TORQUE WRENCH LX-185 USER MANUAL

LX-185 3-4 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.

• It is recommended to practice first 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 is 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 30 ftlb. (40.7 Nm). By utilizing this setting, any additional strain on the internal spring is relieved, minimizing fatigue that will 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 wil be referred to as the ‘micrometer scale” This torque wrench is dual-side marked with Foot-Pounds (ft-Ib) and Newton-Meters (Nm) on opposite sides of the wrench body.

SETTI TORQUE READING

FOOT POUNDS (Example of setting 130 ft.-Ib.)

1. 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.

2. Rotate the knurled handle until ts top edge aligns with the horizontal 120″ mark on the main scale, while the 0* mark on the micrometer scale is centered on the vertical line of the main scale.

3. The micrometer scale divides the main scale into 15 divisions, each marking representing 2 ft.lb.
   To adjust the torque from 1200 130 ftb., rotate the micrometer handle in a clockwise direction until the “10” mark (5 micro-movements) aligns with the vertical line on the main scale. This adds 10 ft-lb. to the main scale reading of 120 ft-lb., resulting in a total torque of 130 ft.-lb.

4. Lock the torque setting by turning the locking knob clockwise until snug. Wrench is now set to measure 130 ft-Ib. of torque and ready to use.

NEWTON METERS
To set the desired torque using the Nm scale, follow the same procedure as you would for the ft-lb. scale.
However, Itis essential to keep in mind that every mark/increment on the micrometer scale will now represent 2.71 Nm.
Contrasting with the ft.lb. setting procedure, where each mark on the micrometer scale represents 2 ft.Ib., when referring to the Nm setting, the value of each mark on the micrometer scale is 2.71.
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 271 Nm to accurately set the desired torque value.

WRENCH OPERATION

1. 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.
2. 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.
3. The wrench will automatically reset for the next operation after pressure is released.

SPECIFICATIONS

• Range – Ft-Lb: 30 ~ 300
• Range – Nm: 40.7~406.8
• Increment: 2 Ft-Lb (2.71 Nm)
• Accuracy: + 4 percent
• Length: 25 inch

• Standard: ASME B107.300 DIN-ISO-6789

Troque is measured exclusively in the clockwise direcktion 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 is reached, do not 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

OPERATE SLOWLY – Wrench “clicks” to noify when torque value is reached. Wrench does not stop applying force automatically.
LISTEN AND FEEL – At low torque settings clicks is suble. Learn to hear and feel the click.
‘STORE AT LOWEST SETTING – To maintain calibration, set wrench to lowest torque value befors storage.
MEASURES IN ONE DIRECTION – Wrench only measures torque i right hand (clockwise) direction.
