† Make sure that no solvent or other con-
tamination is allowed to enter the motor as-
sembly (air bearing and outer shaft).

† Do not use reclaim solvent containing
d-Limonene to soak bell cups.
!
† It may be necessary to remove the bell
cups for cleaning more frequently than
weekly. (See "Caution" under "Daily Main-
tenance".)
NOTE
• Check the high voltage connection by removing
the cable assembly from the resistor block.
Examine the tip of the banana plug for any
contaminants or corrosion. Clean or replace the
plug as required. Prior to reinstalling the cable
assembly, start at the rear of the banana plug
and cover about 6 inches of high voltage cable
with a thin film of dielectric grease. Insert the high
voltage cable until the banana plug seats into the
connector within the resistor block. The blind
depth inside the resistor block is approximately
7-5/8 inch. Ensure that the high voltage cable
is properly seated, tighten the strain relief, and
reinstall the connector cover. In an oscillation
or reciprocator type application, always ensure
adequate cable slack between the applicator
and the power supply termination point.
• Remove the front shroud and check for any signs
of solvent or paint leakage. Clean as required.
• Check position of high voltage tube where it
enters the motor housing. Make sure the o-ring
is not exposed. If so, push the tube in place.
• Remove bell cup and soak in solvent (MEK and
Xylene blend) for 1 to 2 hours. Remove from
cleaning solution and blow dry before replacing.
Make sure the o-ring is not exposed. If so, push
the tube in place.
• Remove bell cup and soak in solvent (MEK and
Xylene blend) for 1 to 2 hours. Remove from
cleaning solution and blow dry before replacing.
† The outer protective wrap may have to
be replaced more frequently than week-
ly. Daily inspection of the amount of paint
buildup on the wrap will determine the fre-
quency of replacement.
NOTE
• 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 as-
sembly following the disassembly procedures
and clean out the inside diameter of the motor
shaft using a tube brush and solvent. Clean the
outer surfaces of the feed tube.
• Release the rear cover fasteners and slide the
shroud back to expose the fluid manifold and
regulator. 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 rear shroud, bell cup, and front shroud.
Rewrap the outer housing and insulator mount-
ing rod (refer to “Disassembly Procedures” for
definite instructions).
