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 1-hour 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. 4. Once the Automatic Tune Up mode is complete, the charger will begin a maintenance charge; the red indicator will remain lit. SAVE THESE INSTRUCTIONS FOR FUTURE USE Chargers Your tool uses a DEWALT Charger. Your battery can be charged in DEWALT 1 Hour Chargers, 15 Minute Chargers or Vehicular 12 volt charger. Be sure to read all safety instructions before using your charger. Consult the chart on the back cover of this manual for compatibility of chargers and battery packs. FIG. 2 15 MINUTE CHARGER 1 HOUR CHARGER Charging Procedure DANGER: Electrocution hazard. 120 volts are present at charging terminals. Do not probe with conductive objects. 1. Plug the charger into an appropriate outlet before inserting battery pack. 2. Insert the battery pack into the charger. The red (charging) light will blink continuously indicating that the charging process has started (Fig. 2). 3. The completion of charge will be indicated by the red light remaining ON continuously. The pack is fully charged and may be used at this time or left in the charger. Indicator Light Operation Charge Indicators Some chargers are designed to detect certain problems that can arise with battery packs. Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert battery pack into the charger. If the problem persists, try a different battery pack to determine if the charger is OK. If the new pack charges correctly, then the original pack is defective and should be returned to a service center or 6 other collection site for recycling. If the new battery pack elicits the same trouble indication as the original, have the charger tested at an authorized service center. HOT/COLD PACK DELAY Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a battery that is hot, it automatically starts a Hot Pack Delay, suspending charging until the battery has cooled. After the battery has cooled, the charger automatically switches to the Pack Charging mode. This feature ensures maximum battery life. The red light flashes long, then short while in the Hot Pack Delay mode. PROBLEM POWER LINE Some chargers have a Problem Power Line indicator. 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, flashing the red light with two fast blinks followed by a pause. This indicates the power source is out of limits. LEAVING THE BATTERY PACK IN THE CHARGER The charger and battery pack can be left connected with the red light glowing indefinitely. The charger will keep the battery pack fresh and fully charged. NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the battery pack has not been kept on maintenance charge, it may need to be recharged before use. A battery pack may also slowly lose its charge if left in a charger that is not plugged into an appropriate AC source. WEAK BATTERY PACKS: Chargers can also detect a weak battery. Such batteries are still usable but should not be expected to perform as much work. In such cases, about 10 seconds after battery insertion, the charger will beep rapidly 8 times to indicate a weak battery condition. The charger will then go on to charge the battery to the highest capacity possible. 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. 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.
