Run cold water while operating to solidify fats and grease, making them easier to grind and reducing run time.
- 💡
Feed waste slowly instead of dumping large quantities at once — this reduces motor strain and run time.
- ⚡
Grind ice cubes monthly to clean the blades and maintain grinding efficiency.
