Before the Stitcher Machine is turned on, release the Wire Holder Assembly [070135A] (Not
shown-See Fig. 7) secured by the Wire Holder Retaining Spring [070183 or 070583] by loosening
the Screw [072004] on the front of the head. Thread the wire from the Spool under the studs on the
Wire Guide Spring (070286), between the Wire Oiler Felts [G20293] on the Spring and into the
Wire Nozzle [070181]. Turn the Feed Release Handle [070119)] clockwise so that the Small Feed
Gear [070112] is disengaged from the Large Feed Gear [070510A].
Continue to push wire through the Replacement Head until the end of the wire passes the Small and
Large Feed Gears, enters the Wire Tube [070544] and begins to come out the bottom of the wire tube.
Then using a small screw driver, wedge the wire up until it enters the Fixed Wire Cutter [070600C].
Engage the Small and Large Feed Gears by turning the Adjustable Lever counter-clockwise.
Note: It will take two full cycles for the proper length staple to come out of the head.
