P
ARTS HAZARD
KEEP
HANDS AND FINGERS A
WA
Y FROM THE PRIMING PIST
ON
DURING OPERA
TION AND WHENEVER THE PUMP IS CHARGED
WITH
AIR to reduce the risk of injury!
On the pump downstroke the
priming
piston extends beyond the intake cylinder
to pull the material into
the
pump. The priming
piston works under extreme force. During opera
-
tion
and whenever the pump is charged with air
, the priming piston can
severely
injure or amputate a hand or finger
, or break a tool, caught be
-
tween
it and the intake cylinder
. Always
follow the
Pressure Relief Pro
-
cedure,
below
, before checking, clearing, cleaning, flushing or
servicing
any
part of the pump.
The air motor piston (located behind the air motor shield) also moves
when
air is supplied to the motor
. NEVER operate the pump
with the air
motor
shield removed.
Before servicing the pump, follow the
Pressure
Relief
Procedure
below to prevent the pump
from starting accidentally
.
FLUID INJECTION HAZARD
General
Safety
This
equipment generates very high fluid
pressure. Spray from the gun/
valve,
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 gun/valve at anyone or
at any part of the body
. NEVER
put
hand or fingers over the spray tip/nozzle, or over the bleeder valve
hole.
ALWAYS
follow the
Pressure Relief Procedure
, right, before
cleaning
or
removing the spray tip/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
Alert––Airless Spray W
ounds
If
any fluid appears
to penetrate your skin, get
EMERGENCY MEDICAL
CARE
A
T
ONCE. DO NOT TREA
T 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 im
-
portant
to treat the injury surgically as soon as possible
. Do
not
delay
treatment to research toxicity
. T
oxicity is a concern with some ex
-
otic
coatings injected directly into the blood stream. Consultation with a
plastic
surgeon or reconstructive hand surgeon may be advisable.
Spray
Gun/Dispensing V
alve Safety Devices
Be
sure
all gun/valve safety devices are operating properly before each
use.
Do not remove or modify
any part of the gun/valve; this can cause a
malfunction
and result in serious bodily injury
.
Safety
Latch
Whenever
you stop spraying/dispensing, even for a moment, always
set
the
gun/valve safety latch in the closed or “safe” position, making the gun/
valve
inoperative. Failure to set the safety latch can result in accidental
triggering
of the gun/valve.
Trigger
Guard (only on spray guns)
Never
operate the spray gun with the trigger guard removed. This guard
helps
prevent the spray gun from triggering accidentally if it is dropped or
bumped.
Diffuser
(only on spray guns)
The
spray gun dif
fuser breaks up spray and reduces the risk of fluid injec
-
tion
when the tip is not installed. Check the dif
fuser operation regularly
.
Follow the Pressure Relief Procedure, to the right, then remove the
spray
tip. Aim the spray gun into a grounded metal pail, holding the spray
gun firmly to the pail. Using the lowest possible pressure, trigger the
spray
gun. If
the fluid emitted is not dif
fused into an irregular stream, re
-
place
the dif
fuser immediately
.
Tip
Guard (only on spray guns)
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.
Spray T
ip/Nozzle Safety
Use
extreme caution when cleaning or
changing spray tips/nozzles. If the
spray
tip/nozzle clogs while spraying/dispensing, engage the
gun/valve
safety
latch immediately
. ALWAYS follow the
Pressure Relief Proce
-
dure
and then remove the spray tip/nozzle to clean it.
NEVER
wipe of
f build–up around the spray tip/nozzle until pressure is
fully relieved and the gun/valve safety latch is engaged.
Pressure
Relief Procedure
To
reduce the risk of serious bodily injury
, including fluid injection,
splashing
in the eyes or on the skin, or injury from moving parts,
always follow this procedure whenever you shut of f the pump,
when
checking or servicing any part of the spray/dispensing sys
-
tem,
when installing, cleaning
or changing spray tips/nozzles, and
whenever
you stop spraying/dispensing.
1.
Engage the gun/valve safety latch.
2.
Shut of
f the air to the pump.
3. Close
the bleed–type master air valve (required in your sys
-
tem).
4. Disengage
the safety latch.
5. Hold a metal part of the gun/valve firmly to the side of a
grounded
metal pail,
and trigger the gun/valve to relieve pres
-
sure.
6. Engage
the gun/valve safety latch.
7. Open
the drain
valve and/or the pump bleeder valve (required
in
your system), having a container ready to catch the drain
-
age.
8. Leave
the drain valve open until you are ready to
spray/dis
-
pense
again.
If you suspect that the spray tip/nozzle or hose is completely
clogged,
or that pressure has not been fully relieved after following
the steps above, VERY SLOWL
Y loosen the tip guard retaining
nut,
nozzle, or hose end coupling and relieve pressure
gradually
,
then
loosen completely
. Now clear the tip/nozzle or hose.
