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 symbol refers to procedure-specific risk. Refer back to these
warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.
WARNING
ELECTRIC SHOCK HAZARD
Improper grounding, setup, or usage of the system can cause electric shock.
• Turn off and disconnect power cord before servicing equipment.
• Use only grounded electrical outlets.
• Use only 3-wire extension cords.
•
Ensure ground prongs are intact on sprayer and extension cords.
•
Do not expose to rain. Store indoors.
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 applicable guidelines.
• Always wear impervious gloves when spraying 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 is not limited to:
•
Protective eyewear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
• Gloves
• Hearing protection
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.
• Close material shutoff valves and shutoff or disconnect air supply when not spraying.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.
3
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.
• 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.
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.
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 Technical Data 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 work area.
• Comply with all applicable safety regulations.
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.
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 cooled completely.
4
Warnings
To prevent exposing ISO to moisture:
Isocyanate Hazard
Spraying 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
Isocyanates
of
Isocyanates (ISO) are catalysts used in two component
foam and polyurea 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.
5
•
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 filled with Graco
Throat Seal Liquid (TSL), Part 206995. 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 closed when
not in use.
•
Never use solvent on one side if it has been contaminated from the other side.
•
Always park pumps when you shutdown.
•
Always lubricate threaded parts with Part 217374 ISO
pump oil or grease when reassembling.
Warnings
Keep Components A and B
Separate
Changing Materials
•
When changing materials, flush the equipment multiple times to ensure it is thoroughly clean.
CAUTION
•
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.
•
Epoxies often have amines on the B (hardener) side.
Polyureas often have amines on the B (resin) side.
To prevent cross-contamination of the equipment’s wetted parts, never interchange component A (isocyanate)
and component B (resin) partrs. The gun is shipped with
the A side on the left. The fluid manifold, fluid housing, side seal assembly, check valve cartridge, and mix
chamber are marked on the A side.
Foam Resins with 245 fa
Blowing Agents
New foam blowing agents will froth at temperatures above
90°F (33 °C) when not under pressure, especially if agitated. To reduce frothing, minimize preheating in a circulation
system.
