RMA-303 Indirect Charge - Maintenance

> The outer protective cover may have to be
replaced more frequently than weekly. Daily
inspection of the amount of paint buildup on
the cover will determine the frequency of re-
placement.
DISASSEMBLY PROCEDURES
> For re-assembly instructions, use the re-
verse of the following disassembly proce-
dures.
> To facilitate atomizer removal from hose
manifold, a robot program should be made
that purges all paints and solvents from the
RMA-303. Ideally it would then position the
bell assembly in a bell removal position where
the bell cup is pointed downward at a 30° an-
gle. Any residual solvents would be con-
tained in the "J bend" of the robot wrist.
> All O-rings described in the "Maintenance"
section of this manual should be lubricated
with a food grade petroleum jelly or with
A11545 lubricant.
Atomizer Removal/Replacement
> Prior to removing applicator from the robot,
the following tasks must be completed:
•
Robot put into E-stop mode, locked, and
tagged-out.
•
All fluid passages are cleaned, purged
out, and depressurized.
•
Air turned off.
Atomizer Removal
(See Figure13)
Remove rear split shroud by loosening the
flat head retaining screws and pulling the
shroud halves away from the atomizer exten-
sion. Loosen the high voltage nut (78441-00)
that holds the high voltage cable into the
curved high voltage tube. Remove the high
voltage nut and ferrules from the high voltage
cable. Loosen the quick disconnect ring
(A11201-00) with the adjustable spanner
wrench (76772-00) in a counter-clockwise
direction. Pull atomizer away from robot
plate while taking care to feed the high volt-
age cable back through the atomizer.
