MAINTENANCE
!
† To avoid damage to the chevron seals, they
MUST be installed from the rear of the barrel.
1. Place conductive female chevron adapter onto the front
of shaft with the concave side toward the front.
2. Screw the four (4) chevron seals onto shaft, concave
sides forward (see Figure 17).
!
† 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 surface for
wear. If it is rough or uneven, replace it.
3. Place male nonconductive chevron adapter onto shaft
with the convex end rearward.
† The chevron adapters and chevron seals should
seat together to form an unbroken seal.
4. Screw needle/electrode onto shaft and hand tighten.
† Apply a light coating of dielectric grease to the
chevron seals and needle shaft.
!
† FAILURE to coat the needle shaft assembly MAY
CAUSE lower electrical output of the gun.
5. Fill the inner diameter of the packing tube with dielectric
grease.
6. Insert the needle shaft, rear section first, into the packing
tube. Rotate the needle shaft while moving back and
forth inside the packing tube until fully inserted.

7. With your finger, wipe the excess grease from both ends
of the packing tube. Using the excess grease, apply a
thin film to the outer surface of the packing tube and to
the external o-ring on the cartridge seal.
† Be generous with the dielectric grease when apply-
ing it to the packing tube and needle shaft. This helps
to remove air voids from this chamber. DO NOT apply
so much grease that it creates an air lock during as-
sembly of the gun.
8. Apply a light film of dielectric grease to the seal retainer
o-ring and install it into the external groove.
9. Insert the spring loaded u-cup seal into the seal retainer
(with the concave side facing outward). Use the short
end of the spacer to seat the seal.
10. While holding the rear seal retainer sub-assembly and
spacer together, place these components (with the
spacer rearward) onto the rear of the needle shaft and
slide them over the sealing area.
11. Place the six (6) spring washers onto shaft with the first,
third, and fifth ones concave (cupped) side forward. The
second, fourth, and sixth ones should be cupped side
rearward (see Figure 17).
† All six (6) spring washers MUST be replaced alternately
as shown in Figure 17, or the applicator will malfunction.
