Explanation of maintenance steps for wheeled excavators

1. The spatial position of the wheel excavator dashboard.
To ensure high efficiency and reduce fatigue, the spatial position of the dashboard should allow the wheeled excavator operator to see all instruments without moving his head and eyes, and not moving his body position. This reduces operator fatigue and makes operation simpler, safer, and more effective.
2. Instrument layout on the dashboard of a wheeled excavator.

According to the assumed motion law, the dashboard of a wheeled excavator should be rectangular with long sides in the left and right directions. The arrangement order of the instruments on the dashboard should comply with their reading order. This is easy to operate and allows for a quick and accurate understanding of the operation of various parts of the wheeled excavator. The more interconnected the instruments are, the closer their arrangement is to the quality of small wheeled excavators. The arrangement of instruments should also take into account the logical connection between them.
3. Effective identification range of the dashboard surface of wheeled excavators
Experiments have shown that when the observation distance is 800mm, if the eyeball does not move, a 20 degree field of view is a good reading range, and the correct reading time is about 1 second. When the horizontal field of view exceeds 24 degrees, the correct reading time begins to increase sharply, so 24 degrees is the limit of a good reading range.
Summary:
The dashboard of a wheel excavator is easily overlooked by buyers and is actually very important for wheel excavator drivers. A good dashboard design can reduce the burden on operators, allowing them to easily obtain the status of wheeled excavators and direct their work. When we purchase wheeled excavators, our consistent pursuit of cab space is not very reasonable. It is important to consider whether the overall cab layout is truly reasonable, depending on your body, and choose a wheeled excavator that allows you to easily observe the dashboard.
Abstract: In order to better utilize wheeled excavators and prevent various malfunctions, more attention should be paid to the use and maintenance of wheeled excavators in daily use. Wheeled excavators typically perform Level 1 maintenance, Level 2 maintenance, Level 3 maintenance, and Level 4 maintenance warranty systems for major repairs.
Daily maintenance and inspection of lubricants, coolant, and battery levels, and adding them if necessary; Check for oil, water, and electrical leakage, check the fastening of the main bolts in various parts, and timely loosen and tighten them; Check the tightness of the triangular belt, use thumb pressure (approximately 6 kgf) to place the belt in the middle, with a droop of 5-6 mm, and adjust or replace it as necessary; Check instruments, work lights, signal lights, and switches; Check or adjust the tension of the track, small wheeled excavator, with a droop of 25-40mm; Whether the operational performance of each lever is good; Check the dust indicator and clean or replace the air filter element if necessary; Check if the bucket teeth are loose and have residual defects; Check if the bucket teeth are severely worn, replace or repair them (depending on the situation); Add lubricating grease at the lubrication point of the working device; Discharge water and sediment from the oil-water separator; Check the electrical wiring for open circuits, short circuits, looseness, and other phenomena.
