WARNING
If there are leaks, shut off the pump immediately and
release system pressure follow the “Pressure Relief
Procedure” then tighten connections, start the pump
again and check to be sure leaking has stopped.
Always use the lowest air pressure necessary to get the
desired results, Higher pressures waste fluid and cause
premature wear of the pump packings and spray tips.
Never allow the pump to run dry of the fluid being
pumped because a dry pump will quickly accelerate to a
high speed, possibly damage itself.
If the pump accelerates quickly or is running too fast,
shut off pump immediately and check the fluid supply.
SETTING UP TO SPRAY
Always follow the “Pressure Relief Procedure” before
cleaning, or removing the equipment or servicing any
part of system equipment.
Immerse the pump intake or suction tube in paint.
Make sure drain valve is open.
Start the engine.
Open the hydraulic ball valve to allow hydraulic
fluid to flow to hydraulic motor.
Paint pump should start to pump material and you
should notice material flowing out to prime valve.
Let the pump run until the material is flowing evenly
out of prime valve.
Close the prime valve and unit should now build up
with pressure.
Run the pump until paint flows smoothly from the
gun, without spitting, release the trigger.
Adjust the pump to the minimum pressure required
to obtain the desired spray pattern of paint. If
atomization is not possible on thick paints,
thin with the compatible solvent.
NOTE:
The pump will stall out (stop) against the
pressure without any damage to the pump.
MAINTENANCE
DAILY SHUTDOWN PROCEDURE”
Close the on-off air valve to the pump.
Always be sure to stop the pump at the bottom
of the stroke to prevent paint from drying on the
displacement rod and damaging the throat packings.
Always bleed off the paint pressure in the system by
triggering the gun and opening the drain valve,
making sure to have a container ready to catch the
paint draining from the drain valve.
Remove the tip from the gun and clean and leave it
in solvent until ready to use again.
Do not disconnect the gun or hoses, keep the unit
filled with solvent to reduce the need for flushing.
NOTE:
When using fast drying paints, immerse the suction
tube in a container of solvent during shutdown.
Clean the pump’s intake screen.
SHUTDOWN FOR STORAGE
Always follow the “Pressure Clearance Procedure” and
when storing the unit proceed as follows:
Flush the unit clean, as instructed . It may take re-
peated flushing with solvent or water, to clean the sys-
tem thoroughly.
Fill the pump, hoses, and gun full of solvent. If the
flushing solvent used as water or a keytone type
solvent, fill the system with mineral spirits or light oil
for storage over a long period. Wipe all external wet-
ted parts of the pump with oil. Make sure that water or
keytone solvent is removed from the wet cup/ packing
nut.
Use the lowest pressure setting possible.
If the pump accelerates quickly or is running too
fast, stop the pump immediately and check the mate-
rial supply.
Don’t leave a pump shut off for a long period of
time, if the material supply has been exhausted and
air has been pumped into the lines. This can cause
the material possibly to dry in the lines.
Prime the pump and lines with material or flush and
leave filled with solvent, with the pressure relieved.
