2. Safety Guidelines
Always prioritize safety when using hand tools. Adhere to the following guidelines to prevent injury and ensure proper tool function:
- Wear Eye Protection: Always wear safety glasses or goggles to protect your eyes from flying debris.
- Inspect Tools Before Use: Check pliers for any damage, wear, or loose parts. Do not use damaged tools.

3.1. Diagonal Pliers (150 mm)
Also known as side cutters, these pliers feature angled cutting edges designed for cutting wire, small nails, and other soft materials flush with a surface. They are not intended for gripping or turning.
3.2. Combination Pliers (150 mm)
These versatile pliers combine gripping jaws with a cutting edge. The serrated jaws are suitable for gripping and bending various materials, while the integrated cutter can handle wires. They are a general-purpose tool for electrical work, plumbing, and mechanical tasks.
3.3. Long Nose Pliers (150 mm)
Featuring long, tapered jaws, these pliers are ideal for reaching into tight spaces, bending small wires, holding small objects, and performing delicate tasks. Some models include a small cutting edge near the pivot.
3.4. Groove Joint Pliers (250 mm)
Also known as water pump pliers or Channellock pliers, these have adjustable jaws that can be set to various widths, allowing them to grip objects of different sizes. They are commonly used for plumbing tasks, gripping pipes, nuts, and bolts.

Upon receiving your Amazon Basics Pliers Set, perform the following steps:
- Unpack: Carefully remove the pliers set from its packaging.

5. Operating Instructions
Proper use of pliers ensures efficiency and safety. Always refer to the safety guidelines in Section 2.
5.1. General Usage Tips
- Grip Firmly: Hold the plier handles firmly but comfortably.
- Apply Even Pressure: When gripping or cutting, apply steady, even pressure.
- Avoid Side Loads: Do not use pliers to pry or twist excessively, as this can bend the jaws or damage the pivot.
- Clean Work Area: Ensure your work area is clear of obstructions and well-lit.
5.2. Specific Pliers Usage
- Diagonal Pliers: Position the wire or material to be cut between the cutting edges. Squeeze the handles firmly to make a clean cut. Do not use for gripping.
- Combination Pliers: Use the serrated jaw section for gripping and turning nuts, bolts, or pipes. Use the cutting edge for cutting wires.
- Long Nose Pliers: Use the fine tips for bending small loops in wire, retrieving small objects from confined spaces, or holding small components.
- Groove Joint Pliers: Adjust the jaw opening by sliding the pivot pin into the desired groove on the handle. This allows for a wide range of jaw capacities to grip various sizes of pipes or fasteners. Ensure the jaws are parallel to the workpiece for maximum grip.

6. Care and Maintenance
Proper care extends the life and performance of your pliers.
- Cleaning: After each use, wipe down the pliers with a clean, dry cloth to remove dirt, grease, and moisture.
- Lubrication: Periodically apply a small amount of light machine oil to the pivot points to ensure smooth operation and prevent rust. Wipe off any excess oil.
- Storage: Store the pliers in their provided durable nylon case in a dry environment to prevent corrosion. Avoid storing them in damp or humid conditions.
- Rust Prevention: If pliers come into contact with water or corrosive substances, clean and dry them immediately, then apply a rust-inhibiting oil.
7. Troubleshooting
This section addresses common issues you might encounter with your pliers.
7.1. Stiff Joints
If the pliers feel stiff or difficult to open and close, apply a few drops of light machine oil to the pivot joint. Work the pliers open and closed several times to distribute the lubricant, then wipe off any excess.
7.2. Rust Formation
Rust can occur if pliers are exposed to moisture. If minor rust appears, it can often be removed with a wire brush or fine abrasive paper, followed by cleaning and oiling. For significant rust, consider replacement to ensure safety and performance.
7.3. Damaged Jaws or Cutting Edges
If jaws are bent, chipped, or cutting edges are dull or damaged, the pliers may not function effectively or safely. Damaged tools should be replaced. Do not attempt to repair critical tool components yourself.
