2.To install a drill/screwdriver bit, hold the Chuck Sleeve firmly in place and turn the Chuck (12) counterclockwise. Insert the shank of the bit all the way into the Chuck (12). While holding the Chuck Sleeve in place, turn the Chuck clockwise to lock the bit in place. The Chuck (12) accepts up to 3/8” diameter bits. Insert the appropriate bit for your application and tighten the Chuck (12) firmly. (See Figure E, above.)

3.Secure the workpiece in place, using a vise or clamps (not included).

4.The Torque Setting Ring (8) allows you to select 16 different driving torque settings, depending on the job required.

Torque Settings (1-8):

The different numbers on the Ring are an indication of how much torque the screwdriver will apply to the bit before the clutch slips, allowing the bit to stop and helping to prevent damage to the screw, bit, or workpiece. The higher the number, the more torque is applied before the clutch slips. Unless you are drilling, always start with a lower number to help prevent damage. This drill also has torque settings between the numbers to allow a greater range of control.
