SECTION 3
WORKING STAGES
If possible, working operations should always be
carried out by pulling the dipper. When digging, use
the retracting forces of the dipper and work with
shallow cutting angles of the bucket.
Steep bucket angles during digging reduce the per-
formance.
Make smooth and regular movements with the
boom. Raising and lowering of the boom must
always be initiated slowly and smoothly. When the
boom is stopped abruptly, the machine is subjected
to heavy shock loads, this results in excessive wear
and damage.
Hold the teeth of the bucket in the direction of dig-
ging. This reduces the digging resistance and possi-
ble damage of the teeth.
