for a period long enough to bleed the
air.
• When using a Type 111, 112 or 114 nozzle,
dispense adhesive 10 centimeters or
more from the nozzle tip.
• When using a nozzle with a large diameter
hole other than the above nozzles,
dispense adhesive approximately 5
centimeters from the nozzle tip.

If adhesive dispensing from nozzle is poor,
then check for:
• Clogged or soiled nozzle
• Low dispensing pressure
• Incorrectly clamped syringe adapter
• Incorrectly set nozzle
• Wrong heater temperature
• Old adhesive
• Adhesive that was used several times

1.2 Cleaning the nozzles
The nozzle cannot function correctly if it is poorly cleaned and used while solder or adhesive is still sticking to
the nozzle tip. To prevent poor nozzle dispensing, inspect and clean each nozzle daily.
e
1
Remove the nozzle.
Always set the machine to emergency stop and open the cover before removing the nozzle.
2
Remove the dispense nozzle from
the joint nozzle.
1. Use an air blow tool to remove adhesive
and other matter from inside the nozzle.
2. Using a hex wrench, remove the dispense
nozzle from the joint nozzle.
3. Using a lint-free cleaning paper twisted
and formed in the shape of a toothpick,
wipe off adhesive and other matter
remaining inside the nozzle and joint
nozzle.

Remove adhesive with an air blow
tool.
1. After washing the joint nozzle with solvent
such as acetone, clean the joint nozzle
with an air blow tool.
2. Also clean the dispense nozzle using the
same procedure.
3. Using a lint-free cleaning paper twisted
and formed in the shape of a toothpick,
wipe the inside of the dispense nozzle
and joint nozzle.

Clean the nozzle hole.
1. Clean the nozzle hole using the cleaning
pin matching the size of the nozzle hole.
c
CAUTION
Clean carefully so as not to scratch the path.
2. Clean the nozzle hole once again with
an air blow tool.
3. Make a visual check for any adhesive
residue remaining inside the joint nozzle
and dispense nozzle holes.

If using an ultrasonic cleaner
• This can efficiently clean away adhesive or other
material adhering to the entire nozzle. However,
always make a visual check for any grime or other
material after cleaning.
• If a nozzle is placed in the ultrasonic cleaner solvent
without wiping away adhesive inside the nozzle, the
adhesive will react with the solvent and adhere to
the walls of the nozzle, causing nozzle clogs or
blockages.
• After cleaning the removed nozzle hole, immerse
the nozzle into a container filled with alcohol or
stored is inside a clean case, etc.
