> Normally the cloth covers will not need re-
placement daily and could last about one week
depending on application. (See "Weekly
Maintenance" in the "Maintenance" section.)
Weekly Maintenance
(Prior to Start or End of Production Week)
•
Monitor rotational speed of all bells at the
speed control.
•
Monitor high voltage and current output
indicated on the MicroPak display.
•
Check paint flow on all bells at minimum
and maximum specified settings by taking
beaker readings.
•
Check solvent flow by opening solvent
valve and taking a beaker reading (should
be within approx. 10% of target flow rate).
> Maximum flow rate should not exceed 700
cc/min.
•
Paint residue found in the shaping air
holes is not acceptable and must be re-
moved prior to applicator use (see
"Cleaning Shaping Air Holes" in the
"Maintenance" section).
•
Remove protective cover from outer hous-
ing and discard. Clean any paint on outer
surface of front and rear housing with soft
cloth dampened with solvent. (See
"Warning" on previous page, on avoiding
the use of cleaning solvent containing d-
Limonene.)
•
Remove the front shroud and check for
any signs of solvent or paint leakage.
Clean as required or repair as required.
•
Remove bell cup and soak in solvent for 1-
2 hours. Clean with a soft brush as re-
quired. 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. 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 mo-
tor assembly following the disassembly
procedures and clean out the inside diame-
ter of the motor shaft using a tube brush
and solvent. Clean the outer surfaces of
the feed tube.
> Make sure that no solvent or other contami-
nation is allowed to enter the motor assembly
(air bearing and outer shaft).
•
Recheck bell cup tightness. Torque to 50-
70 lbs.- in. (5.65-7.91 Nm).
•
Remove the rear shroud to expose the flu-
id valve manifold assembly. Visually in-
spect for signs of fluid leaks around fluid
connections and manifold. Correct prob-
lem and clean paint from all components,
including internal portion of shroud.
•
Reinstall rear shroud, bell cup, and front
shroud and replace cover on the outer
housing (Refer to "Disassembly Proce-
dures" in the "Maintenance" section for
definite instructions).
