Oiling
Turn off the main power switch and unplug the machine.
To keep the machine running smoothly and quietly the
moving parts (on the upper looper), pointed out in the
picture, must be lubricated often. We recommend lubricating
once a week for normal use or once every 10 hours of
continuous use.
Use sewing machine oil. Do not use any other oil, it could
damage the machine.
With the machine unthreaded, place a scrap of fabric under
the presser foot and run the machine for a few minutes.
Wipe the machine surface to remove all excess oil before
sewing.
Important when oiling!
Never inject oil into the looper threader holes, the
pipe openings or the looper tips (marked in red in
the picture)
.
