REMOVING SPRAY
APPLICATOR FROM THE
REAR MANIFOLD
ASSEMBLY
(See Figure 12)
Anytime service is required within the applicator
shroud, the applicator should be removed from the
robot mounting plate assembly. After the appli-
cator is removed from the robot, always move to
a clear, clean work area to remove the applicator
shroud and begin servicing.
1. Purge all fluid from the system and blow lines
dry with pushout air before the applicator is re-
moved.
2. All pressures must be removed, both air and
fluid, before removing the applicator. Fluid pres-
sure can be removed by actuating the applicator
trigger with the fluid regulator open.
3. Turn off the power supply to the applicator.
4. Remove applicator from robot by turning the
retaining ring [6] counter-clockwise from the
manifold robot mounting plate [2] (see Figure 12).
5. Remove spray head [5] (Figure 12) as previ-
ously described in Figure 10a.

6. Remove the four (4) screws [7] from mounting
block [3] and pull the block out of the upper man-
ifold [4] as shown in Figure 12.
7. Remove and inspect the o-rings [2, 16, and 17]
on the upper manifold [18]. Replace if necessary
(see Figure 13).
8. Remove mounting ring [6] by pulling straight
up as shown in Figure 13.
9. Remove the five (5) screws [8] from the bottom
of the mounting plate [12] (see Figure 13).
10. Remove the break-away ring [9] from the
mounting plate [12].
11. Pull down on the shroud [10] and slip it off
the applicator assembly to reveal the internal
assembly components. It may be necessary to
carefully use a flat head screwdriver between the
shroud [10] and the upper manifold [18] to pry the
two apart.
12. Remove the five (5) air bolts [7] from the bottom
of the mounting plate [12]. Inspect the five (5)
o-rings [3] located within the air bolts [7] and re-
place if necessary.
13. Remove the coil fluid tube [5] by unscrewing
the fluid fitting [4] from the valve manifold block
[11].
14. Remove the cascade plug [19] from the mount-
ing plate [12] by unscrewing the set screw located
on the side of the mounting plate [12] in-line with
the timer markings. (For set screw location see
Figure 14).
15. Slide the valve manifold block [11] and mounting
plate [12] off of the support rods [1] (see Figure 13).
16. Unscrew the five (5) support rods [1] from
the upper manifold [18] using an A11284-00 tool.
17. Remove the cascade [19] from the upper man-
ifold [18] by pulling straight down on the cascade
[19] (see Figure 13).
18. Remove the coil fluid tube [5] from the upper
manifold [18] by unscrewing the fluid fitting [4].
19. Remove the mounting plate [12] from the valve
manifold block [11] by unscrewing the three (3)
screws [13] located on the bottom of the mounting
plate [12].
20. Reassemble in reverse order making sure to
align the cascade wire plug timing mark with the
timing mark on the mounting plate [12] as shown
in Figure 14. Remember to tighten the set screw
called out in Figure 14.
21. When placing the shroud [10] back onto the
assembly, make sure to mate the edge with the
lip on the shroud [10] with the upper manifold [18],
and fit the lip of the shroud [10] into the groove on
the upper manifold [18], as shown inf Figure 13.
