Flex the cable over its entire length and again blow
out the cable. Repeat this procedure until no further
dirt comes out. If this has been done and feed prob-
lems are experienced, try liner replacement, and refer
to trouble shooting section on rough wire feeding.

LINER REMOVAL, INSTALLATION AND TRIMMING
INSTRUCTIONS FOR MAGNUM 350MP
NOTE: The variation in cable lengths prevents the
interchangeability of liners between guns. Once a liner
has been cut for a particular gun, it should not be
installed in another gun unless it can meet the liner
cutoff length requirement. Liners are shipped with the
jacket of the liner extended the proper amount.
1. Remove the gas nozzle.
