Ransburg MMA-570 Direct_Ind Charge Atomizer A13366 - Manual (Page 51)

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” (AER0075-02) is included with the
assembly 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
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.
W A R N I N G
!
† 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.
C A U T I O N !
† 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 indi-
cated below under weekly maintenance can
be done daily and later adjusted to weekly or
as required depending on the results of the
inspection.
