WARNING

INJECTION HAZARD

Spray from the gun/valve, hose leaks, or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury.

D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medi-

cal attention.

D Do not point the gun/valve at anyone or at any part of the body.

D Do not put your hand or fingers over the spray tip/nozzle.

D Do not stop or deflect leaks with your hand, body, glove or rag.

D Do not “blow back” fluid; this is not an air spray system.

D Always have the tip guard and the trigger guard on the gun when spraying.

D Check the gun diffuser operation weekly. Refer to the gun manual.

D Be sure the gun/valve trigger safety operates before spraying/dispensing.

D Lock the gun/valve trigger safety when you stop spraying/dispensing.

D Follow the Pressure Relief Procedure on page 8 whenever you: are instructed to relieve pres-

sure; stop spraying/dispensing; clean, check, or service the equipment; and install or clean the spray tip/nozzle.

D Tighten all fluid connections before operating the equipment.

D Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.

Permanently coupled hoses cannot be repaired; replace the entire hose.

D Use only Graco approved hoses. Do not remove any spring guard that is used to help protect the

hose from rupture caused by kinks or bends near the couplings.

MOVING PARTS HAZARD

Moving parts, such as the air motor piston, can pinch or amputate your fingers.

D Keep clear of all moving parts when starting or operating the pump.

D Before servicing the equipment, follow the Pressure Relief Procedure on page 8 to prevent the

equipment from starting unexpectedly.

Installation

NOTES:

D Reference numbers and letters in parentheses in

the text refer to the callouts in the figures and drawings.

D Always use Genuine Graco Parts and Accessories,

available from your Graco distributor. If you supply your own accessories, be sure they are adequately sized and pressure-rated to meet the system’s requirements.

D Fig. 2 is only a guide for selecting and installing

system components and accessories. Contact your Graco distributor for assistance in designing a system to suit your particular needs.

Prepare the Operator

All persons who operate the equipment must be trained in the safe, efficient operation of all system components as well as the proper handling of all fluids. All operators must thoroughly read all instruction manuals, tags, and labels before operating the equipment.

Prepare the Site

Ensure that you have an adequate compressed air supply. Refer to the performance chart on page 15 to find the air consumption of your pump.

Keep the site clear of any obstacles or debris that could interfere with the operator’s movement.

D Pump: Use a ground wire and clamp. See Fig.1.

Loosen the grounding lug locknut (W) and washer (X). Insert one end of a 12 ga (1.5 mm@) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. Connect the other end of the wire to a true earth ground. For a ground wire and clamp, order Part No. 237569.

Fig. 1

D Air and fluid hoses: Use only electrically conductive

hoses with 150 m (500 ft) maximum combined hose length to ensure grounding continuity.

D Air compressor: Follow manufacturer’s

recommendations.

D Spray gun or dispensing valve: Connect to a

properly grounded fluid hose and pump.

D Object being sprayed: Follow your local code.

Have a grounded, metal pail available for use when flushing the system.

Mounting the Pump

Screw the bung adapter (B) tightly into the drum bung hole and tighten the thumbscrew to hold the pump about 13 mm (0.5 in.) off the bottom of the drum. Loosen the drum vent plug to prevent forming a vacuum. The pump dimensions are shown on page 13.

Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the system as explained below. Also read the section FIRE AND EXPLOSION HAZARD on page 4.

D Fluid supply container: Follow your local code.

D Solvent pails used when flushing: Follow your local

code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.

D To maintain proper grounding continuity when

flushing or relieving pressure, always hold the metal

part of the spray gun/dispense valve firmly to the side of a grounded metal pail, then trigger the gun/valve.
