Hydraulic System Filter
Clean hydraulic fluid that has not been exposed to
excessive temperature or become contaminated
is essential to the performance of the system.
As pumps, cylinders and components wear, they
release tiny metal and rubber particles into the
hydraulic fluid. These particles act as a grinding
compound as they flow through the system. Or -
dinary dirt and water are common hydraulic fluid
contaminants. Any one of these will contribute to
premature failure of hydraulic components. A Fil-
ter on the low pressure hydraulic circuit removes
these contaminates and increases the life of the
fluid and hydraulic components.
The low pressure filter is a cartridge type, spin
on filter. All return fluid passes through the low
pressure filter as it flows back into the tank. The
filter should be changed at the same time the
hydraulic fluid is changed or if it begins to restrict
the return flow.
Hydraulic Manifold
Sectional valves mounted on the tree near the
fluid reservoir make up the hydraulic control
manifold system. An electric solenoid in each valve
activated by switches in the control panel direct
hydraulic pressure to the various components in
the water blasting hydraulic system. The solenoid
valves are a cartridge type design that are easily
replaced in the event of a failure.
Labeled pressure gauges near the manifold moni-
tor system pressure and the pressure of critical
hydraulic circuits. These gauges should be moni-
tored for proper operating pressure several times
during each shift.
Hydraulic Motors
The charge water pump, spray bar thru-shaft,
vacuum blower, vacuum separator drum and the
hydrostatic drive wheel are powered by hydrau-
lic motors. Internal components of the motors
are lubricated and cooled by the hydraulic fluid
that powers the motor. All hydraulic motors have
maximum pressure ratings and RPM settings that
should never be exceeded.
Most hydraulic motors are designed to rotate in
one direction. If a motor needs to be removed
for any reason, always make sure to mark the
hoses and ports so they will be installed in the
correct position. If the hoses are installed in the
wrong ports, the motor will rotate opposite of the

designed rotation which will permanently damage
the motor. Only the motor for the hydrostatic drive
wheel is designed to operate in forward or reverse.
Hydraulic Actuators
Hydraulic actuators are used to raise or lower the
Hog Arm, debris cage, vacuum separator and the
hydrostatic drive wheel.
