Ransburg REA Automatic Applicators 77359, 76110, 77140 - Manual (Page 34)

1. Place conductive female chevron adaptor onto
the front of shaft with the concave side toward
the front.
2. Screw the four (4) new chevron seals onto
shaft, concave sides forward.
NOTE
>
The chevron adaptors and chevron
seals should seat together to form an
unbroken seal.
BARREL REASSEMBLY
(REA 9000W)
• Clean all parts with a suitable non-polar
(non-conductive) solvent.
• If the electrode wire is bent, straighten it CARE-
FULLY by hand or use needle nose pliers.
• Check all parts for damage or wear. Replace
those that are damaged or worn with new
parts.
• Replace chevron seals with new parts.
• From time to time it is desirable to test the
electrical integrity of the LREA4001-00 resis-
tive electrode (see “To Test“ in the “Service
for 9000W” in the “Maintenance” section).

DO NOT over-tighten. Over-tightening may
result in stripped threads or cracked barrel.
C A U T I O N
!
> To avoid damage to the chevron seals, they
MUST be installed from the rear of the barrel.
C A U T I O N

DO NOT push the chevron seals straight
onto the shaft. The shaft threads may damage
the chevron bore and cause the applicator to
leak fluid.
> Inspect needle/electrode shaft sealing sur-
face for wear. If it is rough or uneven, replace it.
3. Place male nonconductive chevron adaptor
onto shaft with the convex end rearward.
4. Screw needle/electrode onto shaft and hand
tighten.
5. When replacing the needle/electrode on the
needle shaft of the REA 9000W applicator ONLY,
the electrode wire MUST be trimmed OFF flush
with the electrode body. Failure to do so may
allow the fluid supplylLine to become charged,
thus reducing available voltage at the external
probe electrode.
>
Apply a coating of dielectric grease
to the chevron seals and needle shaft.
NOTE
C A U T I O N
!
>
FAILURE to coat the needle shaft assem-
bly MAY CAUSE lower electrical output of the
applicator.
6. Insert the assembled items through the rear
barrel packing chamber of the barrel/cascade
assembly.
