Ransburg Evolver 303 Dual Purge Solvent Robotic Applicator A12374-XXX - Manual (Page 46)

REMOVING SPRAY APPLICATOR
FROM THE REAR MANIFOLD
ASSEMBLY
(See Figure 15)
Anytime service is required within the applicator
shroud, the applicator should be removed from the
robot mounting plate assembly. After the applicator
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 pressure
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 re-
taining ring [6] counter-clockwise from the manifold
robot mounting plate [2] (see Figure 15).
5. Remove spray head [5] (Figure 15) as previously
described in Figure 13a.

(See Figures 15, 16, and 17)
6. Remove the four (4) screws [7] from mounting block
[3] and pull the block out of the upper manifold [4]
as shown in Figure 15.
7. Remove and inspect the o-rings [2, 19, and 20] on
the upper manifold [18]. Replace if necessary (see
Figure 16).
8. Remove mounting ring [13] by pulling straight up
as shown in Figure 16.
9. Remove the five (5) screws [11] from the
bottom of the mounting plate [12] (see Figure 16).
10. Remove the break-away ring [10] from the mount-
ing plate [12].

11. Pull down on the shroud [17] 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 [17] and
the upper manifold [18] to pry the two apart.
12. Remove the five (5) air bolts [9] from the bottom
of the mounting plate [12]. Inspect the five (5)
o-rings [3] located within the air bolts [9] and replace
if necessary.
13. Remove the coil fluid tube [7] by unscrewing the
fluid fitting [4] from the valve manifold block [15].
14. Remove the cascade plug [16] from the mounting
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 17).
15. Slide the valve manifold block [15] and mounting
plate [12] off of the support rods [1] (see Figure 16).
16. Unscrew the five (5) support rods [1] from the
upper manifold [18] using an A11284-00 tool.
17. Remove the cascade [16] from the upper manifold
[18] by pulling straight down on the cascade [16]
(see Figure 16).
18. Remove the coil fluid tube [7] from the upper
manifold [18] by unscrewing the fluid fitting [4].
19. Remove the mounting plate [12] from the valve
manifold block [15] by unscrewing the three (3)
screws [8] 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
17. Remember to tighten the set screw called out
in Figure 17.
21. When placing the shroud [17] back onto the as-
sembly, make sure to mate the edge with the lip on
the shroud [17] with the upper manifold [18], and
fit the lip of the shroud [17] into the groove on the
upper manifold [18], as shown in Figure 16.
