cylinder, don’t allow bucket cylinder to collide with ground or
bucket tamping when the bucket cylinder is fully extended
(bucket fully retracted).
Adjust the digging length and depth every time to ensure every
digging is fully loaded. In order to increase throughput, full load
should be the first important goal, and then the working rate.
Don’t try to extend arm fully and drop bucket, penetrating
ground with bucket teeth to dig up rocks. These will cause
serious damage of machine.
