EXPLANATION OF COMPONENTS
The lock lever automatic lock function prevents the work equip-
ment or machine from operating unintendedly when the lock
lever is released while the work equipment control lever or trav-
el lever is operated. The lock lever is set in the same state as
when locked automatically.
When this function works, the operations of the work equip-
ment, swing, travel, and attachment are locked automatically
and the message shown in the figure is displayed.
While this function is in operation, the machine does not move
even if a control lever or the attachment control switch is oper-
ated while the lock lever is in FREE position (F).
To cancel the lock, return the lock lever to LOCK position (L),
check that each control lever and the attachment switch are in
neutral, and then release the lock lever again.

TRAVEL LEVER
•
If you perform operations with your foot on the pedal, the machine may suddenly start if you de-
press the pedal by mistake, and this may lead to serious personal injury or death. Be extremely
careful when using the pedal for travel and steering operations, and do not put your foot on the
pedal when it is not necessary.
•
When the track frame is facing the rear, the direction of operation of the steering lever is the oppo-
site to the direction of movement of the machine (forward/reverse, right/left turn).
When operating the travel lever, always check if the track frame is facing the front or the rear. (If the
sprocket is at the rear, the track frame is facing the front.)
The travel lever is used to change the direction of travel be-
tween forward and reverse. ( ) shows the pedal operation.
(a) FORWARD

(Depress the front side of pedal.)
(b) REVERSE
The lever is pulled back
(Depress the rear side of pedal.)
N (NEUTRAL)
The machine stops.
REMARK
