How to refuel the manual hydraulic truck
There is a hydraulic cylinder on the manual hydraulic carrier. The hydraulic cylinder is close to the upper end. There is a threaded bulkhead. When the bulkhead is unscrewed and the oil filling hole is seen, the manual hydraulic carrier can be filled with oil. The hydraulic oil in the hydraulic system plays the role of pressure transmission, lubrication, cooling and sealing. The improper selection of hydraulic oil is the main reason for the early failure and durability decline of the hydraulic system.
Under special circumstances, if it is necessary to use substitute oil, its performance shall be the same as that of the original brand. Hydraulic oil of different brands shall not be mixed to prevent chemical reaction and performance change of hydraulic oil. The dark brown, milky white and odorous hydraulic oil is deteriorated oil and cannot be used. The hydraulic oil must be filtered and filled, and the refueling tools shall be cleaned in time.
