Replace the air filter
1. Pull the old filter away from the compressor
It may be jammed into the air box, so use a little force and it should come right out.
2. Install the new air filter
The new filter will be installed the same way the old one was removed-- use your fingers to evenly place the air filter back into the air box.

Turn on the compressor for a few minutes to heat up the oil so it drains easier.

4. Replace the drain plug
Once the oil has drained, replace the drain plug securely.
5. Add new oil to the compressor
Consult your compressors owners manual to find out how much oil you need to add -- then add the appropriate amount of oil to the compressor.

This will be screwed back into its original location where the oil was just added.
