Slide the spring-loaded collar on the compressor's female coupler backward, away from the open end of the coupler.
Insert the hose's male coupler firmly into the compressor's female coupler.
Release the collar on the compressor's female coupler. Check to see that it has returned to the original position, holding the hose's male coupler in place.
Pull on the hose slightly to verify that the connection is secure.
Repeat the steps, connecting the female coupler on the hose to the male coupler on the tool.
- If the compressor is full of compressed air when you insert the hose into the coupler, you should hear the hose fill with air.
