Campbell Hausfeld has 66 air compressors in the market. And it doesn’t even include the inflators. These compressors are of ten types. But most of them have the same operational process.

The process written in this article is suitable for almost all compressors. You might have to do one or two steps more or less than what we have described. But that is also mentioned in the article.

You will also find all the necessary safety and maintenance procedures. I request you read the whole article to have a complete idea.

Guidelines on How to Use Campbell Hausfeld Air Compressor

Although there are minor differences in the process, it is pretty much the same as other compressors of the same kind. But setting the desired pressure in this compressor is very easy.

But there is more to the usage of the Campbell Hausfeld air compressor than just setting the pressure. We have divided the process into sections and given proper steps and instructions for each of them.

Not following the steps can cause problems like a reduced service life, inefficiency in operation, and adverse pressure on compressor parts.

So, I urge you to read every word here and follow the steps correctly.

Breaking in pump parts

The compressor needs a breaking period of thirty minutes before the operation for proper seating of the piston rings. This is how you are gonna do it-

  1. Remove the breather to put oil in the lubrication oil tank. It should always be full to the proper oil level before the operation. But don’t overfill.
  2. Release the tank drain valve to let out any water and vapor.
  3. Now, turn the pressure switch knob clockwise to its maximum position.
  4. Turn the pressure switch level (the on/off lever of the compressor) to the off position.
  5. Plugin power cord.
  6. Turn the pressure switch level back to the auto position.
  7. Now run the unit for 30 minutes.

Do not attach any hose or tools to the compressor during this period. Open the oil drain extension cap to drain the oil after an hour. This will ensure the maximum service life of the machine.

Bleeding the air out

After you have done the breaking-in part, you have to bleed the air out. You have to do it even if you haven’t broken-in the pump. Before getting to the steps, you must ensure that your pressure switch knob is turned to the anticlockwise position.

After that, follow the steps below-

  1. Turn the pressure switch lever to the off position.
  2. Unplug the power cord.
  3. Slowly turn the pressure switch knob clockwise to its maximum position.
  4. Wait until all air pressure is released.

Do not go to the next step unless the tank pressure is zero. After you have a zero reading in the tank pressure gauge, turn back the pressure switch knob anticlockwise to its maximum position.

Operation process

This is the final part where you use your tool.

  1. Attach the air hose to the outlet port of the regulator. It is better if you use a coupler here.
  2. Now, attach your air tool to the other end of the hose.
  3. Plugin the power cord.
  4. Turn the pressure switch lever to the auto position. This will start the air compression.
  5. Keep an eye on the tank pressure gauge. When it reaches the maximum pressure limit, continue to the next step.
  6. Turn the regulator pressure switch knob to your desired pressure level.
  7. Now you can use the tool.
  8. After you have finished your work, turn the pressure switch lever to the off position.
  9. Bleed the air if you are not going to use the compressor for a while.
  10. Drain any water or vapor from the tank with the drain valve.

The final three steps are very important for the well-being of the compressor. Follow them strictly.

In the Campbell Hausfeld store, the most famous Campbell Hausfeld products are-

  • Campbell Hausfeld’s 8-gallon air compressor
  • Campbell Hausfeld 8-gallon horizontal air compressor

Our process will easily go with these compressors. They are especially better with Campbell Hausfeld air compressor tools and impact wrenches.

More Information on Maintenance and Operation

Here are some misfits that I had to write to make it a complete guide.

Campbell Hausfeld Air Compressor

Electrical configuration

Be very careful about the voltage and amp requirements. Make sure you have the correct voltage and amp outlet for the compressor. Any mistake here can cause a big accident. If you don’t have the correct configuration, call the electrician to change it.

Some of the dual volt pumps can be used with both 120 volts and 240 volts. They are shipped from the manufacturers with 120 volts. You can change them in the switch box.

Meter motor controls

The electric motor has built-in overload protection that trips and shuts down the motor when an electric overload occurs. You can reset a tripped overload protection system with the red switch marking it. But if it trips repeatedly, you need to see an electrician.

Pressure rating of the system

Your pipes, tubes, or hoses that are used with the system must be able to withstand the maximum pressure rating of the compressor or at least 150psi. The pipe size should be a minimum of 50 feet long with a half-inch diameter. Larger the diameter, the better it is. More than 50 feet should have a diameter of three-quarters of an inch.


Some of the compressors will need oil. Check if the oil drain extension is installed or not. If not, there might be an oil drain plug. In that case, remove it and install the drain extension. Use thread sealant tape to avoid leaks. Cap the extension before pouring oil.

Always use industrial-grade SAE 30 compressor oil. You can even use the full synthetic motor oil. Mobil 1 10W-30 is a good example of such motor oils. Using regular automotive oil as the 10w30 could clog up your system with sediments.

Some More Safety Tips

Although compressors are innocent machines, using them improperly can have some safety issues. We have already described some of the measures against the safety risks in the article. Those that were not mentioned are here-

  • Use it in a clean and dry place.
  • Don’t forget to use eye protection glasses while operating.
  • Use an additional air hose rather than using an extension cord.
  • Make sure your electrical outlet is grounded correctly, which will ensure your safety; otherwise you may get an electric shock.
  • Always check hoses and oil levels as well as wirings before use.
  • If you see an oil leak, you must use sealant tapes to the threads on each oil draining extension end.

That sums up everything you need to know for operating the Campbell Hausfeld air compressor safely.


You might have noticed that the article had more safety and maintenance points than the actual operation. That is because the operation is basically the use of tools. The main part of using the Campbell Hausfeld air compressor is in the pre and post operational activities.
