fuse in the control switch panel protects the bilge
pump circuit from an overload.
Water drains from the high pressure pump by
gravity to a sump box equipped with an automatic
switch that is connected to the bilge pump. When
the water level in the sump box raises enough to
activate the automatic switch, the bilge pump is
activated and pumps the water from the sump
box to the debris tank. When the water level in
the sump box is lowered, the switch will turn the
pump off.
The sump automatic switch and inside of the sump
box are accessed by removing the sump box lid.
It is important to periodically remove the lid to
inspect the switch and clean out accumulated
debris that can restrict water flow to the pump.
Ultra High Pressure System
Clean, fresh water is supplied to the high pressure
pump by the charge pump. The high pressure
pump is powered by the main truck engine through
the OMSI Drive PTO that is activated by the PTO
switch in the control panel. The OMSI PTO switch
also activates the solenoid which enables the hy-
draulic rotation of the spray bar that is controlled
by the Head Rotation dial. The transmission PTO
switch on the truck dash activates the hydraulic
system. Green LED lights in the console switches
illuminate to indicate the pump and spray bar hy-
draulic rotation are activated. When the system
is activated, the Dump Valve switch activates or
turns off the high pressure water to the Hog Head
spray nozzles.
When the high pressure is turned off by the switch,
the diverter valve (Dump Valve,) located on the
UHP pump is activated to divert the water from
the Hog Head pressure lines to the bypass line and
back to the clean water tank. The Dump Valve is
a safety feature that enables the high pressure
water supply to the blast head to be immediately
reduced to less than 500 PSI (34.474 Bar) at any
time without causing damage to the high pressure
lines and components.
Maximum operating pressure for the UHP pump of
40,000 PSI (2,758 Bar) @ 8.5 gallons (32 Liters)
per minute is achieved at maximum engine RPM.
(typically 2300 RPM) The water pressure is moni -
tored by the High Pressure gauge on the pump
and a digital gauge in the control panel. High
pressure is controlled by the RPM of the engine
and/or by adjusting the manual bypass valve on
the pump. Since engine RPM also controls the

level of vacuum, adjusting the pressure using the
manual bypass valve is beneficial when maximum
engine RPM is required for vacuum and less than
maximum waterblasting pressure or gallons per
minute is desired for the material being removed
or the waterblasting tools being used.
The UHP system is activated by engaging the OMSI
Drive PTO and setting engine RPM to the desired
operating pressure setting (typically 1800 RPM -
2300 RPM max.) There may be some variation of
this depending on the engine and other compo-
nents unique to your unit. When setting pressure
ALWAYS ensure that the system pressure drops to
less than 500 PSI (34.475 Bar) immediately when
the Dump Valve switch is turned off. If this does
not relieve system pressure immediately to below
500 PSI when released, do not use the equipment
until repairs are made to the dump valve.
The high pressure pump is a positive displacement
pump that requires a constant water supply at
a minimum of 30 PSI (2.1 Bar) from the charge
water system to operate properly. Always make
sure there is enough water in the tank before en-
gaging the PTO systems to activate the UHP and
charge pumps. Pressure gauges for the charge
water system are near the water filters and on
the control panel. Pressure gauges for the UHP
system are located on the UHP pump and on the
control panel. The gauges should be monitored
frequently whenever waterblasting operations are
underway. If the pressure rises or drops outside of
the normal operating range in either system, stop
waterblasting operations immediately, turn off the
charge pump and disengage the PTO. Then find
