2. Setup and Torque Adjustment

Properly setting the torque value is crucial for accurate and safe operation. Follow these steps to adjust your Uharbour torque wrench:

1. ปลดล็อคที่จับ: Locate the locking mechanism at the base of the handle. Slide it down to unlock the adjustment mechanism.
2. Adjust Torque Value: Rotate the handle to set the desired torque value. The main scale indicates major increments (e.g., 20, 40, 60 in-lb), while the micro-scale on the handle provides finer adjustments (e.g., 0, 2, 4, 6, 8 in-lb). Add the value from the main scale to the value aligned on the micro-scale to get your total torque setting. For example, if the main scale shows 40 in-lb and the micro-scale shows 6 in-lb, the total setting is 46 in-lb.
3. ล็อคที่จับ: Once the desired torque is set, slide the locking mechanism back up to secure the handle. This prevents accidental changes during use.

3. คู่มือการใช้งาน

Using the torque wrench correctly ensures fasteners are tightened to the manufacturer's specifications, preventing damage from over-tightening or loosening from under-tightening.

1. Select the Correct Bit/Socket: Choose the appropriate Hex or Torx bit, or use the 1/4" adapter with a suitable socket, for your fastener. The set includes Hex bits (H2, H2.5, H3, H4, H5, H6, H8, H10) and Torx bits (T10, T25, T30).
2. Attach Bit/Socket: Press the quick-release button on the ratchet head to attach the selected bit or adapter. Ensure it is securely seated.
3. ตั้งค่าแรงบิด: Follow the "Setup and Torque Adjustment" section to set the required torque value.
4. ใช้แรงบิด: Place the wrench onto the fastener. Apply steady, increasing pressure to the handle in the tightening direction (clockwise for most fasteners). Continue applying pressure until you hear and feel a distinct "click." This click indicates that the preset torque value has been reached.
5. อย่าขันให้แน่นเกินไป: Once the click is heard, stop applying force immediately. Continuing to tighten after the click can lead to over-torquing and damage to the fastener or component.
6. Dual-Direction Use: The 72-tooth ratchet head allows for both clockwise and counterclockwise operation. Use the switch on the ratchet head to change direction as needed for loosening or tightening.

4. การบำรุงรักษาและการจัดเก็บ

Proper maintenance and storage are essential to preserve the accuracy and lifespan of your torque wrench.

• ทำความสะอาดหลังการใช้งาน: Wipe the wrench clean with a dry, soft cloth after each use. Avoid using solvents or harsh chemicals that could damage the finish or internal components.
• Reset to Lowest Setting: Before storing, always reset the torque wrench to its lowest torque setting (20 in-lb or 2.3 N.m). This relieves tension on the internal spring mechanism, preventing fatigue and maintaining calibration accuracy over time. Do not set it below the lowest specified value.
• เก็บในกล่องป้องกัน: Store the torque wrench and its accessories in the provided protective case. This protects it from dust, moisture, and physical damage.
• หลีกเลี่ยงการทำหล่น: Torque wrenches are precision instruments. Dropping the wrench can severely affect its calibration and accuracy.
• การปรับเทียบใหม่: It is recommended to verify the torque wrench's calibration after 12 months or 5000 uses, whichever comes first. Refer to a professional calibration service for this.

5 การแก้ไขปัญหา

หากคุณพบปัญหาเกี่ยวกับประแจวัดแรงบิด โปรดพิจารณาสิ่งต่อไปนี้:

• ไม่มีเสียงคลิก: Ensure the torque value is set correctly and the locking mechanism is engaged. Apply steady, increasing pressure. If still no click, the wrench may require recalibration or inspection.
• Over-tightening/Stripping: This can occur if the torque value is set too high, if pressure is continued after the click, or if the wrench is out of calibration. Double-check the required torque specifications for your fastener and ensure the wrench is properly calibrated.
• การอ่านค่าที่ไม่ถูกต้อง: Inaccurate readings can result from improper storage (not resetting to lowest setting), dropping the tool, or prolonged use without recalibration. If accuracy is critical, professional recalibration is advised.
