DISASSEMBLY PROCEDURES
NOTE
NOTE
† The outer protective cover may have
to be replaced more frequently than week-
ly. Daily inspection of the amount of paint
build-up on the cover will determine the
frequency of replacement.
† For reassembly instructions, use the
reverse of the following disassembly
procedures.
† To facilitate atomizer removal from
hose manifold, a robot program should
be made that purges all paints and sol-
vents from the MMA-570. 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 “Mainte-
nance” section of this manual should be
lubricated with a food grade petroleum jel-
ly or with A11545 lubricant.
† Direct Charge and Indirect Charge At-
omizer removal instructions are the same
with the exception of removing the high
voltage ring.
NOTE

!
† Prior to removing applicator from the ro-
bot, 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.
Disassembly the turbine manifold assembly from
the mounting manifold assembly by unscrewing the
retaining ring counter-clockwise. Use of the span-
ner wrench to aid in removal may be necessary.
Once the high voltage ring and turbine manifold
assembly have been disassembled, remove all
tube connections to the mounting manifold and
remove the four (4) mounting screws.
