> An electrical discharge or spark may create
an electrical and/or fire hazard during mainte-
nance. Do not service the spray applicator
with the power supply on. Verify that the
power supply on/off switch has been turned
off.
> Unexpected robot movement can be haz-
ardous. Do not adjust or repair the spray
applicator when the robot is operating or wait-
ing to start. The robot must be locked out and
tagged out per OSHA prior to removing the
applicator from the robot manifold assembly.

> As the spray head is removed from the
valve manifold assembly, a certain amount of
residual fluid may be present. Care must be
taken not to allow this fluid to drain into the high
voltage terminal rings or air passages.

> In any disassembly or reassembly
procedure involving o-rings, care must
be taken not to lose them. O-rings (gray
color) are very expensive; always reuse
them unless they are damaged.
> Disassemble spray head only enough
to remove and replace defective parts.
For instance, if only replacing the front
needle it is not necessary to remove the
fluid nozzle.

> At assembly, apply a small amount of
dielectric grease to grooves in spray head
and valve manifold to reduce high voltage
breakdown. Excessive grease will not
allow Spray Head [1] to seat fully against
Applicator Housing Assembly [2]. (See
Figure 6b.)

Before performing any work on the spray applica-
tor, always flush the fluid passages and blow dry
with pushout air, and wipe the spray applicator
clean. Refer to "Applicator Cleaning", earlier in the
"Maintenance" section, for instructions on how to
properly clean the spray applicator. Depressurize
all fluid and air pressures before removing the
applicator from its manifold. Always work in a
clear, clean space to minimize parts loss and
damage.
