Warnings
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-speci c
risks. When these symbols appear in the body of this manual or on warning labels, refer back to these
Warnings. Product-speci c hazard symbols and warnings not covered in this section may appear throughout
the body of this manual where applicable.
WARNING
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the system can
cause electric shock.
• Turn off and remove power before disconnecting any cables and before servicing or installing
equipment. For cart-mounted models, unplug the power cord. For all other units, disconnect
power at the main switch.
• Connect only to grounded power source.
• All electrical wiring must be done by a quali ed electrician and comply with all local codes
and regulations.
• Wait ve minutes for capacitor discharge before opening equipment.
• For cart-mounted models, use only 3-wire extension cords.
• For cart-mounted models, ensure ground prongs are intact on any power and extension cords.
• For cart-mounted models, do not expose to rain. Store indoors.
FIRE A D EXPLOSIO HAZARD
Flammable fumes, such as solvent and paint fumes, in work area canigniteorexplode.Paint
or solvent flowing through the equipment can cause static sparking. To help prevent re 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).
• Ground all equipment in the work area. See Grounding instructions.
• 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.
• 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 re extinguisher in the work area.
Static charge may build up on plastic parts during cleaning and could discharge and ignite
flammable vapors. To help prevent re and explosion:
• Clean plastic parts only in well ventilated area.
• Donotcleanwithadrycloth.
• Do not operate electrostatic guns in equipment work area.

Warnings
WARNING
PRESSURIZED EQUIPME T HAZARD
Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin
and cause serious injury.
• Follow the Pressure Relief Procedure when you stop spraying/dispensing 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.
EQUIPME T 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 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. For complete
information about your material, request Safety Data Sheet (SDS) from distributor or retailer.
• 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.

Warnings
WARNING
THERMAL EXPA SIO HAZARD
Fluids subjected to heat in con ned spaces, including hoses, can create a rapid rise in pressure
due to the thermal expansion. Over-pressurization can result in equipment rupture and serious
injury.
• Openavalvetorelievethefluidexpansionduringheating.
• Replace hoses proactively at regular intervals based on your operating conditions.
PLASTIC PARTS CLEA I G SOLVE T HAZARD
Many solvents can degrade plastic parts and cause them to fail, which could cause serious
injury or property damage.
• Use only compatible water-based solvents to clean plastic structural or pressure-containing
parts.
•See Technical Data in this and all other equipment instruction manuals. Read fluid and
solvent manufacturer’s Safety Data Sheet (SDS) and recommendations.
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 Sheet (SDS) to know the speci c hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable
guidelines.
BUR HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid
severe burns:
• Do not touch hot fluid or equipment.
PERSO AL PROTECTIVE EQUIPME T
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. This protective

Key Points:
• Pumps are available with an AC or Brushless
DC (BLDC) motor, or with just a gearbox (for
applications where a motor already is available).
• Graco recommends the use of a motor soft
starter or a VFD (PN 16K911 or 16K912) in the
electrical circuit for all installations. See the
motor manufacturer’s recommendations for proper
installation when using either of these components.
In all cases, make sure all products are installed in
accordance with local codes and regulations.
• BLDC motors are controlled by the Graco Motor
Control that is supplied with the pump.
• The standard AC motor (not ATEX or
Explosionproof) and the BLDC motor are available
in models without a compressor, with a 120V
compressor, or with a 240V compressor.
• The BLDC motor is available in models that
are cart mounted. Cart Mounting Kit 24Y543 is
available for other models.

Problem Cause Solution
Pump is running too fast, causing
cavitation before prime. Slow down the motor controller (VFD or Graco Motor Control)
Center section has no air pressure,
or air pressure is too low. Apply air pressure to center section
per your application requirements.
Check valve ball is severely worn or
wedged in seat or manifold. Replace the ball and seat.

Seat is severely worn. Replace the ball and seat.
Outlet or inlet is restricted. Remove therestriction.
Inlet ttings or manifolds are loose. Tighten.
Pump cycles but will not prime
and/or pump.
Manifold o-rings are damaged. Replace o-rings.
