WARNING

INJECTION HAZARD

Fluid

dispensed from the valve, leaks or ruptured components can inject fluid into your body and

cause extremely serious injury

, including the need for amputation. Fluid splashed in the eyes or on the

skin can also cause serious injury



Fluid injected into the skin might look like just a cut, but it is a serious injury

. Get immediate medi

cal attention.



Do not point the valve at anyone or at any part of the body



Do not put your hand or fingers over the spray nozzle.



Do not stop or deflect leaks with your hand, body

, glove or rag.



Do not “blow back” fluid; this is not an air spray system.



Always have the tip guard and the trigger guard on the gun/valve when dispensing.



Be sure the valve trigger safety operates before dispensing.



Component Description

This

equipment consists of two major components: the

air motor (1) and the displacement pump (100). See

Fig. 1 . The pump is an in-line design, which means

that the displacement pump screws directly into the

motor

, without the use of tie rods or couplers. The dis

placement pump can be placed directly in the fluid be

ing pumped.

The pump is available in three different lengths, based

on the size of the fluid container

. Refer to the front cov

er for available sizes. The pumps dif

fer only in length;

operation and packings are the same. All three pumps

use Model 235–887 Air Motor

Make sure the muf

fler (36) is securely installed in the

exhaust port (N) before you operate the pump. See

Fig. 1.

CAUTION

Never run the pump without the muf

fler installed.

the section

FIRE OR EXPLOSION

HAZARD

on page 4.

Ground all of this equipment:

Pump:

Use a ground wire and clamp as shown in

Fig. 2. Loosen the grounding lug locknut (W) and

washer (X). Insert one end of a 12 ga (1.5 mm

minimum ground wire (Y) into the slot in lug (Z) and

tighten the locknut securely

. Connect the other end

of the wire to a true earth ground. Order part num

Fluid hoses:

Use only grounded fluid hoses.

Air hoses:

Use only grounded air hoses.

Dispensing V

alve:

Obtain grounding through

connection to a properly grounded fluid hose and

pump.

Fluid supply container:

Follow your local code.

Air compressor:

Follow your local code.

o maintain grounding continuity when flushing or

relieving pressure

, hold a metal part of the spray

gun firmly to the side of a grounded

metal

pail, then

trigger the gun.

ensure easy operator access to the pump air

controls, sufficient room to change supply contain

ers, and a secure mounting platform.

If using a follow plate (K), remove the fluid contain

er cover

o prevent air from being trapped under

the follow plate, scoop grease from the center of

the container to the sides, to make the surface

WARNING

Maximum

reduce the risk of overpressurizing any part of your

system, be sure you know the maximum working

pressure rating of each component. Never exceed

the maximum working pressure of the lowest rated

component connected to a pump. Use the following

table to limit the air to the pump so that no air line

or fluid line component or accessory is overpres

surized.

Installation

WARNING

A bleed-type master air valve is required in your

system to help reduce the risk of serious injury

including splashing in the eyes or on the skin, and

injury from moving parts if you are adjusting or

repairing the pump.

The bleed-type master air valve relieves air trapped

between this valve and the pump after the air is

shut of

f. T

rapped air can cause the pump to cycle

unexpectedly

. Locate the valve close to the pump.

Install a bleed-type master air valve (B), to relieve

air trapped between the valve and the motor

. See

the

ARNING

above).

Install an air regulator (C), to control the pump

speed and pressure.

Install an air line filter (F) to remove harmful dirt

and moisture from the compressed air supply

Install a second bleed-type master air valve (G)

upstream from all other accessories, to isolate the

accessories for servicing.

Connect the fluid hose (L) to the dispense

valve (M). Use a gun holder (J) to hold the dis

pense valve when not in use.

For ease in connecting the air line to the pump,

use an air line quick disconnect (E) at the pump air

inlet.

Connect the air (D) and fluid hoses (L) to the pump

(A). Use only grounded fluid and air hoses. Be

sure all hoses are properly sized and pressure-

rated for your system.

NOTE:

Additional air line lubrication is not required to

extend the Eagle



grease pump air motor life. The air

motor is prelubed at the factory and should not require

additional lubrication between maintenance schedules.

No accessory air line lubricator should be installed.

Close the pump air regulator

Close the bleed-type master air valve (required in

If you suspect that the spray tip or hose is completely

clogged, or that pressure has not been fully relieved

after following the steps above,

pressure gradually

, then loosen completely; then clear

the tip or hose.

Flushing

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 solvent before using the pump.

WARNING

For your safety

, read the warning section
