Warning! Do not allow open flame or sparks near propane. Propane is extremely flammable, which could cause death or serious injury.
Warning! Read and follow warnings and directions on propane bottle. Failure to follow warnings and directions can result in death or serious injury.
Notes:
- To prevent false readings, keep air cleaner cover installed when performing test.
- Do not direct propane into air cleaner. It will cause false readings.
- Be careful when testing vehicle with Screamin' Eagle air cleaner assembly. This type of air cleaner has an open backplate. Even with air cleaner cover on, directing nozzle too close to backplate can give false readings.
