OPERATING METHOD FOR RIPPING WORK
BASIC OPERATING METHOD
(1) Lowering point to ground
(2) Penetrate to specified depth with point
(3) Ripping
(4) Start raising ripper
(5) Tilt back shank
(6) Start lowering ripper
LOCUS OF RIPPER SHANK
Perform the ripping operation according to the following procedure so that the ripper shank draws the above
locus.
1.
Tilt back the ripper.
2.
Lower the ripper point to the point to start ripping, and raise the rear part of the machine.
3.
Depress the decelerator pedal and decrease the engine speed.
4.
Set the gear speed to F1 and penetrate the ripper point at the specified place to the specified depth by rip-
per tilting operation.
5.
When the ripper point reaches the specified depth, increase the engine speed to high idle and drive the
machine forward.
6.
While traveling forward, tilt the shank and perform ripping.
If the oil is relieved when the shank is tilted, lower the shank mounting hole by 1 step to decrease the rip-
ping depth.
7.
After ripping is finished, pull out the shank from the rock-bed while traveling forward, and then drive the ma-
