from the use of such chemical components.
Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the spray tips.
1. Lock the spray gun trigger safety.
2. Shut off the power supply to the pump.
3. Close the bleed-type master air valve (required in
air-powered systems).
4. Unlock the spray gun trigger safety.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
6. Lock the spray gun trigger safety.
7. Open the fluid drain valve (required in your sys-
tem); have a container ready to catch the drain-
age.
8. Leave the fluid drain valve open until you are ready
to spray again.
9. If you suspect that the spray tip or hose is com-
pletely clogged, or that pressure has not been fully
relieved after following the steps above, very
slowly loosen the tip guard retaining nut or hose
end coupling and relieve pressure gradually, then
loosen completely. Now clear the tip or hose.

Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 3.
1. Pump: use a ground wire and clamp as shown in
your separate pump manual.
2. Air or hydraulic hoses: use only electrically con-
ductive hoses.
3. Fluid hoses: use only electrically conductive fluid
hoses.
4. Air compressor or hydraulic supply: follow the
manufacturer’s recommendations.
5. Spray gun: ground by connecting the gun to a
properly grounded fluid hose and pump.
6. Fluid supply container: follow your local code.
7. Object being sprayed: follow your local code.
8. Solvent pails used when flushing: follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the
pail on a nonconductive surface, such as paper or
cardboard, which interrupts the grounding continu-
ity.
9. To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded metal pail,
then trigger the gun.
