3. Setup
3.1 Unpacking and Inspection
Carefully remove all components from the textile pouch. Inspect each item for any signs of damage. Ensure all listed components are present.
3.2 Attaching Bits and Sockets
- Select the appropriate bit or socket for your application.
- Insert the bit or adapter into the 1/4" hexagonal drive of the torque wrench. Ensure it is fully seated and securely held.
- For sockets, attach them to the adapter (if using) or directly to the square drive of the wrench head.

4. Operating Instructions
4.1 Adjusting Torque Value
The Wera Safe-Torque A 2 allows for precise torque adjustment within its 2-12 Nm range. To adjust the torque:
- Pull down the green ring at the base of the handle to unlock the adjustment mechanism.
- Rotate the handle to set the desired torque value. The value is displayed in Newton-meters (Nm) and pound-force feet (lbf-ft) on the window.
- Once the desired torque is set, push the green ring back up to lock the handle in place. An audible and tactile click confirms the lock.

4.2 Tightening with Safe-Torque
The Safe-Torque mechanism ensures that once the set torque is reached, the tool will continue to turn without applying additional torque, preventing over-tightening.
- Ensure the torque wrench is set to the desired torque value and locked.
- Place the tool onto the fastener.
- Apply steady pressure and turn the handle clockwise.
- Once the set torque is reached, the mechanism will disengage, allowing the handle to turn freely without increasing torque. This is indicated by an audible and tactile signal.
- Stop turning once the mechanism disengages.

4.3 Reversible Ratchet Mechanism
The torque wrench features a 45-tooth reversible ratchet head, allowing for both tightening (clockwise) and loosening (counter-clockwise) of fasteners. The direction can be changed using the small lever on the ratchet head.

4.4 Torque ON/OFF Function
The wrench includes a Torque ON/OFF function. When set to 'OFF', the wrench operates as a standard ratchet without torque limitation. When set to 'ON', the Safe-Torque mechanism is active.

6. Maintenance
- Cleaning: Wipe the tool clean with a soft, dry cloth after each use. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the torque wrench and its components in the provided textile pouch in a dry, clean environment to prevent corrosion and damage.
- Calibration: For continued accuracy, it is recommended to have the torque wrench calibrated periodically by a qualified service center.
- Lubrication: Do not attempt to lubricate the internal mechanism unless specifically instructed by Wera.
7. Troubleshooting
7.1 Torque Adjustment Issues
If the torque adjustment dial becomes stiff or does not change the torque value:
- Ensure the green adjustment ring is fully pulled down before attempting to rotate the handle.
- Avoid forcing the adjustment mechanism. If it remains stuck, do not attempt to disassemble the tool.
- Contact Wera customer support or an authorized service center for assistance.
7.2 Inconsistent Torque Application
If the wrench does not consistently click or disengage at the set torque:
- Verify that the torque ON/OFF switch is set to 'ON'.
- Ensure the bit/socket is correctly seated and the fastener is clean and free of debris.
- Apply steady, smooth pressure when tightening. Jerky movements can affect accuracy.
- If the issue persists, the tool may require recalibration or service.
