WARNINGS

High Pressure Spray Can Cause Serious Injury. For Professional Use Only.

Observe All Warnings. Read and understand all instruction manuals before operating equipment.

FLUID INJECTION HAZARD

General Safety

This equipment generates very high fluid pressure.

Spray from the gun, leaks or ruptured components

can inject fluid through your skin and into your body

and cause extremely serious injury, including the

need for amputation. Also, fluid injected or splashed

into the eyes or on the skin can cause serious dam-

age.

Never point the spray gun at anyone or at any part of

the body. Never put hand or fingers over the spray tip.

Never try to stop or deflect leaks with your hand or body.

Never try to “blow back” paint; this is not an air spray

gun.

Always follow the Pressure Relief Procedure, at

right, before cleaning or removing the spray tip or

servicing any system equipment.

Check operation of all equipment safety devices

before each use.

Medical Alert - Airless Spray Wounds

If any fluid appears to penetrate your skin, get emer-

gency medical care at once. Do not treat as a sim-

ple cut. Tell the doctor exactly what fluid was injected.

NOTE TO PHYSICIAN: Injection into the skin is a

traumatic injury. It is important to treat the injury

surgically as soon as possible. Do not delay treat-

ment to research toxicity. Toxicity is a concern with

some exotic coatings injected directly into the blood

stream. Consultation with a plastic surgeon or

reconstructive hand surgeon may be advisable.

Spray Gun Safety Devices

Be sure all gun safety devices are operating properly

before each use. Do not remove or modify any part of

the gun; this can cause a malfunction and result in

serious injury.

Safefy Latch

Whenever you stop spraying, even for a moment,

always set the gun safety latch in the closed or

“on safe” position, making the gun inoperative. See

Fig. 3, page 8. Failure to set the safety latch can result

in accidental triggering of the gun.

Diffuser

The gun diffuser breaks up spray and reduces the

risk of fluid injection when the tip is not installed.

Check diffuser operation regularly. Follow the Pres-

sure Relief Procedure, below, then remove the spray

tip. Aim the gun into a grounded metal pail, holding

the gun firmly to the pail. Using the lowest possible

pressure, trigger the gun. If the fluid emitted is not

diffused into an irregular stream, replace the diffuser

immediately.

Spray Tip Safety

Use extreme caution when cleaning or changing

spray tips. If the spray tip clogs while spraying,

engage the gun safety latch immediately. Always fol-

low the Pressure Relief Procedure, below, and then

remove the spray tip to clean it,

Never wipe off build-up around the spray tip or air cap

until pressure is fully relieved and the gun safety latch

is engaged.

Pressure Relief Procedure

To reduce the risk of serious injury, including fluid

injection, splashing in the eyes or on skin, or injury

from moving parts, always follow this procedure

whenever pump is shut off, when checking or servic-

ing any part of system, when installing or changing

spray tips and whenever you stop spraying.

Engage the spray gun safety latch.

Shut off the power to the pump.

Close the bleed-type master air valve (required in

system).

Disengage the gun safety latch.

Hold a metal part of gun firmly to the side of a

grounded metal container and trigger the gun to

relieve fluid pressure.

Engage the gun safety latch again.

Open pump drain valve (required in system)to

help relieve fluid pressure in the displacement

pump. In addition, open the drain valve con-

nected to the fluid pressure gauge (in a system

with fluid regulation) to help relieve fluid pressure

in the hose and gun. Triggering the gun to relieve

pressure may not be sufficient. Have a container

ready to catch the drainage.

Leave drain valve(s) 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

hose end coupling and relieve pressure gradually,

then loosen completely. Now clear the tip or hose

obstruction.
