Those who operate excavators know that besides maintenance and upkeep, the main cost of daily work is burning oil. Do you feel a slight heartache every time you refuel the machine? Since refueling is unavoidable, efforts should be made to save fuel. Today, we will provide some fuel saving techniques for excavator operation.

Excavators should be positioned as high as possible during loading, and trucks should be parked at a height as consistent as possible with the working surface.
The reason is simple, it's like asking you to pass something up or stepping on a stool to pass something, which one is more effortless. Excavators are the same, the more labor-saving they are, the lower their fuel consumption will naturally be.

When the bucket cylinder and connecting rod, as well as the boom cylinder and boom, are all at a 90 ° angle, each cylinder exerts the maximum force to push the excavator.
Just like digging with your hands, only digging directly is the most effortless.

Excavation of natural ground, keep the floor angle of the bucket or soil loosening device at around 30 °, and retract the bucket rod. When the boom is close to vertical, the boom has the maximum force and can carry more load.
Is it easier to lift things with your arms bent or straight? Of course it's curved.

At the beginning of excavation, do not extend the boom to its maximum range of action. The best effect is achieved from around 80%.
When the maximum range of action of the boom is reached, the digging force of the boom is the smallest, making it difficult to excavate. This is something that beginners usually pay more attention to.
The appropriate rotation angle is 30 °~45 °. During excavator loading operations, the rotation angle of the excavator must not exceed 60 degrees. The smaller the angle, the faster the rotation, the higher the output, and naturally the lower the fuel consumption.
When conducting continuous excavation, the chassis is placed in the forward direction and can immediately move after the excavation is completed. If it is changed while walking, it will burn a lot of oil after starting.
When digging trenches, first excavate the sides of the trench, and then excavate the middle part. This way, digging in the middle can save a lot of trouble and effort.

Place the engine throttle in the economy position. Select the automatic idle function and let the engine idle during excavation.
The smaller the excavation depth, the more economical the excavation, and it is recommended to use segmented excavation as much as possible.
Divided into upper, middle, and lower layers of excavation, if one excavates from bottom to top, the first step is to increase the range of action, and secondly, the power of the excavator decreases due to the increase in range, reducing work efficiency, which requires a lot of oil.
As long as you can develop good operating habits and accumulate them over time, you can indeed save considerable fuel costs.
