When unloading a small excavator, it should be carried out after the bicycle stops. When unloading does not collide with any part of the dump truck, the height of the bucket should be lowered so that the bucket can pass through the top of the truck cab of the dump truck. When a small excavator encounters wires, intersections, bridges and culverts, it needs to be passed by professionals, and the distance between it and high-voltage wires should reach more than 5m. When working on a small excavator, it is forbidden to maintain it during this period, let alone adjust the engine, hydraulic system and electronic control system at will, create a reasonable working face, and do not dig holes at will. When the small excavator is running, its boom should be parallel to the running mechanism, the turntable should be locked, the bucket should be about one meter away from the ground, and it should be driven by downshifting when going downhill.
 

       When the mini excavator is swinging, the reverse handle cannot be operated in the opposite reverse direction. The walking path of small excavators should keep a certain distance from slopes, ditches and foundation pits to ensure safe passage. When passing through soft areas, low-speed uniform passage should be used, and wood and stone can be used as auxiliary materials if necessary. It is forbidden to crush the solid in the barrel. If encountering large stones or hard objects, it should be cleaned up in time. It is forbidden to dig rocks above Grade 5. It is forbidden to extend the oil cylinder completely through the bucket to lift the small excavator. When the bucket does not leave the ground, the small excavator cannot walk or rotate horizontally. It is forbidden to install a small excavator at the same time as the upper and lower excavation sections. When it moves on the working plane, the ground should be flat and obstacles in the passage should be removed.
 

       It is forbidden to use small excavators to drag objects laterally, and it is also forbidden to use impact method to excavate. Stable and reliable: The performance of the whole machine is more stable and reliable by adopting structural parts with enhanced design and large multistage air and fuel filtration systems. Energy saving: The special Kubota National Third Emission Engine, advanced SLSS hydraulic system and optimized power control mode improve the efficiency of the whole machine and reduce the fuel consumption. Adaptability: Tailless zero rotation design is adopted to ensure that the tail is always within the width range of getting off the train during the rotation process, which is especially suitable for operation in narrow places and has stronger site adaptability. Convenient maintenance: accessible butter filler, open cover design and detachable radiator filter screen make maintenance work such as lubrication, filter element replacement and radiator cleaning more convenient.
