The Bombardier fogging oil can does not come with the adapter hose which you will need to connect to the Schrader valve. Your local dealer sells it under part number: 763644 Once you have the hose, the instructions on the can should be sufficient. You will need to turn the red lever 90 degrees while fogging in order to open the valve for the admission of the fogging oil. That puts the red lever in the "service" position. Be sure to turn the red lever back to the "run" position after the fogging is complete. You'll need to run the engine at a high idle, as the fogging oil will likely slow the idle such that it will shut off.
