OFF be-fore
approaching applicator with solvent cloth.

DO NOT use reclaim solvent contain-
ing d-Limonene. This can cause damage
to certain plastic components.

DO NOT stop bell rotation by using a
rag or gloved hand against the bell cup
edge.

The high voltage must be turned OFF
before entering the spray area and per-
forming any maintenance procedures.
Spray booth exhaust fan(s) should re-
main ON while cleaning the equipment
with solvents.

GENERAL MAINTENANCE
Verify daily that the operating parameters have
not varied significantly from the normal. A drastic
change in high voltage, operating current, turbine
air, or shaping air, can be an early indicator of
potential component failure.
A laminated poster entitled “Rotary Atomizer
Checklist” (AER0075) is included with the as-
sembly in the Literature Kit to be posted near the
station as a handy reference.
Due to the close proximity of high voltage to
ground potential, a schedule must be developed
for equipment maintenance (cleanliness).
PREVENTIVE MAINTENANCE
Daily Maintenance
(During Each Preventive Maintenance Break)
1. Verify that high voltage is OFF and that both
inner and outer shaping air, bearing air, and tur-
bine drive air are ON.
2. Open the dump valve, flushing all paint from
the supply lines and valve module.
3. Open the solvent valve, flushing all paint
from the fluid tube and through the atomizer bell
assembly.
4. Re-verify that high voltage is OFF, turbine
drive air is OFF, and that the bell cup has
stopped spinning. The bearing air and shaping
air should remain ON.
5. Clean all external surfaces of the applicator
using a lint-free rag dampened with solvent.
6. After cleaning, all conductive residue must
be removed using a non-conductive solvent.
Since electrostatic equipment is involved, these
solvents should also be non-polar (Naphtha).
7. Inspect bell cup for nicks, dents, heavy
scratches, or excessive wear. Replace if nec-
essary.
8. Check bell cup tightness. Tighten to 50-70
lbs•in (5.65-7.91 Nm) torque.
9. Check the amount of paint build-up on the
outer protective cloth covers, if used. If exces-
sive, replace covers as required. If cloths are wet,
find source and replace with dry cloth covers.
