How long has the machine oil core been used? If the time is not long, correct the two values â€‹â€‹of the alarm points of the oil core (only apply the palliatives and then use it at the top of the roof). If the oil is up to the time, it will be replaced. The oil pressure difference alarm indicates that the oil content is relatively dirty and blocked; if the oil content is too high, the pressure values â€‹â€‹of P1 and P2 will differ too much, which is not conducive to the stable use of the machine.
