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.
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 count-
er-clockwise.

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 ad-
justment nut can be reinstalled for additional grip.
If the needle shaft will not pull out of the barrel,
use the following procedure.
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.
† The six (6) spring washers will come
off the needle shaft assembly at this point.
NOTE
† During this operation, be CAREFUL that
the interior surface of packing chamber is
NOT damaged (marred or scratched)! This
chamber is a seal area and the barrel/appli-
cator assembly will have to be replaced if it
is damaged.
† DO NOT lose any of the spring washers!
The gun MUST have all six (6), correctly po-
sitioned, in order to function properly!
