LX-182 3-8 Inch Drive Click Torque Wrench
ATTENTION
-
Before using the torque wrench, make sure to read and understand the entire manual, including safety information.
Not following the instructions could result in damage to the tool, property, or personal injury.
Treat this precision measuring tool with care and store it properly. Avoid using any additional devices to increase leverage of this wrench.
Itis recommended to practice fist with a non-critical application. Be aware that at low torque settings, the click may be subtle; pull the wrench slowly to observe and learn to recognize the click both audibly and by feel. -
The wrench s calibrated &delivered in a ready-to-use condition. Tested to an accuracy of +/- 4%. To preserve this accuracy, it’s crucial to store the wrench at its lowest torque setting of 10 ftdb. (13.6 Nm). By utiizing this setting, any additional strain on the internal spring is relieved, fatigue that will accuracy, minimizing impact the wrench’s accuracy.
INTRODUCTION
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” This torque wrench is dual-side marked with FootPounds (ft-lb) and
Newton-Meters (Nm) on opposite sides of the wrench body.
SETTING TORQUE READING
FOOT POUNDS (Example of setting 53 ft.b.)
-
Find the locking knob positioned at the end of the knurled handle. Release the knurled handle by rotating the locking knob in a counterclockwise direction.
-
Rotate the knurled handle until its top edge aligns with the horizontal *50″ mark on the main scale, while the “0° mark on the micrometer scale is centered on the vertical line of the main scale.
-
The micrometer scale divides the main scale into 10 divisions, each marking representing 0.5 ft.-b.
To adjust the torque from 50 to 53ft.Jb., rotate the micrometer handle in a clockwise direction until the “3” mark (6 micro-movements) aligns with the vertical line on the main scale. This adds 3 ft-Ib. to the main scale reading of 50 ft-lb,, resulting in a total torque of 53 ft-1b. -
Lock the torque setting by tuming the locking knob clockwise until snug. Wrench is now set to measure 53 ft.Ib. of torque and ready to use.
NEWTON METERS
To set the desired torque using the N scale, follow the same procedure as you
would for the ft.Ib. scale,
However, It s essential to keep in mind that every mark/increment on the
micrometer scale will now represent 0.678 Nm.
Contrasting with the ftlb. setting procedure, where each mark on the
micrometer scale represents 0.5 ft.lb., when referring to the Nm setting, the
value of each mark on the micrometer scale is 0.678.
When using the torque wrench’s Newton Meter scale, it’s crucial to keep this
conversion factor in mind. Make sure you calculate each increment as 0.678 Nm
to accurately set the desired torque value.
WRENCH OPERATION
- Install proper socket/attachment on the square drive and apply to nut/bolt. Make sure tokeep your tightening hand centered on the knurled handle for accurate resulfs.
- Operate the wrench to tighten the nut/bolt, gradually increasing the force until they are snug. Slow down your operation and apply a smooth and steady pull. When you hear or feel a ‘CLICK’ or ‘IMPULSE’, stop pulling the wrench and release the pressure on the handle.
- The wrench will automatically reset for the next operation after pressure is released.

DIN-ISO-6789
Torque is measured exclusively in the clockwise direction only.
IMPORTANT OPERATION NOTICE
Operating the wrench too quickly or with excessive force may lead to missing
the precise torque setting.
Once the torque setting s reached, do ot continue pulling, as this can damage
the internal mechanism of the wrench
At low torque settings, the click may be subtle. It is recommended to use the
wrench in a quiet environment and learn to both hear and feel the click for
proper torque application.
Do not attempt to use the torque wrench to loosen stuck fasteners.
Tighten/adjust the locking knob and the knurled handle by hand only.
Remember, torque is measured exclusively in the clockwise direction.

MAINTENANCE AND STORAGE
This wrench is a precision
measuring instrument. Take care and operate correctly. Store in a clean, dry
environment.
Clean by wiping with a dry, lint-free cloth.
Do not immerse in any liquid or cleaner, as it can damage the internal
components of fda areaB

CAUTION:
PRECISION TOOL – Do not use for extreme operation like breaking loose stuck
fasteners.
PRACTICE FIRST – Try wrench on a non-crtical fastener fist to leam how it
works.
OPERATE SLOWLY – Wrench “clicks” to notify when torque value is reached.
Wrench does not stop applying force automatically.
LISTEN AND FEEL – At low torque settings clicks is subtle. Learn to hear and
feel the click.
STORE AT LOWEST SETTING – To maintain calibration, set wrench to lowest torque
value before storage.
MEASURES IN ONE DIRECTION – Wrench only measures torque in right hand
(clockwise) direction.
