Scraping-down Operations are Prohibited.
Never use the front bucket of a bottom-dump bucket to scrap
down rocks or soil.
Digging Rocky Ground
Do not attempt to directly excavate hard rocky ground with the work equipment. It is better to excavate it after
breaking up by some other means. This will not only save the machine from damage but will make for better econ-
omy.
Phenomena that do not Indicate Failure
Note that the following phenomena are not failures:
q When starting or stopping the swing, noise will be emitted from the brake valve.
q When going down a steep slope at low speed, a noise will be emitted from the travel motor.
q The arm may sometimes stop when the bucket teeth
become more or less horizontal.
q The bottom dump of the bucket may sometimes stop at the
bottom horizontal position when the bottom dump control
lever changes from open to close.
