3.9 Lubrication
3.9.1 General information
The oil passes from the oil supply container 3 to the oil sump 2. This
oil is used for lubricating the lubrication points in the arm and head
area.
The oil projected by the crank drive passes via the wick 1 to the hook
oil container 5. This oil is used for lubricating the hook. The oil
exceeding the MAX mark is returned by the pump 4 to the upper oil
container 3.
The oil of the container 3 flows via a wick connection to the hook oil
container 5.
This ensures an effective lubrication and low oil consumption.
Caution: Danger of bodily injuries !
Turn off main switch.
Switch off the sewing machine before carrying out any work on the oil
circulation system.
ATTENTION !
When proceeding to the installation work ensure that the hose ends
are again properly connected to the pump.
