at a super-high speed (JUKI MACHINE OIL #18) supplied with the unit or equivalent through the oil inlet.
When the oil surface reaches the space between two marker lines on the oil gauge, tighten oil sight window ❶ .
2) (Only for the MO-6800S) Before using a new sewing machine for the first time after the purchase or the
sewing machine which has not been used for an extended period of time, the shaded sections of needle
bar ❷ and upper looper guide ❸ have to be lubricated.
Take care not to pour too much amount of lubricating oil at the time of lubrication. If the ma-
chine is lubricated with an excessive amount of oil, oil leakage can be caused.
