Graco A Series Instructions Manual page 2

High Pressure Spray Can Cause Serious Injury. For Professional Use Only.
Observe All Warnings. Read and understand all instruction manuals before operating equipment.
General Safety
This equipment generates very high fluid pressure. Spray
from the gun/dispensing 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 spray gun/dispensing valve at anyone or at
any part of the body. Never put hand or fingers over the spray
tip/nozzle. 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, 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 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 into 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. Tox-
icity 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/Dispensing Valve Safety Devices
Be sure all spray gun/dispensing valve safety devices are
operating properly before each use. Do not remove or modify
any part of the spray gun/dispensing 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 safety latch in the closed or "safe" position,
making the spray gun/dispensing valve inoperative. Failure to
set the safety latch can result in accidental triggering of the
spray gun/dispensing valve.
Trigger Guard (if so equipped)
Never operate the spray gun/dispensing valve with the trigger
guard removed. This guard helps prevent the gun/dispensing
valve from triggering accidentally if it is dropped or bumped.
WARNINGS
FLUID INJECTION HAZARD
Diffuser (only on spray guns)
The spray gun diffuser breaks up spray and reduces the risk
of fluid injection when the tip is not installed. Check the dif-
fuser operation regularly. Follow the Pressure Relief Proce-
dure, below, 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 diffused into an irregular stream,
replace the diffuser 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 acciden-
tally placing your fingers or any part of your body close to the
spray tip.
Spray Tip/Nozzle Safety
Use extreme caution when cleaning or changing spray tips/
nozzles. If the spray tip/nozzle clogs while spraying/dispens-
ing, engage the safety latch immediately. Always follow the
Pressure Relief Procedure and then remove the spray tip/
nozzle to clean it.
Never wipe off build-up around the spray tip/nozzle until pres-
sure is fully relieved and the safety latch is engaged.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including fluid injec-
tion, splashing in the eyes or on the skin, or injury from mov-
ing parts, always follow this procedure whenever you shut off
the pump, when checking or servicing any part of the spray/
dispensing system, when installing, cleaning or changing
spray tips/nozzles, and whenever you stop spraying/dispens-
ing.

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 slowly loosen the retaining
nut or hose end coupling and relieve pressure gradually, then
loosen completely. Now clear the tip/nozzle or hose.
Engage the spray gun/dispensing valve safety latch.
Shut off the air or hydraulic fluid to the pump.
Close the bleed-type master air valve (required in air-
powered systems).
Disengage the spray gun/dispensing valve safety latch.
Hold a metal part of the spray gun/dispensing valve
firmly to the side of a grounded metal pail, and trigger the
gun/dispensing valve to relieve pressure.
Engage the spray gun/dispensing valve safety latch.
Open the drain valve (required in your system), having a
container ready to catch the drainage.
Leave the drain valve open until you are ready to spray
again.
