3.06 Input And Output Wire Guide
Installation
Refer to Figure 3-2.
Install the input wire guide (the longer one) by loosening
the input guide lockscrew and inserting the guide into
the hole in the feedhead assembly. The recessed end of
the guide should be toward the wire spool. Adjust the
guide so that it is clear of the feed rolls and tighten the
input guide lockscrew.
Install the output wire guide in the same manner, with
the conical end toward the feed rolls. The tip of the conical
end should be as close to the feed rolls as practical.
Tighten the output guide lockscrew.
NOTE
Before tightening the input and output guide
lockscrews, install the drive roll to help in the
alignment of the wire guides.

the groove in use.
Feed rolls are removed by twisting the feed roll retainer
cap and aligning the retaining knob splines/tabs with the
drive gear splines. Feedrolls are installed by putting the
feedroll onto the drive gear splines and twisting the
feedroll retainer cap so that the splines/tabs rest against
the face of the feedroll where they will click into place.

Installation of all styles of feed rolls for this
feeder is identical.
