Key Features

• Titanium Coating Bottom: The tamper base features a durable titanium coating, which helps prevent static electricity and reduces coffee powder residue, making cleaning easier.
• Three-Spring Design: An original three-spring mechanism ensures a consistent 30lbs of tamping pressure and provides distinct sound feedback upon reaching the target pressure.
• Sound Feedback: A solid "click" indicates when 30lbs of pressure has been applied, eliminating guesswork and ensuring consistent tamping.
• Ergonomic Handle: The handle is designed for comfortable grip and precise control during tamping, combining wood and metal for an elegant finish.
• 53.35mm Base Diameter: Specifically sized to fit 54mm portafilters, such as those found in Breville/Sage coffee machines (Barista Express, Pro, Touch, Bambino Plus, Infuser, Duo-Temp Pro), minimizing residual powder around the basket edge.

Operating Instructions

1. Prepare Coffee Grounds: Fill your 54mm portafilter basket with freshly ground espresso coffee. Ensure the grounds are evenly distributed.
2. Position the Tamper: Place the MHW-3BOMBER tamper squarely on top of the coffee grounds in the portafilter.
3. Apply Pressure: Press down firmly and evenly on the tamper handle. Continue pressing until you hear a distinct "click" sound. This indicates that the consistent 30lbs of pressure has been achieved.
4. Release and Remove: Release pressure and lift the tamper straight up from the portafilter. The tamper features an automatic rebound design and self-adaptive height for consistent tamping depth (approximately 15mm).

Maintenance

To ensure the longevity and optimal performance of your tamper, follow these maintenance guidelines:

• Cleaning: The titanium coating on the base helps reduce coffee residue. Wipe the tamper base with a clean, damp cloth after each use. Avoid harsh abrasives.
• Disassembly for Cleaning/Spring Replacement: The tamper can be disassembled for thorough cleaning or spring replacement.
1. Disassemble components from right to left sequentially.
2. Remove the internal pin.
3. After replacing the spring, install components from right to left sequentially.
4. Install the internal pin.
5. Install components from right to left sequentially.
6. Installation is complete and ready for pressure testing.
• General Care: Do not disassemble the product by yourself unless following the provided guide for spring replacement. Do not wash the entire unit under running water or immerse it. This powder hammer is a precision apparatus; please do not knock it down.

Troubleshooting

If you experience issues with your espresso extraction, consider the following:

• Inconsistent Extraction: Ensure you are pressing the tamper until the audible "click" is heard to guarantee consistent 30lbs pressure. Also, verify that your coffee grounds are evenly distributed before tamping.
• Residual Coffee Powder: The titanium coating is designed to minimize residue. If excessive powder remains, ensure the tamper base is clean and free of obstructions.
• Tamper Mechanism: If the spring mechanism feels unusual or the click is not consistent, refer to the spring replacement guide in the Maintenance section.
