Loss of Air Pressure

Loss of Air Pressure

Purge rod actuation is controlled by air pressure. In event of loss of air pressure, the purge rod will remain retracted, the impingement ports will remain open, and the gun will continue to pour. To stop pouring, do one of the following:

•Engage piston safety lock, see Piston Safety Lock section

•Close fluid valves A and B, see FIG. 3

FIG. 3

Hook Support

If necessary, use the hook support located on the top of the gun to support the weight of the gun. Connect a strong rope or chain able to support the weight of the gun to the hook, then connect the other end to a sup- port. This will enable the user to use the gun without having to support the weight of the gun.
