Weekly Maintenance (Prior to Start or End of
Production Week)
•
Monitor rotational speed of all belts at the
speed control. Investigate cause if abnor-
mal.
•
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
beakered readings.
•
Check solvent flow by opening solvent valve
and taking a beakered reading (should be
within approx. 10% of target flow rate).
•
Paint residue found in the shaping air holes
is not acceptable and must be removed pri-
or to applicator use (see “Cleaning Shaping
Air Holes” in the “Maintenance” section).
•
Remove protective cover from out housing
and discard. Clean any paint on outer sur-
face of front and rear housing with soft cloth
In the event the bell cup comes in
contact with a part, that cup should be
replaced before continuing to spray.
Do Not place high voltage test probe
on bell edge unless rotation is fully
stopped.
Normally the cloth covers will not need
replacement daily and could last about one
week depending on application. (See “Weekly
Maintenance” in the “Maintenance” section.
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.
dampened with solvent. (See “Warning” on
avoiding the use of cleaning solvent con-
taining 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.
•
Visually inspect for signs of fluid leaks
around fluid connections and manifold.
Correct problem and clean paint from all
components, including internal portion of
shroud.
•
It may be necessary to remove the bell cups
for cleaning more frequently then weekly.
(See Note under “Daily Maintenance” in the
“Maintenance” section.)
•
With bearing air off, carefully inspect the
feed tube tip and clean any paint build-up
that has occurred on the feed tube tip. Us-
ing 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 following the disassembly proce-
dures and clean out the inside diameter of
the motor shaft using a tube brush and sol-
vent. Clean the outer surfaces of the feed
tube.
•
Reinstall bell cup and front shroud, replace
cover on the outer housing. (Refer to “Dis-
assembly Procedures” in the “Maintenance”
section for definite instructions.)
C A U T I O N
!
Maximum flow rate should not exceed
800 cc/min.
Make sure that no solvent or other con-
tamination is allowed to enter the motor as-
sembly (air bearing and outer shaft).
