Introduction

This manual provides detailed instructions for the safe and effective use of your VANPO 3/8 Inch Drive Adjustable Torque Wrench, Model VP018. This precision tool is designed for accurate torque application in various tasks, including HVAC, automotive, and industrial repairs. Please read this manual thoroughly before operation to ensure proper usage and to prevent damage to the tool or the workpiece.

Safety Information

• Always wear appropriate personal protective equipment, such as safety glasses, when using this tool.
• Ensure the workpiece is securely fastened before applying torque.
• Do not exceed the maximum torque capacity of the wrench (45 Ft.lb / 61 Nm).
• Never use the torque wrench as a breaker bar or for loosening fasteners. It is designed for tightening only.
• Avoid dropping the wrench, as this can affect its calibration and accuracy.
• Keep the wrench clean and free from oil or grease to maintain a secure grip.
• Store the torque wrench in its protective case when not in use, and set it to its lowest torque setting to relieve spring tension.
• Regularly check the wrench for any signs of damage or wear. Do not use a damaged tool.

Product Overview and Components

The VANPO VP018 torque wrench features an interchangeable head design, allowing for versatile applications. It comes equipped with both a 38mm adjustable open-end spanner head and a 1/2" 72-tooth ratchet head.

The wrench features a dual scale for precise torque settings in both Foot-pounds (Ft.lb) and Newton-meters (Nm). The scale is clearly marked for easy reading and adjustment.

Setup

1. Select the Appropriate Head: Choose between the 38mm adjustable open-end head or the 1/2" ratchet head based on your application.
2. Attach the Head: Align the chosen head with the 9x12mm square interface on the torque wrench body. Insert the head firmly until it clicks into place. For secure attachment and removal, use a 4mm flat head hex wrench if needed, as indicated in the product features.
3. Set the Torque Value:
   • Locate the locking knob at the base of the handle.
   • Pull down the locking knob and hold it.
   • Rotate the handle to adjust the main scale and the micro-scale until the desired torque value (e.g., 5-45 Ft.lb or 7-61 Nm) is displayed.
   • Release the locking knob. It will automatically rebound to lock the set value. Verify the setting before use.

Operating Instructions

1. Prepare the Fastener: Ensure the fastener and mating surfaces are clean and free of debris.
2. Position the Wrench: Place the wrench head onto the fastener, ensuring a snug fit. For the open-end head, position it to allow for a full pull. For the ratchet head, ensure the direction switch is set for tightening.
3. Apply Torque: Apply smooth, steady pressure to the handle. Do not jerk or apply sudden force.
4. Listen for the "Click": Continue applying pressure until you feel and hear a distinct "click" from the wrench. This indicates that the preset torque value has been reached.
5. Stop Applying Force: Immediately stop applying force once the "click" is felt/heard. Further tightening can over-torque the fastener and damage the workpiece or the wrench.
6. Repeat if Necessary: For critical applications, it is recommended to re-check the torque after a short period, especially if the fastener is new or has been subjected to vibration.

Maintenance

• Cleaning: Wipe the wrench clean with a soft, dry cloth after each use. Do not use solvents or harsh chemicals, as these can damage the finish or internal components.
• Storage: Store the torque wrench in its original protective case in a dry, clean environment. Always set the torque to the lowest setting (e.g., 5 Ft.lb or 7 Nm) before storage to relieve tension on the internal spring, which helps maintain accuracy over time.
• Calibration: Torque wrenches are precision instruments and require periodic calibration to maintain accuracy. It is recommended to have your wrench calibrated annually or after any significant impact or misuse by a qualified calibration service.
• Inspection: Before each use, inspect the wrench for any signs of damage, such as cracks, bends, or excessive wear on the heads or handle. Do not use a damaged wrench.
