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.
On pistol grip models it may be
easier to replace the collet nut
with the liner conduit removed
from the gun housing block.
