EXPLANATION OF COMPONENTS
Automatic lock function of lock lever
•
The lock lever automatic lock function assists the operator in judgment to reduce damage caused
by accident. This is not a device that can 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. Also, the lock lever automatic lock
function may not work in the following cases. Do not rely on it too much.
•
When the hydraulic oil temperature is low (When the hydraulic oil temperature caution lamp in-
dicates low temperature)
•
When the viscosity of the hydraulic oil used is higher than that of the genuine hydraulic oils
which Komatsu recommends
•
Before setting the lock lever to FREE position, make sure that all control levers and 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 prevents the work equip-
ment or machine from operating unexpectedly 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 it is 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 the control levers or attachment control switches are op-
erated 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.
For the genuine hydraulic oils which Komatsu recommends,
see "RECOMMENDED FUEL, COOLANT, AND LUBRICANT
(7-5)".
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.)
