2. Safety Information

Always observe the following safety precautions when using the ENGINEER NS-04 nippers to prevent injury and tool damage:

• Wear Eye Protection: Always wear safety glasses or goggles to protect your eyes from flying debris during cutting operations.
• Intended Use: These nippers are designed for cutting soft materials such as copper wire, electronic component leads, and plastic. Do not use them for cutting hard materials like steel wire, piano wire, or screws, as this can damage the cutting edges.
• Proper Grip: Maintain a firm and secure grip on the handles during use.
• Keep Fingers Clear: Ensure fingers and other body parts are clear of the cutting jaws.
• Storage: Store the nippers in a dry, safe place, out of reach of children.
• Inspection: Before each use, inspect the nippers for any signs of damage, such as chipped jaws or loose handles. Do not use damaged tools.

3. Product Features

The ENGINEER NS-04 nippers incorporate several design elements for precision and durability:

• Compact Size: Ideal for precise work in confined spaces, such as PCB assembly, electronics repair, and intricate craft projects.
• Flush Cutting Edges: Specially designed for clean, flush cuts on electronic components, copper wire, and soft lead wires, minimizing protrusions.
• Hardened Carbon Steel Jaws: Constructed from heat-treated carbon steel for exceptional cutting performance and extended durability.
• Angle Opening Adjuster: A mechanism that allows adjustment of the maximum jaw opening when the grips are released. This feature enhances productivity and reduces hand fatigue during repetitive cutting tasks.
• ESD Safe Comfort Grips: Handles made from oil-resistant thermoplastic elastomer, providing a comfortable and secure grip while offering electrostatic discharge (ESD) protection.

4. Setup and Initial Inspection

The ENGINEER NS-04 nippers are ready for use directly out of the packaging. No assembly is required.

1. Unpack: Carefully remove the nippers from their packaging.
2. Visual Inspection: Examine the nippers for any visible damage that may have occurred during shipping. Check the cutting edges for chips or misalignment.
3. Functionality Check: Open and close the handles a few times to ensure smooth operation and proper spring action. Verify that the jaw opening adjuster functions correctly.

5. Operating Instructions

Follow these steps for effective and safe use of your nippers:

1. Identify Material: Ensure the material to be cut is within the nippers' capacity (soft copper wire, plastic, component leads). Avoid hard materials.
2. Positioning: Place the material as deep as possible into the jaws for optimal leverage and a clean cut. For flush cuts, position the flat side of the nipper jaws against the surface from which you are cutting.
3. Cutting Action: Apply steady, firm pressure to the handles until the cut is complete. Avoid twisting or prying with the nippers.
4. Jaw Opening Adjustment: To adjust the maximum opening of the jaws, locate the small screw mechanism between the handles near the pivot point (refer to Image 2). Loosen the screw slightly, set the desired maximum opening, and then tighten the screw to secure the setting. This is useful for repetitive tasks to reduce hand movement.

6. Maintenance and Care

Proper maintenance ensures the longevity and performance of your nippers:

• Cleaning: After each use, wipe the nippers clean with a dry, soft cloth to remove any debris or residue.
• Lubrication: Periodically apply a small drop of light machine oil to the pivot point to maintain smooth operation. Wipe off any excess oil.
• Storage: Store the nippers in a protective pouch or tool tray to prevent damage to the cutting edges. Keep them in a dry environment to prevent rust.
• Avoid Dropping: Dropping the nippers, especially on hard surfaces, can damage the precision-ground cutting edges.

7. Troubleshooting

If you encounter issues with your nippers, consider the following:

• Stiff Operation: If the nippers feel stiff, apply a small amount of light machine oil to the pivot point and work the handles to distribute the lubricant.
• Poor Cutting Performance: Ensure you are cutting appropriate materials. If the cutting edges appear dull or damaged, the nippers may require professional sharpening or replacement. Do not attempt to sharpen the precision edges yourself unless you have specialized tools and expertise.
• Jaws Not Closing Completely: Check for any debris lodged between the jaws or at the pivot point. Clean thoroughly. If the issue persists, the tool may be damaged.
