† Maximum flow rate should not
exceed 700 cc/min.
† Daily removal and soaking of the bell
cup may not be required if the bell cup is
properly flushed. However, the frequen-cy
of the feed tube and internal motor shaft
inspection indicated under "Weekly Main-
tenance" can be done daily and later ad-
justed to weekly or as required depending
on the results of the inspection.

† Make sure high voltage is OFF be-fore
approaching applicator with solvent cloth.
† Do not use reclaim solvent containing
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 performing any maintenance pro-
cedures. Spray booth exhaust fan(s)
should remain 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 assem-
bly 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 turbine 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 (5.64-7.91 Nm) torque.
9. Check the amount of paint build-up on the
outer protective cloth covers, if used. If exces-
sive, replace cover as required.
