Learn how to use an air compressor in 8 simple steps below!
Step 1. Position Air Compressor Properly
- Find a flat and stable area to place your air compressor on.
- Refrain from putting the air compressor on any surface that feels uneven or flimsy.
- Connect the power cord to a grounded electrical outlet nearby. Make sure the power is turned off.
- Do not use the compressor in an outlet that isn’t grounded.
Step 2. Check Oil Level
- Manually check your air compressor’s oil level.
- Most piston-type portable compressors have a gauge near the motor that will give an oil level reading.
- Remove the oil cap and add oil to the specified mark, if necessary.
- Check the compressor instructions if oil level cannot be determined.
Step 3. Check The Drain Valve
- Check the drain valve which is typically located at the bottom of the air tank.
- You’ll want the valve to be completely closed.
- If the valve is slightly open, it can be tightened with an adjustable wrench.
Step 4. Prepare Air Tank
- Start by flipping the power switch to the “on” position.
- Let the compressor run for at least one minute.
- Monitor the air pressure gauge and make sure the compressor switches off when the pressure capacity is reached.
- Make note that the air pressure is measured by PSI.
Step 5. Set PSI
- Using the air control valve, adjust the maximum PSI of the compressor.
- Adjust the pressure until the recommended air pressure for a specific tool is reached.
- Several adjustments may need to be made to achieve desired air flow.
Step 6. Connect Air Hose
- Begin by attaching the air hose to the air compressor.
- If you are unsure where to attach the air line, check the manual.
- If required, wrap the threaded end of the hose. You may need to wrap the hose with PTFE tape, depending on the compressor model.
- Use an adjustable wrench to tighten the hose, locking it in place.
Step 7. Connect Desired Tool
- Connect the tool you have been working with to the other end of the air hose.
- Pull the protective collar back on the hose and attach it to the air intake valve located on the tool.
- Releasing the collar will secure the connection in place.
- You will need to pull back on the neck collar when it comes time to remove the tool.
Step 8. Remove Excess Moisture
- Removing moisture periodically after use is a necessity.
- Remove the drain valve at the bottom of the tank with a wrench.
- Make sure to check the manual before removal.
