Its main purpose is generating power for a long time by what the other component can operate itself. An air compressor draws the power from the engine, and a few have electric motors to do that job. It also requires electricity to run itself; often, we refer to that source of electricity as an electric wall outlet. However, in a few portable compressors, batteries are used to supply the required power.


This is the kind of the heart of this air compressor because its main purpose is to use the powers of the engine & draw the air & compress it.

How to turn off air compressor

Step 1

You have to open the tank first to drain all the things. You will find this valve in the under of the tank. You have to twist the valve a bit, mostly clockwise. This will create a pressure that will blow out all the moisture. This part is done, now put the valve in the previous position & stop twisting when you see no sign of airflow.

  • You can use pliers to twist the valve.
  • You should clear the tank after every use that will keep it maintained.

Step 2

Now it’s the step of turning off. You will have to keep the hose in its place until it is turned off. You have to twist the pressure regulator to turn off the compressor & always focus on the regulator knob because you will have to twist it to turn off the air supply to the hose. Now it’s the turn to turning off the compressor and waiting for the moment when the pressure will leave the system. You can pull off the relief valve to do the draining process fast.

Step 3

Now you have to remove the hose. After that, you can store your air compressor at a suitable place. You may unplug all the wires related to the air compressor.

Step 4

You have to replace the oil every year if your compressor is oil-filled. You know that the essential maintenance for an oil filling machine is clearing the oil up. You do it with various tools. However, the socket wrench can be the best option, in my opinion. Always use funnels while entering new oil in the machine. You can follow the manual for the process of changing oil.
