† Refer to the "Troubleshooting Guide"
in the "Maintenance" section for details on
determining the causes of low or no high
voltage at the bell cup.
NOTE
Weekly Maintenance
(Prior to Start or End of Production Week)
• Monitor rotational speed of all bells at the
speed control. Investigate cause if abnormal.
• Monitor high voltage and current output indi-
cated on the MicroPak display. Investigate
cause if abnormal.
• Check paint flow on all bells at minimum and
maximum specified settings by taking beak-
ered readings.
• Check solvent flow by opening solvent valve
and taking a beakered reading (should be
within approx. 10% of target flow rate).
NOTE
† It may be necessary to remove the bell
cups for cleaning more frequently than
weekly. (See Note under "Daily Mainte-
nance" in the "Maintenance" section.)
† Do not place high voltage test probe
on bell edge unless rotation is fully
stopped.
† Maximum flow rate should not ex-
ceed 700 cc/min.

† In the event the bell cup comes in
contact with a part, that cup should be
replaced before continuing to spray.

NOTE
† Normally the cloth covers will not need
replacement daily and could last about
one week depending on application. (See
"Weekly Maintenance" in the "Mainte-
nance" section.
• Paint residue found in the shaping air holes is
not acceptable and must be removed prior to
assembly (see "Cleaning Shaping Air Holes"
in the "Maintenance" section).
• Remove protective cover from outer housing
and discard. Clean any paint on outer sur-
face of front and rear housing with soft cloth
dampened with solvent. (See "Warning", on
previous page, on avoiding the use of clean-
ing solvent containing d-Limonene.)
• Remove the front shroud and check for any
signs of solvent or paint leakage. Clean as
required.
• Remove bell cup and soak in solvent for 1-2
hours. Clean with a soft brush as required.
Remove from cleaning solution and blow dry
before replacing.
• With bearing air off, carefully inspect the feed
tube tip and clean any paint build-up that has
occurred on the feed tube tip. Using a pen
light, determine if there is build-up of paint in
the motor shaft and/or around the paint feed
tube. If so, remove the motor assembly fol-
lowing the disassembly procedures and clean
out the inside diameter of the motor shaft us-
ing a tube brush and solvent. Clean the outer
surfaces of the feed tube.
