WARNING
INSTRUCTIONS
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.
•This equipment is for professional use only. Observe all warnings. Read and understand all
instruction manuals, warning labels, and tags before operating the equipment.
•Never alter or modify any part of this equipment; doing so could cause it to malfunction. Use only
genuine Graco parts and accessories.
•Check all equipment regularly and repair or replace worn or damaged parts immediately.
•Never exceed the recommended working pressure or the maximum air inlet pressure stated on your
pump or in the Technical Data on page 36.
•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.
•Be sure that all fluids and solvents used are chemically compatible with the wetted parts shown in
the Technical Data on page 36. Always read the manufacturer’s literature before using fluid or
solvent in the pump.
•Never move or lift a pump under pressure. If dropped, the fluid section may rupture. Always follow
the Pressure Relief Procedure on page 12 before moving or lifting the pump. The pump is very
heavy. If it must be moved, have two people lift the pump by grasping the outlet manifold securely.

HAZARDOUS FLUIDS
Improper handling of hazardous fluids or inhaling toxic vapors can cause extremely serious injury, even
death, due to splashing in the eyes, ingestion, or bodily contamination. Observe all the following
precautions when handling known or potentially hazardous fluids.
•Know what fluid you are pumping and its specific hazards. Take precautions to avoid a toxic fluid
spill.
•Always wear appropriate clothing and equipment, such as eye protection and breathing apparatus,
to protect yourself.
•Store hazardous fluid in an appropriate, approved container. Dispose of it according to all Local,
State and Federal guidelines for hazardous fluids.
•Secure the fluid outlet hose tightly into the receiving container to prevent it from coming loose and
improperly draining the fluid
•Pipe and dispose of the exhaust air safely, away from people, animals, and food handling areas. If
the diaphragm fails, the fluid is exhausted along with the air. See Air Exhaust Ventilation on
page 11.
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.
•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. Refer to Grounding on page 6.
•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 the problem has been identified and corrected.
•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 11.
•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.
HALOGENATED HYDROCARBON HAZARD
Never use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids
containing such solvents in Aluminum Pumps. Such use could result in a serious chemical reaction, with
the possibility of explosion, which could cause death, serious injury and/or substantial property damage.
Consult your fluid suppliers to ensure that the fluids used are compatible with aluminum parts.
