APPLICATOR ASSEMBLY
CLEANING PROCEDURE
Routine Cleaning
Equipment Needed
• An appropriate solvent
• A solvent safety container (grounded)
• A small soft-bristled brush
• The Ransburg special multi-purpose
wrench (19749-00)
2. Trigger the applicator (high voltage ON).
3. Slowly approach the applicator electrode to
any grounded object and make contact.
4. Monitor the current output reading on the
voltage supply meter as the applicator ap-
proaches ground:
Upon ground contact, the power supply should
display at least 140 µA and the green, yellow,
and red LED's of the microamp bar graph meter
should all be illuminated.
If the reading is outside of the acceptable range
(135-140 microamperes), DO NOT use the appli-
cator until the problem has been corrected (see
"Troubleshooting Guide" in the "Maintenance"
section).
5. Release the trigger (high voltage OFF) and
turn the power supply power OFF.
Shutdown (or at end of each shift)
1. Turn the power supply power OFF.
2. Turn the paint supply OFF.
3. Turn the atomizing and fan air OFF.
4. Wipe the applicator, cable, and hoses with a
rag and a suitable cleaning solvent.
5. Flush the lines and allow the solvent to re-
main in the lines unpressured (see "Flushing
Procedures" in the "Maintenance" section).
† If the coating material is fast settling
and the fluid lines are not flushed soon
enough, the internal passages may be-
come clogged. This can lead to excessive
downtime for repair.

† If production downtime is to be short,
the fluid lines may not require flushing,
depending on the coating material being
used. If the solids in the material settle
slowly, the lines will not need to be flushed
as soon after shutdown as with fast set-
tling solids. The paint being used and the
length of downtime will determine the need
for flushing. Metallic paint and primer will
require flushing sooner than other types of
coating materials.
NOTE
Weekly
• Check the entire system for damage, leaks,
and paint accumulation.
• Clean the atomizer assembly.
