RMA-303 Dual Purge Direct Charge - Maintenance
LN-9267-11.3 62
Refer to the “Troubleshooting Guide” in the
“Maintenance” section for details on determin-
ing the causes of low or no high voltage at the
bell cup.
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
indicated on the MicroPak display. Investi-
gate 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 re-
moved prior to applicator use (see
“Cleaning Shaping Air Holes” in the
“Maintenance” section).
•
Clean any paint on outer surface of front
and rear housing with a soft cloth damp-
ened 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 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.
N O T E •
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 following the disas-
sembly procedures and clean out the in-
side diameter of the motor shaft using a
tube brush and solvent. Clean the outer
surfaces of the feed tube.
It may be necessary to remove the bell cups
for cleaning more frequently than weekly.
(See Note under “Daily Maintenance” in the
“Maintenance” section.)
•
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.
•
Reinstall bell cup and front shroud, re-
place cover on the outer housing. (Refer
to “Disassembly Procedures” in the
“Maintenance” section for definite instruc-
tions.)
•
Recheck bell cup tightness. Torque to 50-
70 lbs•in (5.65-7.91 Nm).
BELL CUP PREVENTIVE MAINTENANCE
It is the user’s responsibility to ensure proper
maintenance of the atomizer bell at all times.
Bell cup failure due to inadequate cleaning or
handling will not be covered under the War-
ranty. The “DO NOT” bullets (see “Operator/
Maintenance Warnings” in the “Maintenance”
section) listed are some examples of improper
handling which could adversely affect perfor-
mance or personnel safety and should not be
attempted for any reason.
