8. CLEANING AND MAINTENANCE
Turn off the power switch before starting any cleaning work, otherwise the machine may operate if the start
switch is pressed 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.
8-1. Cleaning
If using an air gun, do not use it while the machine head is tilted back, otherwise oil and thread scraps may adhere to the
cutter sensor and timing belt, resulting in operating problems.
