Please read and understand entire manual, including all safety information, before using torque wrench. This tool is a precision measuring instrument. Handle with care and store properly. Do not attempt to increase leverage of this wrench with any other device. Failure to follow all instructions could result in damage to torque wrench, property damage, or injury.

• At low torque settings, pull wrench slowly to observe click.
• Wrench is shipped ready to use, calibrated and tested to an accuracy of +/- 4%. To maintain this accuracy, it is important that wrench is stored at lowest torque setting, 10 fl.-lb (13.6 Nm). This setting relieves extra tension on the internal spring, eliminating fatigue that can adversely affect accuracy.

SETTING TORQUE READING

This is a dual-range torque wrench marked with foot pounds (.-lb.) and Newton meters (Nm) on opposite sides of handle. The torque scale is marked on the handle body with more precise subdivisions on the knurled handle (Fig. A).

Fig. A

In these instructions the handle body scale will be referred to as the “main scale” and the knurled handle scale will be referred to as the “micrometer scale”.

Tighten/adjust lock nut and knurled handle by hand only.

Foot Pounds (Example reading: 51 ft.-lb.

1. Locate lock nut on the end of handle. Unlock knurled handle by turning lock nut counterclockwise.
2. COARSE SCALE ADJUSTMENT (Fig. B): Using ft.-lb. scale, turn knurled handle until its top edge is even with the horizontal “50” mark on main scale and the “0” mark on micrometer scale is centered on vertical line of main scale.

Fig. B

3. FINE SCALE ADJUSTMENT (Fig. C): The micrometer scale divides the main scale markings into 10 divisions. Every micrometer scale marking equals 0.5 ft.-lb., also known as the minimum increment. To increase torque from 50 to 51, turn micrometer handle clockwise until “1” mark is centered on vertical line of main scale. 50 ft.-lb. (main scale) + 1 ft.-lb. (micrometer scale) = 51 ft.-lb.

Fig. C

4. Lock torque setting by turning lock nut clockwise until snug. Wrench is now set to measure 51 .-lb. of torque and ready to use.

Newton Meters (Example reading: 40.0 Nm)

Setting desired torque on the Nm scale uses the same procedure described above for ft.-lb. scale. The micrometer scale divides the main scale markings into 10 divisions. Every micrometer scale marking equals 0.69 Nm, also known as the minimum increment. To set a torque value of 40.0 Nm, turn knurled micrometer handle until top is aligned with “34.0” mark on main scale and the “0” mark on micrometer scale is centered on vertical line of main scale. To increase torque from 34.0 Nm to 40.0 Nm, turn micrometer handle clockwise until the “4” mark is centered on vertical line of main scale. 40.0 Nm – 34.0 Nm = 6 Nm. 6 Nm ÷ 0.69 ≈ 8 micrometer scale markings. Wrench is now set to measure 40.0 Nm of torque and ready to use.

WRENCH OPERATION

Fig. D illustrates the basic operation of the torque wrench. For accurate operation, grasp the knurled handle only and apply pulling force. When the desired torque setting is reached, the roller bearing and roller pin will roll over each other, causing a click you can hear and feel.

Fig. D ( Torque is measured in CLOCKWISE direction only)

MAINTENANCE AND STORAGE

1. If wrench has not been used for a long period of time, operate it several times at a low torque setting.This will allow internal lubricant to recoat moving parts.

2. When wrench is not in use, keep adjustment at lowest torque setting, 10 ft□. -lb. (13.6 Nm) (Fig. E). Do not turn handle below lowest torque setting.
   
   Fig. E

3. This wrench is a precision measuring instrument. Take care to operate wrench correctly. Store in a clean, dry environment.

4. Clean wrench by wiping with a clean, dry, lint-free cloth. Do not immerse in any type of liquid or cleaner. This may damage the internal components of the wrench.

NOTE

1. Do not attempt to increase leverage of this wrench with any other device.
2. Tighten/adjust lock nut and knurled handle by hand only.
3. As nut/bolt becomes snug, slow operation to a smooth, steady pull. Operating wrench too quickly or with too much force may cause you to miss the exact torque setting.
4. Stopping when you feel and/or hear the click.
5. At low torque settings, click can be subtle.Use extra care to release wrench at the proper point after it clicks.Use wrench in a quiet environment.
6. Do not use wrench to break free stuck fasteners.
7. When wrench is not in use, keep adjustment at lowest torque setting. Do not turn handle below lowest torque setting.
8. Wrench does not measure torque below 10 ft.-lb. (13.6 Nm).
9. If wrench has not been used for a long period of time, operate it several times at a low torque setting.This will allow internal lubricant to recoat moving parts.
10. Clean wrench by wiping with a clean, dry, lint-free cloth. Do not immerse in any type of liquid or cleaner. This may damage the internal components of the wrench.
