OPERATION
Automatic lock function of lock lever
• The lock lever automatic lock function assists the operator in judgment to reduce damage caused
by accident. It does not stop the work equipment or machine in all situations.
• Even if the lock lever automatic lock function works, the work equipment or machine may not stop
immediately or may stop after moving by a certain distance.
The lock lever automatic lock function may not work in the following cases. Accordingly, do not rely
on it too much.
• When the hydraulic oil temperature is low
• When the viscosity of the hydraulic oil used is higher than that of the genuine hydraulic oils
which Komatsu recommends
• When the system has a problem
• Before setting the lock lever to FREE position, make sure that all control levers and control pedals
are set to NEUTRAL position.
If any of them is out of NEUTRAL position, the work equipment or machine may move suddenly and
cause a serious personal injury or death.
The lock lever automatic lock function automatically sets the lock lever in the locked state to prevent the work
equipment or machine from operating continuously when the lock lever is set to FREE position while the work
equipment control lever or travel lever is operated.
When the lock lever automatic lock function works, the operations of the work equipment, swing, travel, and at-
tachment are locked automatically. Even if any of control lever, control pedal, or attachment control pedal is op-
erated while the lock lever is in FREE position, the machine does not move.
While the lock lever automatic lock function is being actuated,
the display pops up, and the guidance icon on the right bottom
lights up in red.
If you press the function switch "F4", the screen changes to
"Lock Lever Auto Locked" screen and you can check the state.
If you press function switch "F3" on "Lock Lever Auto Locked"
screen, the screen returns to the pop-up display screen of it.
