Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-

tion 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

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 all equipment in the 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 working fire extinguisher in the work area.

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.

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 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. For complete information

about your material, request MSDS forms from distributor or retailer.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu-

facturer’s replacement parts only.

• Do not alter or modify equipment.

• 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.

Warnings

8311828H

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.

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.

• Always wear impervious gloves when spraying or cleaning equipment.

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

WARNING

Installation

311828H 9

Installation

Grounding

The equipment must be grounded. Grounding reduces

the risk of static and electric shock by providing an

escape wire for the electrical current due to static build

up or in the event of a short circuit.

Pump: Use the ground screw (GS) and lockwasher on

the motor to attach a 244524 ground wire (Y). Tighten

the screw securely. Connect the other end of the ground

wire to a true earth ground.

Air and fluid hoses: use only electrically conductive

hoses.

Air compressor or hydraulic power supply: follow

manufacturer’s recommendations.

Spray gun: ground through connection to a properly

grounded fluid hose and pump.

Fluid supply container: follow local code.

Object being sprayed: follow local code.

Solvent pails used when flushing: follow local code.

Use only conductive metal pails, placed on a grounded

surface. Do not place the pail on a nonconductive sur-

face, such as paper or cardboard, which interrupts

grounding continuity.

To maintain grounding continuity when flushing or

relieving pressure: hold metal part of the spray gun

firmly to the side of a grounded metal pail, then trigger

the gun.

Flush Before Using Equipment

The equipment was tested with lightweight oil, which is

left in the fluid passages to protect parts. To avoid con-

taminating your fluid with oil, flush the equipment with a

compatible solvent before using the equipment. See

Flushing, page 15.

Mounting Accessories

See Dimensions, page 24 and Mounting Hole Lay-

outs, page 25.

Hoses

See F

IG

. 1 and F

IG

. 2. Be sure all hoses are properly

sized and pressure-rated for your system. Use only

electrically conductive hoses. Fluid hoses must have

spring guards on both ends. Use a whip hose (P) and a

swivel (R) between the main fluid hose (N) and the

gun/valve (S) to allow freer gun/valve movement.

• Use a minimum 13 mm (1/2 in.) ID supply line (C),

and a minimum 22 mm (7/8 in.) ID return line (D).

The motor has a 3/4 npt(f) hydraulic oil supply fit-

ting, and a 1 in. npt(f) hydraulic oil return fitting.

•Supply line shutoff valve (U) isolates the pump for

service.

•Fluid pressure gauge (F) monitors hydraulic oil

pressure to the motor to avoid overpressurizing the

motor or displacement pump.

•Pressure- and temperature-compensated flow

control valve (G) prevents the motor from running

too fast and possibly damaging itself.

•Pressure reducing valve (H) with a drain line (E)

runs directly to the hydraulic return line (D).

•Accumulator (J) reduces the hammering effect

caused by the motor reversing direction.

•Return line shutoff valve (V) isolates the pump for

service.

• Be sure your hydraulic power supply is equipped

with a suction filter to the hydraulic pump and a sys-

tem return line filter (W) of 10 micron size.

• Connect a 6 mm (1/4 in.) ID drain line (K) to the

barbed fitting on the drip pan, and place the free end

in a container to collect the drainage.

Operation

311828H 13

Operation

Pressure Relief Procedure

1. Engage trigger lock.

2. Shutoff the pump:

a.

For air-powered pumps,

close the bleed-type

master air valve.

b.

For hydraulic-powered pumps,

close the supply

line shutoff valve (U) first, then close the return

line shutoff valve (V).

3. Disengage the trigger lock.

4. Hold a metal part of the gun firmly to a grounded

metal pail. Trigger the gun to relieve pressure.

5. Engage the trigger lock.

6. Open all fluid drain valves in the system, having a

waste container ready to catch drainage. Leave

drain valve(s) open until you are ready to spray

again.

7. If you suspect the spray tip or hose is clogged or

that pressure has not been fully relieved after follow-

ing the steps above, VERY SLOWLY loosen tip

guard retaining nut or hose end coupling to relieve

pressure gradually, then loosen completely. Clear

hose or tip obstruction.

Trigger Lock

Always engage the trigger lock when you stop spraying

to prevent the gun from being triggered accidentally by

hand or if dropped or bumped.

Trapped air can cause the pump to cycle unexpectedly,

which could result in serious injury from splashing or

moving parts.

Operation

14 311828H

Startup

1. Connect the suction kit (T) to the pump's fluid inlet,

and place the tube into the fluid supply.

2. Prepare the pump’s power source:

a.

For air-powered pumps,

close the air regulator

(F). Open the pump's bleed-type master air

valve (E).

b.

For hydraulic-powered pumps,

check the

hydraulic fluid level before each use, and add

fluid as necessary. Close the supply line shutoff

valve (U) and the return line shutoff valve (V).

Start the hydraulic power supply.

3. Hold a metal part of the gun (S) firmly to the side of

a grounded metal pail and hold the trigger open.

4. Start the pump:

a.

