvertently come in contact with conductive materials such as keys, coins, hand tools and the like. The US Department of Transportation Hazardous Material Regulations (HMR) actually prohibit transporting batteries in commerce or on airplanes (i.e., packed in suitcases and carry-on luggage) UNLESS they are properly protected from short circuits. So when transporting individual batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit. CAUTION: Battery pack must be securely attached to tool. If battery pack is detached, personal injury may result. The RBRC™ Seal The RBRC™ (Rechargeable Battery Recycling Corporation) Seal on the nickel cadmium and nickel metal hydride batteries (or battery packs) indicate that the costs to recycle these batteries (or battery packs) at the end of their useful life have already been paid by DEWALT. In some areas, it is illegal to place spent nickel cadmium and nickel metal hydride batteries in the trash or municipal solid waste stream and the RBRC program provides an environmentally conscious alternative. RBRC™ in cooperation with DEWALT and other battery users, has established programs in the United States and Canada to facilitate the collection of spent nickel cadmium and nickel metal hydride batteries. Help protect our environment and conserve natural resources by returning the spent nickel cadmium and nickel metal hydride batteries to an authorized DEWALT service center or to your local retailer for recycling. You may also contact your local recycling center for information on where to drop off the spent battery. RBRC™ is a registered trademark of the Rechargeable Battery Recycling Corporation. Important Safety Instructions for Battery Chargers SAVE THESE INSTRUCTIONS: This manual contains important safety instructions for battery chargers. • Before using charger, read all instructions and cautionary markings on charger, battery pack, and product using battery pack. DANGER: Electrocution hazard. 120 volts are present at charging terminals. Do not probe with conductive objects. WARNING: Shock hazard. Do not allow any liquid to get inside charger. CAUTION: Burn hazard. To reduce the risk of injury, charge only DEWALT rechargeable batteries. Other types of batteries may burst causing personal injury and damage. CAUTION: Under certain conditions, with the charger plugged in to the power supply, the exposed charging contacts inside the charger can be shorted by foreign material. Foreign materials of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug charger before attempting to clean. • DO NOT attempt to charge the battery pack with any chargers other than the ones in this manual. The charger and battery pack are specifically designed to work together. • These chargers are not intended for any uses other than charging DEWALT rechargeable batteries. Any other uses may result in risk of fire, electric shock or electrocution. • Do not expose charger to rain or snow. • Pull by plug rather than cord when disconnecting charger. This will reduce risk of damage to electric plug and cord. • Make sure that cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress. • Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of fire, electric shock, or electrocution. • An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is 16 gauge has more capacity than 18 gauge. When using more than one extension to make up 3 the total length, be sure each individual extension contains at least the minimum wire size. Recommended Minimum Wire Size for Extension Cords Total Length of Cord 25 ft. 50 ft. 75 ft. 100 ft. 125 ft. 150 ft. 175 ft. 7.6 m 15.2 m 22.9 m 30.5 m 38.1 m 45.7 m 53.3 m Wire Size AWG 18 18 16 16 14 14 12 • Do not place any object on top of charger or place the charger on a soft surface that might block the ventilation slots and result in excessive internal heat. Place the charger in a position away from any heat source. The charger is ventilated through slots in the top and the bottom of the housing. • Do not operate charger with damaged cord or plug - have them replaced immediately. • Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way. Take it to an authorized service center. • Do not disassemble charger; take it to an authorized service center when service or repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or fire. • Disconnect the charger from the outlet before attempting any cleaning. This will reduce the risk of electric shock. Removing the battery pack will not reduce this risk. • NEVER attempt to connect 2 chargers together. • The charger is designed to operate on standard household electrical power (120 Volts). Do not attempt to use it on any other voltage. This does not apply to the vehicular charger. Using Automatic Tune-Up™ Mode The automatic Tune-Up™ Mode equalizes or balances the individual cells in the battery pack allowing it to function at peak capacity. Battery packs should be tuned up weekly or after 10 charge/discharge cycles or whenever the pack no longer delivers the same amount of work. To use the automatic Tune-Up™, place the battery pack in the charger and leave it for at least 8 hours. The charger will cycle through the following modes. 1. The red light will blink continuously indicating that the 1hour charge cycle has started. 2. When the 1-hour charge cycle is complete, the light will stay on continuously and will no longer blink. This indicates that the pack is fully charged and can be used at this time. 3. If the pack is left in the charger after the initial 1-hour charge, the charger will begin the Automatic Tune-Up mode. This mode continues up to 8 hours or until the individual cells in the battery pack are equalized. The battery pack is ready for use and can be removed at any time during the Tune-Up mode.
