Checking / Setting Twine Bar to the Channel Slot
Fig. 185
Prerequisite:
– The machine is disconnected from the tractor.
– The flywheel brake is applied.
– The knotter gear is in idle position; refer to chapter Operation “Finishing Knotter Process
Manually”.
Checking the twine bar to the channel slot
• Pull the cotter pin and swing up the knotter, repeat the process for all knotters.
• Press the twine bar (1) manually to the channel slot (b).
• Measure dimension “a”, measured between twine bar tip and channel slot.
If dimension “a” is 0 - 5 mm, the twine bar is correctly set.
If dimension “a” is not 0 - 5 mm, the twine bar must be set.
Setting twine bar
To do this:
• Unscrew counter nut (2) and screw (4) of the joint bearing.
• Turn joint head (3) until dimension “a” is 0 - 5 mm.
• Tighten counter nut (2) and screw (4).
Repeat this process for all twine bars.
Check that the twine bar moves easily.
• Release the twine bar shaft, refer to chapter Settings “Tensioning / Releasing Twine Bar
Shaft”.
• Rotate the twine bar back and forth manually.
The twine bar is correctly set if it is easy to rotate the twine bar back and forth.
If it is hard to rotate the twine bar back and forth, there are several causes:
1. The control linkage is crooked, replace the control linkage.
2. The joint bearing is rusted, replace the joint bearing.
3. The axial play in the twine bar shaft is too low, remove the shim ring.
Remedy cause 1 to 3 and check or set the twine bar again, refer to chapter Settings “Checking /
Setting the Twine Bar to the Lower Needle”.
• Swivel the knotter down and secure with cotter pin. Repeat this process for all knotters.
Repeat this process for all twine bars.
• Tighten twine bar shaft, refer to chapter Settings “Tightening / Releasing Twine Bar Shaft”.
