12) Cleaning
(1) The area around the feed dog and the hook should be cleaned every day.
(2) Remove any thread scraps from inside the rotary hook.
(3) Keep the control box clean.
13) Lubrication
(1) Check the oil level at the sight glass 1 every week. If the oil is
not enough, remove oil-filling screw 2 and pour in oil. Check
oil level at sight glass 2. The oil level must be between
“EMPTY” and “FULL”. Replace oil-filling screw 2. After
running for 500 hours since buying the new sewing machine,
the oil must be changed. Then change the oil every two years.
(2) The oil quantity is pre-set at a relatively high level in order to
ensure adequate lubrication during running–in. This setting should be checked and corrected after
running-in. (approx. 50 hours).
The hook is to have positive
lubrication with the least
possible amount of oil. Let the
sewing machine run approx.2
minutes. And run in intervals.
Hold a piece of paper next to
the hook and check if sufficient oil is spun oil onto the paper. Remove cover plate 2. Loosen screw 3 until
the tube 1 no longer moves. This is the case when the tube is in the center of the drilled hole. Turn screw 3
