When the sewing machine has not been used for a
relatively long period of time or something has been done
to the components related to oil circulation at the time
of maintenance and inspection, there is a case where
the circulation function of oil has been lost. This occurs
because air enters in the circulation route.
In this case, it can be checked with oil circulation check
windows 1 and 2 .
When the circulation of oil cannot be checked, remove two
pump screws of 3 , apply a few drops of oil until the oil
surface can be checked there.
