Sears Torque Wrench Operating Instructions

Shade tree mechanics are likely to use two main types of torque wrenches. "Beam type" torque wrenches are cheaper and require the user to read an analog scale that stretches across a beam on the top of the wrench just under the handle. With a "click type" torque wrench the mechanic sets the desired torque on a round gauge, and the head of the wrench slips when the fastener is tightened to that preset value. Sears sells more torque wrenches than any other company in the United States.

Instructions

1

Wear safety glasses, because metal fasteners sometimes break. Attach a socket to the torque wrench.

2

Disregard torque readings less than 20 percent of the full scale. Do not estimate torque readings greater than 100 percent of the full scale.

3

Inspect and distrust any torque wrench you drop or that you suspect may have been dropped by someone else.

4

Store click-type torque wrenches with the gauge set to the lowest setting. Always store them in protective cases.

5

Apply a specific torque value to a fastener with a torque wrench only during final tightening. Never use a torque wrench as the primary means of tightening or loosening fasteners. Use a socket wrench instead.

6

Grasp a torque wrench in the center of the handle, because torque wrenches are length specific. If you must use two hands, put one hand on top of the other.

7

Torque a fastener with a slow, steady movement. Never jerk a torque wrench.

8

Recalibrate a torque wrench after every 5,000 uses.
