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.

• For the first time you fill the oil tank with oil, add 280 cc of oil as a guide and check to be sure
that the oil amount indicating rod works. If the oil amount indicating rod does not work, bring it
to the workable state by tiling the sewing machine once.
• When you use a new sewing machine or a sewing machine after an extended period of disuse,
use the sewing machine after performing break-in at 2,000 sti/min or less.
• For the oil for hook lubrication, purchase JUKI NEW DEFRIX OIL No. 1 (Part No. : MD-
FRX1600C0) or JUKI MACHINE OIL #7 (Part No. : MML007600CA).
• Be sure to lubricate clean oil.
In case of the circulation type lubrication method, when using the sewing machine for the first
time, the oil amount in the oil tank decreases until the oil has collected in the filer for circulation.
When the top end of oil amount indicating rod is lower than the lower engraved marker line, add
the oil to the oil tank again so that the top end enters between the upper and lower engraved
marker lines.
