THE THRU-SHAFT MOTOR BEARINGS MUST BE LUBRICATED
DAILY WITH THE GREASE SPECIFIED IN THE MAINTENANCE
MATRIX. FAILURE TO LUBRICATE THE BEARINGS DAILY OR
USING GREASE OTHER THAN THE GREASE SPECIFIED BY
HOG TECHNOLOGIES WILL VOID THE WARRANTY.
Spray Bars
The spray bar is a quick change design that is
attached to the threaded thru-shaft. Spray bars
are constructed of high quality stainless steel and
available in various sizes ranging from six inches
to thirty six inches. Aggressive and non-aggressive
spray patterns are available for all heads.
Spray bar selection is determined by requirements
of the removal application being performed. The
width of the spray bar selected is critical. It should
be sized to the width of the line or other material
being removed. In most situations, the spray bar
selected should be 2” wider than the width of the
line to reduce the potential for damage and in-
crease productivity by concentrating the blasting
pressure over the painted line.
When selecting a Spray bar the following
should be considered:
• The size of the line marking, the spray bar
should be 2” wider than the marking.
• The type of marking being removed. (Paint,
thermal or rubber)
• The thickness of the material being removed.
• The type of road surface. (Concrete or asphalt)
• Prole requirements per job specications.
Hog Technologies oers a variety of spray bar
congurations to meet requirements of all types
of removal projects. Examples of available spray
bar congurations are included in the Operation
section of this manual. You can also contact our
customer support department for assistance in
selecting the correct spray bar and/or nozzle con-
guration for your project at (877) HOG-ROAD.

NOTICE:
AFTER INSTALLATION OF NEW NOZZLES AND/OR A SPRAY
BAR, THE WEEP HOLES ON ALL HIGH PRESSURE FITTINGS
SHOULD BE CHECKED FOR LEAKS UNDER PRESSURE.
THIS SHOULD BE DONE PRIOR TO REPLACING THE SPRAY
BAR PROTECTORS. THERE SHOULD NOT BE ANY WATER
LEAKING FROM AND WEEP HOLES . ANY LEAKAGE IS AN
INDICATION OF AN INSTALLATION ERROR, NOZZLE NOT
SEATED CORRECTLY OR A DAMAGED COMPONENT.
Before attaching the new spray bar to the
Hog Head Assembly, engage pump at low
pressure to purge the system. Any dirt or
debris in the system can clog nozzle orice’s
and cause system pressure to spike exces-
sively causing damage to components or
the rupture discs on the UHP pump to burst.
