Warnings

The following general warnings are related to the safe setup, use, grounding, maintenance, and repair of this equipment. Additional more specific warnings may be found throughout the text 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 equipment and conductive objects in work area. See Grounding instructions.

• 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 fire extinguisher in the work area.

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.

• Connect only to grounded power source.

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

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.

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.

Warning

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system com-

ponent. 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 manufacturer’s 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 and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or overbend hoses or use hoses to pull equipment.

• Comply with all applicable safety regulations.

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.

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.

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

RECOIL HAZARD

Gun may recoil when triggered and cause you to fall and be seriously injured if you are not standing securely.

2. Model 248842 Only: This model uses a remote mix

manifold, which is connected to the unit by at least 50 ft. (15 m) of individual fluid hoses. Refer to manuals 310794 and 310797 for typical setups.

All Other Models: The 50 ft. (15 m) fluid hose (W), static mixer (X), whip hose (Y), and gun (Z) come assembled. Note the order of connection.

CAUTION

Do not assemble static mixer (X) directly to fluid manifold. Install static mixer after first 50 ft. (15 m) of hose to ensure material is completely mixed. Spraying unmixed material could necessitate rework of part sprayed.

Flushing

There are times when you only want to flush the fluid manifold, such as:

• breaks in spraying

• overnight shutdown

• end of potlife

In this manual, that procedure is referred to as Fluid Manifold Flushing. You can flush the fluid manifold by connecting either a:

• solvent pump to the fluid manifold or

• hose and solvent siphon tube to pump A

Other times, you need to flush the entire system:

• first time material is loaded into equipment*

• color change

•servicing

• shutting down equipment for more than 24 hours

• putting equipment into storage

* Some Full System Flushing steps are not necessary for

initial flushing, as no material has been loaded into the system yet.

Fluid Manifold Flushing

Model 248842 Only: Follow the flushing procedure

in the Remote Manifold manual 310797.

Using Solvent Pump

1. Press Stop to turn off proportioner. Follow Pres-

sure Relief Procedure, page 10. Engage trigger

lock. Remove spray tip.

ti1949a

2. Close sampling valves and fluid shutoff valves A and

TI1948A

To flush the entire system, you first follow the Fluid Manifold Flushing procedure, at right, then the Full System Flushing procedure, page 16.

WARNING

Read warnings, pages 5-6.

• If your system includes heaters and heated hose, turn them off and allow to cool before flushing. Do not turn on heaters until fluid

lines are clear of solvent.

• Use the lowest possible pressure when flushing to avoid splashing.

• Before color change or shutdown for storage, flush at a higher flow rate and for a longer time.

• To only flush fluid manifold, see following procedure.

• A circulation setting is available. Consult your distributor. Refer to page 25.

3. Connect a shutoff valve (V) to the fluid manifold inlet

on the A side as shown below (valve shown closed). Connect solvent pump line to the shutoff valve. Turn on solvent pump and open solvent shutoff valve.

Mix and Integration Tests

Use the following tests to check for proper mix and integration.

Butterfly Test

WARNING

Follow Pressure Relief Procedure, page 10, before removing spray tip. Read warnings, page 5.

At low pressure, normal flow rate, and without a spray tip installed, dispense a 1/2” (12.7 mm) bead of material onto foil until multiple changeovers of each pump have occurred. Place a second sheet of foil over the first then peel it back and look for unmixed material (appears marble-like).

Curing Test

Spray a single continuous pattern on foil at typical pressure setting, flow rate, and tip size until multiple changeovers of each pump have occurred. Trigger and de-trigger at typical intervals for the application. Do not overlap or cross over your spray pattern.

Check curing at various time intervals, listed on the material data sheet. For example, check for dry to touch by running your finger along the test pattern’s entire length at the time listed on the data sheet.

Appearance Test

Spray material onto metal substrate. Look for variations in color, gloss, or texture that may indicate improperly catalyzed material.
