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 bodily injury, including the need for amputation. Also,
fluid injected or splashed into the eyes can cause serious
damage.

NEVER point the spray gun or dispensing valve at anyone or at
any part of the body. NEVER put hand or fingers over the
spray tip or nozzle. NEVER try to “blow back” fluid; this is

NOT an air spray system.

ALWAYS follow the Pressure Relief Procedure,  below,

before 

cleaning or removing the spray tip or nozzle or servicing

any system equipment.

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

Be sure equipment safety devices are operating properly

before each use.

Medical Treatment

DO NOT TREAT AS A SIMPLE CUT.

Tell the doctor exactly what fluid was injected. For treatment

instructions, have your doctor call the

NATIONAL POISON CENTER NETWORK

Pressure Relief Procedure

To reduce the risk of serious bodily injury, including injection,
always follow this procedure whenever the pump is shut off,
when checking or servicing any part of the system, when in-
stalling or changing spray tips, and whenever you stop spray-
ing.

1.

Close the mixer material valves.

2 .

Open the solvent flush valve(s) and flush until clean.

3 .

Shut off the material and solvent pumps.

4. Open the spray gun or dispensing valve to relieve

pressure.

5 .

If material has hardened in the hose or mixer, close the
material valve, shut off the material and solvent pumps,

and 

 loosen the material inlet hose(s) to relieve

pressure, then remove the dispensing hose.

Spray Gun or Dispensing Valve 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 bodily injury.

Safety Latch 

(If your gun is equipped with one)

Whenever you stop spraying, even for a moment, always set
the gun safety latch in the closed or “safe” position, making
the gun inoperative. Failure to set the safety latch can result in
accidental triggering of the gun.

Diffuser 

(If your gun is equipped with one)

The diffuser breaks up spray and reduces the risk of injection
when the tip is not installed. Check diffuser operation regular-

ly. Follow the  Pressure Relief Procedure,  below, then
remove the spray tip. Aim the gun into a 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 ir-

regular stream, replace the diffuser immediately.

 Guard 

 your gun is equipped with one)

ALWAYS have the tip guard in place on the spray gun while
spraying. The tip guard alerts you to the injection hazard and

helps prevent accidentally placing your fingers or any part of

your body close to the spray tip.

Trigger Guard 

(If your gun is equipped with 

one)

NEVER 

operate the gun with the trigger guard removed. The

guard helps prevent the gun from triggering accidentally if it is
dropped.

Spray Tip or Nozzle Safety

Use 

extreme caution when cleaning or changing spray tips or

nozzle. If the spray tip or nozzle clogs while spraying, engage

the gun safety latch immediately. ALWAYS follow the

Pressure Relief Procedure  and then remove the spray tip to

clean it.

NEVER 

wipe off build up around the spray tip or nozzle until

pressure is fully relieved and the gun safety latch is engaged.

System Pressure

Any misuse of the spray equipment or accessories, such as

Never exceed the maximum working pressure of the lowest

system are properly rated to withstand the maximum air and
fluid working pressures of this system.

NEVER alter or modify any part of this equipment; doing so

could cause it to malfunction.

CHECK all spray equipment regularly and repair or replace

worn or damaged parts immediately.

Material Compatibility

BE SURE that all materials and solvents used are chemically

compatible with the wetted parts shown in the Technical Data
on the back cover. Always read the material and solvent
manufacturer’s literature before using them in this sprayer.
