Operating techniques
Operating in uneven terrain or on slopes 51
Operating in uneven terrain or on
slopes
– Make sure that the angle of the gradient is not increased by an
obstacle.
– On when digging a trench in a sloping position start work at the
highest point (dozer blade positioned on the ground behind the
excavator for support). Empty the bucket facing the slope.
– Do not drive backwards downhill.
– Do not change the travel direction and do not travel transverse
when driving on a slope.
– If the machine starts to slip immediately lower the bucket to the
ground.
Digging a trench
When excavating a trench it is recommended to dig in layers, thus
to obtain a level trench bottom. Use a combination of bucket, dip-
per and boom motions to maintain the angle of the bucket while
digging.
1 Anchor the dozer blade into the ground behind the excavator.
2 Extend the excavating equipment and place the bucket verti-
cally with teeth on the ground.
3 Start digging by operating the bucket cylinder. Simultaneously
operate the bucket and the dipper arm cylinders once half of
the digging cycle has been reached.
NOTE! Do not dig the bucket too deep into the ground, since
this would block the digging action. However, should this oc-
cur, slightly raise the boom.
Avoid working jerkily.
Completely close the bucket when filled. Raise the boom and si-
multaneously start the swing motion, until the unloading position is
reached.
WARNING!
Make sure that the machine’s tipping limit is not exceeded
before starting work on uneven ground or on a slope.
