    Disclaimer on High Pressure Air (HPA) Systems:

    HPA Tanks are a safe and effective source of power though there are some precautions you must follow. Please follow these proper precautions when using HPA systems:

    - NEVER put oil in the fill valve of the tank, or else the tank can combust on refill and serious injury can occur. Lubrication is not necessary in HPA systems.
    - ONLY allow properly trained professionals to fill your HPA tank.
    - ALWAYS double check your Regulator pressure. Never raise the regulated pressure above 120 PSI
    - Make sure to have your tank Hydro-Tested when necessary. (Usually 3-5 years from date marked on tank, depending on make and model)
    - Be sure to properly transport your HPA tank. Store in a safe, secured place when in a vehicle, and be sure to stow in a bag or tank cover when in use. Avoid dropping the tank on hard surfaces as this can seriously damage the tank and lead to failure.
    - Always turn off the tank and bleed the air line when you are done. This will ensure a longer tank and system lifespan.
