FAQ
What grind settings should I start with?
For espresso with the stock burr, start at dial position 3 and a motor speed of 1000–1500 RPM. For pour over, try 10–11.5 at 200–700 RPM. Light roasts need finer settings; dark roasts need coarser. On first power-on, set the dial to position 30 (not 0) to avoid burr contact.
How often should I clean the grinder?
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.
Can I use 102mm burrs?
Yes. The YEH-98L accepts 102mm flat burrs but requires the separate 102mm burr carrier adapter. 98mm burrs (both magnetic blind and holed types) fit natively with no extra parts.
Will my grind setting change after cleaning or a burr swap?
No. The patented internal leveling mechanism and independent spindle are designed so that disassembly for cleaning or burr replacement does not affect grind calibration. Your dial position stays accurate after reassembly.
Is the YEH-98L compatible with 110V / 120V power?
The YEH-98L is rated for 220V / 50–60Hz. North American customers will need a step-up voltage transformer. Please verify your local power requirements before ordering.
Precautions for Scale Adjustment
This machine is manufactured with the 0 mark set as the tool setting position. Do not tighten the scale beyond 0 before turning on the machine, as this may cause wear on the tool disc and affect accuracy. When adjusting the scale, it is recommended to first set the speed to the lowest setting while the machine is powered on, and then make fine adjustments to the scale. Scale adjustments should follow the principle of "from large to small". For example, if the target scale is 3, you can first back down to 4, and then slowly back down to 3 to obtain a more stable and accurate positioning.
Safety Warning
The equipment has undergone precision testing and blade leveling before leaving the factory. Do not loosen the leveling screws yourself. If disassembly or adjustment is required, please contact after-sales personnel first. Before disassembling any equipment part, the power must be turned off. It is strictly forbidden to disassemble any equipment part while the machine is powered on, especially critical components such as the bean inlet and powder outlet. Do not grind anything other than coffee beans. Do not insert fingers or foreign objects into the grinding or powder outlet areas while the equipment is running. If abnormal noise, odor, or overheating occurs, immediately stop the machine, disconnect the power, and contact after-sales service.
