Air Cap Removal

Step 1. Remove the fluid control and needle spring.

Step 2. Engage the trigger and remove the needle.

Step 3. Loosen the air cap collar and remove the air cap.

Step 4. Using the #12 cut-out on the wrench that came with your spray gun, remove the fluid nozzle.

Step 2. Install the air cap and secure the collar.

Step 3. Install your needle, needle spring, and fluid control.
