Safety Information

Always observe the following safety precautions when using your torque wrench:

• Wear Eye Protection: Always wear ANSI-approved safety goggles or glasses when operating any tools.
• Do Not Exceed Maximum Torque: Never apply force beyond the specified maximum torque capacity of the wrench (200 in/lbs for this model). Over-torquing can damage the tool or the fastener.
• Avoid Using as a Breaker Bar: This torque wrench is a precision instrument. Do not use it to loosen seized fasteners or as a general-purpose breaker bar.
• Keep Clean and Dry: Ensure the wrench is clean and free of oil, grease, or debris before and after use to maintain accuracy and prevent slippage.
• Store Properly: Store the torque wrench in its protective case and set to the lowest torque setting (but not below the minimum) to relieve spring tension and preserve calibration.
• Regular Calibration: For critical applications, have your torque wrench calibrated periodically by a qualified technician.

Components

Familiarize yourself with the main components of your GEARWRENCH Micrometer Torque Wrench:

Figure 3: Key Components of the Torque Wrench

• Drive Head: The 1/4" square drive for attaching sockets. Features a thin profile, sealed teardrop head, and a flush reversing lever for easy direction changes.
• Main Scale: The primary scale on the wrench body, indicating major torque increments.
• Micrometer Scale: The rotating scale on the handle, used for fine torque adjustments.
• Adjustment Collar: The pull adjustment collar allows for quick and easy torque setting changes.
• Handle: Provides grip and leverage during operation.

Setup

To set the desired torque value:

1. Unlock the Adjustment Collar: Pull down the adjustment collar located at the base of the handle. This unlocks the micrometer scale.
2. Set Major Torque Value: Rotate the handle until the desired major torque value aligns with the edge of the adjustment collar on the main scale.
3. Set Fine Torque Value: Continue rotating the handle until the desired fine torque value on the micrometer scale aligns with the center line of the main scale.
4. Lock the Adjustment Collar: Release the adjustment collar. It should snap back into place, locking the torque setting. Ensure it is fully engaged before use.

Operating Instructions

Follow these steps to correctly apply torque:

1. Attach Socket: Select the correct size socket and attach it firmly to the 1/4" drive head.
2. Position Wrench: Place the socket onto the fastener. Ensure the wrench is positioned so you can pull it smoothly and steadily.
3. Apply Torque: Apply a slow, steady, and continuous pull to the handle. Do not jerk or use sudden movements.
4. Listen for Click: Continue pulling until you hear and feel a distinct "click" from the wrench. This indicates that the preset torque value has been reached.
5. Release Pressure: Immediately stop applying force once the click is felt.
6. Reset Wrench: After each use, return the wrench to its lowest torque setting (but not below the minimum) to relieve spring tension.

Maintenance

Proper maintenance ensures the longevity and accuracy of your torque wrench:

• Cleaning: Wipe the wrench clean with a soft, dry cloth after each use. Do not use harsh chemicals or solvents that could damage the finish or internal components.
• Lubrication: The internal mechanism is factory lubricated and generally does not require user lubrication. Avoid applying lubricants to the drive head or handle.
• Storage: Store the torque wrench in its original protective case in a clean, dry environment. Always set the wrench to its lowest torque setting (but not below the minimum) before storage to prevent fatigue of the internal spring.
• Avoid Dropping: Dropping the torque wrench can severely affect its calibration and internal mechanisms. Handle with care.
