1. After the oil filter works for a period of time, some impurities will remain in the fine filter. At this time, the amount of oil intake will be reduced or the oil will not enter. It can also be reflected by the pressure gauge, which can be used in the vacuum separator. The oil is backwashed.
2. Connect the single pump oil inlet to the oil pipe and extend it into the oil pipe for operation; first adjust the valve; open the backwash valve and single water pumping valve in the flow chart; close the water diversion inlet valve and pipeline valve in the flow chart .
The oil flow path is formed: oil in the vacuum separator - oil pump - fine filter - engine oil
3. Connect the oil drain at the bottom of the fine filter to the oil pipe and open the oil drain valve.
4. Use the pulse start oil pump (that is, intermittently turn on and off the oil pump), you can flush the fine filter.
5. After precipitation, the oil that can be backwashed with a fine filter is full of oil. After extraction and reuse, the residue underneath can be removed.
