damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Damaged FIG. 1 A battery packs should be returned to service center for recycling. CAUTION: When not in use, place tool on its side on a stable surface where it will not cause a tripping or falling hazard. Some tools with large battery packs will stand upright on the battery pack but may be easily knocked over. 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. 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. The RBRC™ Seal The RBRC™ (Rechargeable Battery Recycling Corporation) Seal on the lithium ion battery (or battery pack) indicates that the costs to recycle the battery (or battery pack) at the end of its useful life have already been paid by DEWALT. RBRC™ in cooperation with DEWALT and other battery users, has established programs in the United States to facilitate the collection of spent lithium ion batteries. Help protect our environment and conserve natural resources by returning the spent lithium ion battery 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. FIG. 3 RBRC™ is a registered trademark of the Rechargeable Battery Recycling Corporation. Storage Recommendations F 1. The best storage place is one that is cool and dry away from direct sunlight and excess heat or cold. 2. Long storage will not harm the battery pack or charger. Under proper conditions, they can be stored for 5 years or more. Charger Your battery pack requires a 1 hour DEWALT charger. Be sure to read all safety instructions before using your charger. Consult the chart on the back of this manual for compatibility of chargers and battery packs. Charging Procedure 1. Plug the charger into an appropriate outlet before inserting the battery pack. 2. Insert the battery pack into the charger. The charger is equipped with a three-light fuel gauge that will blink according to the state of charge of the battery pack. 3. The completion of charge is indicated by the three red lights remaining ON continuously. The pack is fully charged and may be used at this time or left on the charger.

Problems are indicated by the three red lights flashing together in different patterns. PROBLEM POWERLINE When the charger is used with some portable power sources such as generators or sources that convert DC to AC, the charger may temporarily suspend operation. The three red lights will flash together with two fast blinks followed by a pause. This indicates that the power souce is out of limits. BAD BATTERY The charger can detect a weak or damaged battery. The three red lights will flash together with rapid blinking. The battery will no longer charge and should be returned to a service center or a collection site for recycling. BAD CHARGER The charger will detect if it is not functioning properly. The three red lights will flash together with one fast blink followed by a long blink. The charger will no longer work and should be returned to an authorized service center or replaced. LEAVING THE BATTERY IN THE CHARGER The charger and battery pack can be left connected with the red lights glowing indefinitely. The charger will keep the battery pack fresh and fully charged. This charger features an automatic tune-up mode which equals or balances the individual cells in the battery pack to allow it to function at peak capacity. Battery packs should be tuned up weekly or whenever the battery no longer delivers the same amount of work. To use the automatic tune-up mode, place the battery pack in the charger and leave it for at least 8 hours. Important Charging Notes 1. Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65°F and 75°F (18°- 24°C). DO NOT charge the battery pack in an air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is important and will prevent serious damage to the battery pack. 2. The charger and battery pack may become warm to touch while charging. This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed, or an uninsulated trailer. 3. If the battery pack does not charge properly: a. Check current at receptacle by plugging in a lamp or other appliance b. Check to see if receptacle is connected to a light switch which turns power off when you turn out the lights. c. Move charger and battery pack to a location where the surrounding air temperature is approximately 65°F - 75°F (18°- 24°C). d. If charging problems persist, take the tool, battery pack and charger to your local service center. 4. The battery pack should be recharged when it fails to produce sufficient power on jobs which were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the charging procedure. You may also charge a partially used pack whenever you desire with no adverse affect on the battery pack. 5. 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. 6. Do not freeze or immerse charger in water or any other liquid. WARNING: Shock hazard. Do not allow any liquid to get inside charger. CAUTION: Never attempt to open the battery pack for any reason. If the plastic housing of the battery pack breaks or cracks, return to a service center for recycling. COMPONENTS (Fig. 1, 3) WARNING: Never modify the power tool or any part of it.
