**Advantages:**
1. Dual-Direction Functionality: Offers the flexibility to work in both clockwise and anti-clockwise directions.
2. Wide Torque Range: The range of 25-220 Nm caters to varied tasks, making it versatile.
3. 1/2-Inch Drive: Standard size which fits a wide variety of sockets.
4. Click Mechanism: Users can physically feel and hear when the desired torque level is achieved.
Disadvantages:
Requires Calibration: Like many torque wrenches, accuracy might decrease over time and may require recalibration.
Not Suitable for All Tasks: The 25-220 Nm range might not be ideal for extremely delicate or very heavy-duty tasks.
Potential Over-Torquing: If not used properly, there’s a risk of applying too much force and damaging the bolts.
Problems and Solutions:
Problem: Difficulty in reading the torque setting due to unclear markings.
Solution: Ensure the scale is clean, and use it in well-lit conditions. Consider using a magnifying glass if necessary.
Problem: The wrench does not ‘click’ at the set torque.
Solution: It might be due to wear and tear or misuse. Periodic calibration or maintenance might be needed.
Problem: The wrench slips off bolts and nuts.
Solution: Ensure you’re using the correct socket size and that the tool and fastener are clean from grease or dirt.
