The plastic Belt Guard (7676) must be
removed before the M27 can be turned
over manually. To remove the Belt Guard,
remove the Retaining Screw (G30163)
from the top of the Guard (on BST mod-
els only). Press on one side tab while
prying out the locking face, at the top of
the Guard. Next, pull down slightly on
the top of the Guard to release the bottom
tab. The Guard will now be free to lift off
from around the Belt Guard (7675).
To reassemble, interlock the bottom
tab and pull up slightly on the Guard to
interlock the side tab, then squeeze
the two halves of the Guard together
to lock the remaining tab. Reassemble
the retaining screw at the top of the
Guard (on BST models only).

(7690) from the Spool Stud. Slide the Wire Spool over the Spool Stud, making sure that the Flat Washer
(PG10271) is between the Spool and the Wire Spool Bracket. Also verify that the wire payoff is
identical to the payoff in Figure 1; from left to right. Improper wire payoff will result in poor stitch-
ing. Slip the Plastic Washer (M11009) over the Spool Stud and replace the Tension Spring and Set Collar.
Apply slight pressure on the Set Collar, pre-loading the Tension Spring, then tighten the Thumb Screw in
the Set Collar until secured in position. A properly set Tension Spring will cause the Wire Guide Spring
(15150A or 18150A) to flex but not actually hit the wire spool. The Tension Spring is designed to prevent
the Wire Spool from over-running and tangling the wire.
Remove the assemblies from the complete Work Table Assembly (17145FA): the Right-Hand Side
Paper Guide (A1178), the Left-Hand Side Paper Guide (A1185), four (4) Work Guide Screws (63), the
Back Gauge Bar Assembly (17161A), the Back Stop Gauge (G30164A) and the Plate (17149). Center
the Table Assembly over the Clincher Rail of the machine and secure the Table with the two (2) Pins
(16148). Once the Table is secured, insert the Pivot Rod (17146) through the Table and Clincher Rail.
You may have to use a soft hammer to completely insert the Rod.
Note: Be sure to loosen the two (2) Set Screws (38) before attempting to insert the Pivot Rod.
