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.
