Lubrication - JUKI DDL-900B Instruction Manual

10. Lubrication

WARNING :
1. Do not connect the power plug until the lubrication has been completed so as to prevent acci-
dents 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 CORPORATION GENUINE OIL 7 (Part No. :
MML007600CA).
3. Be sure to lubricate clean oil.
4. Be aware oil leakage can occur if the surface of added oil quantity exceeds MAX. line A.
5. Transporting the sewing machine with the sewing machine filled with oil can give rise to the
risk of oil leakage. Be sure to discharge oil from the sewing machine through drain cock ❺.

1) Before running the sewing machine, remove
rubber plug ❶ from the top of the machine arm,
and add oil through the oil inlet using accessory
funnel ❹ supplied with the sewing machine.
2) Fill the oil tank with the oil until the top end of
oil amount indicating rod ❸ comes between the
upper engraved marker line A and the lower
engraved marker line B of oil amount indicating
window ❷.
If the oil is filled excessively, it will lead from the
junction between the oil shield and bed, or from
the junction between the rubber plug and bed,
or proper lubrication will not be performed. So,
be careful. In addition, when the oil is vigorously
filled, it may overflow from the oil hole. So, be
careful.
* When oil is added until MAX. line A is reached,
the oil quantity becomes 600 cc.
* Check the oil quantity while the sewing ma-
chine is at rest.
* Check the quantity of oil in the oil tank by view-
ing the oil surface from the side of oil amount
indicating window ❷.
3) When you operate the sewing machine, refill oil if
the top end of oil amount indicating rod ❸ comes
down to the lower engraved marker line B of oil
amount indicating window ❷.
4) When you operate the machine after lubrication,
you will see splashing oil through oil sight window
❻ if the lubrication is adequate.
* Note that the amount of the splashing oil is
unrelated to the amount of the lubricating oil.
