WARNING

Important Isocyanate (ISO) Information
3A8564C 7
Important Isocyanate (ISO) Information
Isocyanates (ISO) are catalysts used in two component materials.
Isocyanate Conditions
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
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.
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.

a. Close the bleed type air motor valve and the
elevator director valve. The ram will slowly
drop. See FIG. 4.
4. Engage the gun/valve trigger lock.
5. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
6. Engage the gun/valve trigger.
7. Open the fluid line drain valve and the pump bleed
valve (P). Have a container ready to catch the drain-
age.
8. Leave the pump bleed valve open until ready to
spray again. See FIG. 5.
If you suspect that the spray tip/nozzle or hose is
completely clogged, or that pressure has not been fully
relieved after following the steps above, very slowly
loosen the tip guard retaining nut, nozzle, or hose end
coupling and relieve pressure gradually, then loosen
completely. Now clear the tip/nozzle or hose.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.

Maintenance
Pump Lubrication
Frequency of greasing intervals is dependent on
material being pumped. As a basic schedule lubricate
pump with grease after 250 gallons of product (five
drums or fifty, five gallon pails) has been passed
through pump.
If the grease has become hardened, remove the seal
retainer (B) and remove the hardened materials or
grease. Shorten the intervals between greasing the
pump.
If the grease remains a clear and clean liquid the
intervals between greasing the pump can be extended.
Use Graco 0553-6 grease (138) or equivalent to
lubricate pump.
To grease the pump
1. Loosen M5 SHS EXT screw (102) two turns to
permit grease to circulate through pump correctly.
2. Attach grease gun to grease fitting (101) until fresh
grease is observed to come out grease relief hole
below the M5 SHS EXT screw (102). See FIG. 6.
