Important Two-Component Material Information
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.
Important Two-Component Material Information
Isocyanate Conditions Keep Components A and B
Separate
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
Cross-contamination can result in cured material in fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination of the equipment’s wetted parts, never interchange component A (isocyanate) and component B (resin) parts.
Some materials may become self-igniting if applied too thickly. Read material manufacturer’s warnings and material MSDS.
313536L
Important Two-Component Material Information
Moisture Sensitivity of
Isocyanates
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.
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.
• Keep the ISO lube pump reservoir (if installed) 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 lubricate threaded parts with ISO pump oil or grease when reassembling.
Changing Materials
• 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.
• 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.
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.
313536L 7

Grounding
Grounding
The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.
Pump: use ground wire and clamp (supplied). Connect ground clamp to a true earth ground.
Gun: ground through connection to a properly grounded fluid hose and pump.
Fluid supply container: follow local code.
Solvent pails used when flushing: follow 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.
Maintain grounding continuity: When flushing or relieving pressure, hold metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun.
313536L
Trigger Lock
Trigger Lock
Verify that the trigger lock is engaged whenever you stop pouring to avoid accidental triggering. Check daily for chemical build-up on trigger, trigger lock, and trigger lock spring that can prevent proper trigger lock function.
Engage
To engage the trigger lock, release the trigger. The trigger lock is spring loaded and automatically engages when the gun trigger is released.
To engage the trigger lock, press the trigger lock down.

Hydraulic pressure extends the piston rod to the circulation position. Material enters the material pressure line and is sent to the material return line.
When the piston rod is extended to this position, it removes gelled material from the nose assembly.
Hydraulic pressure retracts the piston rod to the dispense position. Material enters the A and B material pressure lines and mixes in the mixing chamber.
When the piston rod is in this position, it blocks material flow from entering the material return line.
