Pumptec Operating Instructions and Parts Manual PRESSURE WASHER
positive displacement pumps providing a specific amount of
fluid constantly while operating. This volume of fluid must
be directed out thru a nozzle or back to a tank because it
cannot be stopped completely without creating excessively
high pressure and risk of damage to pump, components,
property and person. It is recommended a safety device such
as a regulating valve be installed directly on pump head as
protection in case of a failure of another component. Pressure
switches can be used to automate pump operation, but they
must have a pressure regulating device installed as a safety
device.
Fluid can enter a pump either from a filtered tank or
pressurized fluid line.
It is common to use a tank with pumps that are mounted above
the pump. Filtration is important to maintain proper function
of the pump and system. The extent of filtration may be greater
based upon some uses such as misting with ultra-fine nozzles.

1. Check water supply. Is there water in tank? Is the garden
hose “on” ?
2. Check for leaks.
3. Check line Strainer, Clean?
4. Disconnect coupler on inlet side of unloader, direct hose
back to tank or onto ground away from motor
Start pump and allow air to purge from system (5 -15
seconds)
Stop pump and reconnect bypass hose to inlet side of
unloader
5. Connect discharge hose to outlet side of unloader
Connect spray gun assembly to other end of hose assembly
6. If you have a variable nozzle, adjust nozzle to low pressure

7. If you have separate nozzles with quick connects remove
nozzle from spray gun
8. Unscrew knob on unloader 4-6 turns to adjust to low
pressure setting
9. Hold trigger open on spray gun and start pump
Allow all air in system to purge
Stop pump
Adjust variable nozzle to high pressure (pull nozzle back
toward gun)
-OR-
Install quick connect high pressure nozzle
10. Restart Motor and squeeze spray gun trigger and adjust
spray angle to appropriate position.
gradually increase pressure by adjusting unloader knob
Adjust pressure to suitable pressure for the specific cleaning
task.
nOTE: Higher pressure requires more amperage. Do not
unnecessarily overload the system. This could result in the
premature failure of the motor and void your warranty.

nOTE: 12 Volt pumping systems are unique in that “problems”
are most likely to be electrical. If the pump motor is running
and no water is coming out of the pump - you have a pump
