SECTION 3

Soil levelling. For filling and levelling the soil after
the excavation work, the bucket must be moved hor-
izontally forwards and backwards.
To level the soil, material has to be shoved or raked
with the bucket.
The levelling operation must be performed by
extending the dipper slowly, by raising the boom
slightly and then, when the dipper crosses the verti-
cal position, by lowering slowly the boom. Now
move the machine so that the bucket movement is
held horizontal.
For the soil levelling in the opposite direction, per-
form the above mentioned operation in reverse
order.
For the working operations described above, sev-
eral bucket movements can be combined. By corre-
sponding actuation of the boom control lever, it is
possible to cut a slope and to level it at the same
time.
