SERVICE
Because we want to provide our users with the
most up-to-date technology possible, we are con-
stantly seeking to improve products. If a change
in product configuration occurs after it is on the
market, we will implement that technology in future
production and, if practical, make it available to
current users. The following service information is
based on standard specifications and procedures
for this product. If you find some minor deviations
between this information and your equipment
because of design or manufacturing changes,
contact your Ransburg representative to resolve
the difference.
>
An electrical discharge or spark may create
an electrical and/or fire hazard during main-
tenance. 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 hazard-
ous. Do not adjust or repair the spray applicator
when the robot is operating or waiting to start.
The robot must be locked out and tagged out
per OSHA prior to removing the applicator
from the robot manifold assembly.

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

!
>
Disassemble the spray head only
enough to remove and replace defective
parts. For instance, if only replacing the
front electrode it is not necessary to re-
move the fluid nozzle.
NOTE
>
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 [5] to seat fully
against mounting block assembly [3] (see
Figure 12).
>
To prevent damage, always lubricate
the o-rings located on the underside of
the spray head.
NOTE
>
Eye protection should be worn while ser-
vicing applicator.
