Pittsburgh Pro 239 Professional Drive Click Stop Torque Wrench

การแนะนำ

The Pittsburgh Pro 239 Professional Drive Click Stop Torque Wrench is a precision instrument designed for applying specific torque values to fasteners. This tool is essential for applications where accurate tightening is critical to prevent damage to components or ensure proper assembly. It features a heavy-duty cam and pawl mechanism, offering reliable and accurate torque application within its specified range.

ข้อมูลด้านความปลอดภัย

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

• สวมอุปกรณ์ป้องกันดวงตา: ควรสวมแว่นตานิรภัยที่ได้รับการรับรองมาตรฐาน ANSI หรือหน้ากากป้องกันใบหน้าทุกครั้งเมื่อใช้งานเครื่องมือ
• การใช้งานที่เหมาะสม: Use the torque wrench only for its intended purpose of applying specific torque to fasteners. Do not use it as a breaker bar or for loosening fasteners.
• Do Not Exceed Capacity: Never exceed the maximum torque capacity of 150 ft. lbs. Doing so can damage the tool and lead to injury.
• รักษาความสะอาด: Keep the wrench clean and free from oil, grease, or other contaminants that could affect its accuracy or your grip.
• พื้นที่จัดเก็บ: Store the torque wrench in its protective case and set to the lowest torque setting (but not below the minimum) when not in use to relieve spring tension and maintain calibration.
• การสอบเทียบ: Torque wrenches are precision instruments and should be periodically checked for calibration by a qualified technician.

ส่วนประกอบและคุณสมบัติ

The Pittsburgh Pro 239 Torque Wrench is a 1/2" drive click-type wrench with a reversible head. Key features include:

• ขนาดไดรฟ์: 1/2 inch square drive.
• แรงบิดช่วง: 20 to 150 ft. lbs.
• ความแม่นยำ: Accurate to within +/- 4%.
• กลไก: Heavy-duty cam and pawl mechanism for reliable clicking.
• Reversible Head: Allows for tightening in both clockwise and counter-clockwise directions, though torque measurement is typically for clockwise tightening.
• วัสดุ: Constructed from durable Alloy Steel.
• ความยาว: Approximately 18 inches (45.72 cm).

การตั้งค่า

1. แกะ: นำประแจวัดแรงบิดออกจากบรรจุภัณฑ์และกล่องป้องกันอย่างระมัดระวัง
2. ตรวจสอบ: Before each use, inspect the wrench for any signs of damage, wear, or foreign debris. Ensure the drive head moves freely and the adjustment mechanism operates smoothly.
3. ทำความสะอาด: Wipe down the wrench with a clean, dry cloth if necessary.
4. เชื่อมต่อซ็อกเก็ต: Select the appropriate 1/2-inch drive socket for your fastener and firmly attach it to the square drive head of the wrench.

คำแนะนำการใช้งาน

1. ตั้งค่าแรงบิด:
   • Locate the locking knob at the end of the handle. Pull it down to unlock the adjustment mechanism.
   • Rotate the handle to align the desired torque value on the main scale with the zero mark on the thimble scale.
   • For intermediate values, continue rotating the handle until the desired increment on the thimble scale aligns with the main scale line.
   • Push the locking knob back up to secure the setting. Ensure it is fully engaged to prevent accidental changes during use.
2. ใช้แรงบิด:
   • วางซ็อกเก็ตลงบนตัวยึด
   • Apply smooth, steady pressure to the handle in a clockwise direction (for standard right-hand threads) until you feel and hear a distinct "click" from the wrench. This click indicates that the preset torque value has been reached.
   • บันทึก: Do not continue to apply force after the click. Over-tightening can damage the fastener or component.
3. Reversing the Drive: The wrench head is reversible. To change the direction of the drive, simply flip the small lever on the wrench head. While the wrench can operate in both directions, its accuracy for torque measurement is typically specified for clockwise tightening.
4. Reset After Use: After each use, rotate the handle to set the torque wrench to its lowest setting (20 ft. lbs.) before storing. This relieves tension on the internal spring and helps maintain the wrench's calibration over time.

การซ่อมบำรุง

• การทำความสะอาด: Wipe the wrench clean with a dry, lint-free cloth after each use. Do not use solvents or harsh chemicals, as they may damage the finish or internal components.
• พื้นที่จัดเก็บ: Store the torque wrench in its original protective case in a clean, dry environment. Always set the wrench to its lowest torque setting (20 ft. lbs.) before storage to preserve the spring's integrity.
• การหล่อลื่น: The internal mechanism is factory lubricated and generally does not require user lubrication. If the mechanism feels stiff or sticky, consult a professional for service.
• การสอบเทียบ: For professional or critical applications, it is recommended to have the torque wrench calibrated annually or after approximately 2,500 cycles, whichever comes first.
