14.3.4.1 Applying Machine Oil to a Nozzle After Cleaning It
Moisture contained in ethanol or IPA (isopropyl alcohol) may rust the inner pats of a
nozzle if you leave the nozzle without drying it after cleaning it in a supersonic
cleaning bath. Therefore, be sure to apply New Deflex Oil No. 1 (JUKI part
number is MDFRX1001L0) to the nozzle slider.
Use a cotton swab lightly dampened with New Deflex Oil No. 1 to apply this oil to
the part of the nozzle shown below (the part popped up from the nozzle inner
section when you push the nozzle slider). After that, move the nozzle slider up and
down 20 to 30 times to apply oil to the nozzle slider thoroughly. Next, remove oil
stuck to the exterior of the nozzle inner section and excessive oil with a clean wiping
rag.
Note that nay oil should not be stuck to the nozzle diffuser and rubber section
(shaded section in the figure below).
Be sure to apply only New Deflex Oil No. 1 to the nozzle. If you apply any
high viscosity of oil such as grease to the nozzle, the nozzle slider cannot
move back to the original position easily.
WARNING
Solvent may be flamed. Be careful to handle it. Never use acetone.
Or the diffuser may be discolored. Be sure to wear a mask for organic
gas before cleaning a device. Some ingredient of IPA is hazardous to
humans.
WARNING
To prevent the body from injury which can be caused by accidental
activation of the machine, cut off the power to the machine before starting
to work.

14.3.4.2 Nozzle outer shaft
Stand the nozzle outer shaft as shown in the figure below so that the shaft label
cannot be dampened into any alcohol, and clean it with the ultrasound cleaner.
Clean the shaft with the ultrasound cleaner for ten minutes, which is a guideline.
After cleaning, use an air gun or similar device to blow alcohol from inside the
nozzle outer shaft.
To prevent the shaft from rusting, apply New Deflex Oil No. 1 between the nozzle
outer and the outer SP holder. Apply Albania grease to this area also so that the
shaft can slide more smoothly.
Notes: 1 Never use solution (such as acetone) other than alcohol.
2 Never disassemble the nozzle outer shaft.
3. After cleaning, never use any oil other than New Deflex oil No. 1 or
grease other than Albania grease to the nozzle outer shaft.

◇ About alcohol to be used
We recommend IPA or ethanol due to its cleaning efficiency, cost and availability.

14.3.4.3 Applying oil or grease to a nozzle after cleaning
After using ethanol or isopropyl alcohol (IPA) to clean a nozzle with an ultrasonic
cleaner, use a cotton swab to apply New Deflex Oil No. 1 (JUKI P/N:
MDFRX1001L0) between the nozzle outer and the outer SP holder. After greasing,
use an air gun or similar device to blow excessive oil and remove the remaining oil
with a wiping rag.
To make the nozzle outer slide smoothly, first apply Albania grease
(a-rice-grain-sized amount) to the tip of a toothpick, and apply this grease to the
area shown in Figure 2 (area between the nozzle outer and the outer SP holder).
Push up the nozzle outer, and apply grease (ball-sized amount of grease) to each of
three balls respectively. Move the nozzle outer up and down 20 to 30 times to
apply grease over the nozzle outer uniformly.
Be careful not to apply any oil or grease to the shaft label.

WARNING
Solution is flammable. Be careful to handle it.
Never use acetone. It may discolor the nozzle diffuser.
During greasing, be sure to wear a protective mask for organic gas. IPA
contains substances harmful to human bodies.
