Ransburg MMA-570 Direct_Ind Charge Atomizer A13366 - Manual (Page 50)

VIBRATION NOISE
If the MMA-570 is vibrating or making an unusually
loud noise, it usually means there is an imbalance
situation. The atomizer bell cup may have dried
paint on it or the bell may be physically damaged.,
or there may be paint trapped between the bell
cup and shaft preventing the bell cup from properly
seating. If any of these conditions exist, they MUST
be corrected. Excessive imbalance caused by one
of the conditions may result in bearing damage
and turbine failure. Warranty DOES NOT cover
failure caused by imbalanced loading conditions.
To determine if the bell is dirty or damaged, remove
the bell cup and turn the turbine ON. If the noise
is eliminated, the bell cup is the problem. If the
noise continues, the turbine may be damaged
and should be inspected. Excessive air required
to achieve same speed may indicate a faulty or
contaminated turbine. DO NOT continue to operate
a noisy turbine.

† NEVER wrap the applicator in plastic to
keep it clean. A surface charge may build
up on the plastic surface and discharge to
the nearest grounded object. Efficiency of
the applicator will also be reduced and dam-
age or failure of the applicator components
may occur. WRAPPING THE APPLICA-
TOR IN PLASTIC WILL VOID WARRANTY.
To reduce the risk of fire or explosion, OSHA
and NFPA-33 require that solvents used for
exterior cleaning, including bell cleaning
and soaking, be nonflammable (flash points
higher than 100°F/ 37.8° C). Since elec-
trostatic equipment is involved, these sol-
vents should also be non-polar. Examples
of non-flammable, non-polar solvents for
cleaning are: Amyl acetate, methyl amyl ac-
etate, high flash naphtha, and mineral spirits.
† Do not use conductive solvents such as
MEK to clean the external surfaces of the
MMA-570 without a second cleaning with a
non-polar solvent.
† When using a rag to hand wipe the
MMA-570, the turbine air should be off, but
leave both the shaping air and bearing air
turned on. Ensure that rotation has come to
a complete stop.
TURBINE MAINTENANCE
DO NOT attempt to rebuild the turbine. Any
endeavor to disassemble a turbine during the
warranty period will void the warranty. The turbine
is non-field serviceable. Contact your authorized
distributor or Ransburg for instructions.

† If a bell cup comes off a rotating shaft be-
cause of motor seizing or any other reason,
the atomizer and bell cup must be returned
to Ransburg for inspection and evaluation to
determine if the bell can be used in operation.

MMA-570. Turbine drive air must be off, but
leave bearing air on. The shaping air should
have approximately 70 slpm air flow through
each to prevent the solvent from entering
these passages.
• Do not spray the MMA-570 unit with a solvent
applicator used for cleaning. The cleaning fluid
under pressure may aid conductive materials
to work into hard to clean areas or may allow
fluids to be forced into the turbine assembly.
• Do not reuse an atomizer bell cup that shows
any sign of damage such as nicks, heavy
scratches, dents, or excessive wear.
• Always final wipe all parts with a non-polar
solvent and wipe dry (high flash Naphtha, etc.).
