5. Instruccions de funcionament
This plier set can be configured for both internal and external snap rings.
5.1. For External Snap Rings (Spreading Action)
External snap rings are designed to fit into a groove on the outside of a shaft or pin. To remove or install them, the pliers need to spread the ring open.
- Configure Pliers: Ensure the jaw tips are positioned to spread apart when the handles are squeezed. This is typically achieved by placing the jaw assembly on the outer set of pins on the plier body.
- Position Tips: Insert the tips of the pliers into the holes of the external snap ring.
- Spread Ring: Slowly and carefully squeeze the plier handles to spread the snap ring open.
- Remove/Install: Once the ring is sufficiently spread, carefully remove it from or install it onto the shaft. Release the handles slowly.

5.2. For Internal Snap Rings (Compressing Action)
Internal snap rings are designed to fit into a groove inside a bore or housing. To remove or install them, the pliers need to compress the ring.
- Configure Pliers: Ensure the jaw tips are positioned to close together when the handles are squeezed. This is typically achieved by placing the jaw assembly on the inner set of pins on the plier body.
- Position Tips: Insert the tips of the pliers into the holes of the internal snap ring.
- Compress Ring: Slowly and carefully squeeze the plier handles to compress the snap ring.
- Remove/Install: Once the ring is sufficiently compressed, carefully remove it from or install it into the bore. Release the handles slowly.

Always ensure the snap ring is fully seated in its groove before releasing tension from the pliers.
6. Manteniment
- Neteja: After each use, wipe the pliers and jaw assemblies clean with a dry cloth to remove dirt, grease, or debris.
- Lubricació: Periodically apply a light coat of machine oil to the pivot points of the pliers and jaw assemblies to ensure smooth operation and prevent rust.
- Emmagatzematge: Store the tool set in a dry environment to prevent corrosion. Keep all jaw assemblies together with the plier body to avoid loss.
- Inspecció: Regularly inspect the jaw tips for wear or bending. Replace damaged jaw assemblies if necessary.
7. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Jaw tips do not fit into snap ring holes. | Tips are too large for the snap ring. | Ensure you are using the correct size snap ring pliers for the application. If tips are slightly oversized, careful filing may be an option for experienced users, but this can compromise tool integrity. |
| Jaws feel loose or detach during use. | Pivot pin not fully engaged; spring retainer weak; excessive force applied. | Verify the pivot pin is fully inserted and secured. Apply steady, controlled pressure. If the issue persists, the tool may be defective or worn. |
| Pliers slip off the snap ring. | Incorrect tip angle; tips worn or bent; insufficient grip. | Select the appropriate jaw angle (straight, 45°, 90°). Ensure tips are clean and sharp. Apply firm, even pressure. Replace worn tips. |
| Difficulty spreading/compressing snap ring. | Snap ring is too stiff; pliers are undersized for the task; incorrect plier configuration. | Ensure pliers are configured correctly for internal (compress) or external (spread) rings. Do not force the tool; consider if a heavier-duty plier is required for very stiff rings. |
