If gun is a 15 ft (4.5 m) model,
push the split end of liner
through until the opposite end
is sticking out of the gun con-
nector 1 to 2 inches (2.5 to 5
cm). After trimming, the section
with the split on it can be saved
to use as another replacement
liner.
Cut off split portion of liner. Replace
front collet nut with new plastic nut
from the liner kit. Reinstall steel nut
at gun connector and tighten onto
liner.

May be easier to replace the
collet nut with the liner conduit
removed from the gun housing
block.
The liner end will not stick out of the
plastic collet nut supplied with the
liner kit.
At the gun connection end, cut liner
as close as possible to control
(push motor) drive rolls.

structions on rethreading wire.
