Warnings

Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama­tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:
Use equipment only in well ventilated area.
Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).
Keep work area free of debris, including solvent, rags and gasoline.
Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes are present.
Ground all equipment in the work area.
Use only grounded hoses.
Hold gun firmly to side of grounded pail when triggering into pail.
If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.
Keep a working fire extinguisher in the work area.
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
Do not point gun at anyone or at any part of the body.
Do not put your hand over the spray tip.
Do not stop or deflect leaks with your hand, body, glove, or rag.
Do not spray without tip guard and trigger guard installed.
Engage trigger lock when not spraying.
Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.
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.
Do not leave the work area while equipment is energized or under pressure. Turn off all equipment and follow the Pressure Relief Procedure in this manual 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.
Use equipment only for its intended purpose. Call your distributor for information.
Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
Do not kink or over bend hoses or use hoses to pull equipment.
Keep children and animals away from work area.
Comply with all applicable safety regulations.

Warnings
WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate fingers and other body parts.
Keep clear of moving parts.
Do not operate equipment with protective guards or covers removed.
Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.
Read MSDS’s to know the specific hazards of the fluids you are using.
Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
Always wear impervious gloves when spraying or cleaning equipment.
If this equipment is used with isocyanate material, see additional information on isocyanates in Isocy­anate Conditions Section of this manual.
BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe burns:
Do not touch hot fluid or equipment.
Wait until equipment/fluid has cooled completely.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:
Protective eyewear
Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
Hearing protection

Isocyanate Conditions

Isocyanate Conditions
Spraying 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

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
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.
), Part 206995.

Keep Components A and B Separate

Some materials may become self-igniting if applied too thickly. Read material manufacturer’s warnings and material MSDS.

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.
NOTICE
To prevent cross-contamination of the equipment’s wetted parts, never interchange component A (iso­cyanate) and component B (resin) parts.

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

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.

Pressure Relief Procedure

Pressure Relief Procedure
Trapped air can cause the pump to cycle unexpect­edly, which could result in serious injury from splash­ing or moving parts.
1. Select Park on Pump Control Switch if available, or turn off.
2. Turn off feed pumps.
3. Trigger gun to relieve pressure.
4. Close gun inlet valves.
5. Close fluid supply inlet valves.
6. Open all fluid drain valves in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to spray again.

Flushing

Flush equipment only in a well-ventilated area. Do not spray flammable fluids. Do not turn on heaters while flushing with flammable solvents.
Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts.
Flush out old fluid with new fluid, or flush out old fluid with a compatible solvent before introducing new fluid.
Use lowest possible pressure when flushing.
7. If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after follow­ing the steps above, VERY SLOWLY loosen tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Clear hose or tip obstruction.
