Setup
The STANLEY FATMAX Brick Bolster is a ready-to-use hand tool and requires minimal setup. Ensure the tool is clean and free from any debris before use.
- Inspection: Before each use, inspect the bolster for any signs of damage, such as cracks in the handle or chips in the blade. Do not use if damaged.
- Safety Gear: Always wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and sturdy footwear, when using the brick bolster.
- Work Area: Ensure your work area is clear of obstructions and that you have stable footing.
Operating Instructions
Follow these steps for effective and safe operation of your brick bolster:
- Marking: Clearly mark the line where you intend to cut or shape the brick or block.
- Positioning: Place the blade of the bolster firmly on the marked line. Ensure the bolster is held perpendicular to the surface of the material.
- Striking: Using a mallet or a small sledgehammer, strike the top of the bolster's striking cap. Apply firm, controlled blows. The protective hand guard helps shield your hand from misdirected strikes.
- Cutting: Continue striking until the brick or block cleanly separates along the desired line. For precise cuts, you may need to score the material first or make multiple lighter strikes.
- Clean Cut: The design of the bolster allows for a clean cut, making it ideal for interlocking bricks and other masonry applications.
Important Considerations:
- Always strike the bolster squarely to prevent damage to the tool and ensure an effective cut.
- Avoid striking the bolster with excessive force that could cause the material to shatter or the tool to slip.
- Do not use the bolster for prying or as a lever, as this can damage the blade or handle.

Maintenance
Proper maintenance will extend the life of your STANLEY FATMAX Brick Bolster:
- Cleaning: After each use, clean the blade and handle to remove any dust, mortar, or debris. A wire brush can be used for stubborn residue on the blade.
- Rust Prevention: Apply a light coat of oil to the steel blade after cleaning, especially if storing for extended periods or in humid conditions, to prevent rust.
- Storage: Store the bolster in a dry place, away from moisture and corrosive materials. Keep it out of reach of children.
- Sharpening: If the blade becomes dull over time, it can be sharpened using a suitable grinding wheel or file. Maintain the original blade angle for optimal performance.
Troubleshooting
Here are some common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Blade not cutting cleanly. | Dull blade; incorrect striking angle. | Sharpen the blade; ensure the bolster is held perpendicular to the material. |
| Material shattering instead of cutting. | Excessive force; material too brittle. | Use lighter, more controlled strikes; consider scoring the material first. |
| Bolster slipping during use. | Unstable work surface; improper grip. | Ensure a stable work surface; maintain a firm grip on the handle. |
