MAINTENANCE
1. Lubrication
Apply oil to the section (near the upper looper shaft) described in the Instruction Manual.
Before lubrication, remove dust or cloth chips from the section to be applied with oil.
2. Grease application
After the disassembly of the section to/in which grease is applied or lled, re-apply or re-ll grease. The rec-
ommended grease is as described below:
JUKI Grease A
・

・
Tube (100 g) JUKI part No.: 23640204
If you do not have a grease pump, it is recommended to ll a plastic oiler with grease or to use a syringe with-
out a needle.
・
Syringe specically for grease application JUKI part No.: GDS01007000
3. Looper threader
Do not lubricate inside the pipe. If the inside of the pipe is contaminated with oil, thread cannot be passed
through it.
In addition, thread cannot be passed through the pipe either after having passed a thread absorbed with sili-
con oil through it.
Should the pipe is lubricated
Remove oil from inside the pipe by passing a thick thread (cotton thread count of which is #20 or
smaller) through the pipe. Or, blow away the oil from inside the pipe with high-pressure air.
If the thread still cannot be passed smoothly through the pipe, other causes such that the mixture of lint
and oil adheres near the pipe joints or thread inlet section should be considered. In such a case, detach
the pipe and clean it up with degreaser or the like.
