Graco HIGH EFFICIENCY LOW PRESSURE AA2000 - Manual (Page 3)

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 anyone or at any part of
the body. Never put hand or fingers over the spray tip.
Never try to stop or deflect leaks with your hand or body.
Never try to “blow back" paint; this is not an air spray
gun.
Always follow the Pressure Relief Procedure, at
right, before cleaning or removing the spray tip or
servicing any system equipment.
Check operation of all equipment safety devices
before each use.
Medical Alert - Airless Spray Wounds
If any fluid appears to penetrate your skin, get emer­
gency medical care at once. Do not treat as a sim­
ple 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 treat­
ment 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 safety latch in the closed or
“on safe” position, making the gun inoperative. See
Fig. 3, page 8. Failure to set the safety latch can result
in accidental 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
Pres­
sure Relief Procedure, below, then remove the spray
tip. Aim the gun into a grounded metal pail, holding
the gun firmly to the pail. Using the lowest possible
pressure, trigger the gun. If the fluid emitted is not
diffused into an irregular stream, replace the diffuser
immediately.
Spray Tip Safety
Use extreme caution when cleaning or changing
spray tips. If the spray tip clogs while spraying,
engage the gun safety latch immediately. Always fol­
low the
Pressure Relief Procedure, below, and then
remove the spray tip to clean it.
Never wipe off build-up around the spray tip or air cap
until pressure is fully relieved and the gun safety latch
is engaged.
Pressure Relief Procedure
To reduce the risk of serious injury, including fluid
injection, splashing in the eyes or on skin, or injury
from moving parts, always follow this procedure
whenever pump is shut off, when checking or servic­
ing any part of system, when installing or changing
spray tips and whenever you stop spraying.
1. Engage the spray gun safety latch.
2. Shut off the power to the pump.
3. Close the bleed-type master air valve (required in
system).
4. Disengage the gun safety latch.
5. Hold a metal part of gun firmly to the side of a
grounded metal container and trigger the gun to
relieve fluid pressure.
6. Engage the gun safety latch again.
7. Open pump drain valve (required in system)to
help relieve fluid pressure in the displacement
pump. In addition, open the drain valve con­
nected to the fluid pressure gauge (in a system
with fluid regulation) to help relieve fluid pressure
in the hose and gun. Triggering the gun to relieve
pressure may not be sufficient. Have a container
ready to catch the drainage.
8. Leave drain valve(s) 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
hose end coupling and relieve pressure gradually,
then loosen completely. Now clear the tip or hose
obstruction.
