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-specifi c hazard s y mbo ls and warni ngs not cov ered in this section may appea r 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 ground ed power source.
• A l l electrical wiring must be done b y a qu al ifi ed electrici an and comply wi th all local c odes
and regulations.
• Wait five minutes for capacitor disc harge before opening equipment.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in
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 arc).
• Ground all equipment in the work area. See
• 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
equipment until you identify and correct the problem.
• K ee p a working fire ext ingui sh er in the work area.
Static charge may build up on plastic parts during c leaning and could discharge and ignite
flammable vapors. To help prevent fi re and explosion:
• Clean plastic parts only in well ventilated area.
• Donotcleanwithadrycloth.
• Do not operate electrostatic guns in equipment work area.

WARNING
PRESSURIZED EQUIPMENT HAZARD
Fluid from the equipment, leaks, or rup tured compo nents ca n splash in the eyes or on skin
and cause serious injury.
• Follow the
cleaning, checkin g, or servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immedia tely.
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
• Use fluids and solvents that are compatible with equipment wetted parts. See
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
• 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.

PRESSURIZ E D ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can caus e serious
chemical reaction and equipment rupture. Failure to follow this warning can result in death,
serious injury, or property damage.
• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon
solvents or fluids containing such solvents.
• Do not use chlorine bleach.
• Many other fluids may contain chemicals that can react with aluminum. Contact your material
supplier for compatibility.

WARNING
THERMAL EXPANSION HAZARD
Fluids subjected to heat in confined spaces, including hoses, c an 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 CLEANING SOLVENT HAZARD
Many solvents can degrade plastic parts and cause them to fail, which could c ause se rious
injury or property damage.
• Use only compatible water-based solvents to clean plastic structural or pressure-contain ing
parts.
•See

in this and all other equipment instruction manuals. Read fluid and
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 specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable
guidelines.
BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operati on. To avoid
severe burns:
• Do not touch hot fluid or equipment.
PERSONAL PROTECTIV E 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. This 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.

Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure
is relieved manually. To help prevent serious
injury from pressurized fluid, such as splashing
in the eyes or on skin, follow the Pressure Relief
Procedure when you stop pumping and before you
clean, check, or service the equipment.
1. Remove power from the system.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve to relieve fluid
pressure. Have a container ready to catch the
drainage.
4. Back out regulator knob to bleed any internal
air pressure.
Check Valve Repair
Disassemble the Check Valve
1. Follow the Pressure Relief Procedure, page 11.
Remove power from the motor. Disconnect all
hoses.
