Air compressors are versatile tools that can be used in various applications. To use an air compressor, start by ensuring that it is properly grounded and connected to a power source. Next, check the oil level and fill it if necessary. Adjust the pressure settings to the desired level and attach the appropriate air tool or accessory. Turn on the compressor and allow it to build up pressure. Once the desired pressure is reached, start using the air tool. Remember to always follow safety guidelines and wear proper protective gear.
Previously, air compressors were only used by professional mechanics and craftsmen, but now they are available in smaller sizes and can be used by anyone. These machines are capable of powering air-powered tools for various applications.
Compressed air is stored in a steel tank and is released in a controlled manner to power a variety of tool attachments. The motor on the compressor pumps air into a storage tank under pressure and maintains it at high pressure to power the tools, which connect to the tank via air hoses. In normal tool operation, the compressor’s motor will kick in and shut off automatically as air pressure fluctuates in the tank. Air compressors can power a whole collection of relatively inexpensive attachments, which can generate more power than many hand-held electrical tools.
Manufacturers such as Sears Craftsman, Porter Cable, Bostitch, DeWalt, Stanley, and Makita sell air compressors. Mechanically, air compressors use one of several design styles, with some having automotive-style pistons that require oil to keep them operating properly. For more modest jobs, diaphragm-style compressors are available, which use no oil but create a seal using a rubber diaphragm. Homeowners prefer oil-less diaphragm compressors as they are useful for operating air nailers, paint sprayers, and other smaller equipment.
Here are some basic instructions for using air compressors:
Step 1: Plug in the Compressor
Place the compressor on a firm, flat work area. Make sure the power switch is turned off. Plug the power cord into a grounded (three-pronged) electrical outlet.
Step 2: Check the Oil
If the compressor is a piston-type, ensure there is enough oil in the crankcase. Check the oil level by peering into the sight gauge at the bottom of the compressor motor. If necessary, remove the oil filler cap and add compressor oil to bring the level up to the full mark on the gauge. Check the oil level after each use.
Step 3: Fill the Air Tank
Make sure the drain valve is closed at the bottom of the air tank by tightening it with an adjustable wrench in a clockwise direction. Turn the power switch on and let the compressor run for a few minutes. Check the built-in air gauge and make sure the compressor shuts off automatically when the air pressure reaches 100 to 115 psi. The pressure capacity of the tank will vary depending on the model.

Overall, air compressors are a useful tool for DIYers and professionals alike.
Step 4: Adjusting the Air Control Valve
To match the maximum allowed air pressure on the air tool that you will be using, adjust the air control valve. Turn the air control valve in either direction until the air pressure gauge reads the correct air pressure for the tool.
Step 5: Connecting the Air Hose
Ensure that the length of the air hose is sufficient to reach the work area and connect it to the compressor. Wrap the threaded end of the air hose with two layers of Teflon tape, and then thread the hose onto the compressor fitting (located near the air pressure gauge). Use an adjustable wrench to tighten it in a clockwise direction. Some compressors may have quick-connect hose fittings to connect to the air tank.
Step 6: Connecting the Pneumatic Tool
To connect your air tool, use the quick-connect fitting at the other end of the air hose. Pull back on the spring-loaded collar on the hose, and push it firmly onto the air intake on the tool. Release the collar to secure the connection. To disconnect the tool, pull back on the collar while pulling the tool off the air hose.
Step 7: Draining Moisture After Use
Periodically drain the moisture from the air tank (check your owner’s manual for recommendations) by loosening and removing the drain valve at the bottom of the tank with an adjustable wrench in a counterclockwise direction. Once all water has drained from the tank, replace the drain valve and tighten it in a clockwise direction.
