Evolver Solventborne Robotic Atomizers - Maintenance
SERVICE
Because we want to provide our users with the most
up-to-date technology possible, we are constantly
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 manufac-
turing changes, contact your Ransburg representative
to resolve the difference.
>
An electrical discharge or spark may create an
electrical and/or fire hazard during maintenance.
Do not service the spray gun 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 gun when
the robot is operating or waiting to start. The
robot must be locked out and tagged out per
OSHA prior to removing the gun from the robot
manifold assembly.

Before performing any work on the spray gun, always
flush the fluid passages and blow dry with pushout air,
and wipe the spray gun clean. Refer to "Gun Clean-
ing" in the "Maintenance" section for instructions on
how to properly clean the spray gun. Depressurize
all fluid and air pressures before removing the gun
from its manifold. Always work in a clear, clean space
to minimize parts 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 spray head only enough
to remove and replace defective parts.
For instance, if only replacing the front
electrode it is not necessary to remove 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 [2] to seat fully against mounting
block assembly [3] (see Figure 10).
>
To prevent damage, always lubricate the
o-rings located on the underside of the
spray head.
NOTE
>
Eye protection should be worn while servic-
ing gun.
