R928041210 UTERS replace of Rexroth filter element

Instructions for use

01. The hydraulic filter n the hydraulic system to filter out particles and rubber impurities in the system to ensure the clean the hydraulic system. When refueling, the hydraulic oil must be filtered, and the refueling tools should be clean and reliable. The filter at the filler port of the hydraulic oil tank cannot be removed in order to increase the fueling speed. Fueling personnel should use clean gloves and work clothes.

02. Ensure that the hydraulic oil is not used at high temperatures; the oil will quickly oxidize and deteriorate at high temperatures; the air filter on the hydraulic station should use a filter that can filter both particles and moisture; it is sold on the market;

03. The cleaning oil of the hydraulic system must use the same brand of hydraulic oil as the system used, and the oil temperature is between 45~80℃. Use a large flow to remove the impurities in the system as much as possible. The hydraulic system should be cleaned more than three times repeatedly, and all of it will be discharged out of the system when the oil is hot after each cleaning. After cleaning, clean the filter again, and add new oil after replacing the new filter pan>

Supplementary note: The filter ally a consumable product, and it needs to be replaced immediately after it is usually blocked. Pay attention to the system oil tank and pipebe flushed clean. When refueling, pass through a refueling device with a filter. Do not let the oil in the tank directly the air. Do not mix new and old oils. It is helpful to extend the service life of the filter span>

Maintenance items

01. Drain the original hydraulic oil before replacement, check the oil return filter filter t filter there are iron filings, copper filings or other impurities. If there are hydraulic component failures, clean the system after troubleshooting. .

02. When changing the hydraulic oil, all hydraulic oil filter oil filter ion filter lter replaced at the same time, otherwise it is equivalent to not changing.

03. Identify the hydraulic oil label. Different labels and different brands of hydraulic oil should not be mixed, and may react and deteriorate to produce flocs. It is recommended to use the specified oil for the excavator.

04. The oil suction filter nstalled before refueling. The nozzle covered by the oil suction filter leads to the main pump. The ingress of impurities will accelerate the wear of the main pump, and if it is heavy, the pump will be used.

05. Fill the oil to the standard position, there is usually an oil level gauge on the hydraulic oil tank, please check the level gauge. Pay attention to the parking method, generally all the cylinders are retracted, that is, the forearm and bucket are fully extended and landed.

06. After refueling, pay attention to the main pump to exhaust air, otherwise the whole vehicle will not move temporarily, the main pump will make abnormal noise (air sonic boom), and the main pump will be damaged by cavitation. The method of exhausting air is to directly loosen the pipe joint on the top of the main pump and fill it up directly.
