Operation
Working with the Excavator Arm
69 9821/6100-4 69
Notice: Do not use the side of the excavation to stop the bucket when slewing back into position for the
next dig. Similarly, do not use the side of the bucket to push soil into the excavation. Both these practices
will damage the machine.
It is possible when excavating, to use either full machine slew when discharging a loaded bucket, or if conditions
dictate, swinging the excavator end only to the required dumping area.
1. To start the dig, reach out with the boom and dipper and position the bucket.
2. Slowly crowd the bucket at the same time bring the dipper in. Make sure the bucket stays at the same angle
to the ground while it travels. If necessary, at the same time apply a downward pressure on the boom, to
increase the digging force on the bucket.
Figure 57.
3. When the bucket is full, crowd it fully and at the same time move the dipper out a small distance. This will
keep soil from building up under the machine.
Figure 58.
4. Slew the machine or swing the bucket to the dump area.
Figure 59.
5. Start dumping as the bucket approaches the pile. Do not waste time by dumping too far from the excavation.
Dump close to the start dig position.
