. CLEANING AND MAINTENANCE
Turn off the power switch before carrying out cleaning, otherwise 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 lubricating oil and grease, so that they do
not get into your eyes or onto your skin, otherwise inflammation can result.
Furthermore, do not drink the oil or eat the grease under any circumstances, as they can cause vomiting and
diarrhoea.
Keep the oil out of the reach of children.
