EQUIPMENT MISUSE HAZARD
Any misuse of the equipment or accessories, such as overpressurizing, modifying parts, using incompatible
chemicals and fluids, or using worn or damaged parts, can cause them to rupture and result in splashing in
the eyes or on the skin, other serious injury, or fire, explosion or property damage.
D This equipment is for professional use only. Observe all warnings. Read and understand all instruction
manuals, warning labels, and tags before you operate this equipment. If you are not sure, or if you have
questions about installation or operation, call Graymills Corporation.
D Never alter or modify any part of this equipment; doing so could cause it to malfunction.
D Check all equipment regularly and repair or replace worn or damaged parts immediately.
D Never exceed the recommended working pressure or the maximum air inlet pressure stated on your pump
or in the Technical Data on page 24.
D Do not exceed the maximum working pressure of the lowest rated component in your system. This
equipment has a 120 psi (0.8 MPa, 8 bar) maximum working pressure at 120 psi (0.8 MPa, 8 bar, )
maximum incoming air pressure.
D Be sure that all fluids and solvents used are chemically compatible with the wetted parts shown in the
Technical Data on page 24. Always read the manufacturer’s literature before you use fluid or solvent in
the pump.
D Never move or lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the
Pressure Relief Procedure on page 11 before you move or lift the pump.
FIRE AND EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the pump and hose. If the equipment is not properly
grounded, sparking may occur. Sparks can ignite fumes from solvents and the fluid being pumped, dust
particles, and other flammable substances, whether you are pumping indoors or outdoors, and can cause a
fire or explosion and serious injury and property damage.
D To reduce the risk of static sparking, ground the pump and all other equipment used or located in the
work area. Check your local electrical code for detailed grounding instructions for your area and type of
equipment. See Grounding on page 5.
D If you experience any static sparking or even a slight shock while using this equipment, stop pumping
immediately. Check the entire system for proper grounding. Do not use the system again until you have
identified and corrected the problem.
D Pipe and dispose of the exhaust air safely, away from all sources of ignition. If the diaphragm fails, the
fluid is exhausted along with the air. See Air Exhaust Ventilation on page 10.
D Do not smoke in the work area. Do not operate the equipment near a source of ignition or an open flame,
such as a pilot light.
