The preventive maintenance of the Hydraulic hose fittings involves many steps. It is warned that the maintenance or repair procedures should be done after disconnecting the pump from the power supply. The following are some things related with the preventive maintenance of the Hydraulic hose fittings. First of all, you should check the hydraulic fluid level. Proper oil level is 1/2 from the top of the fill hole when all wrenches are retracted. You must check the oil level in the reservoir regularly. Then you should drain, flush, and refill the reservoir with high-grade hydraulic oil after a certain period of use. Secondly, the cleaning maintenance is a crucial procedure for the preventive maintenance. Under this step, you should seal all unused couplers with thread protectors, and keep all hose connections free of dirt and grime and the pump's outer surface as free from dirt as possible. Besides, the equipment connected to the pump must be kept clean. Thirdly, you should drain and flush the reservoir. Before the pump interior is removed from the reservoir, you should clean the pump exterior. There are some things to follow. Remove the ten screws fastening the motor and pump assembly to the reservoir. You should make sure that you do not damage the gasket or bump the filter or pressure regulating valves when lifting the pump and motor off the reservoir. Clean the inside of the reservoir and fill with suitable flushing oil. Place the pump and motor assembly back onto the reservoir, and secure with two machine screws assembled on opposite corners of the housing. After then, you should run the pump for several minutes. Then disconnect the motor and pump assembly, and drain and clean the inside of the reservoir. At last, you should fill the reservoir with Hydraulic hose fittings. Place the pump and motor assembly on the reservoir, and thread the ten screws. In addition to the above mentioned steps, the oil should be added to the reservoir. Before doing this, wrench must be fully retracted and the power supply should be disconnected. You should clean the entire area around the filler plug before removing the filler plug, and use a clean funnel with filter when adding oil.
