3. Safety Information

Always prioritize safety when using hand tools. Failure to follow these safety guidelines may result in injury or damage to the tool.

• Wear Eye Protection: Always wear ANSI-approved safety glasses or goggles to protect against flying debris.
• Inspect Before Use: Before each use, inspect the hammer for any signs of damage, such as cracks in the head or handle, or excessive wear. Do not use a damaged hammer.
• Proper Grip: Maintain a firm, comfortable grip on the handle.
• Strike Squarely: Always strike the nail head or work surface squarely. Angled strikes can cause the hammer to glance off, leading to injury or damage.
• Use for Intended Purpose: This hammer is designed for driving and pulling nails in wood. Do not use it for striking hardened steel objects, prying, or as a wedge.
• Keep Work Area Clear: Ensure your work area is free of obstructions and bystanders.

4. Setup

The Stanley FatMax Xtreme Hi-Velocity Curve Claw Framing Hammer is ready for immediate use out of its packaging. No assembly or special setup is required.

1. Remove the hammer from its packaging.
2. Perform a visual inspection for any shipping damage or manufacturing defects.
3. Ensure the handle is securely attached to the head (though this model is a single-piece steel construction, a general check is good practice).

5. Operating Instructions

5.1 Driving Nails

1. Positioning: Hold the nail between your thumb and forefinger, placing it on the desired surface.
2. Initial Taps: Using the hammer's magnetic nail starter or a light tap, set the nail into the material just enough for it to stand on its own. Ensure the hammer face is square to the nail head.
3. Full Swings: Once the nail is stable, remove your hand. Take a controlled swing, striking the nail head squarely with the hammer face. Use your arm and shoulder for power, not just your wrist.
4. Finishing: Continue striking until the nail is flush with or slightly below the surface.

5.2 Removing Nails (Claw Use)

1. Position Claw: Slide the curved claw under the head of the nail. Ensure the nail head is fully seated within the claw's V-notch.
2. Leverage: Apply downward pressure on the hammer handle, using the curved head as a fulcrum to lever the nail out of the material.
3. Stubborn Nails: For nails that are difficult to remove, place a small block of wood under the hammer head to increase leverage and protect the work surface from damage.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your Stanley hammer.

• Cleaning: After each use, wipe down the hammer head and handle with a clean, dry cloth to remove dirt, dust, and debris. For stubborn grime, a damp cloth can be used, followed by thorough drying.
• Storage: Store the hammer in a dry environment to prevent rust. Avoid storing it in areas with high humidity or extreme temperature fluctuations.
• Inspection: Periodically inspect the hammer for any signs of wear, such as dulling of the strike face, damage to the claw, or degradation of the handle grip. While this hammer is 100% steel, ensuring the grip remains intact is important for safety.
• Rust Prevention: If storing for extended periods, a light coat of machine oil on the metal parts can help prevent rust.

7. Troubleshooting

Most issues with a hammer are related to technique or wear. Here are some common points:

• Nails Bending: This often indicates an off-center strike or insufficient force. Ensure you are striking the nail head squarely and with adequate, controlled force. Practice improves accuracy.
• Hammer Glancing Off: This can occur if the strike face is not parallel to the nail head at impact. Focus on a straight, controlled swing.
• Difficulty Pulling Nails: Ensure the nail head is fully seated in the claw. For very long or stubborn nails, use a wooden block under the hammer head for increased leverage.
• Excessive Wear on Strike Face/Claw: If the hammer face or claw shows significant chipping, mushrooming, or dulling, it may be due to striking hardened materials or improper use. Replace the hammer if it becomes unsafe or ineffective.
