Setup
The Blackhawk By Proto PT-1248-2 Rib Lock Plier is ready for immediate use upon unboxing. No assembly is required.
- Unpack: Carefully remove the plier from its packaging.
- Inspect: Before first use, visually inspect the plier for any signs of damage, such as bent jaws, loose handles, or corrosion. Ensure the pivot mechanism moves freely.
- Clean (Optional): If desired, wipe down the plier with a clean, dry cloth to remove any manufacturing residues or dust.
Operating Instructions
These pliers are designed for gripping, holding, and turning various shapes of objects, including pipes, nuts, and bolts. The rib lock design allows for quick and secure jaw adjustments.
- Adjusting Jaw Opening:
- Open the plier handles fully.
- Slide the upper jaw along the ribbed track on the lower handle to adjust the jaw opening. Select a rib position that allows the jaws to comfortably fit around the object you intend to grip.
- Ensure the jaws are parallel and make full contact with the object for optimal grip.
- Gripping an Object:
- Position the jaws around the object.
- Squeeze the handles together firmly to secure the grip. The overmolded cushion grips provide comfort and reduce hand fatigue.
- Apply necessary force to turn or hold the object.
- Releasing the Grip:
- Loosen your grip on the handles. The no-pinch release mechanism is designed to prevent accidental pinching during release.
- Remove the plier from the object.
Safety Precaution:
- Always wear appropriate personal protective equipment, such as safety glasses, when using hand tools.
- Do not use pliers as a hammer or pry bar.
- Do not extend the handle length with pipes or other objects, as this can damage the tool or cause injury.
Maintenance
Proper maintenance will extend the life of your Blackhawk By Proto Rib Lock Plier.
- Cleaning: After each use, wipe down the plier with a clean, dry cloth to remove dirt, grease, or moisture. For stubborn grime, a mild degreaser can be used, followed by thorough drying.
- Lubrication: Periodically apply a small amount of light machine oil to the pivot point to ensure smooth operation and prevent rust. Wipe off any excess oil.
- Storage: Store the plier in a dry environment to prevent corrosion. Avoid storing in damp or humid conditions.
- Inspection: Regularly inspect the jaws for wear or damage. If the gripping teeth become excessively worn, the plier's effectiveness may be reduced.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Jaws are stiff or difficult to open/close. | Lack of lubrication at the pivot point; dirt or debris in the mechanism. | Clean the pivot area thoroughly and apply a few drops of light machine oil. Work the handles to distribute the oil. |
| Poor grip on objects. | Incorrect jaw adjustment; worn jaw teeth; object is too large or small for the plier. | Ensure the jaws are adjusted correctly to the object's size. Inspect jaw teeth for wear. Use the correct size tool for the task. |
| Rust appearing on metal surfaces. | Exposure to moisture or humidity; improper storage. | Clean off rust with a wire brush or fine abrasive, then apply a rust-inhibiting oil. Store in a dry environment. |
