3. Setup and Adjustment
Before first use, familiarize yourself with the adjustment mechanisms of the Distributor Duo.
3.1 Adjusting Distribution Depth
The depth of the leveling blades can be adjusted to suit your portafilter and desired coffee dose. Locate the adjustment ring on the base of the tool. Rotate this ring to raise or lower the blades. A scale is typically marked on the side to assist with consistent depth settings.

3.2 Configuring WDT Pins
The WDT pins can be configured for either an angled or straight arrangement based on your preference for breaking up coffee clumps. Gently pull or push the pins to adjust their orientation within the assembly. Ensure all pins are securely in place before use.

4. Operation
Follow these steps for optimal espresso puck preparation:
- Grind Coffee: Grind your fresh coffee beans directly into your 54mm portafilter basket. Ensure the basket is filled with enough coffee for your desired dose.
- WDT (Clump Breaking): Place the WDT pin assembly over the portafilter. Gently rotate the tool to allow the pins to break up any clumps in the coffee grounds. This helps to eliminate channeling during extraction.
- Leveling: Flip the tool to engage the angled distribution blades. Place the tool onto the portafilter basket, ensuring it rests evenly on the rim. Rotate the tool clockwise several times to evenly distribute and level the coffee grounds. The adjustable blades will ensure a flat surface.
- Tamp: After distribution and leveling, proceed with tamping your coffee grounds using a separate tamper.

5. Maintenance and Care
Proper care will ensure the longevity and performance of your Distributor Duo.
- Cleaning: After each use, gently wipe the stainless steel base and WDT pins with a soft, damp cloth to remove any coffee residue. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
- Walnut Handle Care: The walnut handle should be wiped clean with a dry or slightly damp cloth. Do not submerge the handle in water or place it in a dishwasher, as this can damage the wood. Periodically, a food-safe wood conditioner can be applied to maintain the wood's appearance.
- Storage: Store the tool in a dry place away from direct sunlight and extreme temperatures.
- WDT Wire Replacement: If any WDT wires become bent or damaged, carefully remove them and replace with the provided spare wires.
6. Troubleshooting
If you encounter issues with your Distributor Duo, consider the following:
- Uneven Distribution: Ensure the tool's depth is correctly set for your portafilter and coffee dose. Rotate the tool slowly and consistently during the leveling process. Check your coffee grind consistency; an inconsistent grind can lead to uneven distribution.
- WDT Pins Not Effective: Ensure the pins are clean and free of coffee buildup. Adjust the pin configuration if necessary to better break up clumps.
- Tool Sticking: If the tool feels sticky or difficult to rotate, ensure it is clean and free of coffee oils. A light wipe with a damp cloth should resolve this.
