Lubrication; Adjusting The Amount Of Oil (Oil Splashes) - JUKI DDL-7000A-7 Series Instruction Manual

8. Lubrication

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.

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.
