Cleaning; Daily Cleaning; Changing The Lubricating Oil (Every Three Months) - Brother DA-9270 Instruction Manual

8. CLEANING

The following cleaning operations should be carried out each day in order to maintain the performance of this machine
and to ensure a long service life.
¡
Turn off the power switch before carrying out cleaning. The motor will keep turning even after the power
is switched off as a result of the motor's inertia. Wait until the motor stops fully before starting work.
The machine may operate if the treadle is pressed by mistake, which could result in injury.
¡
Be sure to wear protective goggles and gloves when handling the lubricating oil, so that no oil gets into
your eyes or onto your skin, otherwise inflammation can result.
Furthermore, do not drink the oil under any circumstances, as it can cause vomiting and diarrhoea.
Keep the oil out of the reach of children.
