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.
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.

chamber is a seal area and the barrel/cas-
cade assembly will have to be replaced if it is
damaged.
† DO NOT lose any of the spring washers!
The applicator MUST have all six, correctly
positioned, in order to function properly!
