Turn off the power switch before carrying out these operations.
The machine may operate if the treadle is depressed by mistake, which could result in injury.
Be sure to wear protective goggles and gloves when handling the grease so that it does not get into your eyes or

Furthermore, do not drink the oil or eat the grease under any circumstances. Diarrhea or vomiting may result.
Keep the oil out of the reach of children.
