Operation

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:

D

are instructed to relieve the pressure,

D

stop spraying,

D

check or service any of the system equipment,

D

or install or clean the spray tips.

1. Lock the spray gun trigger safety.
2. Shut off the air to the pump.
3. Close the bleed-type master air valve (required in

your system).

4. Unlock the gun trigger safety.
5. Hold a metal part of the gun firmly to the side of a

grounded metal pail, and trigger the gun to relieve

pressure.

6. Lock the spray gun trigger safety.
7. Open the drain valve (required in your system),

having a container ready to catch the drainage.

8. Leave the drain valve open until you are ready to

spray again.

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, very slowly loosen the

tip guard retaining nut or hose end coupling and relieve

pressure gradually, then loosen completely. Now clear

the tip or hose.

WARNING

Moving parts can pinch or amputate your fingers or

other body parts. When air is supplied to the motor,

the air motor piston (located behind the air motor

plates) moves. See Fig. 2. Therefore, never oper-

ate the pump with the air motor plates removed.

Flush the Pump Before Using

The pump is tested with lightweight motor 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. If the

pump is being used to supply a circulating system,

allow the solvent to circulate until the pump is thor-

oughly flushed.

WARNING

FIRE AND EXPLOSION HAZARD

For your safety, read the section

FIRE

AND EXPLOSION HAZARD

on page 4

before flushing and follow all the recom-

mendations given there.
