(l)Immerse the suction strainer in water.

(2)Adjust the high pressure wheel of the pressure regulating valve to the lower pressure position counterclockwise, and then turn the pressure regulating handle clockwise to the pressure relief position.

(3)Start the engine and run at low speed for 10~15 minutes. If water is sprayed and there is no abnormal sound, gradually increase the speed to the rated speed. Then turn the pressure regulating handle counterclockwise to the pressurizing position and gradually tighten the pressure regulating wheel clockwise to increase the pressure, so that the pressure indicator indicates the required working pressure.

(4)When adjusting pressure, the value of pressure indicator shall be adjusted from low to high, and accurate pressure can be indicated by repeatedly pulling the pressure regulating handle on the pressure regulating valve several times.

(5)Try spraying with clean water. Observe whether there is leakage at each joint, whether the spray condition is good, and whether the mixer has suction.

(6)Blenders are only used with remote spray guns. Commissioning shall be carried out before use. Only when the flow rate of liquid pump is normal and there is suction force at the suction filter screen can the suction filter screen be put into the mother liquor bucket diluted in advance to start operation.
