14.3.3 Laser align sensor (MNLA/FMLA head)

Check to see if there is any dirt on the sensor window.

If the sensor window is dirty or unclear, clean it with clean cloth or gauze lightly

moistened with alcohol.

Note: If you use not alcohol but any solution such as acetone and thinner, the resin

part around the sensor window may fuse. Never use any solvent other than

alcohol.

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 Nozzle

Clean a nozzle with putting it into a supersonic cleaning bath containing alcohol.

After cleaning, blow off alcohol inside the nozzle with an air gun or similar device,

install the nozzle on the ATC unit again, and perform the "ATC nozzle setup" menu

item on the Machine Setup menu.

Clean a nozzle with a supersonic cleaning bath for five minutes. Dampen soft cloth

with alcohol and use it to clean the urethane part and any part of the nozzle diffuser

on which stains remain stuck to even after you use a supersonic cleaning bath to

clean it.

After cleaning a nozzle, apply New Deflex Oil No. 1 to a nozzle slider to protect the

inside of the nozzle from rust.

Notes: 1. Do not install the nozzle to the head, but install it in the ATC unit.

2. Since the urethane part of nozzles 505, 506, 507 and 508 may be

degraded or flake off when they are damped into alcohol for a long time,

turn the nozzle upside down and insert it to the bath as shown in the

figure below so that any urethane part cannot be dampened into alcohol.

3. Never use any solvent (such as acetone) other than alcohol.

4. Never disassemble a nozzle.

5. After cleaning the nozzle, do no apply any grease other than New Deflex

oil No.1 to it.

6. Be careful not to apply any New Deflex Oil No. 1 to the nozzle diffuser

and rubber section.

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.
