5. Operating Instructions
These diagonal cutting pliers are designed for efficient and precise cutting of various materials, primarily wires and soft metals. Follow these steps for optimal use:
- Grip: Hold the pliers firmly in your dominant hand, ensuring a secure and comfortable grip on the red plastic-dipped handles.
- Position Material: Place the material to be cut as far back into the jaws as possible. This utilizes the high-leverage design for maximum cutting force.
- Apply Pressure: Squeeze the handles together with steady, firm pressure until the material is cleanly cut. Avoid twisting the pliers during the cut.
- Material Compatibility: These pliers are ideal for cutting copper, aluminum, and soft steel wires. Do not attempt to cut hardened steel, screws, or other materials beyond the tool's capacity, as this can damage the cutting edges.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Klein Tools D228-8 pliers:
- Cleaning: After each use, wipe the pliers clean with a dry cloth to remove dirt, dust, or debris. For stubborn grime, a mild solvent can be used, followed by thorough drying.
- Lubrication: Periodically apply a few drops of light machine oil to the pivot joint. Open and close the pliers several times to distribute the oil evenly. This helps maintain smooth action and prevents rust.
- Storage: Store the pliers in a dry environment to prevent rust. Keep them away from corrosive materials.
- Edge Care: Avoid dropping the pliers or using them to cut materials harder than their intended capacity, as this can chip or dull the cutting edges. Sharpening of the induction hardened edges is generally not recommended and may void warranty.
7. Troubleshooting
Common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Jaws feel stiff or sticky. | Lack of lubrication; dirt/debris in joint. | Clean the pivot joint thoroughly and apply light machine oil. Work the joint to distribute the oil. |
| Cutting edges appear dull or chipped. | Attempting to cut materials beyond capacity; accidental dropping. | Avoid cutting hardened materials. If severely damaged, the tool may need replacement. |
| Handles feel loose or wobble. | Wear and tear on the hot-riveted joint (uncommon for Klein Tools). | If the wobble is significant and affects performance, contact Klein Tools customer support for assistance. |
| Rust formation on metal parts. | Exposure to moisture; improper storage. | Clean off rust with a wire brush or fine abrasive, then apply a rust-preventative oil. Store in a dry place. |
