Warnings

Warning

ELECTRIC SHOCK HAZARD

Improper grounding, setup, or usage of the system can cause electric shock.

•Turn off and disconnect power at main switch before disconnecting any cables and before servicing equipment.

•All electrical wiring must be done by a qualified electrician and comply with all local codes and regulations.

•Connect only to grounded power source.

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.

•Engage trigger lock when not spraying.

•Follow Pressure Relief Procedure on page 5 if the nozzle clogs and before cleaning, checking or servicing equipment.

TOXIC FLUID HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on the 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.

EQUIPMENT MISUSE HAZARD

Equipment misuse can cause death or serious injury.

•Do not exceed maximum working pressure or temperature rating of lowest rated system component. See Technical Data 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 manufacturers warnings.

•Check equipment daily. Repair or replace worn or damaged parts immediately.

•Do not alter or modify equipment.

•For professional use only.

•Use equipment only for its intended purpose. Call your Graco distributor for information.

•Route hoses away from traffic areas, sharp edges, moving parts and hot surfaces.

•Do not use hoses to pull equipment.

Grounding and Electrical Requirements

The following are minimum requirements for a basic dispensing system. Your system may include other equipment or objects that must be grounded. Check your local electrical code for detailed grounding instructions for your area and type of equipment.

To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of spray gun firmly to side of a grounded metal pail. Then trigger spray gun.

1.Pump: connect a ground wire and clamp to a true earth ground as shown in pump manual.

2.Applicator: ground through motor cable assembly.

3.Fluid and air hoses: only use electrically conductive material and air hoses.

4.Dispense gun: ground through connection of hose or cable.

5.Air compressor: follow manufacturer’s recommendations.

6.Object being sprayed: refer to local code.

7.Fluid supply container: refer to local code.

8.Solvent pails used for flushing: refer to local code.

Installation

Inspect flow gun for shipping damage. If damage is found notify the carrier immediately.

If material hose will be suspended by a hanger or tool balancer, route hose through the suspension device before securing each end of material hose.

1.Connect flow gun to any standard Graco hose assembly.

2.Connect the opposite end of the heated hose assembly to any fluid supply system. See Model table, page 2 for maximum fluid working pressure for your gun model.

3.Tighten fluid connections.

4.Before operating gun, squeeze and release trigger a few cycles. Observe action of cartridge assembly.

Pressure Relief Procedure

To help prevent injuries, follow this procedure when you shut off the flow gun and before checking or adjusting any part of gun.

1.Shut off air to pump.

2.Close bleed-type master air valve (required in your system).

3.Hold metal part of spray gun firmly to side of grounded metal pail. Trigger gun to relieve pressure.

ti3795a

4.Open drain valve and/or pump bleeder valve having a container ready to catch the drainage.

5.Leave drain valve open until you are ready to spray/dispense again.

If you suspect the tip/nozzle or hose is completely clogged or that pressure has not been fully relieved after following the above steps, VERY SLOWLY loosen the retaining nut or hose end coupling to relieve pressure gradually. Then loosen it completely. Clear tip/nozzle or hose.

Trigger Lock

Always engage trigger lock when you stop dispensing to prevent gun from being triggered accidentally by hand or if dropped or bumped.

To engage trigger lock, release trigger and rotate lock downward. See Fig. 1.

Do not try to force trigger valve open with trigger lock engaged. This could result in component fail-

ure.
