YEH-120L 120mm Professionelle Einzelportions-Kaffeemühle

The YEH-120L features an ultra-precise stepless adjustment dial.

Turn the dial clockwise (toward the right) for a coarser grind (e.g., Pour-over, Cold Brew).

Turn the dial counter-clockwise (toward the left) for a finer grind (e.g., Espresso, Turkish coffee).

Note: Please ensure the motor is running when adjusting to a finer setting if there are beans inside the grinding chamber, to prevent the burrs from locking.

A full deep clean is recommended every 15 days. Unplug first, detach the powder spout and hopper, unscrew the 4 top bolts with the included hex key, and lift the upper section to expose the burrs. Clean with the included brush or a small vacuum. Wipe mating surfaces before reassembling.

The YEH-120L includes an anti-static design to help reduce static during grinding. However, very dry environments, light-roasted coffee, and low ambient humidity can still cause some static or chaff.

Keep the chute and grinding chamber clean and use the press-blow hopper after grinding to help maintain a cleaner single-dose workflow.

No. Thanks to our patented quick-leveling and independent spindle design, the grinder automatically snaps back into its factory micron-level alignment upon reassembly. You only need to remove 3 screws to detach the components for cleaning, and once reassembled, the zero point and alignment remain perfectly locked—no tedious manual calibration required.

If the grinder stops due to extra-hard beans or an overly fine setting:

Immediately turn off the power switch and unplug the machine.

Turn the adjustment dial clockwise to a coarser setting.

Plug it back in, turn it on, and let the motor clear the remaining grounds.

If it remains jammed, follow the manual instructions to safely remove the upper burr carrier and clear the blockage.

Daily Cleaning: Use the included press-to-blow bean hopper (bellows) at the end of your grinding cycle to purge any residual loose grounds. Clean the powder chute with the provided brush.

Deep Cleaning: Remove the four screws to access the burr chamber. Use a brush or dry cloth to clean the burrs and grinding chamber.

CRITICAL SAFETY NOTE: Never wash any part of the grinder body, chamber, or burrs with water. Water will damage the precision bearings, rust the steel components, and pose a severe electrical hazard.

Yes. The YEH-120L is engineered with a highly versatile carrier that natively supports standard 120mm flat burrs, including both blind burrs (screwless surface) and traditional screw-hole configurations (such as standard Lebrew 120, SSP 120HU, or SSP 120LS).

Although the grinder features built-in anti-static engineering, ambient humidity and bean roast levels can still cause static. We highly recommend using the RDT (Ross Droplet Technique): slightly misting your coffee beans with a single drop of water or using a damp stir stick before grinding will completely eliminate static and flying chaff.

Yes. The YEH-120L is designed for professional single-dose workflows in specialty coffee shops, coffee labs, roasting facilities, tasting rooms, and premium coffee bars.

It is best suited to environments that weigh individual doses, switch coffees frequently, or develop recipes rather than high-volume hopper-based batch grinding.
