Warnings

3A9247A 3

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 symbols refer to procedure-specific risks.

When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings.

Product-specific hazard symbols and warnings not covered in this section may appear throughout the body 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. Paint or

solvent flowing through the equipment can cause static sparking. 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 sparking).

• Ground all equipment in the work area. See Grounding instructions.

• Never spray or flush solvent at high pressure.

• 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.

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they

are anti-static or conductive.

•Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment

until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

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.

• Engage trigger lock when not dispensing.

• 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.

Warnings

4 3A9247A

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 Specifications in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Technical

Specifications in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For

complete information about your material, request Safety Data Sheets (SDSs) 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. Alterations or modifications may void agency approvals and

create safety hazards.

• Make sure all equipment is rated and approved for the environment in which you are using it.

• 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.

MOVING PARTS HAZARD

Moving parts can pinch, cut or amputate fingers and other body parts.

• Keep clear of moving parts.

• Do not operate equipment with protective guards or covers removed.

• Equipment can start without warning. Before checking, moving, or servicing equipment, follow

the Pressure Relief Procedure and disconnect all power sources.

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 Safety Data Sheets (SDSs) 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

Wear appropriate protective equipment when in the work area to help prevent serious injury,

including eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment

includes but is not limited to:

• Protective eyewear, and hearing protection.

• Respirators, protective clothing, and gloves as recommended by the fluid and solvent

manufacturer.

Pump Assembly

1. Assemble Coupling Adapter (H) to the Motor (F).

2. Assemble Tie Rod with Extension (L) to the Motor

(F).

3. Assemble Displacement Pump (G) to Tie Rod with

Extension (L) and hand-tighten the Hex Nuts (N).

4. Assemble Coupling Collars (K) and Coupling Nut (J)

to Coupling Adapter (H).

5. Assemble Hex Nuts (N) to Tie Rod with Extension

(L).

NOTICE

Use the 3 lift rings (eyebolts), attached to the

mounting plate, for lifting and moving the motor into

place for installation. Moving the motor by any other

means could damage the pump assembly.

Pressure Relief Procedure

3A9247A 7

Pressure Relief Procedure

1. Shut off pump by turning off hydraulic line supply

shutoff valve.

2. Open recirculation valve and trigger auto gun(s) to

relieve pressure.

3. Trigger each auto gun for at least 3 seconds.

This equipment stays pressurized until pressure is

manually relieved. To help prevent serious injury from

pressurized fluid, such as skin injection, splashing

fluid and moving parts, follow the Pressure Relief

Procedure when you stop spraying and before

cleaning, checking, or servicing the equipment.

Maintenance

8 3A9247A

Maintenance

Packing Nut / Wet-Cup

1. Fill the Packing Nut/Wet Cup (P) 1/3 full with Graco

Throat Seal Liquid (TSL).

2. Use the supplied Packing Nut Wrench (Q) to adjust

the packing nut weekly so that it is just snug. Do

NOT over-tighten.

Flush the Pumping System

The pump is tested with lightweight oil, which is left in

to protect the pump parts. If the fluid you are using may

be contaminated by the oil, flush it out with a

compatible flush material before using the pump.

• Flush at the lowest pressure possible. Check

connections for leaks and tighten as necessary.

• Flush with a fluid that is compatible with the fluid

being dispensed and the equipment wetted parts.

1. Perform the Pressure Relief Procedure, page 7.

2. Set pump to lowest possible fluid pressure, and

then start the pump.

3. Dispense fluid into a grounded metal pail.

Disconnect the Displacement

Pump

1. Flush the pump, see Flush the Pumping System,

page 8.

2. Stop the pump at the bottom of its stroke.

3. Perform the Pressure Relief Procedure, page 7.

4. Disconnect the hydraulic hose. Plug all hydraulic

hoses immediately to prevent the contamination of

the hydraulic system. Hold the fluid outlet fitting

with a wrench to keep it from being loosened while

you disconnect the fluid hose.

5. Disconnect the Displacement Pump (G) from the

Motor (F) as follows. Make sure to note the relative

position of the pump fluid outlet to the hydraulic

inlet of the motor due to orientation restrictions on

the system. If the motor does not require servicing,

leave it attached to its mounting.

6. Using adjustable wrenches to unscrew the

Coupling Nut (J) from the Coupling Adapter (H).

Remove the Coupling Collars (K). Take care not to

lose or drop the collars. See page 5.

7. Hold the Tie Rod (L) flats with a wrench to keep the

rods from turning. Unscrew the Hex Nuts (N) from

the Tie Rods extensions (L). Carefully remove the

Displacement Pump (G) from the Motor (F). See

page 5.

Storage Maintenance

Replace leather packings every five years.

Lifetime Service Maintenance

Replace leather packings every five years or less based

on use.

Use at least two people when lifting, moving, or

disconnecting the pump. If disconnecting the

displacement pump from a motor which is still

mounted (for example, on a wall bracket), be sure to

support the displacement pump while it is being

disconnected. Failure to do so may result in the pump

falling and causing injury or damage to property.
