WARNINGS
High Pressure Spray Can Cause Serious Injury
. For Professional Use Only.
Observe All W
arnings. 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 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
.
T
oxicity 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 dif
fuser 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 dif
fuser immediately
.
T
ip 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 T
ip 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 of
f 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 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.
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.

.
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 the pressure gradually, then
loosen
completely
. Now clear the tip or hose.
