Komatsu D155AX-8E0, Operation & Maintenance Manual

Page: 254 / 420

To finish the ground to a flat surface after digging or piling soil,
put a full load of soil on the front face of the blade and operate
the blade up and down in small movements while traveling for-
ward.
When leveling track shoe traces or small windrows, set the
blade at “FLOAT” and drive the machine at low speed in re-
verse while pulling the blade on the ground surface.
At this time, hold the lever with your hand for at least 1 second
so that the lever is held in “FLOAT” state securely.
Avoid running over stones or rocks to protect the blade.
WORKS OF CUTTING INTO HARD OR FROZEN GROUND OR DITCH
For digging and ditch excavation of hard or frozen ground, tilt
the blade. Even hard ground can be dug effectively by a tilted
or angled blade.
WORKS OF FELLING TREES AND REMOVING STUMPS
NOTICE
Do not perform stump removal or other hard work by tilting the blade.
For trees with a diameter of 10 to 30 cm, raise the blade high
and push a few times to fell the tree.
Next, travel in reverse, and dig the corner of the blade into the
ground to cut and dig up the roots.
When doing this, never hit the tree at high speed or apply
shock to fell the tree.
PUSHING WORK
NOTICE
• When performing pushing operations, always install
the pusher plate.
• When approaching the objective machine, decrease
the travel speed with the decelerator pedal or fuel con-
trol dial and bring the plate in contact with the objec-
tive machine slowly.
After the plate comes in contact, increase the travel
speed gradually and push with full power.
