10. Apply Loctite Primer T-602 “Locquip” #747-56
and Loctite #222 Medium Strength, (purple) to the
threads of piston [2] before reassembly. Allow
assembly to set (with piston end down) for at least
3 hours prior to use. Apply a thin film of petroleum
jelly to all o-rings [4, 5 and 6] before reassembly.
Apply petroleum jelly to the inner surface of both
ends of spool valve body [1] before reassembly.
11. Referring to Figure 15, reassemble cartridge
valve [16]. Lubricate bore of valve manifold with a
thin film of petroleum jelly. Insert cartridge valve
back into valve manifold housing [1].
12. Examine valve cover o-rings [20 and 21] for
any damage. Replace is necessary.
13. Apply a thin film of petroleum jelly to o-rings [20
and 21] before reassembling.
14. Use three small metal socket head cap screws
[6] to attach valve cover assembly [2] back to
valve manifold housing [1].
15. Replace two air fittings [3] using care not to
damage the plastic threads.

1. Referring to Figure 6b, remove flange [8] from
the applicator shroud by loosening three slotted
dog style set screws [6].
2. To remove applicator shroud [3], pick up the
applicator assembly, place the two locating pins
projecting from the applicator manifold plate onto
a rigid surface. Grasp the shroud in both hands
and firmly push downward. The shroud will slide
off of the valve manifold assembly.
3. Referring to Figure 16, remove three metal
socket head cap screws [11] and o-rings [12]
holding applicator manifold plate assembly [5] to
tie rods [3 and 7].
> Press against locating pins only. Pressing
against fluid fittings could cause damage.

4. Remove nylon socket head cap screw [10]
holding L-shaped bracket [6] to the valve cover
assembly, and set aside. Remove two screws [9]
holding the bracket to short tie rod [7] and set
aside.
5. Referring to Figure 12, disconnect air
atomization tube [6] and fan air tube [8] from air
fittings [3] (see Figure 15) on either edge of the
valve cover assembly.
6. Remove two air fittings [3] (see Figure 15).
7. Remove three small metal socket head cap
screws [6] (see Figure 15). This enables valve
cover assembly [2] (see Figure 15) to be
removed.
8. Referring to Figure 15, thread a #8-32 screw
into the threaded hole at the center of valve piston.
Pull screw, enabling the cartridge valve assembly
[16] to come out.
9. Referring to Figure 7, check valve piston [2] for
free movement and the four o-rings for damage or
wear. One of the o-rings [5] is located on the valve
piston within the assembly. Use two screwdrivers,
engaged into the slots on both ends of the
assembly, to disassemble. Replace any damaged
o-rings.
> When applying Loctite, use very
sparingly. Apply one small drop to first
thread of [2], then carefully assemble. Do
not get any Loctite on ID of [1] or OD of [2],
Figure 7. Cartridge valve may malfunc-
tion.
