7. MAINTENANCE AND INSPECTION
Turn off the power switch before starting any cleaning work, otherwise the machine may operate
if the start switch 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.

7-1.Cleaning the rotary hook

NOTE: If there are scraps of thread sticking to the rotary hook, it will cause a synchronization error (code
E-320) to be displayed. Clean the rotary hook at least once per day to avoid this.
1. Open the lower shaft module
and remove the bobbin case.

7-2.Lubrication

NOTE Fill the machine with oil when the oil level is down to about one-third full in the oil sight glass.
If oil is not added and the oil drops below this level, there is the danger that the machine may seize
during operation.
Be sure to let the machine operate for a while after adding the oil.
Use only specified Brother oil (Nisseki Sewing Lube 10) for the machine oil.
