hazard symbol refers to procedure-specific risk. Refer back to these
warnings. Additionally, product-specific warnings may be found 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 disconnect power at main switch before
disconnecting any cables and before servicingequipment.
• Connect only to grounded power source.

comply with all local codes andregulations.
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 to know the specific hazards of the fluids you are
using.
• Store hazardous fluid in approved containers, and dispose of it
according to applicableguidelines.
• 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, inhalation of toxic
fumes, burns, and hearing loss. This equipment includes but not limited
to:

WARNING
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leak, 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 treatment.
• Engage raw material valve lock when notspraying.
• 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.
• Turn off the machine when you stop spraying and before
cleaning, checking, or servicing equipment.
• Tighten all fluid connections before operating theequipment.
• Check hoses and couplings daily. Replace worn or damaged
parts immediately.
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 in well ventilated only.
• Eliminate all ignition sources; such as pilot lights, cigarettes;
plastic drop cloths, and portable electriclamps.
• Keep work area free of debris, including solvent, rags and
gasoline.
• Do not plug or unplug power cords, or turn power or light switch
on or off when flammable fume arepresent.
• Ground all equipment in the workarea.
• Hold gun firmly to side of grounded pail when triggering into
pail.
• If there is a 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 workarea.
THERMAL EXPANSION HAZARD
Fluid subjected to heat in confined spaces, including hoses, can creat
a rapid rise in pressure due to the thermal expansion. Over-
pressurization can result in equipment rupture and serious injury.
• Open a valve relieves the fluid expansion duringheating.
• Replace hosed proactively at regular intervals based on your
operation conditions.

WARNING
PRESSURIZED ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in
pressurized equipment can cause 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 for fluids containing such
solvents.
• Many other fluids may contain chemicals that can react with
aluminum. Contact your material supplier forcompatibility.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• This equipment is for Professional use only.
• Do no leave the work area while the equipment is energized or
under pressure. Turn off all equipment when the equipment is not
in use.
• 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 manual.
• Use fluids and solvents that are compatible with equipment wetted
parts. See Technical Date in all equipment manuals. Read fluid and
solvent manufacturer’s warnings. 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 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 workarea.
• Comply with all applicable safetyregulations.

WARNING
MOVING PARTS HAZARD
Moving parts can pinch 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 in this manual. Disconnect power or air supply.
s
BURN 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.
Wait until equipment/fluid has cooledcompletely.

2. Important Two-Component MaterialInformation
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.

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.
Moisture Sensitivity of Isocyanates
Isocyanates (ISO) are catalysts used in two component foam and polyurethane
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.
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.
• Keep the ISO lube pump reservoir (if installed) filled with DOP. The lubricant
creates a barrier between the ISO and the atmosphere.
• 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 loosed 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
• 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 RED drum, and POLY on the BLUE drum.
