Control Lever Auto-Lock - Hitachi ZAXIS 135US-6 class Operator's Manual

Control Lever Auto-Lock

This function keeps the machine from operating to prevent it
from moving contrary to the intention of the operator, in cases
like inadvertently unlocking pilot control shut-off lever (1)
when a control lever is engaged, such as by snagging a piece
of clothing.

WARNING:
 The control lever auto-lock function is designed to
inhibit unintentional operation of the machine and
does not stop the machine in every situation.
 When moving the machine, make sure all the control
levers are in neutral and then unlock pilot control
shut-off lever (1).
When this function is activated, the front, swing, travel and
attachment controls are automatically locked, icon (2) on the
monitor lights as illustrated and the buzzer sounds.
Once this function is activated, the machine cannot be moved,
even if a control lever is operated with pilot control shut-off
lever (1) still in the UNLOCK position.
To resume operation of the machine, return pilot control shut-
off lever (1) to its LOCK position, make sure control levers are
in neutral and then put the pilot control shut-off lever in its
UNLOCK position.

WARNING:
 The control lever auto-lock function does not
guarantee a full stop of the machine; in some
circumstances, the vehicle may move somewhat
before stopping after the function is activated.
 The time it takes to stop varies with hydraulic oil
temperature. The colder the oil, the longer it takes to
stop, so warm up the machine fully when it is cold.
 This function does not operate below a certain
temperature when the hydraulic oil is cold. Icon (2)
flashes on the monitor in conditions in which this
function will not operate.
 When a pilot hose is disconnected, this function
may not operate normally as system response
deteriorates due to the effect of the air. Warm the
machine fully after connecting hoses and air bleed
the pilot circuit. Refer to "Bleeding Air from the
Hydraulic System" on page 7-70 for information on
this procedure.
