2. Setup
The Blackhawk by Proto PT-1287 External Retaining Ring Plier is a ready-to-use hand tool and requires no assembly. Before first use, inspect the pliers for any signs of damage or manufacturing defects. Ensure the tips are aligned and the pivot mechanism operates smoothly.
Safety Precautions:
- Always wear appropriate personal protective equipment (PPE), such as safety glasses, when working with retaining rings, as they can spring off unexpectedly.
- Ensure the work area is well-lit and clear of obstructions.
- Do not use the pliers for purposes other than those for which they are designed.
3. Operating Instructions
These pliers are specifically designed for installing and removing external retaining rings. External retaining rings fit into a groove on the outside of a shaft or housing.
- Identify the Retaining Ring: Confirm that the retaining ring is an external type, designed to be expanded for removal or installation.
- Position the Pliers: Insert the tips of the pliers into the holes (lugs) on the retaining ring.
- Expand the Ring: Gently squeeze the handles of the pliers. This action will cause the tips to spread apart, expanding the retaining ring. The no-pinch release mechanism ensures a smooth operation.
- Remove/Install:
- For Removal: Once the ring is sufficiently expanded, carefully lift it out of its groove.
- For Installation: Position the expanded ring over the shaft or into the housing groove, then release the plier handles to allow the ring to contract and seat securely.
- Verify Seating: After installation, ensure the retaining ring is fully seated in its groove.

4. Maintenance
Proper maintenance will extend the life of your Blackhawk by Proto PT-1287 pliers.
- Cleaning: After each use, wipe the pliers clean with a dry cloth to remove any dirt, grease, or debris. 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.
- Storage: Store the pliers in a dry environment to prevent corrosion. Keep them away from excessive moisture and extreme temperatures.
- Inspection: Regularly inspect the plier tips for wear or damage. If the tips become bent or misaligned, the pliers may not function effectively and could damage retaining rings.
