foot switch is depressed by mistake, which
could result in injury.
Disassembly should only be carried out by a
qualified technician.
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 may result.
Furthermore, do not drink the oil or eat the
grease under any circumstances, as they may
cause vomiting and diarrhea.
Keep the oil out of the reach of children
