Glassfiber Hydraulic Oil Filter are a crucial element of any system using hydraulic power and are designed to filter oils, water or other liquids, within a hydraulic installation application. Hydraulic systems have an increased risk of contamination due to wear of components, ingression from seals or low quality liquid. Proper filtration is necessary to keep the system clean and prevent the hydraulic installation from increased wearing.

2. When changing hydraulic oil, all hydraulic oil filter elements (return oil filter, oil suction filter, pilot filter) must be replaced at the same time, otherwise it is equivalent to no change.
3, Identify the hydraulic oil label, different grades, different brands of hydraulic oil are not mixed, may react to deterioration and produce flocs, it is recommended to use the excavator to specify oil.
4. Before the refueling, the oil-absorbing filter element must be installed first. The nozzle of the oil-absorbing filter core is directly connected to the main pump. When the impurities are light, the main pump is accelerated and the pump is pumped.
5, Refueling to the standard position, the oil tank generally has an oil level gauge, look at the liquid level gauge. Pay attention to the parking mode. Generally, all the cylinders are fully retracted, that is, the arm and bucket are fully extended and landed.
6, After adding the oil, pay attention to the main pump to discharge air, otherwise the light will temporarily no action, the main pump is abnormal (air blast), and the air pocket damages the main pump. The air exhaust method is to loosen the pipe joint directly on the top of the main pump and fill it up directly.
