Warnings
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 or fluids containing such solvents.
• Many other fluids may contain chemicals that can react with aluminum. Contact your material
supplier for compatibility.
PLASTIC PARTS CLEANING SOLVENT HAZARD
Many solvents can degrade plastic parts and cause them to fail, which could cause serious
injury or property damage.
• Use only compatible water-based solvents to clean plastic structural or pressure-containing
parts.
•SeeTechnical Data in this and all other equipment instruction manuals. Read fluid and
solvent manufacturer’s MSDSs and recommendations.
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 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. Alterations or modifications may void agency approvals
and create safety hazards.

6333024A

Important Isocyanate Information
Important Isocyanate Information
Isocyanates (ISO) are catalysts used in two component materials.
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 thick. 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:
•Never interchange component A and component
B wetted parts.
• Never use solvent on one side if it has been
contaminated from the other side.
Moisture Sensitivity of Isocyanates
Exposure to moisture (such as humidity) will cause
ISO to partially cure; forming 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
NOTICE
Partially cured ISO will reduce performance and
the life of all wetted parts.
• 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 pump wet cup or reservoir (if
installed) filled with appropriate lubricant. The
lubricant creates a barrier between the ISO and
the atmosphere.
• Use only moisture-proof hoses compatible with
ISO.
• Never use reclaimed solvents, which may
contain moisture. Always keep solvent
containers closed when not in use.
• Always lubricate threaded parts with an
appropriate lubricant when reassembling.
333024A 7

Important Isocyanate Information
Foam Resins with 245 fa Blowing
Agents
Some 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.
Changing Materials
NOTICE
Changing the material types used in your
equipment requires special attention to avoid
equipment damage and downtime.
• When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
• Always clean the fluid inlet strainers after
flushing.
•Checkwith
your material manufacturer for
chemical compatibility.
• When changing between epoxies and urethanes
or polyureas, disassemble and clean all fluid
components and change hoses. Epoxies often
have amines on the B (hardener) side. Polyureas
often have amines on the B (resin) side.
