English the battery pack in an air temperature below +40 °F (+4.5 °C), or above +104 °F (+40 °C). This is important and will prevent serious damage to the battery pack. 2. The charger and battery pack may become warm to the 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 operation of 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 the 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 effect on the battery pack. 5. 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 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. 6. Do not freeze or immerse the charger in water or any other liquid. Storage Recommendations 1. The best storage place is one that is cool and dry, away from direct sunlight and excess heat or cold. 2. For long storage, it is recommended to store a fully charged battery pack in a cool dry place out of the charger for optimal results. NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will need to be recharged before use. SAVE THESE INSTRUCTIONS FOR FUTURE USE COMPONENTS (FIG. A) WARNING: Never modify the power tool or any part of it. Damage or personal injury could result. Refer to Figure A at the beginning of this manual for a complete list of components. Intended Use This impact wrench is designed for professional impact fastening and drilling applications. The impact function makes this tool particularly useful for driving fasteners in wood, metal and concrete. DO NOT use under wet conditions or in presence of flammable liquids or gases. This impact wrench is a professional power tool. DO NOT let children come into contact with the tool. Supervision is required when inexperienced operators use this tool. NOTE: To get the maximum performance from your impact wrench, use a DeWALT Flexvolt™ or 20V Max* battery with 4.0 Ah or higher. Variable Speed Trigger Switch (Fig. A) To turn the tool on, squeeze the trigger switch 1 . To turn the tool off, release the trigger switch. Your tool is equipped with a brake. The anvil will stop when the trigger switch is fully released. The variable speed switch enables you to select the best speed for a particular application. The more you squeeze the trigger, the faster the tool will operate. For maximum tool life, use variable speed only for starting holes or fasteners. NOTE: Continuous use in variable speed range is not recommended. It may damage the switch and should be avoided. Forward/Reverse Control Button (Fig. A) A forward/reverse control button 2 determines the direction of the tool and also serves as a lock-off button. To select forward rotation, release the trigger switch and depress the forward/reverse control button on the right side of the tool. To select reverse, release the trigger switch and depress the forward/reverse control button on the left side of the tool. The center position of the control button locks the tool in the off position. When changing the position of the control button, be sure the trigger is released. NOTE: The first time the tool is run after changing the direction of rotation, you may hear a click on start up. This is normal and does not indicate a problem. Worklight (Fig. A) There is a worklight 7 located on the foot of the tool. The worklight is activated when the trigger switch is depressed, and will automatically turn off 20 seconds after the trigger switch is released. If the trigger switch remains depressed, the worklight will remain on. NOTE: The worklight is for lighting the immediate work surface and is not intended to be used as a flashlight. Mode Selector (Fig. A, D) Your tool is equipped with a mode selector 8 which allows you to select one of two speeds or the Precision Wrench™ mode. Select the speed/mode based on the application and control the speed of the tool using the variable speed trigger switch 1 . 8
