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 FIG. 2 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.
