PROPER USE OF QE / QD SERIES TORQUE
WRENCHES
1. Preload click-type torque wrenches prior to use or when direction is changed. To preload,
set the wrench at 50% of full scale and exercise the wrench at least three times in both
directions on a fastener/fixture capable of safely withstanding the preload torque.
For preset model torque wrenches, proceed to step 5.
2. To unlock, push the lock ring toward the scale.
3. While holding lock ring in the unlocked position, set torque wrench to desired torque value
by rotating handle or barrel as shown in Figures 2 and 3 below.
Fig. 2 - Torque setting 50.
4. To lock handle, release the lock ring. It is locked when the ring clicks into position and the
handle does not turn.
5. To torque fastener, keep hand centered on the handle, apply a slow steady force in the
desired direction (clockwise or counterclockwise) until a click/impulse is heard or felt.
Stop pulling and allow the wrench to reset.
