Joystick Control
The speed and force of a hydraulic excavator's movements are controlled by the joystick. A small joystick stroke produces slow, gentle movements; a large stroke delivers fast, powerful actions. Mastering joystick stroke control — often called "driving feel" — is the most fundamental skill for any excavator operator.
Avoid jerking the joystick to its maximum position abruptly — this causes sudden acceleration and severe shaking, a common mistake among beginners. Instead, transition smoothly from a small stroke to a larger one, with a gentle buffer in between, so the excavator moves steadily and precisely.
Digging
Digging is the core operation of an excavator. A key technique is adjusting the bucket teeth angle to match the boom trajectory. Think of the bucket teeth as a knife slicing through vegetables — they should cut into the soil, not slam into it. Once inserted to the desired depth, curl the bucket and raise the boom in one smooth motion. That's a perfect digging cycle.
When digging along a soil edge with hard ground, use only two or three bucket teeth to score the soil first, then dig out the section as a whole. For loading or other high-efficiency operations, always fill the bucket completely before lifting.
After lifting the bucket, minimize all other simultaneous movements and focus entirely on the swing motion — this maximizes swing speed. When excavating while swinging, keep the bucket slightly tilted forward rather than horizontal; this prevents soil from spilling out the back due to inertia.
Trench Digging
Trench digging may look simple, but doing it well requires solid technique. Two requirements are essential: straight and smooth.
Straight — Excavate precisely along the designated route. On site, the trench line is usually marked with white lime. If no line exists, only a few reference points may be marked. Walk the tracks between these points first — the track marks can serve as your guide line, just avoid running over the markers themselves. Align the excavator's center and the middle bucket tooth with the line, and the trench will follow straight.
Smooth — The trench bottom should be even, and the slope controlled to specification. Since the operator often cannot see the trench bottom accurately from the cab, get out and check frequently, or ask a ground worker to measure with instruments.
In practice, summarizing these techniques and adapting them to different situations is what turns an operator from beginner to proficient — directly improving daily work efficiency.
