• Ground all operators by requiring that they
hold the gun handle with a bare hand.
• Ground operators and all other persons in
spray areas by requiring that they wear con-
ductive 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 Figure 1
"Troubleshooting Guide" or contact your au-
thorized ITW Ransburg representative.
• Ground MUST be maintained during the addi-
tion of fluid to any supply container! When-
ever transferring flammable fluid from one con-
tainer 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 WET-
TED PARTS. Such an explosion could cause
DEATH, serious BODILY INJURY and/or
substantial property damage. Consult your
fluid supplier to determine the chemical con-
tent of your solvents. (See SL-81-05 "HHC
Explosion Hazard Danger Sign" and SL-81-08
"Halogenated Hydrocarbon Safety Bulletin".)
• Never flush the gun with solvent while electro-
statics are on. Failure to turn off electrostatics
while flushing may cause an IGNITION HAZ-
ARD.
> The degree of atomization is depen-
dent on the viscosity of the paint formula-
tion, the applied fluid pressure, and nozzle
selection.

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 deter-
mining factor in adjusting the spray pattern. The
larger the object, the larger the required pattern
width. This is accomplished by fluid nozzle se-
lection. Air adjustment is used to remove "tails"
from the spray pattern.

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