Installation

NOTE: Reference numbers and letters in parentheses

in the text refer to the callouts in the figures and the

parts drawing.

NOTE: Always use Genuine Graco Parts and Acces-

sories, available from your Graco distributor.

Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the

system as explained below. Also read

the section FIRE OR EXPLOSION HAZ-

ARD on page 4.

DPump: Use a ground wire and clamp as shown

below.

Fig. 1 TI1052

DAir and fluid hoses: Use only electrically conductive

hoses.

DAir compressor: Follow manufacturer’s recommen-

dations.

DDispensing valve: Ground through connection to a

properly grounded fluid hose and pump.

DObject being dispensed to: Follow your local code.

DSolvent pails used when flushing: Follow your local

code. Use only metal pails, which are conductive,

placed on a grounded surface. Do not place the pail

on a nonconductive surface, such as paper or

cardboard, which interrupts the grounding continu-

ity.

DTo maintain grounding continuity when flushing or

relieving pressure, hold a metal part of the dispens-

ing gun firmly to the side of a grounded metal pail,

then trigger the gun.

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 Fig. 1.

To order a ground wire and clamp, order Part No.

222011.

Mounting the Pump

WARNING

Mount the pump securely so that it cannot move

around during operation. Failure to do so could

result in personal injury or equipment damage.

DSelect a convenient location for the equipment to

ensure easy operator access to the pump air

controls, sufficient room to change supply contain-

ers, and a secure mounting platform.

DIf you are mounting the pump directly on the supply

tank, position the pump so its intake valve 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.

6 306674U

Installation

Mount the pump to suit the type of installation planned.

Very heavy lubricants may require an inductor plate.

See page 18 for the mounting hole layout and dimen-

sions

Install the air line accessories in the approximate order

shown in the Typical Installation. Install a bleed-type

master air valve (B) within easy reach of the pump,

upstream from the air regulator. Install an air filter (C)

to remove harmful dirt and moisture from your com-

pressed air supply. For automatic air motor lubrication,

install an air line oiler (D) close to the pump air inlet.

Install an air regulator (E) to control pump speed.

WARNING

A bleed-type master air valve (B) is required to

shut off and relieve air pressure that may be

trapped in the air motor. Trapped air could cause

the pump to cycle unexpectedly and cause serious

bodily injury, including amputation.

Be sure the air hose is properly sized to deliver an

adequate supply of air to the motor. Refer to the

Technical Data on page 19.

Connect a dispensing hose to the 3/8 npt(f) pump

outlet. Install an appropriate gun or dispensing valve to

the hose.

Ground the pump as explained on page 5.

Operation

WARNING

DThis pump is designed to be used ONLY in

pumping non-corrosive and non-abrasive lubri-

cants and greases. Any other use of this pump

can cause unsafe operating conditions and

result in component rupture, fire, or explosion,

which can can cause serious bodily injury,

including injection.

DMoving parts can pinch or amputate your fin-

gers or other body parts. When the pump is

operating, the priming piston (located at the

pump intake) and the air motor piston (located

behind the air motor plates) move. NEVER

Operate the pump with the air motor plates

removed, and keep your fingers and hands

away from the priming piston.

Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD

Fluid under high pressure can be in-

jected through the skin and cause

serious injury. To reduce the risk of an

injury from injection, splashing fluid, or moving

parts, follow the Pressure Relief Procedure

whenever you

DAre instructed to relieve the pressure

DStop dispensing

DCheck or service any of the system equipment

DInstall or clean the dispensing nozzles

1. Close the air regulators.

2. Close the supply pump’s bleed-type master air

valve (required in this system).

3. Open the dispensing valve until pressure is fully

relieved.

If you suspect that the dispensing valve, extension, or

grease fitting coupler is clogged, or that pressure has

not been fully relieved after following the steps above,

VERY SLOWLY loosen the coupler or hose end cou-

pling and relieve pressure gradually, then loosen

completely, then clear the clog.

Startup and Adjustment

Open the bleed-type master air valve. Open the dis-

pensing valve, and slowly open the air regulator until

the pump is running smoothly. After all the air is

purged, close the dispensing valve. The pump will

start and stop as the valve is opened and closed.

CAUTION

Never allow the pump to run dry of the fluid being

pumped. A dry pump quickly accelerates to a high

speed and may damage itself. If your pump acceler-

ates 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 the pump and

leave it filled with a compatible solvent. Be sure to

eliminate all air from the fluid system.

Use the air regulator (E) to control the pump speed

and fluid pressure. See Fig. 2. Always use the lowest

pressure necessary to obtain the desired results.

When you are finished using the pump for the day,

always follow the Pressure Relief Procedure at left.

Maintenance

The Accessory air line oiler (D) provides automatic air

motor lubrication. For daily manual lubrication, discon-

nect the air hose, place about 15 drops of light ma-

chine oil in the air inlet, reconnect the hose, and turn

on the air supply to blow oil into the motor.
