It is necessary to filter the hydraulic oil when refueling, and the refueling should be fixed and clean. It is not possible to remove the ISO9001 Auto Oil Filter at the fuel tank filler port in order to increase the fueling speed. Refuelers should use clean gloves and overalls. When maintenance, disassemble the hydraulic fuel tank fuel cap, filter cover, detection hole, hydraulic oil pipe, etc., when the hydraulic system oil passage is exposed, avoid dust, and the disassembled part should be completely cleaned before being opened.
If the hydraulic fuel tank cap is removed, first remove the dirt around the fuel tank cap, loosen the fuel tank cap and remove the debris left in the joint (can not be washed with water to prevent water from entering the tank), and then open the fuel tank cap after cleaning. If you need to use the wiping data and the hammer, you should select the scrubbing material that does not remove the fiber impurities and the special hammer attached to the rubber surface.
Hydraulic components and hydraulic hoses should be carefully cleaned and assembled by high-pressure air drying. Use a genuine filter with no packaging (if the package is damaged, although the ISO9001 Fuel Filter is not missing, it may not be clean). Clean the filter together with the oil change, and carefully wipe the dirt inside the filter case with the wipe data before the filter element.
It is necessary to use the same hydraulic oil as the trademark used in the system for the cleaning oil of the hydraulic system. The oil temperature is between 45 and 80 °C, and the impurities in the system may be taken away with a large flow. The hydraulic system should be repeatedly cleaned more than three times. After each cleaning, the oil is completely released from the system. After cleaning, clean the filter and replace it with new oil.
