External Atomizer Surface Cleaning
W A R N I N G
> To reduce the risk of fire or explosion,
OSHA and NFPA 33 require that solvents used
for exterior cleaning, including disk cleaning
and soaking, be nonflammable (flash points
higher than 100 o F/37.8 o C). Since electrostatic
equipment is involved, these solvents should
also be nonpolar. Examples of nonflammable,
nonpolar solvents for cleaning are: Amyl acetate,
methyl amyl acetate, high flash naphtha and
mineral spirits.
> Do not use conductive solvents such as MEK to
clean the external surfaces of the Turbodisk 2.
> Never lower the Turbodisk 2 assembly into a
drum for flushing or color changing.

Disk Cleaning
Normally, the internal cleaning instructions will
suffice to clean the disk. If flushing the disk does not
remove all the residue, the disk may be removed for
hand cleaning. Unscrew mounting nut and remove
the disk by using the supplied disk puller.
Inspection of the disk is required to determine if
wear to the serrated edge or damage has occurred.
Wear can cause a reduction in transfer efficiency and
excessive paint wrap on the atomizer fairing.
> The turbine shaft must be held with a
7/16” open end wrench while using the disk
puller.
NOTE
W A R N I N G
> Do not hold disk edge during removal. This
could result in injury.
!
Clean the disk by soaking in an appropriate solvent
to loosen paint residue. Do not soak for more than a
24 hour period. Use a soft cloth to remove the paint
from the surface and a soft bristle brush to remove
paint from the well area. The splash plate may need
to be removed to clean the paint well. The screws
must be retorqued to 24 lb • in after cleaning.
Reinstall the disk and torque the mounting nut to
50-60 lb • in.
W A R N I N G
> Do not attempt to clean the disk edge while
it is rotating. Do not attempt to slow down or
stop the disk by holding a rag or a gloved hand
against the edge. This could cause physical harm
and/or damage to the disk.
!
> Do not use abrasive materials which will
scratch or damage the disk. Cleaning pads such
as Scotch-Brite® should not be used.
> Using an atomizer disk with paint buildup may
cause an imbalance. This may result in bearing
damage and turbine failure. This condition
may also stress the disk when operating at high
speeds.
> Before reinstalling the disk onto the shaft,
check and clean the tapered mating surface for
paint residue.
> Care must be taken when mounting the disk
assembly to the motor shaft. The mounting nut
should turn freely for several turns until it fully
bottoms on the disk assembly.
