A laminated poster entitled “Rotary Atomizer
Checklist", part number AER0075, is included
with the assembly to be posted near the station
as a handy reference.

• Open solvent valves and flush out feed tubes
and bell cups for 3-5 seconds (trigger and dump
valve closed).

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.
This can damage the resistance coating
at the bell cup edge.

• Wait for rotation to cease and then clean off
bell cup edge and shaping air ring and any other
non-protected (unwrapped) outer surfaces. Use
a soft cloth dampened with solvent. The protec-
tive disposable wrapping should be a material
such as the type used on electrostatic guns.
One such suitable material is manufactured by
Safety Ware, located in Fort Wayne, IN, tele-
phone 219-456-3535, or fax 219-744-9231.

• Visually inspect the bell cup edge for signs of
damage.

In the event the bell cup comes in

contact with a part, that cup should be
checked for damage and replaced if
necessary before continuing to spray.

Daily removal and soaking of the bell

cup may not be required if the bell cup is
properly flushed as indicated above.
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.

GENERAL

Verify daily that the operating parameters have
not varied from the set up standard. A drastic
change in system current, high voltage, turbine
air, shaping air pressure, or fluid pilot air pres-
sure can be an early indicator of a component
or system problem.

Maximum flow rate should not ex-

ceed 500 cc/minute.

C A U T I O N

!!!!!

• Check bell cup voltage using high voltage
probe. Voltage should be approximately 85 kV
when 100 kV is set on the power supply.

Do not place high voltage probe on

bell edge unless rotation is fully stopped.
