7. ADJUSTING THE AMOUNT OF OIL ( OIL SPLASHES ) IN THE HOOK

When carrying out the procedure described below in 2, remove the slide plate and take extreme

caution not to allow your fingers to come in contact with the hook.

1) If the machine has not been sufficiently warmed up for operation, make the machine run idle for

approximately three minutes. (Moderate intermittent operation)

2) Place the amount of oil (oil spots) confirmation paper under the hook while the sewing machine

is in operation.

3) Confirm the height of the oil surface in the oil reservoir is within the range between

"HIGH" and "LOW.

4) Confirmation of the amount of oil should be completed in five seconds.

(Check the period of time with a watch)

1) The amount of oil 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 small,

the hook will be seized (the hook will be hot).

If the amount of oil is too much, the sewing

product may be 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).

WARNING:

Be extremely careful about the operation of the machine since the amount of oil has to be

checked by turning the hook at a high speed.
