Why is my Porter-Cable Air Compressor not supplying enough air?

If your Porter-Cable Air Compressor isn't providing enough air, consider these possibilities: excessive air usage (decrease it), an undersized compressor (check accessory air requirements and upgrade if needed), a hole in the hose (inspect and replace), a restricted check valve (remove and clean or replace), air leaks (tighten fittings), a restricted air intake filter (clean or replace, ensuring you don't operate without it), or a loose belt (check belt tension).
