Cleaning Instructions
The outside of the machine can be cleaned with a damp cloth or common household polishing wax. Grinding parts should
be cleaned with a stiff brush or dry cloth. Do Not Use Water. See “Shear Disc Replacement” for instructions on assembling
and disassembling of grinder parts. Before reassembling, wipe motor shaft with 2 or 3 drops of common household lubricat-
ing oil in the area of feedworm engagement to make assembly easier.
For Models 250RH-2, 250RH-3:
Regular usage of the coffee hoppers will cause oils to accumulate on the inner surface, requiring occasional cleaning.
1. Remove hopper from grinder and empty all beans.
2. Use a soft, damp cloth with a small amount of liquid soap and clean hopper. Use a clean, damp cloth to remove the
soap residue. Do not immerse or fill hopper with water.
3. Allow hopper to completely air dry before refilling with beans.
4. Once the hopper is dry, refill with whole bean coffee, cover and replace on grinder.
