Operation
Excavator work position
Proceed as follows:
☞ Place stabilizer blade A on the side you want to dig
Bucket position when digging
☞ Move the bucket as shown in A.
➥ Move the flat side of the bucket parallel to the ground.
Position B causes the bucket to penetrate into the ground. Work slows down, and the
engine and the hydraulic pump are subject to overload if this position is used over a
longer period of time!
Position C causes the bucket to be forced upward and not to be filled completely.
☞ Excavate as follows:
• Penetrate into the ground with bucket D
• Lower the stick and at the same time align bucket E until
• reaching the required digging depth and
• the flat side of the bucket is parallel to ground
☞ Pull bucket E parallel to the ground toward the excavator;
if possible, at the same time:
• Move the stick toward the excavator
• Lower the boom
☞ With a sufficiently full bucket E:
• Keep on moving the stick toward the excavator and at the same time
• Tilt in stick F
Excavating trenches
• Excavating trenches is more efficient
☞ by using a suitable bucket for this work and positioning the tracks parallel to the limit
line of the trench.
☞ In case of large trenches, first excavate the side sections and then the center section.
