SAFETY
W
ARNINGS
HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating the 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 bodily
injury, including the need for amputation. Also, fluid injected or
splashed
into the eyes or on the
skin can cause serious damage.
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
, below
,
before cleaning or removing the spray tip or servicing any sys-
tem 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 W
ounds
If any fluid appears to penetrate your skin, get EMERGENCY
MEDICAL CARE AT ONCE. DO NOT TREAT AS A SIMPLE
CUT.
T
ell 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 reconstru
-
ctive
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 bodily injury
.
Safety
Latch
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
The
gun dif
fuser breaks up spray and reduces the risk of fluid in
-
jection 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, hold
-
ing
the gun firmly to the pail. Using the lowest possible pressure,
trigger the gun. If the fluid emitted
is
not
dif
fused into an irregular
stream,
replace the dif
fuser 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 spraying
to reduce the risk of accidentally triggering the gun if it is dropped
or
bumped.
Spray T
ip Safety
Use
extreme caution when cleaning or changing spray tips. If the
spray tip
clogs while spraying, engage the gun safety latch im
-
mediately. ALWAYS follow the PRESSURE RELIEF PROCE-
DURE,
below, and then remove the spray tip to clean it.
NEVER
wipe of
f build–up
around the spray tip until the pressure
is
fully relieves and the gun safety is engaged.
PRESSURE RELIEF PROCEDURE
To
reduce the risk of serious bodily 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
of
f 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.
Engage the gun safety latch.
2. Turn the ON/OFF switch to OFF.
3.

grounded metal pail, and trigger the gun
to
relieve pressure.
5.
Engage the gun safety latch.
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,
VER
Y SLOWL
Y loosen the tip guard retaining nut
or
hose end coupling to relieve pressure gradually
, then loosen
completely.
Now clear the tip or hose.
