New Compressor questions

1. That knob adjusts air flow to the tool you are using.

2. The red canister is a particulate/moisture filter to keep stuff out of your tools.

3. Not sure.

4. You should use a couple of drops of oil in ANY air tool you hook up. Use air tool oil for the tools. Just put 2 drops in the chuck where the air line hooks up each time you use the tool.
