CAB LAMP SWITCH
This lights up the cab lamp.
ON position: Lights up
The cab lamp can be turned on even when the starting switch is
at the OFF position, so be careful not to leave it on by mistake.
PUMP CONTROL OVERRIDE SWITCH

(1) When abnormal: When the monitor display shows E02 (EPC
valve system error), it is possible to carry out operation when this
switch is moved up. The pump control override switch is designed
to allow operations to be carried out for a short period when there
is an abnormality in the pump control system (EPC valve system
error). The abnormality must be repaired immediately.
SWING LOCK OVERRIDE SWITCH
When normal: Switch (12) is down
(1) When abnormal: When the monitor display shows E03 (swing
brake system error), the brake is cancelled and it becomes possi-
ble to swing the upper structure when this switch is moved up, so
normal operations can be carried out. However, the swing brake
remains cancelled.
