RMA-303 Direct Charge - Maintenance

DISASSEMBLY PROCEDURES
For reassembly instructions, use the reverse of
the following disassembly procedures.
To facilitate atomizer removal from hose mani-
fold, a robot program should be made that
purges all paints and solvents from the RMA-
303. Ideally it would then position the bell as-
sembly in a bell removal position where the
bell cup is pointed downward at a 30° angle.
Any residual solvents would be contained in
the “J bend “ of the robot wrist.
All O-rings described in the “Maintenance” sec-
tion of this manual should be lubricated with a
food grade petroleum jelly or with A11545 lub-
ricant.
Atomizer Removal / Replacement
Using the applicator removal tool (76772-00)
insert the pin diameter of the wrench into one
of the four (4) holes of OD of the quick discon-
nect ring. Apply a force to the tool in a counter
-clockwise direction as shown in “Applicator
Removal from Robot” figure.

Carefully remove the quick disconnect
ring to ensure any residual line pressure
has been relieved to atmosphere.
Bell Cup Removal / Replacement
The bell cup should always be the first compo-
nent removed if any maintenance is per-
formed. Following the procedure will minimize
the risk of damage to the cup.
Lay the applicator on its side of a clean and
secure area, preferably an area where irregu-
lar maintenance is performed. Using the large
open end of the bell cup / combo wrench
(A12061-00) on the flats of the turbine shaft,
carefully hold the outside of the bell cup with
one hand while applying a clockwise force to
the wrench. The bell cup is a right hand
thread and must be turned counter-clockwise
to remove.
Place the bell cup in a safe and secure place.
Carefully inspect the cup for any damage. If
there is any damage to the cup, it must be re-
placed.
