one of the conditions may result in bearing
damage and turbine failure. Warranty DOES
NOT
cover failure caused by imbalanced load-
ing conditions.
To determine if the bell is dirty or damaged,
remove the bell cup and turn the turbine ON.
If the noise is eliminated, the bell cup is the
problem. If the noise continues, the turbine
may be damaged and should be inspected.
Excessive air required to achieve same speed
may indicate a faulty or contaminated turbine.
DO NOT
continue to operate a noisy turbine.

•
If a bell cup comes off a rotating shaft be-
cause of motor seizing or any other reason,
the atomizer and bell cup must be returned
to Ransburg for inspection and evaluation
to determine if the bell can be used in oper-
ation.
TURBINE MAINTENANCE
DO NOT attempt to rebuild the turbine. Any
endeavor to disassemble a turbine during the
warranty period will void the warranty. The
turbine is non-field serviceable. Contact your
authorized distributor or Ransburg for instruc-
tions.

GENERAL MAINTENANCE
Verify daily that the operating parameters have
not varied significantly from the normal. A dras-
tic change in high voltage, operating current, tur-
bine 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 atomiz-
er 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 applica-
tor using a lint-free rag dampened with sol-
vent.
6. After cleaning, all conductive residue must
be removed using a non-conductive sol-
vent. Since electrostatic equipment is in-
volved, these solvents should also be non-
polar (Naphtha).
