• Ground all operators by requiring that they hold
the applicator handle with a bare hand.
• Ground operators and all other persons in
spray areas by requiring that they wear conduc-
tive soled shoes or grounding straps.
• Have exhaust fans operating while spraying.
• Exhaust fans must be interlocked with the
control unit or Aviator.
• See that no more than one gallon of solvent per
safety container per operator is inside of the
hazard location.
• If ANY symptom of improper operation occurs,
suspend use of the unit until the problem has
been diagnosed and corrected. See "Trouble-
shooting Guide" or contact your authorized
ITW Ransburg representative.
• Ground MUST be maintained during the addition
of fluid to any supply container! Whenever
transferring flammable fluid from one container
to another, both containers MUST be properly
connected to a proven ground first and then to
each other. Personnel executing such a
transfer MUST also be grounded.
• A chemical reaction, resulting in the possibility
of a pressure EXPLOSION, may occur if 1, 1,
1-Trichloroethane, Methylene Chloride, or other
Halogenated Hydrocarbon Solvents are used
in PRESSURIZABLE FLUID SYSTEMS
having ALUMINUM or GALVANIZED
WETTED PARTS. Such an explosion could
cause DEATH, serious BODILY INJURY and/
or substantial property damage. Consult your
fluid supplier to determine the chemical content
of your solvents. (See "HHC Explosion Hazard
Danger Sign" and "Halogenated Hydrocarbon
Safety Bulletin".)
• Never flush the applicator with solvent while
electrostatics are on. Failure to turn off
electrostatics while flushing may cause an
IGNITION HAZARD.

Following are some basic electrostatic spray
techniques. Depending on the spray target, it may
be necessary to adjust the technique.
Spray Width Determination Spray Width Determination
Spray Width Determination Spray Width Determination Spray Width Determination
The size of the object being coated is the
determining factor in adjusting the spray pattern.
The larger the object, the larger the required pattern
width. This is accomplished by fluid nozzle
selection. Air adjustment is used to remove "tails"
from the spray pattern and adjust the pattern size.

The distance between the applicator and the target
influences the appearance of the final finish of the
object. If the applicator is held too close, under
100mm (approximately 4-inches), runs and sags
with excessive "bounce-back" may occur. If the
applicator is held too far from the object, the
electrostatic attraction is decreased. Normally,
the best spacing between applicator and target is
in the 150mm to 300mm area (6-inch to 12-inch).

The degree of atomization is depen-
dent on the viscosity of the paint formula-
tion, the applied fluid pressure, and nozzle
selection.
