• The working mode becomes the manual mode for the
slope
surface of angle (G) is 70 ° and above when arm
OUT (J) is operated.
(The working mode becomes the auto stop control when
bucket operation or boom LOWER is operated.)
• The operation differs depending on the amount of digging
if the bucket digs in the design data (A).
(B) Less than 500 mm {1 ft 8 in}: Machine operates to ex-
tinguish the digging in amount with the auto grade assist.
(C) 500 mm {1 ft 8 in} and above, 700 mm {2 ft 4 in} less
than: The auto stop control operates.
(D) 700 mm {2 ft 4 in} and above: It changes to manual mode.
At finishing
• (E): Operation can be performed by the arm control lever
only.
• (F): By operating arm control lever with boom LOWER
control lever, you can move the bucket edge along to the
design data for all working area.
Auto stop control (in boom LOWER and bucket operation)
• When boom LOWER or bucket is operated, this automati-
cally stops the work equipment to prevent the bucket from
digging in the design data (A).
This controls not only the bucket edge but also the outline
of the bucket not to dig deeper than the design data. (mini-
mum distance control)
• The operation differs depending on the amount of digging
if the bucket digs in the design data (A).
Less than 700 mm {2 ft 4 in}: The auto stop control oper-
ates.
700 mm {2 ft 4 in} and above: It changes to manual mode.
Manual mode
The machine operates as same as operator's control.
In
manual mode, even if the blade edge exceeds the design data, automatic control of the work equipment is
not performed. Be careful not to dig in too much.
SEMI-AUTO MODE SETTINGS
The following is the procedure for shifting the semi-auto mode and manual mode.
