2. Product Features
- Split Cast Iron Head: Provides a secure housing for interchangeable faces and handles.

- Robust Design: Engineered for long-lasting performance.
3. Setup and Assembly
The Thor RH275 hammer features a patented split-head design that enables the quick replacement of striking faces and handles. This flexibility allows you to customize the hammer for different applications or replace worn components.
Changing Striking Faces or Handle:
- Identify Fasteners: The malleable-iron head is secured by two socket head cap screws. These screws apply uniform clamping pressure to hold the faces and handle in place.
- Loosen Screws: Using an appropriate hex key (not included), carefully loosen the two socket head cap screws on the side of the hammer head. Do not remove them completely unless necessary.
- Remove Components: Once the screws are sufficiently loosened, the existing striking faces and/or the handle can be carefully removed from the split head.
- Insert New Components: Position the new striking faces (e.g., rawhide, super plastic, or nylon, sold separately) and/or the new handle into the head. Ensure they are seated correctly and fully engaged.
- Tighten Screws: Gradually tighten the two socket head cap screws, alternating between them, until the faces and handle are securely clamped. Do not overtighten, as this can damage the components. Ensure the faces are flush and stable.

4. Operating Instructions
Proper operation ensures both effectiveness and safety when using your Thor RH275 hammer.
General Use Guidelines:
- Select Correct Face: Use the rawhide face for tasks requiring a softer impact that will not mar surfaces or generate sparks. For harder impacts or different material requirements, consider purchasing and installing alternative faces (e.g., super plastic, nylon).
- Secure Workpiece: Always ensure the item you are striking is stable and securely held to prevent movement or injury.
- Proper Grip: Hold the hammer firmly with a comfortable grip, ensuring good control.
- Controlled Strikes: Deliver strikes with controlled force. Avoid excessive force that could damage the workpiece, the hammer, or cause injury.
- Eye Protection: Always wear appropriate eye protection when using any striking tool to guard against flying debris.
- Inspect Before Use: Before each use, inspect the hammer head, faces, and handle for any signs of damage, cracks, or looseness. Do not use a damaged hammer.
5. Maintenance
Regular maintenance will prolong the life of your Thor RH275 hammer and ensure its continued safe operation.
- Cleanliness: After each use, wipe down the hammer to remove any dirt, grease, or debris.
- Inspect Faces: Regularly check the rawhide faces for wear, flattening, or damage. Rotate faces for uniform wear or replace them when they become excessively worn.
- Handle Care: The wooden handle should be kept clean and dry. Avoid prolonged exposure to moisture, which can cause the wood to swell or crack. Periodically, a light application of linseed oil can help preserve the wood.
- Head Fasteners: Periodically check the tightness of the socket head cap screws on the split head. Retighten if any looseness is detected.
- Storage: Store the hammer in a dry environment, away from extreme temperatures and direct sunlight, to prevent material degradation.
6. Troubleshooting
Most issues with the Thor RH275 hammer can be resolved through proper inspection and maintenance.
- Loose Striking Face/Handle: If a striking face or the handle feels loose, check the two socket head cap screws on the head and tighten them securely.
- Damaged Striking Face: If a rawhide face is severely worn, cracked, or no longer providing the desired impact, it should be replaced with a new Thor-approved face.
- Damaged Handle: A cracked or splintered wooden handle should be replaced immediately to ensure safe operation.
If you encounter issues not covered here, or if the hammer appears to be structurally compromised, discontinue use and contact Thor customer support.
