4.
Release the tensioning arm by pulling the tension knob up out of its detent and
rotating it toward you, (see 1 in Figure 14). Since the wire-feed pressure must be
disturbed to release this arm, the tension on the rollers will have to be re-adjusted in a
later step. The tensioning arm (2) is spring-loaded. It will pop-up when the tension
knob in the previous step is rotated out-of-the-way.

Remove the wire from the wire-feed mechanism.
CAUTION!
When removing the drive roller (roller located on left side) be careful
not
to
remove the drive gear with it. Doing so risks losing the small woodruff key on
the motor shaft. Failure to comply will render the entire unit useless until this
part is replaced.
6.
Remove the two wire-feed rollers by removing their thumb screws and sliding each
roller from their shaft (see Figure 15 and 16).
