Warnings
308360D 3
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The
exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks.
When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings.
Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this
manual where applicable.
WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Specifications in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical
Specifications in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For
complete information about your material, request Safety Data Sheets (SDSs) from distributor or
retailer.
• Do not leave the work area while equipment is energized or under pressure.
• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine
manufacturer’s replacement parts only.
• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create
safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
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 spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• 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.
• Follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or
servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace worn or damaged parts immediately.

Warnings
4 308360D
MOVING PARTS HAZARD
Moving parts can pinch, cut or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Equipment can start without warning. Before checking, moving, or servicing equipment, follow the
Pressure Relief Procedure and disconnect all power sources.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or
solvent flowing through the equipment can cause static sparking. To help prevent 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 sparking).
• Ground all equipment in the work area. See Grounding instructions.
• Never spray or flush solvent at high pressure.
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they
are anti-static or conductive.
•Stop operation immediately if static sparking occurs or you feel a shock.Do not use equipment until
you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
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 Safety Data Sheets (SDSs) to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including
eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes but is not
limited to:
• Protective eyewear, and hearing protection.
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.
WARNING

Installation
308360D 5
Installation
Grounding
Pump: use ground wire and clamp (supplied). Loosen
grounding lug locknut (LL) and washer (LW). Insert one
end of a 1.5 mm2(12 ga) minimum ground wire end
(GW) into lug (LS) slot and tighten locknut securely.
Connect ground clamp to a true earth ground. Order
part 237569 ground wire and clamp.
Air and fluid hoses: use only electrically conductive
hoses. Check electrical resistance of hoses. If total
resistance to ground exceeds 29 megaohms, replace
hose immediately.
Air compressor: follow manufacturer’s
recommendations.
Spray gun: ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
Accessories
Install the following accessories in the order shown in
FIG. 1, page 7, using adapters as necessary. Contact
your Graco representative or Graco Technical
Assistance for assistance in designing a system to suit
your needs.
Air and Fluid Hoses
Be sure all air hoses (H) and fluid hoses (N and P) are
properly sized and pressure-rated for your system. Use
only electrically conductive hoses. Fluid hoses must
have spring guards on both ends. Use a whip hose (P)
and a swivel (R) between the main fluid hose (N) and
the gun (S) to allow freer gun movement
Mounting Accessories
Mount the pump (A) to suit the type of installation
planned. FIG. 1, page 7, illustrates a wall mount system.
See Dimensions and Mounting Hole Layout, page 23.
If you are using a floor stand, refer to its separate
manual for installation and operation instructions.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
