Cleaning Solutions
Prepare the cleaning solution according to the manufac- turer’s instructions. Be sure to observe all warnings. If you are using powdered cleaners, mix them thoroughly in a separate pail before adding them to a supply drum. Undissolved powders are extremely abrasive and may damage pump parts.
Wear appropriate protective clothing, such as water- proof outerwear and eye goggles, according to the cleaner manufacturer’s recommendations. Cleaning chemicals may be toxic, and cause serious irritation to your eyes or skin.
Flushing
To reduce the risk of fluid injection injury, static spark- ing, or splashing, relieve the pressure, and remove the spray tip (spray guns only) before flushing.
Hold a metal part of the gun/valve firmly to the side of a grounded metal pail and use the lowest possible fluid pressure during flushing.
