WARNING
q
When not using the swing operation, e.g. when travelling, put the swing lock switch to the ON posi-
tion.
q
On slopes, even when the swing lock switch is at the ON position, the weight of the work equipment
may cause the upper structure to swing if the swing control lever is operated in the downhill direction,
so always carry out operations carefully.
This switch (4) is used to lock the upper structure so that it can-
not swing.
(a) ON position (actuated): The swing lock is always applied,
and the upper structure will not swing even if the swing is oper-
ated. In this condition, the swing lock lamp lights up.
(b) OFF position (cancelled): The swing lock is released, when
operating the swing control lever, allowing the upper structure
to swing.
