Operation
9. Rotate the Head Rotation speed dial clockwise
to test the spray bar rotation and set the de-
sired rotation speed.
10. With the pressure set and the spray bar and
nozzles working properly, press the STOP
switch on the joystick console so no pressure
is supplied to the blastheads and lower the
blast heads to the pavement. Press the Float
switch to engage Float Mode for the Hog Arm.
11. The truck is now ready to begin waterblasting
operations.
WARNING
ANY CONTACT WITH HIGH PRESSuRE WATER IS vERY
DANGEROuS AND CAN BE FATAL! uSE EXTREME CAuTION
WHILE RAISING OR MOvING HOG HEAD & ARM ASSEMBLY
WHEN HIGH PRESSuRE IS ENGAGED.
3.4 Waterblasting Operations
Overview
Before you start the job, you should evaluate the
pavement and the material to be removed. Choose
the appropriate spray bars and/or nozzles best
suited for the job. You should also consider the
desired or expected profile of the blasted surface
in your selection. There are many variables that
affect blasting efficiency, productivity and the
profile of the blasted surface. As the operator
becomes more experienced, the selection process
becomes more refined and easier.
Generally, large, high volume (.015 - .017) nozzles
are the most aggressive and provide faster re-
sults, but provide greater potential for damage
and a course profile. High volume nozzles should
be used only on strong pavement (concrete or
newer pavement). Small, low volume (.007 -
.011) nozzles are less aggressive and will provide
somewhat slower results but provide less potential
for damage and a smoother profile. Low volume
nozzles are well suited for weak pavement (older
or damaged pavement). Low volume nozzles are
typically a better choice for inexperienced opera-
tors on any surface.
Hog Technologies offers an on-site training pro
-
gram that dramatically reduces the learning curve
and increases productivity. If you are new to
Waterblasting, we highly recommend that you
consider this factory training for your operators.
You can also contact Hog Technologies Customer
Service department for assistance in choosing
spray bars and nozzles or more information re-
garding the factory training program.
CAUTION
THE PAvEMENT WILL BE DAMAGED IMMEDIATELY IF HIGH
PRESSuRE BLASTING IS ACTIvATED WITHOuT THE HOG
HEAD MOvING. ALWAYS MAKE SuRE TRuCK IS MOvING
BEFORE SuPPLYING HIGH PRESSuRE TO THE BLAST
HEADS.
Before Blasting Operations Begin
Evaluate the Pavement and Select a Spray Bar
• Strong pavement withstands high aggression
spray bars. This is generally concrete or new
asphalt.
• Cracked pavement is weak and will require
less aggressive spray bars.
• Brittle pavement is a challenge and will require
less aggressive spray bars and reduced pres-
sure.
• Consider spray bar width. Choose a spray bar
2” wider than the line being removed to pro-
vide steering tolerance plus slight over spray
to reduce the potential for missed areas and
need to back up and re-do sections.
•
Pre-clean the work area with a power broom
if necessary before blasting.
