I) The amount
of
oi
l shown in the samples on the left
should be finely adjusted in accordance with sewing
processes. Be careful not to excessively increase/
decrease the amount
of
oil
in
the hook. (If the amount
of
oil is too smal, the hook will be seized (the hook
will be hot).
If
the amount
of
oil
is
too much, the
sewing product maybe stained with oil.)
2) Adjust the amount
of
oil
in
the hook so that the oil
amount ( oil splashes ) should not change while
checking the oil amount three times (on the three
sheets
of
paper)
