Operating Instructions
Once set up, your AutoLine Pro smoke machine is ready for leak detection:
1. Prepare the System for Testing:
Identify the system you wish to test (e.g., EVAP, vacuum, intake). Locate an appropriate access point, such as a vacuum line, EVAP port, or intake manifold opening. Ensure the system is sealed as much as possible to contain the smoke.
2. Insert Universal Nozzle:

Attach the universal smoke nozzle to the end of the smoke hose. The tapered design of the nozzle fits into virtually all hoses and lines, providing a secure connection for smoke injection.
3. Start Smoke Diagnostics:

With power and air connected, the machine will begin to produce smoke. Inject the smoke into the system you are testing. The machine is designed to produce 1.5 hours of non-stop smoke per use.
4. Identify Leaks:

Observe for smoke escaping from any part of the system. Common leak points include worn rubber, gaskets, seals, and connectors. The thick smoke output helps detect even the smallest leaks.

The built-in 1-PSI regulator ensures the pressure is safe for all vehicle systems, preventing damage during testing.
Maintenance
Proper maintenance will ensure the longevity and optimal performance of your AutoLine Pro smoke machine:
- Fluid Level: Regularly check the smoke fluid level. Refill as needed with AutoLine Pro smoke fluid or other OEM-approved smoke fluids. Do not allow the reservoir to run dry during operation.
- Cleaning: After each use, wipe down the exterior of the machine with a clean, dry cloth. Ensure no smoke fluid residue is left on external components.
- Storage: Store the smoke machine in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure all fluid is securely capped and hoses are disconnected.
- Fuse Replacement: If the machine fails to power on, check the 10 AMP ATC power fuse. Replace it with the included spare fuse if necessary.
