Ransburg RMA Dual Purge Direct A12300 - Manual (Page 58)

MAINTENANCE
In addition to the above Warning, which relates
to potential safety hazards, the following infor-
mation must be observed to prevent damage to
the equipment.
CLEANING PROCEDURES
W A R N I N G
!
† Electrical shock and fire hazards can
exist during maintenance. Micro-Pak
supply must be turned off before en-
tering the spray area and performing
any maintenance procedures on the
atomizer. Spray booth fans should re-
main on while cleaning with solvents.
† Never touch the atomizer bell while it
is spinning. The front edge of the bell can
easily cut into human skin or cut through
gloves and other materials. Be sure the
atomizer bell has stopped spin-ning be-
fore attempting to touch it. Approximate
time for the bell to stop spinning after turn-
ing off turbine drive air is three minutes.
† Insure high voltage is off during any
cleaning procedure.

† DO NOT immerse the RMA-303 turbine in
solvent or other liquids. Turbine components
will be damaged and warranty will be voided.
† Bearing air must be on during all clean-
ing procedures to protect the air bearing
components.

O-RINGS
All o-rings in this atomizer are solvent proof ex-
cept the ones on the air bearing spindle. These
o-rings must not be soaked in solvent; if these
are exposed or soaked in solvent, they must
be replaced. These o-rings are engineered to
provide a fit between the air bearing spindle and
it's mating parts to reduce or eliminate harmonic
resonance (vibration).
Some o-rings are encapsulated. These o-rings
have a limited amount of stretch and will not return
to their original diameters if over-stretched. These
o-rings are subject to being distorted more easily
than rubber o-rings, so it is important that they
be sufficiently lubricated when mating parts are
installed onto them. They also will take a square
set over time and should be replaced periodically
if mating parts are removed repeatedly or if a new
mating part is installed onto them.
Any o-ring that is cracked, nicked, or distorted
must be replaced.
A suitable lubricant is food grade petroleum jell or
A11545-00 Petrolatum Jell.
