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

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

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 manufacturer’s warnings.

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

• Do not alter or modify equipment.

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

• For professional use only.

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

• Do not use hoses to pull equipment.

• Comply with all applicable safety regulations.

PRESSURIZED EQUIPMENT HAZARD

Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

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.

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 equip-

ment, 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.

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 lights on or off when flammable fumes are present.

• Ground equipment and conductive objects. 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 equip- ment until you identify and correct the problem.

Installation

Mounting the Pump

Mount the pump securely so that it cannot move during operation. Failure to do so could result in personal injury or equipment damage.

• Select a location that allows the operator easy access to the pump and air controls, sufficient room to change supply containers, and a secure mounting platform.

• If you are mounting the pump directly on the supply container, be sure it is positioned so the pump’s intake tube is no more than 1 in. (25 mm) from the bottom of the container. Mount the pump to the cover or other suitable mounting device.

To prevent damage to the pump, remove sediment from the bottom of the container before installing a pump in an existing container.

• Any pails used when flushing: Use only metal, grounded pails when flushing. Make firm metal-to-metal contact between a metal part of the dispensing valve and the pail. Use the lowest possible pressure.

To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the valve firmly to the side of a grounded metal pail, then trigger the valve.

To ground the pump, remove the ground screw (Z) and insert through the eye of the ring terminal at end of ground wire, (Y). Fasten the ground screw back onto the pump and tighten securely. Connect the other end of the ground wire to a true earth ground. See F a ground wire and clamp order Part No. 222011.

IG. 2. To order

Grounding

Proper grounding is essential to maintaining a safe system.

To reduce the risk of static sparking, ground the pump. Check local electrical codes for detailed grounding instructions for your area and equipment type. Be sure the following equipment is properly grounded:

• Pump: See F

• Air and fluid hoses: Use only electrically conductive hoses.

• Air compressor: Follow manufacturer’s recommendations.

• Dispensing valve: Obtain grounding through connection to a properly grounded fluid hose and pump.

• Fluid supply container: Follow your local code.

• Object being lubricated: Follow your local code.

Operation

See FIG. 1 to identify references shown in parentheses, i.e., (A).

This equipment stays pressurized until pressure is manually relieved. Read PRESSURIZED EQUIPMENT HAZARD warnings on page 2.

Maximum working pressure of all components in the system may not be the same. To reduce risk of overpressurizing any component, be sure you know the maximum working pressure of each component. Never exceed the maximum working pressure of the lowest rated component in the system. Overpressurizing any component can result in rupture, fire, explosion, property damage, and serious injury.

To determine the fluid output pressure using the air regulator reading, multiply the ratio of the pump by the air pressure shown on the regulator gauge. For example:

3:1 ratio x 100 psi air = 300 psi fluid output

Limit the air pressure to the pump so that no air line or fluid line component is overpressurized.

Pressure Relief Procedure

1. Close the pump air regulator (C) and the bleed-type master air valve (A), required in your system.

2. Hold a metal part of the dispensing valve (H) firmly to a grounded metal waste container, and trigger the valve to relieve fluid pressure.

3. Open the pump air regulator (C) slowly, just until the pump is running. When the pump is primed and all air has been pushed out of the lines, close the dispensing valve (H).

NOTE: When the pump is primed, and with sufficient air supplied, the pump starts when the dispensing valve (H) is opened, and shuts off when it is closed.

4. Adjust the air regulator (C) until you get sufficient flow from dispensing valve (H). Always run the pump at the lowest pressure necessary to get the desired results. Do not exceed the maximum working pressure of any component in the system.

CAUTION

Never allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly causing pump damage. It may also get very hot.

5. If your pump accelerates quickly or is running too fast, stop it immediately and check the fluid supply. If the supply container is empty and air has been pumped into the lines, prime the pump and lines with fluid, or flush it and leave it filled with a compatible solvent. Be sure to eliminate all air from the fluid lines.

6. Read and follow the instructions supplied with each component in your system.

7. If the pump will be unattended for any period of time, if there is an air supply interruption, or at the end of the work shift, shut off the system and always

relieve the pressure.

Starting and Adjusting the Pump

1. With the air regulator (C) closed, open the bleed-type master air valve (A).

2. Open the dispensing valve (H) into a grounded metal waste container, making firm metal-to-metal contact between the container and valve.
