SECTION 7—REMOVING AND REPLACING OF BOTTOM PLATE:
To remove the Bottom Plate:
1) Follow the instructions in Section 6 To Remove the Twisting Head Assembly from the Base of the
machine.
2) Turn the Twisting Head Assembly over so that the Bottom Plate is facing up.
3) Locate the Main Shaft Gear
4) Using a 2mm Allen Wrench, loosen the Set Screw located on the side of the Gear. There is a hole in the
shaft that the Set Screw lines up with, so the screw may need to be backed out of the Gear almost all the
way prior to lifting the Gear.
5) Remove the Main Shaft Gear from the Shaft. This may require the use of a pair of pliers to grab the gear.
Be careful not to scar the teeth of the gear.
6) Locate the 5 screws securing the Bottom Plate to the Middle Plate. Remove the 5 screws.
7) Running a Flat Head Screwdriver around the sides of the Twisting Head Assembly between the Middle
Plate and the Bottom Plate, separate the Plates. Gently lift the Bottom Plate until it can be removed.
Note:
Due to lubrication, the Needle Cam may stick to the underside of the Bottom Plate when it is
removed. Turn the Bottom Plate over and look at the underside, if the Needle Cam is stuck to the
Bottom Plate remove it and put it back onto the Main Shaft in the same direction as it came off. It is
very important that it is in the same direction. Make sure that the Needle Cam is seated properly
and secured by the keys. See Figure 15.
To replace the Bottom Plate:
1) Verify that the Needle Cam and all other parts are properly installed.
2) Slowly lower the Bottom Plate onto the Shaft. Due to holes that must line up with in the Bottom Plate and
the Middle Plate, some twisting of the Bottom Plate may be required. Once the holes are located push on
the Bottom Plate securely until it meets the Middle Plate.
3) Replace the 5 screws that were removed in Step 6 above. Make sure that the 2 countersunk screws go into
the holes at the front of the Twisting Head Assembly.
4) Slide the Main Shaft Gear onto the Main Shaft, making sure that the Set screw lines up with the Hole in the
Main Shaft.
5) Tighten the Set Screw securely.
6) Re-install the Twisting Head Main Assembly per the instructions in Section 6.
The following parts can be accessed by removing the Bottom Plate; the Needle Cam and the Needle
Arm, Needle Left, Needle Right, and the Movable Blade. It may also be necessary to remove the Bottom
Plate to lubricate using a medium weight machine grease the Needle Arm and the Needle Cam.
See Figure 14 and 15 on the next page.
