14. Adjust in/out position of folder by extending the horizontal cylinder all the way. Loosen base
mounting screws and move whole assembly to align the centers of the folder blades with center
line of the machine. To square the assembly, you might need to loosen the 4 screws that mount to
the horizontal cylinder. See “Figure 7” on page 90.
15. (Turn air OFF) Adjust the folder up/down on the vertical base. Insert 3/16" Allen wrench under
bottom of cylinder as shown, then loosen all 3 sets of adjusting screws. Holding the cylinder
squarely against the wrench, tighten the #1 set of adjusting screws, then the #2 set of adjusting
screws. Finally, holding the nut plate firmly against the bottom of the cylinder tighten the #3 set
of adjusting screws. See “Figure 8” on page 91.
16. Adjust folding blades up/down and in/out. Insert the 13" long handle piece into the tunnel and
lower the blades under pressure (in manual screen 4) send blades in, loosen the vertical
adjustment screws on the blades and press them firmly against the bottom of the folded handle.
Also make sure that the rear edge of the groove in both blades align with the fixed wall of the
tunnel and tighten the adjustment screws. Check blade alignment by taking the handle out and
extending the blades. Both blades should be parallel to center blade. See “Figure 13” on page 96.
17. Adjust folder blade up/down cylinder. Down position is fixed. To set the up position, adjust stop
screws so the bottom of the folding blade is even with the top of the tunnel. See “Figure 9” on
page 92.
18. Set the “in” position of the folder blade cylinders by adjusting cylinder stop screws to a height of
7/16". See “Figure 9” on page 92.
19. Position blade cylinders in their mounting slots so that when the blades are “in” there is a gap of
1/16" between the inside wall and the center blade that the handle is folded around. When the
blades are extended, they should clear the center blade by 1/8". See “Figure 10” on page 93.
20. Adjusting the handle tunnel. Adjust the side gate of the handle to be vertical when closed. Also
adjust the gate to be parallel to the edge of the center blade. Insert a 13" section of handle into
the tunnel. Insure that the back wall of the tunnel is parallel to the edge of the center blade. Using
the noted screws, adjust the “v” notch in the folder plate so that it aligns with vertical center line
of the stitching clamp. See “Figure 11” on page 94.
21. Adjust top clamps up/down. Loosen 3 screws on the top clamp mounting bracket and adjust the
clamps in/out. Adjust the top clamps so that the blocks on the bottom of them line up with the
fixed edges of the tunnel. See “Figure 12” on page 95.
22. Next, adjust the clamp up/down. The clamps must be adjusted so the blocks on the bottom are
not touching the center blade. With the screws loose, place a .015 shim under the blocks and
tighten the screws. There must be at least .005 gap still left after tightening the screws. See
“Figure 12” on page 95.
23. Adjust the handle cutter assembly in/out so there is 1/16 gap between it and the extended folding
blades. See “Figure 14” on page 97.
24. Adjust up/down so the bridge is 1/8" above the center folder blade with central folder blade at
the top of it travel. See “Figure 15” on page 98.
25. With the top handle roller cylinder extended, adjust the top roller so that is just lightly touches
the bottom roller.
26. Adjust bridge so that its bottom edge is 1/64" above the lower knife blade.
27. Adjust spool indexer. Adjust it side to side on cam followers and front and back on rear slots.
Level the spool carriage and make sure bridge slides easily in all positions.
28. Adjust locking pin on the roller cylinder to contact tapered hole in the spool frame without
moving it.
29. Make sure all spool rollers spin true and free. Also make sure that the small rollers toward the
front of the assembly spin free.
