WARNING

Important Isocyanate (ISO) Information
313292K 7
Important Isocyanate (ISO) Information
Isocyanates (ISO) are catalysts used in two component materials.
Isocyanate Conditions Keep Components A and B
Separate
Spraying or dispensing fluids that contain isocyanates
creates potentially harmful mists, vapors, and
atomized particulates.
• Read and understand the fluid manufacturer’s
warnings and Safety Data Sheets (SDSs) to know
specific hazards and precautions related to
isocyanates.
• Use of isocyanates involves potentially hazardous
procedures. Do not spray with this equipment
unless you are trained, qualified, and have read
and understood the information in this manual and
in the fluid manufacturer’s application instructions
and SDSs.
• Use of incorrectly maintained or mis-adjusted
equipment may result in improperly cured
material. Equipment must be carefully maintained
and adjusted according to instructions in the
manual.
• To prevent inhalation of isocyanate mists, vapors,
and atomized particulates, everyone in the work
area must wear appropriate respiratory protection.
Always wear a properly fitting respirator, which
may include a supplied-air respirator. Ventilate the
work area according to instructions in the fluid
manufacturer’s SDSs.
• Avoid all skin contact with isocyanates. Everyone
in the work area must wear chemically
impermeable gloves, protective clothing and foot
coverings as recommended by the fluid
manufacturer and local regulatory authority.
Follow all fluid manufacturer recommendations,
including those regarding handling of
contaminated clothing. After spraying, wash
hands and face before eating or drinking.
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.

Important Isocyanate (ISO) Information
8313292K
Moisture Sensitivity of
Isocyanates
Exposure to moisture (such as humidity) will cause ISO
to partially cure, forming small, hard, abrasive crystal
that become suspended in the fluid. Eventually a film will
form on the surface and the ISO will begin to gel,
increasing in viscosity.
NOTE: The amount of film formation and rate of
crystallization varies depending on the blend of ISO, the
humidity, and the temperature.
Changing Materials
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.
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.
• Check with 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.

Overview
10 313292K
Overview
Usage
XM plural-component sprayers can mix and spray most
two-component epoxy and urethane protective coatings.
When using quick-setting materials (less than 10 minute
pot life) a remote mix manifold must be used.
The XM sprayer operates using compressed air
pressure. XM plural-component sprayers are operated
via the user interface, air controls, and fluid controls.
The models with the alternator control box option
feature an intrinsically safe alternator powered by a
compressed air-fed turbine as a power supply. The
alternator module working pressure must be set to 18
+/- 1 psi (12.6 +/- 10 kPa, 1.26 +/- 0.07 bar).
Location
Grounding
NOTE: If wall power is used, ground the electrical
connection properly according to local codes.
Control box: Connect the control box ground wire (73)
to a true earth ground.
Pump: Connect the ground cable (15) provided on the
back of the control box ground nut to the ground screw
(G). Verify that the ground screw (G) is attached and
tightened securely to the air motor.
Air and fluid hoses: Use only electrically conductive
hoses with a maximum of 500 ft (152 m) combined hose
length to ensure grounding continuity. Check electrical
resistance of hose regularly. If total resistance to ground
exceeds 29 megaohms, replace hose immediately.
Spray gun: Ground through connection to a properly
grounded fluid hose and pump.
Solvent pails: Follow your local code. Use only
conductive metal pails, placed on a grounded surface.
Do not place the pail on a non-conductive surface, such
as paper or cardboard, which interrupts grounding
continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold the metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.
Object being sprayed: Follow your local code.
Fluid supply container: Follow your local code.
Air compressor: Follow manufacturer’s
recommendations.
XM OEM sprayers are not approved for use in
hazardous locations.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape for the electric current.
