PREVENTIVE MAINTENANCE
Daily Maintenance (During Each Preventive
Maintenance Break)
1. Verify that high voltage is OFF and that
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
necessary.
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
excessive, replace covers as required. If
cloths are wet, find source and replace with
dry cloth covers.

† The high voltage must be turned OFF be-
fore entering the spray area and performing
any maintenance procedures. Spray booth
exhaust fan(s) should remain ON while
cleaning the equipment with solvents.
† Make sure high voltage is OFF before
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.
† Maximum flow rate should not exceed
800 cc/min.
† Daily removal and soaking of the bell
cup may not be required if the bell cup is
properly flushed. However, the frequency
of the feed tube and internal motor shaft
inspection indicated below under weekly
maintenance can be done daily and later
adjusted to weekly or as required depend-
ing on the results of the inspection.
† In the event the bell cup comes in con-
tact with a part, that cup should be replaced
before continuing to spray.
† Do Not place high voltage test probe on
bell edge unless rotation is fully stopped.
† Make sure that no solvent or other
contamination is allowed to enter the motor
assembly (air bearing and outer shaft).
