Adjust the gas volume through the gas volume adjustment nut (indicated). Connect the power supply of the motor and set the motor indicator light to the on position. The motor starts to work, driving current to generate air pressure. Turn off the power supply, put the indicator light in the off-parallel state, and the motor will stop working. The principle of the machine is that the motor rotates at high speed to generate air pressure, which is then connected to the spray gun through a hose to deliver the air pressure to the spray gun for operation. During operation, the motor is cooled by a fan, so the temperature may be a bit high (about 45 degrees), but once it reaches a certain temperature, the machine will no longer rise. In addition, after removing the spray gun, it can also be used as a hair dryer (such as for dust removal on a computer)!
