OPERATION
DIGGING UP BOULDERS
During the ripping operation, if boulders are found which are difficult to break and shoe slippage occurs, dig up the
boulder as follows.
1. Depress the decelerator pedal and lower the engine speed to
a point where there is no shoe slippage.
2. Operate the ripper lever to TILT position and perform ripping
and digging.
3. If there are boulders which are impossible to break or dig up
with the tilt operation, move forward slightly and tilt the shank
back, then operate the tilt again and dig up the boulder.
4. Even when the operation in step 3 is repeated, if it is impossible
to break or dig up the boulder, drive back approximately 10 cm,
raise the shank, avoid the rock or boulder that cannot be
ripped, then drive forward and start ripping again.
