WARNING :
1. Do not connect the power plug until the lubrication has been completed so as to prevent
accidents due to abrupt start of the sewing machine,
2. To prevent the occurrence of an inflammation or rash, immediately wash the related portions if
oil adheres to your eyes or other parts of your body.
3. If oil is mistakenly swallowed, diarrhea or vomitting may occur. Put oil in a place where children
cannot reach.
8. Lubrication
1) Before starting the sewing machine, fill oil pan

.
2) Add oil before the oil surface comes down to
reach the LOW mark
B
.
3) When you operate the machine after lubrication,
you will see splashing oil through oil sight window
❷
if the lubrication is adequate.
4) Note that the amount of the splashing oil is unre-
lated to the amount of the lubricating oil.
1. When you use a new sewing machine or a sewing machine after an extended period of dis-
use, use the sewing machine after performing break-in at 2,000 sti/min or less.
2. For the oil lubrication, purchase JUKI NEW DEFRIX OIL No. 1 (Part No. : MDFRX1600C0) or
JUKI MACHINE OIL #7 (Part No. : MML007600CA).
3. Be sure to lubricate clean oil.
4. When the oil surface is lower than the LOW mark, the oiling may be inconsistent. To prevent
inconsistent oiling, add oil before the oil surface comes down to reach the LOW mark.
