Dial Torque Wrench
Basic Operating Instructions
1. Turn the bezel until the black pointer is resting on zero.
2. Attach a socket or attachment to the square drive.
3. Place the socket or attachment over the fastener to be torqued. The torque
wrench handle must be perpendicular (90 degrees) to the centerline of the
drive, socket and fastener.
4. Load the torque wrench at a slow and steady rate until the black pointer
indicates the desired torque.
5. Stop applying force. The pointer should return to zero.
cautION : to prevent personal injury, wear eye
protection that meets aNSI Z87.1 and OSHa standards.

cautION: to prevent equipment damage,
•
Never use the torque wrench beyond its rated capacity. Maximum torque capacity is reached when the black
pointer rotates 180 degrees from zero. Exceeding the maximum torque capacity damages the wrench and voids
warranty. If the pointer does not return to zero after a torque application, it is an indication that the wrench
was overloaded.
•
Load the torque wrench to near maximum torque capacity before starting, or when changing directions, to
remove residual energy that may be present from a previous torque application.
•
threads on bolts, nuts, and other mating components must be clean, smooth, and lubricated to obtain accurate
and consistent torque readings.
•
Follow the manufacturer's recommended procedures for tightening fasteners. Never torque a fastener that is
already tightened. First loosen the fastener; then torque it to the desired value.
•
Never use the torque wrench as a nut breaker.
