In general, solid materials invasion routes are: hydraulic oil is not clean; refueling tools are unclean; refueling and maintenance, maintenance care; hydraulic components desquamation. Solid impurities can be prevented from invading the system from the following aspects:
 
(1) The hydraulic oil must be filtered when refueling, and the refueling tool should be clean and reliable. It is not possible to remove the filter at the fuel tank filler port in order to increase the fueling speed. Refuelers should use clean gloves and overalls.
 
(2) Disassemble the hydraulic fuel tank cap, filter cover, detection hole, hydraulic oil pipe, etc. during maintenance. When the hydraulic system oil passage is exposed, avoid dust. The disassembled parts must be thoroughly cleaned before opening. If the hydraulic fuel tank cap is removed, first remove the dirt around the fuel tank cap, loosen the fuel tank cap and remove any debris left in the joint (can not be washed with water to prevent water from seeping into the tank), and confirm that the fuel tank cap can be opened after cleaning. If you need to use the wiping material and the hammer, you should choose a wiping material that does not remove fiber impurities and a special hammer that is attached to the rubber. Hydraulic components and hydraulic hoses should be carefully cleaned and assembled by high-pressure air drying. Use a well-packaged genuine filter (if the package is damaged, although the filter is intact, it may not be clean). Clean the filter at the same time as the oil change. Before installing the filter element, apply the wiping material to carefully remove the dirt inside the filter case.
 
(3) The cleaning oil of the hydraulic system must use the same hydraulic oil as the system. The oil temperature is between 45 and 80 °C. Use large flow to remove impurities from the system as much as possible. The hydraulic system should be cleaned more than three times. After each cleaning, the oil is completely discharged from the system. Clean the filter after cleaning, replace the new filter and add new oil.
