First change to the manual operation. Then, after the operation lever that corresponds to the
error number is manually returned to the neutral position, change to the radio-control mode
and check that the error number disappears.
When the mode indicator lamp displays the normal number and when the error number does
not reappear after operation is made, the operation can be continued. If the operation lever
cannot be moved or if the error number does not disappear, then radio-control operation is
impossible. Change to the manual operation and then operate the crane.

“62”: Winching operation

[NOTICE]
! This is a measure to stow the crane in an emergency case. Do not make any crane operation.
Fastening the screw too tight may cause operation failures. Make sure to lightly tighten the screw.
1. The unloading solenoid of the radio-control valve
should be fastened so that the crane can be
manually stowed.
(1) Remove the cap nut.
(2) Loosen the lock nut and lightly tighten the
screw inside until it cannot be turned
any longer.
It is dangerous to make other operations when the operation
lever of the part that has a problem cannot be returned to the neutral
position, since this would cause the part that has a problem to move
at the same time. Do not make such operations.
