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/dispensing,
check or service any of the system equipment,
or install or clean the spray tip/nozzle.
WARNING
Be sure you always shut off the supply line shutoff
valve (E) first, and then the return line shutoff valve
(R). This is to prevent overpressurizing the recipro-
cator or its seals. When starting up the hydraulic
system, open the return line shutoff valve first.
1. Lock the spray gun/dispensing valve trigger safety.
2. Close the supply line shutoff valve (E) first, then
the return line shutoff valve (R). Shut off the hy-
draulic power supply.
3. Unlock the gun/valve trigger safety.
4. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
5. Lock the gun/valve trigger safety.
6. Open the drain valve (required in your ystem),
having a container ready to catch the drainage.
7. Leave the drain valve open until you are ready to
spray/dispense again.
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 tip guard retaining nut or hose end coupling
and relieve pressure gradually, then loosen completely.
Now clear the tip/nozzle or hose.
Before Startup
WARNING
Do not overpressurize the system
To reduce the risk of overpressurizing the system,
which could result in serious bodily injury, including
fluid injection:
Never exceed the maximum working pressure
of the lowest rated accessory in your system
(hydraulic input or fluid output), or the stated
maximum working pressures of this pump.
Regulate the hydraulic input and fluid output
pressures, as appropriate, to maintain safe
working pressures.
CAUTION
Hydraulic Oil Working Temperature
The recommended hydraulic oil operating tempera-
ture is 80 – 115F (27 – 45C). The reciprocator
seals will wear faster and leakage may occur if the
pump is operated at higher oil temperatures.
If the hydraulic oil temperature approaches 130F
(54C), check the hydraulic fluid supply cooling
system, filters, etc. and clean or repair as needed.
WARNING
Be sure the entire system and flushing pails are
properly grounded before flushing. Always use the
lowest possible pressure, and maintain firm metal-
to-metal contact between the gun and pail to
reduce the risk of static sparking and splashing.
Maintain firm metal-to-
metal contact between
gun and grounded
metal pail.
Before you start the pump, check the hydraulic fluid
level, and add fluid as necessary to fill the lines.
Flush the pump before using it for the first time to
remove the light oil which was left in after factory test.
Be sure the solvent used is compatible with the fluid to
be sprayed and the wetted parts of the pump.
