Note : The Torque Screwdriver is marked with Inch Pounds. The following instructions illustrate use in Inch Pounds.

1. BEFORE EVERY USE, exercise Torque Screwdriver. Pull down Adjusting Ring, then perform the following exercise three times: a. Turn Handle to the right until maximum torque setting is reached. b. Turn Handle to the left until minimum torque setting is reached.
   CAUTION! To prevent damage to the Torque Screwdriver, do not use for loosening fasteners.

2. Clean the fastener’s threads. Dirty threads may result in a misleading torque reading.

3. Select bit that properly fits the fastener. Press bit firmly in Hex Drive.
   Note: Thread fastener with another tool until it is snug, then finish the operation with the Torque Screwdriver.

4. Pull down Adjusting Ring and hold in place while adjusting torque.

5. To set torque value to 24: a. Turn Handle until the “0” on Scale Ring lines up with the “20” on the Main Torque Value Scale. b. Continue to turn Handle until the “4” on Scale Ring lines up with center line on Main Torque Scale. The torque value is set to 24 in-lb. (20 + 4 = 24).
