Setup and Initial Adjustment

The Cobra QuickSet pliers feature a unique adjustment mechanism. Before first use or when changing workpiece sizes, understand the two primary adjustment methods:

1. Push-Button Adjustment (Standard Cobra Function):

   To adjust the gripping width precisely, press the red button located at the pivot point. While holding the button, slide the jaws open or closed to the desired width. Release the button to lock the jaws in place. This method provides fine adjustment for various sizes.

2. QuickSet Function (Sliding Adjustment):

   For rapid adjustment, especially in confined spaces, the QuickSet function allows you to slide the pliers handle directly onto the workpiece without pressing the button. The hinge bolt will automatically engage with the first workload, fixing the gripping width. To reactivate the sliding function, you must fully open the pliers and then press the red button to release the hinge bolt.

Operating Instructions

The KNIPEX Cobra QuickSet Pliers are designed for secure gripping of various shapes, including round, square, and hexagonal workpieces. Follow these steps for optimal use:

1. Selecting the Gripping Width:

   Choose between the push-button adjustment for precise settings or the QuickSet sliding function for rapid, on-workpiece adjustments. For the QuickSet, simply open the jaws wide enough to fit over the workpiece, then slide the pliers until the jaws engage. The hinge bolt will lock upon initial pressure.

2. Applying Grip:

   Once the jaws are set to the correct size, apply firm pressure to the handles. The specially hardened teeth provide a strong, self-locking grip, preventing slippage even under high torque. This self-locking effect means less hand force is required, reducing fatigue.

3. Reactivating QuickSet:

   If the QuickSet function is locked (i.e., the pliers are only adjustable via the button), fully open the pliers until the jaws are at their widest point. Then, press the red adjustment button. This action resets the hinge bolt, allowing the sliding QuickSet adjustment to be used again.

Maintenance

Proper maintenance ensures the longevity and optimal performance of your KNIPEX Cobra QuickSet Pliers:

• Cleaning: After each use, wipe the pliers clean with a dry cloth to remove dirt, grease, or debris. For stubborn grime, use a mild solvent and ensure the pliers are thoroughly dried afterward.
• Lubrication: Periodically apply a light machine oil to the pivot point and adjustment mechanism to ensure smooth operation. Wipe off any excess oil.
• Storage: Store the pliers in a dry environment to prevent rust. Avoid storing them in damp conditions or where they might be exposed to corrosive chemicals.
• Inspection: Regularly inspect the jaws for wear or damage. Ensure the teeth are sharp and free from obstructions. Check the handles for any signs of damage or loosening.

Troubleshooting

If you encounter issues with your KNIPEX Cobra QuickSet Pliers, consider the following common solutions:

• Pliers not gripping securely:

  Ensure the jaws are properly adjusted to the workpiece size. The self-locking effect relies on correct jaw engagement. Check for excessive wear on the gripping teeth; if severely worn, the pliers may need replacement.
• QuickSet sliding function not working:

  The QuickSet function locks after the first use. To reactivate it, fully open the pliers and then press the red adjustment button. This resets the mechanism, allowing for sliding adjustment again. Ensure the pivot point is clean and lubricated.

• Stiff adjustment button or pivot:

  Clean any accumulated dirt or debris from the pivot area and the adjustment button. Apply a small amount of light machine oil to lubricate these parts. Operate the pliers several times to distribute the lubricant.
