SECTION 4—REMOVING AND REPLACING OF UPPER PLATE:
Removal of this part is necessary to; change the Twister Assembly, clean debris from under the Upper
Plate, change the Needle Left and Needle Right, change the Needle Guard Arm Spring, change the
Needle Guard Arm, and to do any other service required on parts located between the Upper Plate and
Middle Plate.
To remove the Upper Plate:
1) Remove the Top Cover as per the instructions in Section 1.
2) Locate the Micro-Switch. See Figure 9.
3) Pull the 2 wires off the Micro-Switch. These wires are connected to the Micro-Switch with push on
connectors.
4) Unscrew the 2 screws holding the Micro-Switch and place the whole assembly to the side.
5) Locate the screw holding the Green and Yellow Ground Wire. See Figure 9. Remove the screw and place
the screw to the side.
6) Locate the screw holding the Switch Lock Lever Spring assembly. See Figure 9.
7) Unscrew the screw and remove the assembly.
Suggestion:
To remove this assembly without the spring
recoiling and scattering the parts, loosen the screw about half way, locate the short leg of the spring which
will be pressed up against a post behind the Micro-Switch. Using a long nose pliers, grab the short leg of
the spring and remove it from the post. This will release the pressure from the spring. Then continue un-
screwing the screw and removing the assembly. Place the assembly intact to the side.
8) Remove the Arm Spring. See Figure 9.
9) Locate the Tie Feeding Roller Arm. See Figure 9.
10) Locate the Screw and remove the Tie Feeding Roller Arm.
11) Below the Tie Feeding Roller Arm locate the Tie Feeding Roller with Bushing.
12) Place the Tie Feeding Roller with Bushing to the side.
Suggestion:
The bushing inside the Tie Feeding
Roller with Bushing has a shoulder, this shoulder must always be on top. When placing it down to the
side, place it in the same orientation as it is used in the machine so that when it is re-installed, the bushing
will be in the right direction.
13) Follow the instructions in Section 3 to remove the Segment Gear and Feeding Roller. Steps 6 and 7 will
not be required as these parts have already been removed.
14) Locate the Movable Blade Holding Spring holding the Movable Blade in position. Release pressure on the
Spring by removing it from the Spring Hanger on the linkage. See Figure 4. The Cutter Blade Linkage
does not have to be removed to remove the Upper Plate.
15) Remove the 6 screws shown in Figure 10.
Suggestion:
Loosen the screws, but do not physically remove
them from the machine. Once they are loose, the Upper Plate can be removed, and the screws will be in
the right place during re-assembly.
16) Lift up the Upper Plate. Note: The Movable Blade is may still be connected to the Cutter Blade Linkage.
When lifting the Upper Place do so carefully as not to disturb this positioning. If the position is disturbed,
it can be reset with the Upper Plate off.
See Figure 9 and Figure 10 on the next page.
