• If there is a hard rock-bed during the ripping operation, ap-
ply the second ripping in the opposite direction to the first
ripping.
If you still cannot break the rock-bed, break it little by little
from its periphery.
• When ripping a hard rock-bed intensively, rip all over the
site first, and then rip intensively. The work efficiency is
higher in this way.
DIG UP LARGE BOULDER
If you encounter a large boulder which you cannot break easily and the shoes slip during ripping work, dig it up
according to the following procedure.
1.
Depress the decelerator pedal.
Decrease the engine speed to a degree that the shoes do
not slip.
2.
Operate the ripper control lever to tilt the ripper, and break
and dig up the boulder.
3.
If you cannot break and dig up the boulder by tilting opera-
tion, tilt back the shank while traveling forward a little, and
then dig up by tilting operation.
