WARNING

Pressure Relief Procedure
4312145D
Pressure Relief Procedure
Follow this Pressure Relief Procedure
whenever you are instructed to relieve
pressure, stop spraying, check or service
equipment, or install or clean spray tip.
1. Engage trigger lock.
2. Shut off pump.
3. Disengage trigger lock.
4. Hold a metal part of the gun firmly to a
grounded metal pail. Trigger the gun to
relieve pressure.
5. Engage trigger lock.
6. Open fluid drain valve (see System
Requirements). Leave drain valve open.
If pressure is not fully relieved:
• Spray tip is clogged. For RAC tip, see
Cleaning Tips/Clearing Clogs, page 6.
For flat tip, slowly loosen tip guard retaining
nut to relieve pressure. Remove and clear
tip.
• Hose is clogged. Slowly loosen hose end
coupling to relieve pressure. Clean hose
obstruction.
System Requirements
• Install a bleed-type master air valve on a
pneumatic pump air supply line to relieve
air trapped between this valve and pump
after air regulator is shut off. Trapped air
can cause the pump to cycle unexpectedly.
• Install a fluid drain valve between the pump
and gun to relieve pressure in displacement
pump, hose, and gun. Triggering to relieve
pressure may not be sufficient. See Pres-
sure Relief Procedure.
Grounding
Check your local electrical code and
pump/sprayer manual for detailed grounding
instructions.
• Spray gun: ground through connection to a
grounded fluid hose and pump/sprayer.
• Fluid hose: use only grounded hoses.
• Fluid supply container: follow local code.
• Object being sprayed: follow local code.
• Solvent flushing pails: follow local code.
Use only conductive metal pails placed on
a grounded surface. Do not place pail on a
nonconductive surface, such as paper or
cardboard, which interrupts grounding
continuity.
• To maintain grounding continuity when
flushing or relieving pressure: hold metal
part of gun firmly to side of a grounded
metal pail, then trigger gun.
Gun Trigger Lock
To prevent injury when the gun is not in use,
always engage the gun’s trigger lock if unit is
being shut down or left unattended. A
wallet-sized warning card with important
injection treatment information is included
with the gun. Additional cards are available at
no charge. Provide a card to all operators.
The trigger lock must move freely, and easily
snap into a locked position. If the trigger lock
is damaged or movement is restricted,
replace with new trigger kit (16) immediately.