For air-powered pumps,

slowly open the air reg-

ulator until the pump starts.

b.

For hydraulic-powered pumps,

open the return

line shutoff valve (V) first, then slowly open the

supply line shutoff valve (U).

5. Cycle the pump slowly until all air is pushed out and

the pump and hoses are fully primed. Release the

gun trigger and lock the trigger safety latch. The

pump should stall against pressure when the trigger

is released.

6. With the pump and lines primed, and with adequate

air or hydraulic pressure and volume supplied, the

pump will start and stop as the gun is opened and

closed. In a circulating system, the pump will speed

up or slow down on demand, until the air or hydrau-

lic supply is shut off.

7. Always use the lowest air or hydraulic pressure nec-

essary to get the desired results. Higher pressures

cause premature tip/nozzle and pump wear.

a.

For air-powered pumps,

use the air regulator (F)

to control the pump speed and fluid pressure.

b.

For hydraulic-powered pumps,

use the fluid

pressure gauge (F) and flow control valve (G) to

control the pump speed and the fluid pressure.

8. Never allow the pump to run dry of the fluid being

pumped. A dry pump will quickly accelerate to a

high speed, possibly damaging itself.

NOTE: 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, refill the container and prime the pump

and the lines with fluid, or flush and leave it filled with a

compatible solvent. Be sure to eliminate all air from the

fluid system.

Shutdown

Relieve the pressure, page 13. Stop the pump at the

bottom of its stroke to prevent fluid from drying on the

exposed displacement rod and damaging the throat

packings.

Maintenance

311828H 15

Maintenance

Preventive Maintenance

Schedule

The operating conditions of your particular system

determine how often maintenance is required. Establish

a preventive maintenance schedule by recording when

and what kind of maintenance is needed, and then

determine a regular schedule for checking your system.

Wet-Cups

Check the wet-cup daily. Keep the wet-cup 1/3 filled with

Graco Throat Seal Liquid (TSL

™

) or compatible solvent.

Flushing

1. Follow Pressure Relief Procedure, page 13.

2. Remove spray tip and soak in solvent.

3. Place siphon tube in grounded metal pail containing

cleaning fluid.

4. Set pump to lowest possible fluid pressure, and start

pump.

5. Hold a metal part of the gun firmly to a grounded

metal pail. Trigger the gun until clean solvent dis-

penses.

6. Remove gun from hose. See gun manual to further

clean gun.

7. Follow Pressure Relief Procedure, page 13, and

remove fluid filter and soak in solvent. Replace filter

cap.

Corrosion Protection

Always flush the pump before the fluid dries on the dis-

placement rod. Never leave water or water-based fluid

in the pump overnight. First, flush with water or a com-

patible solvent, then with mineral spirits. Relieve the

pressure, but leave the mineral spirits in the pump to

protect the parts from corrosion.

Hydraulic Systems

Carefully follow the manufacturer's recommendations

on reservoir and filter cleaning, and periodic changes of

hydraulic fluid. Use only Graco-approved hydraulic oil.

Order Part No. 169236, 5 gal. (19 liter) or 207428, 1 gal.

(3.8 liter). Do not substitute a lower grade oil or one with

a lower flash point.

• Flush before changing colors, before fluid can

dry in the equipment, at the end of the day,

before storing, and before repairing equipment.

• Flush at the lowest pressure possible. Check

connectors for leaks and tighten as necessary.

• Flush with a fluid that is compatible with the

fluid being dispensed and the equipment wetted

parts.

NOTICE

Keep the hydraulic supply system absolutely clean at

all times. Blow out hydraulic lines with air and flush

thoroughly with solvent before connecting to the

hydraulic motor, to avoid introducing harmful contami-

nants into the motor. Plug the hydraulic lines immedi-

ately when they are disconnected.

Do not exceed 37.8 liter/min (10 gpm) hydraulic oil

volume to the motor, to avoid stalling the pump.

Do not exceed 54°C (130°F) hydraulic oil tempera-

ture.

Troubleshooting

16 311828H

Troubleshooting

1. Relieve the pressure, page 13.

2. Check all possible causes and problems before dis-

assembling the pump.

* To determine if the fluid hose or gun is obstructed, relieve the pressure, page 13. Disconnect the fluid hose and

place a container at the pump fluid outlet to catch any fluid. Turn on the air/hydraulic power just enough to start

the pump. If the pump starts, the obstruction is in the fluid hose or gun.

Fluid Outlet Pressure

To find fluid outlet pressure (MPa/bar/psi) at a specific flow

(lpm/gpm) and operating pressure (A/B/C):

1. Locate desired flow at bottom of chart.

2. Follow vertical line up to intersection with selected operat-

ing pressure curve (solid line). Follow left to scale to read

fluid outlet pressure.

Pump Air or Hydraulic Oil Consumption

To find air or hydraulic oil consumption at a specific flow

(lpm/gpm) and operating pressure (A/B/C):

1. Locate desired flow at bottom of chart.

2. Follow vertical line up to intersection with selected operat-

ing pressure curve (dashed line). Follow left to scale to

read air or oil consumption.
