MACHINE OPERATIONS AND CONTROLS
When the blade automatic control is turned on, "AUTO" is
displayed on the control box screen.
2.
Set the joystick (steering, directional and gear shift lever)
to FORWARD position (F).
3.
Perform LOWER trigger operation.
Perform this when the blade edge is higher than the de-
sign surface and height of the ground where the track con-
tacts. In this case, the blade automatic control starts only
after LOWER trigger operation.
1)
Move the blade control lever to LOWER direction (C)
once and return it to NEUTRAL position (B).
The blade automatically lowers to the design surface
or height of the ground where the track contacts.
REMARK
•
Operator does not need to keep the lever at
LOWER position until the blade reaches to the
design surface.
•
While the machine is traveling or stopped, the
blade automatically lowers with LOWER trigger
operation.
Move the blade control lever to RAISE direction
(A) to cancel the blade automatic control.
•
If LOWER trigger operation is performed quickly,
the blade control lever may vibrate and may be
set in RAISE direction (A) and LOWER direction
(C) repetitively, and the work equipment may
hunt.
If the blade control lever vibrates, hold it with your
hand to prevent vibration.
4.
