Hey everyone! I'm fairly new to using air compressors and I'm trying to figure out why my M18 compressor is losing air pretty fast after I fill the tank. I'm keen on learning how to handle basic repairs myself, so any tips or things I should check to pinpoint the issue would be really helpful. Thanks a lot!

If your M18 compressor is losing air quickly, don't worry, it's usually straightforward to find the leak. Here are a few things you can check:
1. First, disconnect your hose and any tools to see if the leak is coming from the compressor itself.
2. Pull the relief valve a few times; sometimes dirt can get stuck on the seat causing issues.
3. Ensure the drain valve is completely closed.
4. Inspect the hoses and clamps for any cracks or damage.
5. Lastly, check the quick-disconnect coupler on the output.
You could also try spraying soapy water on all the connections and fittings; bubbles will show you where the air is escaping from! Good luck!

Thanks for the tips! I’ll give those a try. I would think I’d hear the leak if there was one, but I can’t hear anything. I'll keep an ear out, too!
