Before You Start the Pump
Read and follow all instruction manuals, labels and
tags supplied with this pump and with all the accesso-
ries you add to the system, before operating the sys-
tem.
Flush the Pump Before First Use
The pump was tested in lightweight oil. If the oil will
contaminate the fluid you are pumping, flush it out with
a compatible solvent.
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying acci-
dentally. To reduce the risk of an injury from acci-
dental spray from the gun, splashing fluid, or
moving parts, follow the Pressure Relief Proce-
dure whenever you:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray nozzle.
Operation (All Pumps)
1. Shut off the power to the pump.
2. In an air-powered system, close the air regulator
and close the bleed-type master air valve.
3. In a hydraulic-powered system, close the hy-
draulic supply line shutoff valve first, then the
return line shutoff valve. In a multi-pump system,
do this at each pump to isolate the pumps.
4. Close the fluid shutoff valves from the supply
tanks.
5. Trigger the gun at the last gun station to relieve
fluid pressure. Maintain firm metal-to-metal contact
between the gun and a grounded waste pail.
Repeat for all gun stations.
6. Open the pump drain valve to relieve fluid pres-
sure which may be trapped in the pump or hose.
If you suspect that pressure is not fully relieved after
following the steps above, wrap a fitting near the pump
outlet with a rag, and slowly and carefully loosen the
fitting to relieve pressure. Be careful to protect your
eyes from splashing.
