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 any one or at any part of the body.
NEVER put your hand or fingers over the spray tip. NEVER try
to “blow back” paint; this is NOT an air spray system.

ALWAYS have the tip guard in place on the spray gun when
spraying.

ALWAYS follow the PRESSURE RELIEF PROCEDURE,  be-
low, before cleaning or removing the spray tip 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 Alert––Airless Spray Wounds
If any fluid appears to penetrate your skin, get EMERGENCY
MEDICAL CARE AT ONCE. DO NOT TREAT AS A SIMPLE
CUT
. Tell the doctor exactly what fluid was injected.

Note to Physician: Injection in the skin is a traumatic injury. It
is important to treat the injury surgically as soon as possible. Do
not delay treatment 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.

Safety Latch
Whenever you stop spraying, even for a moment, always set
the gun trigger safety in the closed or “safe” position, making the
gun inoperative. Failure to set the safety latch can result in acci-
dental 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 PRESSURE RELIEF PROCEDURE, be-
low, then remove the spray tip. Aim the gun into a metal pail,
holding the gun firmly to the pail. Using the lowest possible pres-
sure, trigger the gun. If the fluid emitted 

is not diffused into an

irregular stream, replace the diffuser immediately.

Tip Guard
ALWAYS have the tip guard in place on the spray gun while
spraying. The tip guard alerts you to the fluid injection hazard
and helps reduce, but does not prevent, the risk of accidentally
placing your fingers or any part of your body close to the spray
tip.

Trigger Guard
Always have the trigger guard in place on the gun when spray-
ing to reduce the risk of accidentally triggering the gun if it is
dropped or bumped.

Spray Tip Safety
Use extreme caution when cleaning or changing spray tips. If
the spray tip clogs while spraying, lock the gun trigger safety im-
mediately. ALWAYS follow the PRESSURE RELIEF PROCE-
DURE,
 below, and then remove the spray tip to clean it.

NEVER wipe off build–up around the spray tip until the pressure
is fully relieved and the gun trigger safety is locked.

PRESSURE RELIEF PROCEDURE

To reduce the risk of serious injury, including fluid injection,
splashing fluid or solvent in the eyes or on the skin, or injury from
moving parts or electric shock, always follow this procedure
whenever you shut off the sprayer, when checking or servicing
any part of the spray system, when installing, cleaning or chang-
ing spray tips, and whenever you stop spraying.
1. Lock the gun trigger safety.
2. Turn the ON/OFF switch to OFF.
3. Unplug the power supply cord.
4. Unlock the gun trigger safety. Hold a metal part of the gun

firmly to the side of a grounded metal pail, and trigger the gun
to relieve the pressure.

5. Lock the gun trigger safety.
6. Open the pressure drain valve, having a container ready to

catch the drainage. Leave the 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 to relieve the pressure gradually, then
loosen completely. Now clear the tip or hose.
