Safety Information

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

• Wear appropriate personal protective equipment, such as safety glasses, when operating the tool.
• Ensure the workpiece is securely fastened and stable before applying torque.
• Do not exceed the maximum torque setting of 210 Nm.
• Do not use the torque wrench to loosen fasteners. It is designed for tightening only.
• Avoid dropping the tool, as this can affect its calibration and accuracy.
• Store the wrench at its lowest torque setting (28 Nm) when not in use to preserve spring tension and maintain accuracy. Do not set below the minimum.
• Keep the tool clean and free from oil, grease, or other contaminants that could affect grip or operation.

Setup

The Silverline 633567 Torque Wrench requires minimal setup before use.

1. Unpack: Carefully remove the torque wrench and accessories from the storage case.
2. Inspect: Before each use, visually inspect the wrench for any signs of damage, wear, or corrosion. Ensure the ratchet head operates smoothly.
3. Attach Socket/Accessory: Select the appropriate socket for your fastener. If needed, attach the 125mm extension bar or the 1/2" to 3/8" drive adaptor to the 1/2" square drive of the wrench. Then, attach your socket to the extension or adaptor.

Operating Instructions

Follow these steps to accurately apply torque using your Silverline 633567 Torque Wrench:

1. Unlock the Handle: Locate the locking ring at the base of the handle. Rotate it counter-clockwise to unlock the adjustment mechanism.
2. Set Torque Value:
   • The main scale on the wrench body indicates major torque values (e.g., 28, 42, 56 Nm).
   • The knurled handle has a secondary scale for finer adjustments (0-14 Nm).
   • Rotate the knurled handle to align the desired main torque value with the center line on the wrench body.
   • Then, continue rotating the handle until the desired fine adjustment value on the handle's scale aligns with the center line. For example, to set 100 Nm, rotate the handle until 98 Nm is aligned on the main scale, then rotate further until '2' on the handle's scale aligns with the center line (98 + 2 = 100 Nm).

3. Lock the Handle: Once the desired torque value is set, rotate the locking ring clockwise until it is fully tightened. This secures the setting and prevents accidental changes during use.
4. Apply Torque:
   • Place the socket onto the fastener.
   • Hold the wrench firmly by the handle. Apply smooth, steady pressure in a clockwise direction (for right-hand threads) until you hear and feel a distinct "click" or "break" in the wrench. This indicates that the preset torque has been reached.
   • Do not continue to apply force after the click.

5. Reset for Storage: After use, always reset the torque wrench to its lowest setting (28 Nm) before storing it. This relieves tension on the internal spring, helping to maintain the wrench's calibration and accuracy over time.

Maintenance

Proper maintenance will extend the life and accuracy of your torque wrench:

• Cleaning: After each use, wipe the wrench clean with a soft, dry cloth. Do not use solvents or harsh chemicals, as these can damage the finish or internal components.
• Lubrication: The internal mechanism is factory-lubricated and generally does not require user lubrication. If the ratchet head becomes stiff, a small amount of light machine oil can be applied to the pivot points, but avoid getting oil into the main body of the wrench.
• Storage: Store the torque wrench in its original protective case in a dry, clean environment, away from extreme temperatures and humidity. Always reset the wrench to its lowest torque setting (28 Nm) before storage.
• Calibration: Torque wrenches are precision instruments and may require periodic re-calibration, especially with frequent use or if dropped. Consult a professional calibration service if you suspect accuracy issues.
