คำแนะนำการใช้งาน
The Armstrong 12-849 Crowfoot Flare Nut Wrench is designed for specific applications where traditional wrenches cannot reach or properly engage flare nuts.
- Identify Target Fastener: Locate the 1-11/16-inch flare nut that needs to be tightened or loosened.
- วางประแจในตำแหน่งที่เหมาะสม: Carefully slide the open end of the crowfoot wrench over the flare nut. Ensure the wrench fully engages all sides of the nut to prevent slippage and damage.
- ใช้แรง: Using your attached drive tool, apply steady and controlled force to turn the flare nut. For tightening, refer to the manufacturer's torque specifications for the component you are working on.
- หลีกเลี่ยงการขันแน่นเกินไป: Flare nuts, especially on hydraulic or fuel lines, can be sensitive. Over-tightening can damage the nut or the line.
- Remove Wrench: Once the task is complete, carefully remove the crowfoot wrench from the flare nut and then detach it from the drive tool.
การซ่อมบำรุง
- การทำความสะอาด: After each use, wipe the wrench clean with a dry cloth to remove any dirt, grease, or debris. For stubborn grime, a mild solvent can be used, followed by thorough drying.
- พื้นที่จัดเก็บ: Store the wrench in a dry environment to prevent corrosion. A tool chest or drawer is ideal.
- การตรวจสอบ: Periodically inspect the wrench for any signs of wear, cracks, or damage. Discontinue use if any damage is found that could compromise its integrity or safety.
การแก้ไขปัญหา
- Wrench slips on nut: Ensure the wrench size (1-11/16 inch) matches the flare nut exactly. Confirm the wrench is fully seated on the nut before applying force. The nut may be severely rounded; consider using a specialized nut extractor if necessary.
- Difficulty attaching to drive tool: Check that the drive tool is a 1/2-inch square drive. Ensure there is no debris in the crowfoot wrench's drive opening.
- Nut still hard to turn: For seized nuts, apply penetrating oil and allow it to soak. Ensure you are applying sufficient, but not excessive, leverage.
