3.36 Working with the excavator
Working with the standard bucket
The following section describes work operations with the machine equipped with the stan-
dard bucket.
The standard bucket is mainly used for digging earth, and for loosening, picking up, dig-
ging and loading loose or solid material.
Prohibited operation
Working with the swivel force
☞ Do not use the swivel force of the upper carriage to compact the ground or tear down
piles or walls.
☞ Do not allow the bucket teeth to penetrate into the ground as you rotate the upper car-
riage.
➥ Working this way damages the attachments.
Working with the drive force
☞ Do not allow the bucket to penetrate into the ground and do not excavate by using the
drive force of the machine.
➥ Working this way may damage the machine or the attachments.
Avoid impact during operation to avoid damage to the excavator bucket and
machine components.
☞ Do not suddenly drop the bucket to increase penetration, break material, or compact
material.
➥ Working this way can greatly reduce the machine's service life.
