Dewalt DHS790AT2 Instruction Manual - Page 8

English • 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 the charger to rain or snow. • Pull by the plug rather than the cord when disconnecting the charger. This will reduce the risk of damage to the electric plug and cord. • Make sure that the 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. • When operating a charger outdoors, always provide a dry location and use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. • 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. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord. Minimum Gauge for Cord Sets Volts Total Length of Cord in Feet (meters) Ampere Rating 120V 25 (7.6) 50 (15.2) 100 (30.5) 150 (45.7) 240V 50 (15.2) 100 (30.5) 200 (61.0) 300 (91.4) More Than Not More Than AWG 0 6 18 16 16 14 6 10 18 16 14 12 10 12 16 16 14 12 12 16 14 12 Not Recommended • Do not place any object on top of the 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 the charger with a damaged cord or plug. • Do not operate the 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 the 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 120V household electrical power. Do not attempt to use it on any other voltage. This does not apply to the vehicular charger. WARNING: Shock hazard. Do not allow any liquid to get inside the charger. Electric shock may result. WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any liquid to enter the battery pack. 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. CAUTION: Burn hazard. To reduce the risk of injury, charge only DeWALT rechargeable battery packs. Other types of batteries may overheat and burst resulting in personal injury and property damage. NOTICE: Under certain conditions, with the charger plugged into the power supply, the charger can be shorted by foreign material. Foreign materials of a conductive nature, such as, but not limited to, grinding dust, metal chips, steel wool, aluminum foil or any buildup of metallic particles should be kept away from the charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug the charger before attempting to clean. Charging a Battery (Fig. 3) Plug the charger into an appropriate outlet before inserting battery pack. FIG. 3 Insert the battery pack into the charger, making sure the battery pack is fully seated in the charger. The red (charging) light will blink continuously indicating that the charging process has started. The completion of charge will be indicated by the red light remaining ON continuously. The battery pack is fully charged and may be used at this time or left in the charger. To remove the battery pack from the charger, push the battery release button on the battery pack. NOTE: To ensure maximum performance and life of lithium-ion battery packs, charge the battery pack fully before first use. CHARGER OPERATION Refer to the indicators below for the charge status of the battery pack. DCB107, DCB112, DCB113, DCB115, DCB118, DCB132 Charging Fully Charged Hot/Cold Pack Delay* *T he red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack has reached an appropriate temperature, the yellow light will turn off and the charger will resume the charging procedure. The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery pack by refusing to light or by displaying a problem pack or charger blink pattern. 6
