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.
XM plural-component sprayers are operated via user
interface, air controls, and fluid controls.
Isocyanate Hazard
Material Self-Ignition
Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two component
urethane 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 contam-
inated from the other side.
• Always park pumps when you shutdown.
• Always lubricate threaded parts with Part 217374
ISO pump oil or grease when reassembling.
XM OEM sprayers are not approved for use in hazard-
ous locations.
Spraying materials containing isocyanates creates
potentially harmful mists, vapors, and atomized partic-
ulates.
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 ventila-
tion 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 per-
sonal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
Some materials may become self-igniting if applied
too thick. Read material manufacturer’s warnings and
material MSDS.

Components A and B
IMPORTANT!
Material suppliers can vary in how they refer to plural
component materials.
Be aware that in this manual:
Component A refers to resin or major volume.
Component B refers to the hardener or minor volume.
NOTE:
This equipment doses the B component into the A com-
ponent flow. An integration hose must always be used
after the mix manifold and before the static mixer.
NOTE:
Please follow these recommendations for setup:
• use at least a 3/8 in. (10 mm) x 25 ft. (7 m) hose as
the integration hose.
• install a 24-element static mix tube after the integra-
tion hose.
Keep Components A and B Separate
Changing Materials
• When changing materials, flush the equipment mul-
tiple times to ensure it is thoroughly clean.
• Always clean the fluid inlet strainers and outlet filter
after flushing, Flush Mixed Material, page 16.
• Check with your material manufacturer for chemical
compatibility.
• Epoxies often have amines on the B (hardener)
side. Polyureas often have amines on the A (resin)
side.
NOTE:
If the amine will switch between the two sides, see
Flush Mixed Material, page 16.
Location
Grounding
Ground control box (ground wire attached) and both air
motors to a true earth ground.
NOTE:
If wall power is used, ground electrical connection prop-
erly according to local codes.
NOTICE
To prevent cross-contamination of the equipment’s wet-
ted parts, never interchange component A (resin) and
component B (hardener) parts.
XM OEM sprayers are not approved for use in hazard-
ous locations.
