Maintenance And Inspection; Checking The Needle; Cleaning The Rotary Hook - Brother KE-430B Instruction Manual

9. MAINTENANCE AND INSPECTION

Turn off the power switch before carrying out cleaning, otherwise the machine may operate if the
foot 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.
Wait until the motor has cooled down before cleaning the air holes.
The motor may be hot immediately after it has been used, and it may cause burns if touched.
