Loading Heaped And Level Material - Komatsu WB93S-5 F50003 Operation & Maintenance Manual

USING THE MACHINE AS A LOADER
3.12.2.1 LOADING HEAPED AND LEVEL
MATERIAL
The efficiency of the bucket depends on how the operator starts
loading; proceed as follows:
1 - Start moving and direct the bucket towards the heap base.
2 - While the upper material falls down filling the bucket, lift the
arm gradually and at the same time fold the bucket
completely.
3 - Reverse the motion of the machine and dump the bucket
onto the truck. After unloading the material on the truck, use
the "return-to-dig" device of the loader hydraulic system to
accelerate the operations (if such device is provided).
Once the device has been connected, it lowers the arm
completely and at the same time brings the bucket in
perpendicular position with respect to the ground. This is
particularly useful for the operator, since in this way the
machine is ready for the successive loading phase. For the
correct use of the "return-to-dig" device, see "3.3.6 pos. 4 -
FRONT LOADER CONTROL LEVER".
IMPORTANT
Start loading the truck from the cab side and, if the material
q
is sufficiently homogeneous, dump from the maximum
height in order to increase the compaction of the material
and its distribution on the loading platform.
