OPERATION
BANK CUTTING POSTURE (RIGHT SIDE)
Lower the blade to the ground before removing the bank control lock pin. Do not remove it at any other position. There is danger
that it will rotate and the blade will fall.
NOTICE
When shifting to the bank cut posture, be careful not to let the blade hit any other part of the machine.
If the bank pin passes over the hole in the lifter guide, do not rotate the lifter any further. There is danger that the frame and bank
pin case will come into contact and that the bank pin case will be broken.
1. Extend the blade and drawbar fully to the right, rotate the circle
and set the end of the blade at the side of the front right wheel,
then lower the blade so that it is lightly in contact with the
ground.
2. Push the bank control lock pin switch and remove lock pin (1).
If lock pin (1) is held by lifter (2) and will not come out, operate
the blade lift cylinder to make it possible to remove the pin.
3. Check that indicator pin (3) at the rear of the lock pin has come
out fully and that the lock pin has been removed, then extend
the right blade lift cylinder and retract the left blade lift cylinder
to rotate lifter (2) counterclockwise.
Operate lifter (2) to the desired counter mark (A), then lock with
lock pin (1).
Check that the protrusion of indicator pin (3) has been removed
and that the lock pin is completely locked.
NOTICE
If the lock pin switch is kept pushed in the pin lock direction while the lifter
is being rotated, there is danger that the bushing or lifter ring will be
damaged. Rotate the lifter to the specified counter mark, then lock the lock
pin.
