Adjustment Procedure
Results of Improper Adjustment
(3)Application of appropriate grease
In ordinary usage, it is unnecessary to replenish the appropriate
grease ❶ (JUKI Grease A). Under particularly rigorous operat-
ing conditions, however, periodic replenishment of the appropriate
grease ❶ is effective (approximately once every one to two years).
(Caution) 1. When the machine needs replenishment of grease,
an alarm sounds. Once the alarm sounds, replenish
grease. In the case the machine is used under harsh
environment, it is recommended to replenish grease
once a year for ensuring effective greasing.
2. Do not apply oil to the sections which are lubricated
with grease.
3. Be aware that grease can leak from the thread take-
up cover and needle bar if the amount of grease is
excessive.
4. Be sure to use JUKI GREASE A TUBE ❶ (part
number : 40006323).
5. When a grease-up error has been displayed, the
start-up of a sewing machine is prohibited. Turn
on the sewing machine while pressing the
after grease up and set a memory switch K118 to 1.
1) Needle bar lower bushing and presser bar bushing
(Caution) Carry out greasing with the needle bar installed.
1. Remove the face plate.
2. Remove presser bar bushing greasing screw ❷ and needle
bar lower bushing greasing screw ❸ (only for the DDL-9000C-
SMS) with a hexagonal wrench.
3. Remove the cap of exclusive grease tube ❶. Insert its tip into
the oil hole and replenish grease from exclusive grease tube
❶.
At this time, add grease until it overows the oil hole.
4. Push overowing exclusive grease with the oil lling screw into
the oil hole.
5. Wipe the excess of grease off the area around the oil hole.
(Cautions) When a lubricant is newly replenished, operate
the sewing machine for about 10 seconds of idling.
A surplus amount of appropriate grease ❶ may be
discharged at that time. Wipe it off then. Repeat this
operation several times and use the sewing machine
regularly after the generation of the excessive appro-
priate grease ❶ has disappeared.
2) Feed bar mechanism
1. Take out the horizontal feed bar shaft ❹ feed the appropriate
grease to the grease groove.
* The horizontal feed bar shaft ❹ is processed to have a sacrice
M4 screw.
Use an M4 screw and pull it out easily by means of small cutting
pliers.
2. At the time of reassembly after the disassembly of various parts,
apply the appropriate grease to the sliding surfaces of the feed
bar mechanism.
