Section 3 - Operation
Do’s
• Only allow trained personnel to operate the
Ground Hog and waterblasting equipment.
• Make sure the fuel tank is full at the beginning
of each shift.
• Purge UHP hose for several minutes if the hoses
have been reconnected since the last operation.
• Make sure Ground Hog operators are equipped
with knee high safety boots, protective clothing,
hard hat with a shield or safety goggles, gloves
and OSHA approved hearing protection.
• Make sure the Ground Hog operator has a firm
grip on both handles and is ready before provid-
ing full pressure to the Ground Hog.
• Have a trained support person monitoring the
Ground Hog and UHP power system at all times
during waterblasting operations.
• Visually check all hoses, fittings and Ground
Hog components for leaks or other problems
frequently during waterblasting operations.
• Immediately stop waterblasting operations if
leaks develop or any component of the Ground
Hog or UHP power system is not operating
properly.
• Adjust the pressure for the pavement. Typically
a blast pressure between 32,000 and 38,000 psi
is used.
• Stop blasting before stopping the Ground Hog.
Blasting with the unit stopped will damage the
blasting surface and Hog Head.
• 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.
• Check the pavement frequently and watch the
outer edges of the lines for damage. Continuously
make adjustments as required..
• Always shutdown the UHP power system be-
fore leaving the Ground Hog unattended or
passing it to another person.
• Allow the vacuum system to operate for a
couple of minutes at shutdown to clear vacuum
hoses of water and debris.
Don’ts
• Do not allow untrained personnel to operate
the Ground Hog or waterblasting equipment.
• Do not allow anyone to operate a Ground Hog
without proper safety equipment including
knee high safety boots, protective clothing,
hard hat with a shield or safety goggles, gloves
and OSHA approved hearing protection.
• Do not operate the Ground Hog without a sup-
port person to monitor the UHP and vacuum
power system and be able to immediately shut
it down in an emergency.
• Do not supply full pressure to the Ground Hog
until the operator is ready.
• Do not continue blasting with a damaged nozzle. It
can cause damage, wastewater, reduce the power
of other nozzles and slow production.
• Do not blast directly on sealed joints in the pave-
ment. Especially weather stripping on bridges or
runways.
• Do not blast over pavement markers/reflectors.
Markers can damage the blast head and spray bar
and should be removed prior to blasting.
• Do not blast over damaged or uneven pavement
that can damage the blast head and spray bar.
• Do not continue blasting with fittings, hoses
or components that are leaking or not work-
ing properly.
• Do not operate the Ground Hog if the power
system controls are not operating properly.
• Do not allow the UHP power system to run for
extended periods at maximum RPM when the
Ground Hog control lever is shutdown.
• Do not leave the Ground Hog unattended or
pass it to another person while high pressure
water is being supplied to the blast head.

CROSS THE PATH OF PEOPLE OR EquIPMENT. ALWAYS
MAKE SuRE OTHER MEMBERS OF THE CREW ARE A SAFE
