Operation Method
Place the machine on flat ground or in a vehicle box, carefully check for loose parts, especially ensuring the connection between the motor and oil pump is tight and concentric.
Connect the power correctly, start the oil pump to check the rotation direction; reverse the phase sequence if incorrect.
Connect the inlet and outlet pipes and tighten them. Note that the outlet pipe and port must be secured to prevent being washed off by pressure.
After fixing the pipes, press the motor button to start operation. The oil after three-stage filtration is purified oil.
When switching between oil tanks, act quickly to avoid dry running of the oil pump. If unable to stop in time, reconnect the pipes and restart.

Equipment Advantages
simple operation: Driven by a special gear pump with low noise, strong self-priming capacity and stable operation.
pump protection: Suction port coarse filter protects the oil pump and extends the service life of the main filter.
motor protection: Adopts thermal relay protection to prevent motor damage caused by overload.
flexible precision selection: Fine filters can be selected with different precisions according to user needs to achieve the desired results.
