  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.

1. Warm up the oil

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

2. Remove the fill-cap

This allows air to enter the tank for easier drainage.

3. Remove the drain plug

Use a wrench to loosen and remove the drain plug. Make sure to have a container ready to catch the old oil that will drain after removing the plug.

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.

6. Replace the fill cap 

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

3. Install the new belt 

 Install the new belt the same way it was removed -- slide the belt onto the pulleys.

4. Reinstall the belt cover 

Set the belt cover back into its original location and fasten it with the bolts or tabs that were removed earlier.
