4. Remove trigger from the applicator handle.
5. Using an adjustable wrench, unscrew the fluid tube
connector from the barrel and slide it down the fluid
tube. The fluid tube must be removed prior to removing
the barrel to prevent damage to the cascade.
6. Use the special multi-purpose wrench to loosen the
retaining nut that secures the barrel to the applicator
handle. After unscrewing the nut, slide it forward onto
the barrel.
7. Hold the applicator handle and fluid tube so the barrel
points downward. With the other hand, pull the barrel
forward to separate it from the handle. Once the barrel
has cleared the handle, remove the spring from the
spring retainer and set it aside.

DISASSEMBLY/REASSSEMBLY
OF BARREL WITH THE 2K FLUID
NEEDLE PACKINGS
Disassembly
1. Remove the trigger adjustment nut and spring retainer
from the needle shaft using two 3/8" open-end wrenches.
2. Position the barrel so the front is facing down. Using the
small spanner tool on the special multi-purpose wrench,
unscrew the packing nut from the rear of the barrel by
turning it counter-clockwise.
8. There is no need to remove the retaining ring or nut from
the barrel unless they are damaged. If they are to be
replaced, lift one end of retaining ring over the captive
ridge and spiral it off the end of the barrel. Then the
retaining nut can be removed.
Use care in removing the retaining ring. If it is
spread too much it could break.
Figure 23: Removal of Needle Shaft
NOTE
3. Hold the barrel in one hand and with a firm pull, remove
the needle shaft assembly from the packing chamber of
the barrel. The trigger adjustment nut can be reinstalled
for additional grip. If the needle shaft will not pull out of
the barrel, use the following procedure.
The six (6) spring washers will come off the
needle shaft assembly at this point.
a. Remove the needle/electrode from the
needle shaft.
b. Pull the needle shaft from the rear of the barrel.
c. Place the barrel on a work bench. Holding
the barrel in one hand, with the front pointing
upward, push a 5/16-inch diameter wooden or
plastic dowel rod, down through the center bore
of the barrel. This should push all of the packing
chamber parts out the rear of the barrel.
CAUTION
!
During this operation, be
CAREFUL
that the in-
terior surface of packing chamber is
NOT
damaged
(marred or scratched)! This chamber is a seal area
and the barrel/cascade assembly will have to be re-
placed if it is damaged.
DO NOT
lose any of the spring washers! The ap-
plicator MUST have all six, correctly positioned, in or-
der to function properly!
