5. Operating Instructions
The Victoria Manual Low Hopper Grain Grinder is suitable for grinding various dry ingredients including coffee beans, corn, wheat, oats, barley, rye, nuts, and spices. It can produce grinds from coarse to fine.
- Adjust Grind Size: The fineness of the grind is adjusted by tightening or loosening the adjustment screw located at the front of the grinder. Turn clockwise for a finer grind and counter-clockwise for a coarser grind. Make small adjustments and test the grind until the desired consistency is achieved.
- Load Hopper: Place the desired dry ingredients into the low hopper. The low hopper design allows for processing larger quantities.
- Begin Grinding: Turn the crank handle clockwise at a steady pace. The ingredients will be fed into the grinding plates and exit through the spout. Place a container beneath the spout to collect the ground material.
- Multiple Passes: For very fine grinds, especially with harder ingredients like corn or wheat, it may be necessary to pass the material through the grinder multiple times, gradually reducing the grind setting with each pass.

6. Maintenance and Cleaning
Proper maintenance ensures the longevity and performance of your grinder.
- Hand-Wash Only: All parts should be hand-washed. Do not use a dishwasher.
- Disassembly for Cleaning: For thorough cleaning, disassemble the grinder by removing the crank handle and loosening the adjustment screw to separate the grinding plates and other internal components.
- Wash and Rinse: Wash all parts with warm, soapy water. Use a brush to remove any stubborn residues. Rinse thoroughly to remove all soap.
- Dry Immediately: It is crucial to dry all cast iron components immediately and completely after washing to prevent rust. Use a clean cloth or paper towel.
- Keep Dry: Store the grinder in a dry environment. If storing for an extended period, a light coating of food-grade mineral oil on the cast iron parts can help prevent rust.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven grind consistency | Grind adjustment not optimal; ingredients fed too quickly; cotter pin misalignment. | Adjust the grind setting in smaller increments. Feed ingredients at a steady, moderate pace. Check cotter pin position for proper grinding plate closure. |
| Grinder is difficult to turn | Too much material in hopper; grind setting too fine for ingredient; internal obstruction. | Reduce the amount of material. Adjust to a coarser grind setting. Disassemble and check for obstructions. |
| Metal particles in ground material (initial use) | Manufacturing residue; initial wear of grinding plates. | Thoroughly clean the grinder before first use. Grind a small amount of sacrificial material (e.g., inexpensive rice) and discard it until no particles are observed. |
| Rust appearing on cast iron parts | Improper drying after washing; exposure to moisture. | Ensure all cast iron parts are completely dry immediately after washing. Apply a thin layer of food-grade mineral oil for protection, especially during storage. |
