Place the machine on a flat ground or in a vehicle box, carefully check for looseness, 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; if incorrect, swap the power phase sequence.
Connect the inlet and outlet pipes and tighten them. Note that the outlet pipe and port must be tightly connected to avoid being washed off by pressure.
After fixing the pipes, start the motor button. The oil pump works normally, and the oil after three-stage filtration is purified oil.
When switching oil tanks, act quickly to avoid dry running of the oil pump; if unable to stop in time, reconnect the inlet pipe and restart.

Features
Simple structure: composed of motor, filter pump and filter, easy to operate and maintain.
Multi-stage filtration: one-stage coarse filter and four-stage fine filter to achieve high oil cleanliness.
Portable design: mobile cart structure, suitable for on-site and bypass filtration.
Complete protection: thermal relay protection prevents motor overload damage.
Customizable precision: fine filter can be selected with different precisions according to user needs.
Stable operation: driven by a special gear pump with low noise and strong self-priming capacity.
Advantages
Simple operation: special gear pump drive with low noise, strong self-priming capacity and stable operation.
Pump protection: oil suction port coarse filter protects the oil pump and prolongs the service life of the main filter.
Motor protection: thermal relay protection prevents motor damage caused by overload.
Customizable precision: fine filter can be selected with different precisions (3, 5, 10, 20, 30μm) to meet purification requirements.
Convenient maintenance: quick-opening filter housing design, easy to replace filter elements.
Flexible application: portable cart structure, suitable for on-site purification and bypass filtration.
