ENGLISH 4. Hold tool firmly with both hands to control the twisting action of the drill. 5. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL - THIS CAN DAMAGE THE DRILL. 6. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming. Screwdriver Operation (Figure 4) 1. Select the desired speed/torque range using the three-speed gear shifter (g) on the top of tool to match the speed and torque to the planned application. Initially set the torque adjustment collar (e) at a lower setting to ensure the fastener to be set to your specification. NOTE: Use the lowest torque setting required to seat the fastener at the desired depth. The lower the number, the lower the torque output. 2. Rotate the mode control collar (f) so the screw symbol is aligned with the arrow. 3. Reset the torque adjustment collar (e) to the appropriate number setting for the torque desired. Make a few practice runs in scrap or unseen areas to determine the proper position of the torque adjustment collar. NOTE: The torque adjustment collar may be set to any number at any time. However, the torque adjustment collar is only engaged during screwdriving mode and not in drill and hammerdrill modes. Hammerdrill Operation (Figure 5) 1. Select the desired speed/torque range using the gear shifter to match the speed and torque to the planned operation. Set the mode control collar (f) to the hammer symbol. 2. When drilling, use just enough force on the hammer to keep it from bouncing excessively. Too much force will cause slower drilling speeds, overheating, and a lower drilling rate. 3. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit when drilling as this will cause clogging of the bit flutes and a slower drilling speed. 4. When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the hole with the tool still running to help clear debris from the hole. 5. For masonry, use carbide-tipped bits or masonry bits. A smooth, even flow of dust indicates the proper drilling rate. MAINTENANCE Your DeWALT power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning. WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. The charger and battery pack are not serviceable. There are no serviceable parts inside. Lubrication Your power tool requires no additional lubrication. Cleaning WARNING: Blow dirt and dust out of the main housing with dry air as often as dirt is seen collecting in and around the air vents. Wear approved eye protection and approved dust mask when performing this procedure. WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid. CHARGER CLEANING INSTRUCTIONS WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. Do not use water or any cleaning solutions. 13
