Komatsu D155AX-8E0, Operation & Maintenance Manual

Page: 113 / 420

This function is used for storing the ripper automatically when the machine travels in reverse after ripping opera-
tion.
• Since the ripper does not need to be controlled manually, the operator's work load is decreased.
• This function can be turned ON and OFF with the work equipment automation switch on the monitor switch
section.
• The ripper auto-return function does not operate when the machine travels in reverse after working with the
blade.
• The ripper auto-return function has the 3 modes of lift only/ lift and tilt independent operation/ lift and tilt
interlocked operation, which can be set on the "Mode Select" screen.
• Setting of the ripper auto-return function can be checked
by the ripper auto return pilot lamp (M) displayed on the
machine monitor.
(A): Lift only (blue)
(B): Lift and tilt independent operation (blue)
(C): Lift and tilt interlocked operation (green)
(D): Function OFF (background color of symbol)
• The ripper auto-return pilot lamp lights up in yellow while
the ripper auto-return is in operation.
• When the ripper auto-return is interrupted, the ripper auto-
return pilot lamp flashes.
Lift and tilt interlocked operation
• While the machine is traveling in reverse after the ripper
control lever is set in LIFT RAISE position (a), the ripper
rises to the stroke end automatically even if the ripper con-
trol lever is returned to NEUTRAL position (b).
After the ripper rises to the stroke end, it automatically tilts
back fully.
• When the ripper control lever is set to LIFT LOWER posi-
tion (c) or the tilt control switch is set to TILT IN position (A)
while the ripper auto-return function is in operation, the
manual operation is given priority and the ripper auto-re-
turn function is canceled.
