5. To remove the wire from the EMP unit cut the wire just before entry into the wire-
feed assembly. Be sure to hold the bobbin-end of the wire before cutting to restrain
the wire from unravelling from its spooling on the bobbin. Secure the bitter end by
any convenient means to the wire frame of the bobbin to mechanically restrain it
while this procedure continues.
6. Disconnect the torch assembly from the EMP unit by loosening the torch connector
holding knob and disconnecting the torch connector.
7. Pull the remaining length of the wire through the wire-feed assembly and, with the
torch, set the torch assembly aside (with the loose wire still installed in the torch).
The old wire should now be completely removed from the wire-feed assembly.
8. Remove the torch assembly from the EMP unit and remove the remainder of the old
wire still in the torch assembly and properly dispose of it. The torch assembly will be
re-connected near the end of this procedure.
9. REMOVE WIRE-FEED ROLLERS:
a. See Section 6.11 REMOVING/INSTALLING WIRE-FEED ROLLERS: steps for
