1、 Engine:
The engine oil and the engine oil filter are absolutely original parts, and they need to be replaced during the maintenance period.
The maintenance and maintenance of the excavator and the utilization of diesel oil are supplied to the regular gas station, even if the diesel oil of the regular gas station is not directly into the tank and is added before the sock first filter of the fuel filler cover). The diesel tank and at the bottom of the oil-water separator began draining the day before. Purchase ordinary diesel filter factory parts, and replace the diesel filter in the required maintenance cycle.
The air filter element is often inspected, and the external filter element is often blown out by compressed air from the inside to the outside. The air pressure should not be too high to prevent the filter from blowing. The internal filter cannot be cleaned. After 2 or 3 times of external filter cleaning, the internal filter is replaced with a new one.
Do not use idle work for a long time to save fuel and prevent carbon deposition.
2、 Hydraulic pressure:
The specified maintenance interval hydraulic oil is changed to return oil filter, pilot filter, filter and note that there is no adsorption of iron and copper scraps. The main body of the traveling device for the repair and maintenance of the Carter rotary excavator and the hydraulic excavator is provided with the device and transmission of the power of the upper tower. Repair excavator engine power source, the most convenient site to use diesel, can use electric motor.
When the crusher is used, the deterioration speed of hydraulic oil is accelerated and the replacement period is shortened.
Do not work without oil for a long time. Hitachi excavator is famous for its efficient and innovative maintenance. It also aims to ensure the efficient and safe operation of small-scale operation areas and is therefore particularly suitable for densely populated urban areas.
Replacing the sundries stacked in the tank, especially metal tools, may easily cause fire.
Do not replace the iron wire and copper wire fuse, and do not replace the unqualified fuse.
Dig for oil.
Pay attention to clean the dirt and sundries on the pin shaft and add lubricating grease.
During wading operation, when water overflows the rotating gear ring, pay attention to replacing the lubricating grease in the rotating gear ring.
Pay attention to rust prevention of cylinder rod.
When the excavator is maintained for a long time, the exposed metal will be coated and rusted. Komatsu excavator repair and wheel loader maintenance performance. In order to maximize the work efficiency of customers, Komatsu has maintained consistent excellent quality and high reliability, reflecting the perfect unique technology. Pay attention to environmental protection and people-oriented to make driving more comfortable and easy to maintain. This is a small loose wheel loader, focusing on the future standard design.
5、 Structure:
The daily movement pin bolts have been reviewed for falling off, missing, and ensuring timely.
Check the structure daily for cracks and deformation.
When repairing the excavator in the park, pay attention to the surrounding environment, park it on a solid and stable hard ground, and do not park it on the river, cliff side or under the mountain to prevent the danger of going out.
During parking, the bucket cylinder is fully recovered and the bucket falls on the ground to prevent the cylinder from being hit.
