WARNING
WARNINGWARNINGWARNING
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:
• Do not spray flammable or combustible materials near an open flame or sources of ignition such as cigarettes, motors, and electrical equipment.
• Paint or solvent flowing through the equipment is able to result in static electricity. Static electricity creates a risk of fire or explosion in the presence of paint or solvent fumes. All parts of the spray system, including the pump, hose assembly, spray gun, and objects in and around the spray area shall be properly grounded to protect against static discharge and sparks. Use Graco conductive or grounded high-pressure airless paint sprayer hoses.
• Do not clean with materials having flash points lower than 70° F (21° C). Use water-based material or mineral spirits-type material only. For complete information about your fluid, request the MSDS from the fluid distributor or retailer.
• Verify that all containers and collection systems are grounded to prevent static discharge.
SKIN INJECTION HAZARD
High-pressure fluid from dispensing device, 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 dispensing device at anyone or at any part of the body.
• Do not put your hand over the fluid outlet.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace worn or damaged parts immediately.

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 Dat a in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about your material, request MSDS from distributor or retailer.
• Do not leave the work area while equipment is energized or under pressure. Turn off all equipment and follow the Pressure Relief Procedure 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.
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 MSDSs 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.

Installation

Installation
Accessories are available from Graco. Be sure all accessories are properly sized to withstand the pres­sures in the system.

Connect the Air Lines

Connect Fluid Lines

ti16343a
Connect a grounded fluid line from the pump to the fluid adapter of the paint spray gun. You should install a fluid pressure regulator to control fluid pressure to the paint spray gun. The regulator enables you to control fluid pressure more accurately than by regulating hydraulic pressure to the pump.
Install a fluid filter to remove particles and sediment which may clog the tip.
Install a manual ball valve to shut off fluid flow to spray gun.
ti16776a
Single-Acting Gun
ti16342a
Double-Acting Gun
Clean all lines and connections of dirt, burrs, etc. and blow them out with clean air before connecting them to the system. Install an air filter in the air supply line to remove harmful dirt and moisture from the compressed air.

Grounding

Proper grounding is essential to maintaining a safe sys­tem.
To reduce the risk of static sparking, ground the pump, paint spray gun, and all other system equipment.
1. Pump: Use a ground wire and clamp.
2. Air compressors and hydraulic power supplies: Follow manufacturer’s recommendations.
3. Air and fluid hoses connected to the pump: Use only grounded hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity.
4. Dispensing valve: Obtain grounding through con­nection to a properly grounded fluid hose and pump.
5. Fluid supply container: According to local code.
6. All solvent pails used when flushing: Ground according to local code. Use only metal pails, which are conductive. Do not place the pail on a non con­ductive surface, such as paper or cardboard, which interrupts the grounding continuity.
