USING THE MACHINE AS A LOADER 125 RWA00470 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, raise the arms gradually and at the same time retract the bucket to the end of its stroke. 3 - Reverse the motion of the machine and dump the bucket on- to the truck. Reverse the motion of the machine and dump the bucket on the truck. After unloading the material on the truck, use the “return to dig” device of the loader hydraulic system to accel- erate the operations.
Once the device has been connected, it lowers the arm com- pletely and at the same time brings the bucket in perpendicu- lar 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 “3.3.5 MACHINE CONTROLS Pos. 4”.
