Operation
Water Blasting Operation Do’s and Don’ts
Do’s
• STOP blasting before stopping the truck.
Blasting with the unit stopped will damage the
pavement, spray bars and blast heads.
• STOP blasting before changing direction.
• When in doubt, choose a less aggressive spray
bar. It is always best to error on the side of
caution.
• Adjust the forward speed and head rotation
to remove 98% of the paint in a single pass
to eliminate a second pass and more potential
for damage.
• Adjust the pressure for the pavement. Typi -
cally blast pressures between 32,000 and
38,000 psi are used.
• Check and clean the vacuum filters frequently
to ensure strong vacuum pressure while blast-
ing. Dirty filters and low vacuum will leave
excessive paint chips and debris on the pave-
ment slowing productivity.
• Check the charge pressure before blasting
operations begin. Change both filters if charge
water pressure is below 60 psi (4 BARS) before
beginning operations.
• Monitor the water flow to the stuffing boxes
frequently to ensure a steady stream is flowing
to cool and lubricate the packing.
• Monitor charge pressure frequently during
blasting operations to ensure proper charge
water pressure while blasting.
• Check the pavement frequently and watch the
outer edges of the lines for damage. Continu-
ously make adjustments as required.
Don’ts
• Do not allow untrained personnel to operate
Stripe Hog equipment.
• Do not continue blasting with a damaged
nozzle. It can cause damage, waste water,
reduce the power of other nozzles and slow
production.
• Avoid running the blast head wheels on rumble
strips. Always adjust the Hog Arm and the
castor wheel support arms on the blast heads
to keep the wheels off the rumble strips.
• Do not blast directly on sealed joints in the
pavement. Especially weather stripping on
bridges or airfields.
• Do not blast over pavement markers/reflec -
tors. Markers can damage the blast head and
spray bars and should be removed prior to
blasting.
• Do not blast over damaged or uneven pave -
ment that can damage the blast heads and
spray bars.
• Do not allow the debris tank to become over -
filled. This can cause an unexpected shutdown
of the vacuum system. Monitor the tank and
empty it before it is full.
• Do not allow the charge pump to run out
of water. Water is a lubricant that cools the
charge and high pressure pumps. They will be
damaged if they run dry. Always monitor the
water level in the clean water tank and refill
when it gets low.
Waterblasting Procedure
WARNING
THE PROCEDuRE SHOuLD BE FOLLOWED AS OuTLINED
BELOW TO AvOID DAMAGING COMPONENTS ON THE
STRIPE HOG WATERBLASTING SYSTEM, REMOvAL
SuRFACE OR BLASTING HEADS.
1. Complete the startup and setting pressure
procedures.
2. Release the truck park brake and move the
truck to the removal area.
3. Align the truck with the material to be re-
moved, stopping a short distance before the
start point for blasting operations.
4. Rotate the Head Rotation speed dial to set the
spray bar rotation speed to the estimated RPM.
5. Make sure the STOP button in the joystick
console is pressed to open the diverter valve
so no pressure is supplied to the blast heads.
