To stop tool, release the switch. The variable speed trigger switch permits speed control. The farther the trigger switch is depressed, the higher the speed of the tool. To lock the switch in the on position for continuous operation, depress the trigger switch and push up the locking button. The tool will continue to run. To turn the tool off, from a locked on condition, squeeze and release the trigger once. Before using the tool (each time), be sure that the locking button release mechanism is working freely. Be sure to release the locking mechanism before disconnecting the plug from the power supply. Failure to do so will cause the tool to start immediately the next time it is plugged in. Damage or injury could result.The reversing lever is used to reverse the tool for backing out screws. It is located above the trigger, shown in Figure 1. To reverse the screwdriver, turn it off and push the reversing lever to the right (when viewed from the back of the tool). To position the lever for forward operation, turn the tool off and push the lever to the left. Dead Spindle Action 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 The 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 1/4" hex drive quick change chuck (Figure 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. Depth Sensitive Units (DW251, DW252, DW255, DW257, DW262, DW265, DW272, DW274, DW274W, DW274-220, DW276, DW276-220) 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. NOTE: Align ribs on inside of depth locator with grooves in clutch housing before snapping into place. CHANGING BIT TIP 1. Pull forward on adjustment collar and remove it from clutch housing (see Figure 3). 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. Nutsetting Units (DW260, DW263, DW266, DW266-220) 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 9/16" ID for 3/8" nutsetters and 1/2" ID for 5/16" nutsetters. Match locator to desired size nutsetter or bit holder. 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 (see Figure 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 1/16" into the locator. 3. Test drive a fastener in scrap material to determine if seating is correct. 4. Adjust following the g...
