The following general warnings are for the setup, use, grounding, maintenance, and repair of this
equipment. Additional, more specific warnings may be found throughout the body of this manual
where applicable. Symbols appearing in the body of the manual refer to these general warnings.
When these symbols appear throughout the manual, refer back to these pages for a description
of the specific hazard.
WARNING
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in
the operating area of the equipment to help protect you from serious injury, including
eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes
but is not limited to:
• Protective eyewear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
• Gloves
• Hearing protection
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 appli-
cable guidelines.
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.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and
before cleaning, checking, or servicing equipment.
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon
solvents or fluids containing such solvents in pressurized aluminum equipment. Such
use can cause serious chemical reaction and equipment rupture, and result in death,
serious injury, and property damage.

Warnings
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or
explode. 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).
• 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.
• Ground all equipment in the work area. 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 equipment until you identify and correct the problem.
• Keep a fire extinguisher in the work area.
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 Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Tech-
nical Data in all equipment manuals. Read fluid and solvent manufacturer’s warn-
ings. For complete information about your material, request MSDS forms from
distributor or retailer.
• Check equipment daily. Repair or replace worn or damaged parts immediately with
genuine Graco/Gusmer replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your Graco/Gusmer distributor for
information.

Grounding
Grounding
Ground all solvent pails used when flushing,
following your local code. Use only metal pails,
which are conductive, placed on a grounded
surface. Do not place pail on a nonconductive
surface, such a paper or cardboard, which
interrupts grounding continuity.
To maintain continuity when flushing or reliev-
ing pressure, hold a metal part of spray gun
firmly to side of grounded metal pail.
