4. When the desired torque is directly under the Lens Line, fold the Torque Adjusting Key back to the
stored and locked position. If desired, use the enclosed screw to affix the Torque Adusting Key in
place.
5. Replace the black vinyl cap on the rear of the screwdriver.
Operating The Screwdriver
1. Set torque per procedure above.
2. Insert bit (or adapter and socket) into Bit Holder on end of Shaft.
3. Engage fastener completely with bit (or socket).
4. Rotate screwdriver steadily until “click” is heard and felt. Further rotation will not tighten fastener futher.

Only in-line extensions, bits and adapters should be used with your screwdriver. The maximum
recommended overall length of any extension is six inches (6”).
Care and Cleaning
Return screwdriver to its lowest setting when it is to be stored for any period of time. Clean the screw-
driver with a soft, damp cloth. Do not immerse the screwdriver in cleaning fluids.
Calibration Instructions
Equipment Required: Torque tester of ± 1% Indicated Value accuracy or greater within the torque range of
the screwdriver, and 1/16” hex key
Procedure
1. Set screwdriver to test point.
2. Engage tool to torque tester.
3. Rotate screwdriver to obtain three (3) readings.
4. Evaluate readings.
a. If screwdriver is in specification:
1. And all three test points have been tested, test is complete.
2. And all three test points have not been tested, adjust to next test point and return to step 2.
b. If screwdriver is not in specification:
1. Return screwdriver to 20% setting.
2. Test on torque tester.
3. Disregard markings on shaft and adjust torque until consistent readings of 20% of capacity (8
in.lbs., or 0.8 Nm, or 8 KGF•cm) are obtained on tester.
4. Use 1/16” hex key to loosen the Lens Set Screw (below Lens on nose of screwdriver).
5. Rotate Lens until Lens Line is aligned with the shaft marking correlating to the test result.
6. Re-tighten Set Screw and retest.
