REMOVAL, INSTALLATION AND TRIMMING
INSTRUCTIONS FOR MAGNUM
® LINERS
NOTE: The variation in cable lengths prevents the
interchangeability of liners. Once a liner has been cut
for a particular gun, it should not be installed in anoth-
er gun, unless it can meet the liner cut off length
requirement. Liners are shipped with the jacket of the
liner extended with the proper amount.

connection. Remove cable from robot.
2. Lay gun and cable out straight on a flat surface.
3. Loosen set screw located in the brass feeder con-
nector using 5/64 (2.0 mm) Allen wrench. Pull liner
out of cable.
