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
(JUKI GREASE A) is effective (approximately once every
one to two years).
(Cautions)
1. Do not apply oil to the sections which are lubricated with
grease.
2. Be aware that grease can leak from the thread take-up cover
and needle bar if the amount of grease is excessive.
3. Be sure to use JUKI GREASE A
❶
.
1) Grease-up warning and grease-up error
When the machine needs replenishment of grease, error E220
warning against shortage of grease and E221 grease-up error
are displayed.
Once the alarm is displayed, replenish grease according to the
instructions 2) to 4).
To cancel the error, refer to "4.-(3)-[3]-1 How to cancel grease-up
error".
2) 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

and needle bar
lower bushing greasing screw
❸
(only for the DDL-8000A*-MS)
with a hexagonal wrench.
3. Remove the cap of JUKI GREASE A TUBE
❶
. Insert its tip into
the oil hole and replenish grease from exclusive JUKI GREASE
A
❶
.
At this time, add grease until it overflows the oil hole.
4. Push overflowing JUKI GREASE A
❶
with the oil filling screw into
the oil hole.
5. Wipe the excess of JUKI GREASE A
❶
off the area around the
oil hole.
(Caution) When a lubricant is newly replenished, operate the
sewing machine for about 10 seconds of idling. A
surplus amount of JUKI GREASE A
❶
may be dis-
charged at that time. Wipe it off then. Repeat this
operation several times and use the sewing machine
regularly after the generation of the excessive JUKI
GREASE A
❶
has disappeared.
