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.
> 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.

SPRAY HEAD ASSEMBLY
Before performing any work on the spray applicator,
always flush the fluid passages and blow dry with
push-out air, and wipe the spray applicator clean.
Refer to "Gun Cleaning/Service" 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.
Rear Needle Replacement
(See Figure 5)
1. Remove the air cap, fluid tip, and the fluid
nozzle as described in Steps 1 through 13 of the
"Gun Cleaning/Service"" in the "Maintenance" sec-
tion.
2. Remove the rear needle [6] and lock nuts [4]
and [5] as an assembly. Pull the assembly out
from the rear of the spray head.
> 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.
