WARNING :
1. Turn off the power switch before carrying out cleaning. The machine may operate if the treadle is
pressed incautiously, which could result in injury.
2. Be sure to wear protective goggles and gloves when handling the lubricating oil and grease so that
they do not get into your eyes or onto your skin, otherwise inflammation can be resulted.
3. Furthermore, do not drink or eat the oil nor the grease for they can cause vomiting and diarrhea.
Keep the oil away of the reach of children.
4. Use both hands to hold the machine head when tilting or returning it to its original position.
If only using one hand to move the machine, the weight of the machine head may cause slipping
