LEXIVON LX-180 1 4 Inch Pound Torque Wrench

Product Information

Specifications

Product Name: Mini 1/4-Inch Drive Click Torque Wrench
Torque Range: 10~150 in.-lb./1.1~16.9 Nm
Model: LX-180

Product Usage Instructions

Setting Torque Reading

To set torque reading:

Slide down locking collar to enable micrometer scale adjustment.
Turn the knurled handle until its top edge aligns with the horizontal 100 mark on the main scale.
Ensure the 0 mark on the micrometer scale is centered on the vertical line of the main scale.
Adjust the micrometer knurled handle to set the desired torque reading.
Slide up locking collar to maintain the torque setting.

Wrench Operation

To operate the wrench:

Install the proper socket/attachment on the square drive and apply to nut/bolt.
Keep your tightening hand centered on the knurled handle for accurate results.
Tighten nut/bolt slowly until a ‘CLICK’ or ‘IMPULSE’ is heard or felt.
Stop pulling and release pressure on the handle when the click is detected.

Maintenance and Storage

Maintenance tips:

Operate the wrench at a low torque setting if it has not been in use for a long time.
Keep the torque wrench scale at the lowest setting (10 in.-lb. mark on main scale and ‘0’ mark on micrometer scale) when not in use.

Frequently Asked Questions

Q: Can I use the wrench to break free stuck fasteners?

A: No, do not use the wrench to break free stuck fasteners. Tighten/adjust sliding lock and knurled handle by hand only.

Q: What should I do if the click is not very noticeable at low torque settings?

A: Use the wrench in a quiet environment to better hear and feel the click at low torque settings.

ATTENTION

Please read and understand the 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 the leverage of this wrench with any other device. Failure to follow all the instructions could result in damage to a torque wrench, property damage, or physical injury.
At low torque settings, click might be subtle; pull the wrench slowly to observe click – Learn to hear and feel the click.
The wrench is shipped ready to use, calibrated and tested to an accuracy of +/- 4% in the CLOCKWISE direction and +/- 6% in the COUNTERCLOCKWISE direction. To maintain this accuracy, it is crucial that the wrench is stored at the lowest torque setting, 10 in.-lb. (1.1 Nm). This setting relieves extra tension on the internal spring, reducing fatigue that can adversely affect accuracy.

SETTING TORQUE READING

This is a dual-range torque wrench marked with inch-pounds (in.-lb.) and Newton-meters (Nm) on opposite sides of the wrench body. The micrometer scale has two rows, the top row is for in.-lb. and the bottom row is for Nm. The torque scale is marked on the wrench body with more precise subdivisions on the knurled handle (Fig. B) throughout the instruction manual the wrench body scale will be referred to as the “main scale” and the knurled handle scale will be referred to as the “micrometer scale”.

Wrench measures torque in clockwise and counterclockwise directions.

INCH POUNDS

(Example reading: 105 in.-lb.)

Use the top row of the Micrometer scale

Slide down the locking collar to enable micrometre scale adjustment.
Turn the knurled handle until its top edge is even with the horizontal “100” mark on the main scale, while the “0” mark on the micrometre scale is centered on the vertical line of the main scale.
The micrometre scale’s top row divides the main scale markings into 10 divisions. Every micrometre scale marking equals 1 in.-lb., also known as the minimum increment. To increase the torque from 100 to 105, turn the micrometer knurled handle clockwise until the “5” mark of the top row is centred on the vertical line of the main scale. 100 in.-lb. (main scale) + 5 in.-lb. (micrometer scale) = 105 in.-lb.
Slide up the locking collar to maintain the torque setting. The wrench is now set to measure 105 in.-lb. of torque and is ready to use.
IMPORTANT – Store the wrench at its lowest setting 10 in.-lb. (1.1 Nm) to maintain torque accuracy.

NEWTON METERS

(Example reading: 6.5 Nm)

Use the bottom row of the micrometre scale

Setting desired torque on the Nm scale uses the same procedure described above for in-lb. scale. The micrometre scale’s bottom row divides the main scale markings into 10 divisions. Every marking equals 0.113 Nm, also known as the minimum increment. To set a torque value of 6.5 Nm, turn the knurled micrometer handle until the top is aligned with “5.6” mark on main scale and the “0” mark on the bottom row of the micrometre scale is centered on the vertical line of the main scale. To increase torque from 5.6 to 6.5, turn the micrometer handle clockwise until the 0.90 mark is centred on the vertical line of the main scale. 5.6 Nm (main scale) + 0.90 Nm (micrometer scale) = 6.5 Nm. Slide up the locking collar to maintain torque setting. The wrench is now set to measure 6.5 Nm of torque and is ready to use.

WRENCH OPERATION

Install proper socket/attachment on the square drive and apply to nut/bolt. Make sure to keep your tightening hand centered on the knurled handle for accurate results.
Operate the wrench to tighten nut/bolt and slow operation when they become snug to a smooth and steady pull. When a ‘CLICK’ or ‘IMPULSE’ is heard or felt; stop pulling wrench and release pressure on handle.
Wrench will automatically reset for next operation after pressure is released.

Torque is measured in both clockwise And counterclockwise directions.

IMPORTANT OPERATION NOTICE

Operating wrench too quickly or with too much force may cause you to miss the exact torque setting. Do not continue to pull after torque setting is reached. Doing so will damage the wrench’s internal mechanism.
At low torque settings, the click can be subtle. Use the wrench in a quiet environment – Learn to hear and feel the click.
Do not use the wrench to break free stuck fasteners. Tighten/adjust sliding lock and knurled handle by hand only. Wrench does not measure torque below 10 in.-lb./1.1 Nm.

MAINTENANCE AND STORAGE

If the wrench has not been in use for a long time, operate it several times at a low torque setting. This will allow internal lubricant to recoat internal components.
Keep the Torque Wrench Scale at the lowest setting when not in use. The lowest setting: 10 in.-lb. mark on the main scale and ‘0’ mark on the micrometre scale. DO NOT turn the handle below the lowest torque setting.
Clean the wrench by wiping it with a clean, dry, lint-free cloth. Do not immerse in any liquid or cleaner, as it can damage the wrench’s internal components

TORQUE UNIT CONVERSION TABLE

CAUTION:

STORE AT LOWEST SETTING – To maintain calibration, set wrench to the lowest torque value before storage.
OPERATE SLOWLY – Wrench “clicks” to notify when torque value is reached. The wrench does not stop applying force automatically.
LISTEN AND FEEL – At low torque settings clicks is subtle. Learn to hear and feel the click.
PRECISION TOOL – Do not use for extreme operations like breaking loose stuck fasteners.
PRACTICE FIRST – Try wrenching a non-critical fastener first to learn how it works.
