Air Compressor Pressure Switch Adjustment

Here is the step-by-step procedure, follow the following steps, and understand how it will work. So let’s know more about it.

Step 3: Check the status whether it’s half or full

The noise of the air compressor will let you know whether it is full or not. But you make sure that the tank must be full.

Step 4: Measure the PSI and check the compatibility of air tools with your compressor

The right time to measure the PSI is when the pressure is at its peak. This is the time when you should check the compatibility of your air tool.

If the PSI on your air tool is higher than that of your air compressor then the air tools cannot go with the air compressor. It needs to be replaced. But if the PI is smaller than the air compressor than your air tools are perfect for your air compressor and you can move on further.

Step 5: Hose the air conditioner and connect your tool

Once the compatibility is checked, connect your air tool with the hose. Now connect the air hose with the compressor. You will see a port where you can connect the air hose.  If you can’t find it then go through the manual then you will find it.

By turning the knob in the clockwise direction you will notice that the pressure will increase.

Note: Pull out the knob to unlock, if you support this feature.

Step 9: Select the correct pressure and lock the knob

If you want to bring the pressure down then you can turn the knob in an anti-clockwise direction. You will notice the pressure drop soon. Also make sure that you have a push in the knob to lock it.
