1. Setup: Some models have suction cups or clamps on the base to secure it in place for stability.
2. Preparation: Wash and peel (if necessary) the food item you want to grate. Cut it into a size that fits comfortably into the drum.
3. Drum Assembly: Open or detach the drum chamber from the grater’s main body. Insert the food item into the drum. The drum usually has sharp grating blades or holes on its surface.
4. Assembly: Close the drum chamber and make sure it’s securely locked into place.
5. Grating: As you rotate the handle, the food item comes into contact with the sharp grating blades inside the drum, resulting in grated or shredded pieces falling out through the holes in the drum.
6. Collection: Position a plate, bowl, or container beneath the grater’s exit area to catch the grated food as it falls.
7. Cleaning:  Depending on the design, you might need to unscrew or unlock the chamber to access the drum.

Here are some additional tips for using a manual tabletop drum grater effectively:

• Safety:  Always use the grater on a secure surface to prevent any accidents.
• Maintenance: Regularly clean the grater to prevent food residue from affecting its performance. Check the manufacturer’s instructions for specific cleaning recommendations.
• Variability: Some models might come with different drum attachments that offer various grating sizes (fine, medium, coarse) or even slicing options. Experiment with different drums to achieve the desired texture for your dishes.

Always consult the user manual provided by the manufacturer for detailed instructions on using and maintaining your specific manual tabletop drum grater model.
