To set screwdriver to desired torque:
1. Determine proper torque to be applied to the
fastener.
2. Use a certified torque tester that is accurate within a
range suited to screwdriver torque range.
3. Remove end cap at the base of screwdriver.
(See Figure I)
WHEN APPLYING TORQUE THE SCREWDRIVER 
MUST BE KEPT PERPENDICULAR TO THE 
PLANE OF USE (EITHER HORIZONTAL OR 
VERTICAL). INACCURACIES IN TORQUE 
READINGS MAY OCCUR FROM APPLYING A 
“SIDE LOAD”. 
6. Adjust until the desired torque setting is reached.
Turn the screwdriver several more times on the 
tester and fine tune the setting to as repeatable a 
number as possible. Replace end cap. 
7. Install the proper bit into the hex receiver and the
screwdriver is ready to use.
8. To torque fastener keep hand centered on the
handle. Turn handle until a click/impulse is heard or 
felt. Stop turning, the screwdriver will automatically 
reset for the next operation.

4. Place screwdriver on tester and cycle several times
observing the torque setting displayed on the 
tester. 
5. With a 1/8” hex key adjust the set screw at
the base of the preset torque screwdriver. Turn 
clockwise (cw) to increase the amount of torque and 
counterclockwise (ccw) to decrease the amount of 
torque.
