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, refer back to these Warnings. Additional, product-specific warnings
may be found throughout the body of this manual where applicable.
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 working fire 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 fire and explosion:
•Clean plastic parts only in a well ventilated area.
•Do not clean with a dry cloth.
•Do not operate electrostatic guns in equipment work area.
SPECIAL CONDITIONS FOR SAFE USE
Equipment must comply with the following conditions to avoid a hazardous condition which can cause fire
or explosion.
•All label and marking material must be cleaned with a damp cloth (or equivalent).
•The electronic monitoring system is required to be grounded. See Grounding instructions.

WARNING
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 ser-
vicing equipment.
•Tighten all fluid connections before operating the equipment.
•Check hoses and couplings daily. Replace worn or damaged parts immediately.
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 compo-
nent. 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 MSDS 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.
•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.
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.
•Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow the Pressure Relief Procedure and disconnect all power sources.
SUCTION HAZARD
Powerful suction could cause serious injury.
•Never place hands near the pump fluid inlet when pump is operating or pressurized.

WARNING
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 MSDSs 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.
•Always wear chemically impermeable gloves when spraying, dispensing, or cleaning equipment.
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, hearing loss, inhalation of
toxic fumes, and burns. This 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.

Isocyanate Conditions
Spraying or dispensing materials containing isocyanates creates potentially harmful mists, vapors, and
atomized particulates.
Read material manufacturer’s warnings and material
MSDS to know specific hazards and precautions
related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufficient ventilation in the work area. If sufficient ventilation is not
available, a supplied-air respirator is required for
everyone in the work area.
To prevent contact with isocyanates, appropriate personal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
Material Self-ignition
Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.
Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two component
coatings. ISO will react with moisture (such as humidity)
to form small, hard, abrasive crystals, which become
suspended in the fluid. Eventually a film will form on the
surface and the ISO will begin to gel, increasing in viscosity. If used, this partially cured ISO will reduce performance and the life of all wetted parts.
NOTE: The amount of film formation and rate of crystallization varies depending on the blend of ISO, the
humidity, and the temperature.
To prevent exposing ISO to moisture:
•Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere. Never
store ISO in an open container.
•Use moisture-proof hoses specifically designed for
ISO, such as those supplied with your system.
•Never use reclaimed solvents, which may contain
moisture. Always keep solvent containers closed
when not in use.
•Never use solvent on one side if it has been contaminated from the other side.
•Always lubricate threaded parts with ISO pump oil
or grease when reassembling.
Changing Materials
Keep Components A and B
Separate
Cross-contamination can result in cured material in
fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination of
the equipment’s wetted parts, never interchange
component A (isocyanate) and component B (resin)
parts.

•When changing materials, flush the equipment multiple times to ensure it is thoroughly clean.
•Always clean the fluid inlet strainers after flushing.
•Check with your material manufacturer for chemical
compatibility.
•Most materials use ISO on the A side, but some use
ISO on the B side.
