To make adjustments, loosen the setscrew with a .035” hex key. With the right thumb and forenger, turn the2.
adjusting screw in a counterclockwise direction until it stops. Then in a clockwise direction, turn it one full
revolution.
Attach the screwdriver to the torque tester with a 1/16” hex key. Adjust screw clockwise or counterclockwise to3.
obtain a reading of approximately 10 in-oz on the torque tester when actuating the screwdriver.
The torque setting should now be made by turning the adjusting screw clockwise (right hand) to increase the4.
torque value and counterclockwise to decrease the torque value. Actuate the screwdriver on the tester drive
and observe the readings of each revolution. Continue adjustments and checking until the desired setting is
achieved.
Note: In some cases if may be necessary to make an additional small adjustment to the adjusting screw. Refer
to Step 3.
Tighten the setscrew to lock the adjusting screw.5.
Note: This torque screwdriver is a precision instrument and should be carefully handled, used and stored. If the unit
is dropped or subjected to abnormal handling or impact it should be checked on a Torque Tester before using.
