The clutch is designed to slip at a preset torque to prevent damage to the tool or the screw, and to prevent driving screws too deep. Use lower torque settings for screw- ing into soft materials with short screws, and higher settings for harder materials and longer screws. The clutch does not slip when set in the drill position.
To adjust the torque:
1.Rotate the clutch ring shown in Figure 4 to adjust the torque. The clutch will slip easiest in the number 1 setting; the torque increases as the number increases.

2.Turn the clutch ring to the drill setting to prevent the clutch from slipping.
Note: DO NOT operate the drill with the clutch set between the highest number and the drill setting. The clutch mechanism may be damaged.
When the clutch is in the drill posi- tion, the drill can twist severely, causing a sprained wrist or pinching your hand between the drill and a solid object. Hold the drill with both hands and be aware of the drill posi- tion to prevent injury.
Operating this equipment has the potential for flying debris to cause eye injury. Always wear safety glasses or goggles when operating equipment. Everyday glasses or reading glass- es only have impact resistant lenses, they are not safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards Institute (ANSI).
Use the lowest possible torque setting when driving fasteners to prevent dam- age to the screw, and to prevent driving screws too deep.
To drive screws:
1.Install a screwdriver bit that matches the screw head pattern.
2.Set the torque to an appropriate set- ting for the workpiece and set the direction to clockwise (forward).
3.Place the screwdriver bit into the screw and the screw firmly against the workpiece, start the drill slowly and gradually increase speed, while apply- ing pressure to drive the screw into the workpiece.
Note: You may wish to drill a pilot hole before driving the screw, depending on the workpiece and screw type.
To remove screws:
1.Set the direction to counterclockwise (reverse) and the clutch to the highest torque setting.
2.Place the screwdriver bit into the screw, pull the drill trigger, and push lightly to keep the bit in the screw.
