Operating Instructions
Follow these steps for consistent and effective coffee tamping:
- Dose and Distribute: After dosing your ground coffee into the portafilter basket, ensure an even distribution of the coffee grounds.
- Position the Tamper: Place the MHW-3BOMBER tamper squarely on top of the coffee grounds in the portafilter. The horizontal spring system helps prevent tilting, ensuring a level tamp.
- Apply Pressure: Press down firmly on the tamper. The internal impact spring will apply consistent pressure. Continue pressing until you hear a distinct "click" sound. This audible feedback indicates that the preset tamping pressure has been achieved.

The tamper's design ensures that it automatically adapts to the height of the coffee grounds, requiring no manual adjustment for depth. The maximum tamping depth is 13mm.

Maintenance
- Cleaning: After each use, wipe the tamper base with a clean, damp cloth to remove any coffee residues. Ensure the tamper is completely dry before storage.
- Do Not Dishwash: This tamper is not dishwasher safe. Hand wash only.
- Storage: Store the tamper in a dry place away from direct sunlight and extreme temperatures to preserve its materials and functionality.
- Material Care: The robust aluminum alloy construction is designed for anti-corrosion and anti-oxidation. Avoid abrasive cleaners or tools that could scratch the surface.
Troubleshooting
- Inconsistent Tamping: Ensure the coffee grounds are evenly distributed in the portafilter before tamping. Apply steady, downward pressure until the audible "click" is heard.
- No "Click" Sound: Verify that sufficient pressure is being applied. The tamper requires a certain force to trigger the sound feedback mechanism. If the issue persists, ensure no debris is obstructing the internal spring mechanism.
- Tamper Not Level: The horizontal spring system is designed to prevent tilting. Ensure you are placing the tamper straight down onto the coffee bed. If the issue persists, check for any damage to the tamper's base or internal structure.
