Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
Fluid under high pressure can be in-
jected 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:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray tip.
1.
Lock the spray gun trigger safety.
2.
Shut off the main power to the heater, if used.
Circulate the fluid for at least 10 minutes to allow it
and the heater to cool.
3.
Close the bleed-type master air valve (supplied in
your system).
4.
Shut off the air regulators.
5.
Unlock the spray gun trigger safety.
6.
Hold a metal part of the spray gun firmly to the
side of a grounded metal pail, and trigger the
spray gun to relieve pressure.
7.
Lock the spray gun trigger safety.
8.
Open the drain valve (supplied in your system),
having a container ready to catch the drainage.
9.
Leave the drain valve 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
air cap or hose end coupling and relieve pressure
gradually, then loosen completely. Now clear the tip or
hose.
WARNING
For your safety, before operating the equipment be
sure all operators have read and fully understand
all the warnings, cautions, and instructions in this
manual and all manuals supplied with each compo-
nent or accessory.
Flush the Pump Before Using
Pumps are tested with lightweight oil which is left in to
protect the pump parts. To prevent contamination of
the fluid, flush the pump with a compatible solvent
before using it.
WARNING
Before flushing, be sure the entire system and
flushing pails are properly grounded. Refer to
Grounding
on page 5. Follow the
Pressure
Relief Procedure
at left, and remove the spray tip
from the gun. Always use the lowest possible fluid
pressure, and maintain firm metal-to-metal contact
between the gun and the pail during flushing to
reduce the risk of fluid injection, static sparking,
and splashing in the eyes or on the skin.
Starting and Adjusting the Pump
Be sure the air regulators (31) and bleed-type master
air valve (62) are closed.
Do not install the spray tip
yet!
Place the suction tube (23) in the fluid pail. Open the
drain valve (65) for priming. Open the bleed-type
master air valve and the gun air regulator (clockwise).
Hold a metal part of the spray gun firmly to the side of
a grounded metal pail and trigger the gun. Slowly open
the pump air regulator (clockwise) until the pump
starts. Allow the pump to cycle slowly until all the air is
pushed out of the fluid lines. Release the gun trigger
and engage the safety latch; the pump will stall against
the pressure.
With the pump and lines primed, and with adequate air
pressure and volume supplied, the pump will start and
stop as the spray gun is triggered and released.
Follow the
Pressure Relief Procedure Warning
at
left, then install the spray tip in the gun.
