† The protective disposable wrap is for
one time use only. Do not wash and reuse
the wrap.
NOTE
† Normally the wrap will not need re-
placement daily and could last about one
week. See "Weekly Maintenance" in the
"Maintenance" section.
NOTE
† Maximum flow rate should not exceed
500 cc/minute.

• Wait for rotation to cease and then clean off bell
cup edge and shaping air ring and any other
outer surfaces. Use a soft cloth dampened with
solvent.
• Visually inspect the bell cup edge for signs of
abrasion. If the coating is excessively worn
back (1/16 inch or more) or badly chipped as
the result of contact with a part, replace the cup.
• Check bell cup voltage using high voltage
probe. Voltage should be approximately 85
kV when 100 kV is set on the power supply.
• Check the amount of paint build up on the outer
protective wrap. If excessive, replace wrap as
required.

† Do not place high voltage probe on bell
edge unless rotation is fully stopped.

† In the event the bell cup comes in con-
tact with a part, that cup should be checked
for damage and replaced if necessary be-
fore continuing to spray.

Weekly Maintenance
(Prior to Start or End of Production Week)
† Refer to the "Troubleshooting Guide"
(Figure 15) for details on determining the
causes of low or no high voltage at the bell cup.
NOTE
• Monitor rotational speed of all bells at the speed
control (should be within approximately 5% of
target speed).
• Monitor high voltage output indicated on the
display of the control unit or at the meter of the
power supply (should be within approximately
5% of target output).
• Check paint flow on all bells at minimum and
maximum specified settings by taking beakered
readings.
• Check solvent flow by opening solvent valve
and taking a beakered reading (should be within
approximately 10% of target flow rate).
• Remove protective wrap from outer housing
and discard. Clean any paint on outer surface
of front and rear housing with soft cloth damp-
ened with solvent. (See “Warning” under “Daily
Maintenance” on avoiding the use of cleaning
solvent containing d-Limonene.)
