[3.2] Tension calibration / zero adjustmentLower let-off (ground let-off)
(1) Read the scale 1 of the torsion back and record it.
(2) Rotate the lower beam forward until the dropper
lowers to the end.
(3) Loosen the bolt 2.
(4) Turn the worm 4 and release the distortion of the
torsion bar 6.
(5) Calibrate the tension on the function panel.
See steps (2) through (4) of tension calibration /
zero adjustment of ground let-off for tension
calibration.)
(6) Turn the worm 4 until the scale 1 reaches the
previous level.
(7) Tighten the bolt 2.
(8) Measure the warp beam diameter upon operation
start and input it on the [Map]-[Letoff] setting
screen.
(9) Start tension restoration.
Touching the tension restoration switch 9 starts
the tension restoration.
