Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-
tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back
to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where
applicable.
WARNING
Equipment Misuse Hazard
Misuse can cause death or serious injury.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in
all equipment manuals. Read fluid and solvent manufacturer’s warnings.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your Graco distributor for information.
• For professional use only.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not use hoses to pull equipment.
• Comply with all applicable safety regulations.
PRESSURIZED EQUIPMENT HAZARD
Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin
and cause serious injury.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like
just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.

Warnings
309868E 3
MOVING PARTS HAZARD
Moving parts can pinch or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Pressurized equipment can start without warning. Before checking, moving, or servicing equip-
ment, follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
• Read MSDS’s to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guide-
lines.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help pre-
vent fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic
drop cloths (potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Ground equipment and conductive objects. See Grounding instructions.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use equip-
ment until you identify and correct the problem.

Mounting the Pump
• Select a location that allows the operator easy
access to the pump and air controls, sufficient room
to change supply containers, and a secure
mounting platform.
• If you are mounting the pump directly on the supply
container, be sure it is positioned so the pump’s
intake tube is no more than 1 in. (25 mm) from the
bottom of the container. Mount the pump to the
cover or other suitable mounting device.
Grounding
Proper grounding is essential to maintaining a safe
system.
To reduce the risk of static sparking, ground the pump.
Check local electrical codes for detailed grounding
instructions for your area and equipment type. Be sure
the following equipment is properly grounded:
• Pump: See FIG. 2.
•Air and fluid hoses: Use only electrically conductive
hoses.
•Air compressor: Follow manufacturer’s
recommendations.
•Dispensing valve: Obtain grounding through con-
nection to a properly grounded fluid hose and pump.
•Fluid supply container: Follow your local code.
•Object being lubricated: Follow your local code.
•Any pails used when flushing: Use only metal,
grounded pails when flushing. Make firm
metal-to-metal contact between a metal part of the
dispensing valve and the pail. Use the lowest possi-
ble pressure.
To maintain grounding continuity when flushing or reliev-
ing pressure, always hold a metal part of the valve firmly
to the side of a grounded metal pail, then trigger the
valve.
To ground the pump, remove the ground screw (Z) and
insert through the eye of the ring terminal at end of
ground wire, (Y). Fasten the ground screw back onto the
pump and tighten securely. Connect the other end of the
ground wire to a true earth ground. See FIG. 2. To order
a ground wire and clamp order Part No. 222011.
FIG. 2
Mount the pump securely so that it cannot move
during operation. Failure to do so could result in per-
sonal injury or equipment damage.
To prevent damage to the pump, remove sedi-
ment from the bottom of the container before
installing a pump in an existing container.
