to turn freely. The hose is secured to the thru-
shaft motor by the swivel nut. The swivel nut is
hand tightened. If the nut becomes loose, the
hose will wobble and damage the swivel seal.
Additionally, if the swivel nut is overtightened by
using a pipe wrench or pliers, the swivel seal will
be damaged. It must be checked daily to ensure
it is tight and that the swivel seal is not leaking.
Any water dripping from the weep holes just
below the swivel nut while the system is pres-
surized indicates the seal is leaking and must be
replaced. Operating the Hog Head with a leaking
swivel seal will cause complete failure of the seal,
stopping blasting operations and severely damage
the thru-shaft motor.
The spray bar is a quick change design. Spray
bars are available in 6”, 8”, 10”, 14”, widths. Ag-
gressive and non-aggressive patterns are available
for all heads.
If you are new to waterblasting equipment, Hog
Technologies offers a variety of spray bar and
nozzle configurations to meet the requirements of
most paint and rubber removal projects. Please
contact Hog Technologies Customer Service for
assistance in selecting the right spray bars for
your project.
To change a spray bar, hold the shaft by inserting
a 3/4” wrench into the slot at the bottom of the
thru-shaft motor, located just above the blast head
shroud. Twist the spray bar counterclockwise by
hand until it is free of the shaft. Purge the blast
head at low pressure, then apply anti-seize to the
threads, insert a new brass button seal and install
the new spray bar by turning it clockwise slowly
until it seats. Then tighten it by turning the spray
bar another 15%. Make sure you remove the
wrench when the installation is complete.
Notice:
Before attaching the new spray bar to the
Hog Head Assembly, engage pump at low
speed to purge the system. Any dirt or debris
in the system can clog nozzle orifice’s and
cause system pressure to spike excessively
causing damage to components or the rup-
ture disc on the UHP pump to burst. Refer
to the Stripe Hog Training DVD for detailed
information on changing the spray bar.
The dirt shield that protects the thru-shaft motor
is located between the spray bar and blast head
shroud. It consists of a special felt seal that is
held against the bottom of the blast head shroud
by a stainless steel flat washer threaded on the
shaft. The felt seal should be inspected and ad-
