When the oil filter unit is started, the oil pump can only work normally after confirming the direction of rotation of the oil pump.

✦ After using for a period of time, the noise of the oil pump increases due to the clogging of the coarse filter element, so the coarse filter element should be cleaned in time.

✦ After the fine filter element has been used for a period of time, when the pressure reaches 0.6Mpa due to the clogging of pollutants, it should be replaced in time.

✦ The oil filter runs normally, but no oil comes out of the oil outlet. Check whether the oil pump is turning correctly, whether the seal between the oil tank and the pump suction is reliable, and whether the oil suction is away from the oil surface or the oil has been sucked out.

✦ When the flow rate of the oil filter decreases, check whether the coarse and fine filter elements are seriously blocked, whether the shaft seal of the oil pump is worn or blown out or sucked in air due to reverse rotation.
