There was once a time when only mechanics and other trained individuals were the only ones who used air compressors. This is no longer the case. A lot of tools we use at home use air compressors. Some of the tools that use air compressors include painting tools, some sanding equipment, and air wrenches. Air compressors may vary in size and function, but they all share the same operating procedures.
Some unfortunate accidents can occur when using an air compressor and thus special attention must be paid to the pressure gauges when working with an air compressor. This article gives important tips on how to safely use an air compressor.
All compressors must be operated following a specific procedure; here it is.
Before you plug in the compressor, place it on a level and stable surface. Ensure that the compressor is not wobbly. Plug it into a functioning power outlet and turn the power on.
Most compressors are piston driven. Such a compressor uses oil to generate pressure. Before the compressor can be used, check the oil compartment to make sure that there is sufficient oil. If you think the oil level is too low, unscrew the oil compartment cap and fill up the tank. Make sure you check the oil level before each use.
Close the valve under the tank. Use a wrench to tighten it properly. Always keep the area around the valve greased to prevent the valve from getting stuck. After you close the valve, turn on the power and let the compressor fill up. Keep your eye on the pressure gauges at all times. When the pressure gauge indicates 110 psi, switch off the power. Larger compressors require more pressure so it will depend on the model. Some compressors automatically switch off when it reaches the right pressure, but it is always prudent to watch the gauges yourself.
The tool with which you will be using the air compressor has a specified air pressure limit. Use the air control valve on the compressor to match the air pressure allowed on the attached air tool. This is important to protect the tool from excess pressure, especially if you are using a large air compressor with a small tool. Connect a long air hose to the compressor. Use Teflon tape to secure the hose to the air tank. Attach the pneumatic tool to the air hose and use more Teflon tape to ensure the connection is airtight. The tool is now ready for use.
