Trenching operations

Extend the arm and boom and insert the bucket teeth into the soil surface.
Use the boom cylinder to dig. During the digging process, adjust the cutting and
loading angle of the bucket at the right time, or switch to digging with the bucket
cylinder. When digging, do not insert the bucket teeth too deep into the soil to avoid
overloading the hydraulic system. If soil resist stops the bucket, lift the arm
appropriately and continue digging. When the bucket is full, lift the arm and boom to
raise the bucket above the ground and turn the platform to the proper position to
unload.
