WORK AREA a. Keep work area clean and well lit. Cluttered and dark areas invite accidents. b. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. c. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. 2. ELECTRICAL SAFETY a. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. b. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. e. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. 3. PERSONAL SAFETY a. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. b. Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. c. Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.

SAFETY INSTRUCTIONS FOR POWER TOOLS When using power tools, always observe the safety regulations applicable in your country to reduce the risk of fire, electric shock and personal injury. Read the following safety instructions before attempting to operate this product. Keep these instructions in a safe place. General Safety Rules WARNING! Read all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains operated (corded) power tool or battery operated (cordless) power tool. SAVE THESE INSTRUCTIONS 1 d. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. e. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. g. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust related hazards. 4. POWER TOOL USE AND CARE a. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. b. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. c. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. d. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. e. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g. Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. 5. SERVICE a.

To position the lever for forward operation, turn the tool off and push the lever to the left. Dead Spindle Action FIG. 3 All DEWALT screwdrivers provide a dead output spindle to permit fasteners to be located easily in the driving accessory. Clutches are held apart by light spring pressure permitting the driving clutch to rotate without turning the driven clutch and accessory. When sufficient forward pressure is applied to the unit, the clutches engage and rotate the spindle and accessories. A reversing switch makes it possible to drive or loosen either right or left hand screws. Accessory Assembly FIG. 2 2. Use pliers to remove worn bit and install new bit tip. DEPTH ADJUSTMENT Follow the graphic on the collar to increase or decrease the fastening depth. To seat the screw deeper in the workpiece, turn the adjustment collar to the right. To seat the screw higher in the workpiece, turn the adjustment collar to the left. The 6.35 mm (1/4") hex drive ball lock chuck is used on all depth sensitive and drywall screwdrivers. Assemble accessories by engaging the hex spindle and tapping lightly on the accessory until it snaps in place. Usually pliers are required to remove the accessory by pulling forward. The 6.35 mm (1/4") hex drive quick change chuck (Fig. 2), is used on all Versa Clutch™ units. A ball retainer provides positive locking of all accessories in the chuck. Pull forward on the ball retainer and hold while inserting or removing accessories. Release for positive accessory retention. Nutsetting Units (DW260-XE, DW263-XE, DW266-XE, DW266-220-XE) INSTALLING AND CHANGING NUTSETTERS AND LOCATORS Depth Sensitive Units for Drill Point Screws 1. To change or install a new nutsetter: a. Pull forward on adjustment collar and remove from clutch housing. b. Pull nutsetters straight out with pliers c. Select nutsetter size desired. d. Two locators are supplied, a 14.3 mm (9/16") ID for 3/8" nutsetters and 12.7 mm (1/2") ID for 5/16" nutsetters. Match locator to desired size nutsetter or bit holder. Depth Sensitive Units (DW251-XE, DW252-XE, DW255-XE, DW256-XE, DW257-XE, DW258-XE, DW262-XE, DW265-XE, DW272-XE, DW274-XE, DW274W-XE, DW274-220-XE, DW276-XE, DW276-220-XE) TO CHANGE BIT HOLDERS 1. Pull forward on adjustment collar and remove from clutch housing. 2. Pull bit holder straight out with pliers if it is difficult to remove. 3. Push new bit holder into spindle until ball lock snaps in groove in bit holder shank. 4. Replace adjustment collar by snapping over retaining ring. 4 FIG. 4 NUTSETTER 2. Place nutsetter into clutch housing and push end of nutsetter until ball lock snaps into groove of nutsetter shank. 3. Reassemble adjustment collar by snapping over springs (Fig. 4). NOTE: Align ribs on inside of depth locator with grooves in clutch housing. DEPTH ADJUSTMENT 1. For washer head screws: rotate adjustment collar until end of nutsetter is flush with end of locator. 2. For large washer head and sealer screws: adjust as above until nutsetter is recessed approximately 1.6 mm (1/16") into the locator. 3. Test drive a fastener in scrap material to determine if seating is correct. 4. Adjust following the graphic printed on the tool. VERSA CLUTCH™ UNITS (DW267-XE, DW268-XE, DW268-220-XE, DW268G-XE, DW269-XE) External adjustment of all Versa Clutch™ units for a wide range of fastener sizes is fast and easy as follows (Fig. 5): 1. Pull forward, then rotate collar in increase direction (stamped on adjustment collar) to increase the amount of clutch engagement and torque output. 3. Test drive a fastener into a scrap piece to check proper fastener seating. It is normal after a period of use to require a slightly different collar setting due to wear on the clutch faces. NOTE: With Versa Clutch™, the operator has the ability to “override” clutch ratchet if a fastener hits a wood knot, variable hardness in steel work pieces or incorrect pilot holes. Increased operator pressure will usually cause the clutches to pick-up and continue to seat the fastener. Further, a quick twist of the collar will change the clutch setting to overcome most driving difficulties and will provide for immediate change in torque output giving the operator the option to drive a wide range of fastener sizes. Positive Clutch Units (DW281-XE, DW282-XE, DW284-XE) 1. Install proper bit and set screwdriver for correct rotation. 2. Place fastener on bit and contact work. 3. Apply steady pressure on screwdriver to keep clutches engaged and bit in contact with fastener. 4. Upon fastener seating, clutches will ratchet. Disengage bit from fastener. MAINTENANCE WARNING: Shock Hazard. To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before making any adjustments or removing/installing attachments or accessories. FIG. 5 Cleaning WARNING: Blow dirt and dust out of all air vents with dry air at least once a week. Wear proper ANSI Z87.1 (CAN/CSA Z94.3) eye protection and proper NIOSH/OSHA/ MSHA respiratory protection when performing this. WARNING: Never use solvents or other harsh chemicals for cleaning the nonmetallic parts of the tool. These chemicals may weaken the plastic materials used in these parts.
