Section 1:
1.1 General Safety
Use Professional Training
Operating high pressure water blasting equipment
requires professional training, including safe work
practices and procedures. Only professionally
trained personnel should be allowed to setup,
operate, or maintain high pressure water blasting
equipment. If you have not completed the Hog
Technologies basic training course you will be a
danger to yourself and others. The velocity of water
at the nozzle tip exceeds that of a bullet coming out
of a gun. Contact with the high pressure blast can
result in the loss of a limb or water injection into
the bloodstream. If injection occurs in a vulnerable
part of the body death may result.
Always Read Instructions
Read this manual and all other water blasting
equipment operation manuals and instructions
prior to using any Waterblasting product. Contact
Hog Technologies (877-HOG ROAD) should any
questions arise.
Major Component Operation Manuals
The suppliers of some major components such as
engines, electric motors and pumps, provide their
own operation manuals which have been included
with your equipment. You should read the infor-
mation in this manual and the manuals of other
manufacturers completely and have a thorough
understanding of all component systems and their
proper operation before operating your equipment.
REMEMBER - IT IS YOUR RESPONSIBILITY
TO ENSURE THAT YOUR EQUIPMENT IS SAFE
FOR YOU AND YOUR CREW. ALWAYS EXER-
CISE GOOD JUDGMENT WHEN INSTALLING
OR REPAIRING EQUIPMENT AND WHILE
OPERATING WATER BLASTING EQUIPMENT.
Work Area Safety
Remember, safety is rst! Only set up to work in
areas properly protected from trac and other
hazards. Individuals being struck by vehicles or
mobile equipment lead to many work zone fatali-
ties or injuries. Work zones need trac controls
identied by signs, cones, barrels and barriers.
You should always wear high visibility clothing
with a uorescent background and made of retro-
reective material to be more visible to motorists
and reduce the possibility of an accident. Work
stations should always be illuminated.
Outt all operators with proper safety apparel. Al-
ways use eye protection to shield from projected
debris. Use ear protection to protect from noise
levels generated from pump, vacuum and water
blasting head. It is very important to wear steel
toed boots that provide good traction on slippery
surfaces.
Never wear loose clothing. Loose clothing can get
caught on moving or rotating parts causing serious
injury or even death.
Most ultra-high pressure water blasting operations
generate noise levels above 90 dB. Hearing protec-
tion is required in accordance with OSHA standards.
OSHA’s Permissible Noise Exposure
90 dB 8.0 hours
92 dB 6.0 hours
95 dB 4.0 hours
97 dB 3.0 hours
100 dB 2.0 hours
102 dB 1.5 hours
105 dB 1.0 hours
110 dB 30 minutes
115 dB 15 minutes
WARNING
ALL PERSONNEL EXPOSED TO 90 DB OR GREATER
NOISE LEVELS SHOULD RECEIVE INSTRUCTION IN THE
CORRECT USE OFEAR PROTECTION SO THAT THEIR NOISE
EXPOSURE LIES WITHIN THE LIMITS SPECIFIED BY OSHA.
NEVER ALLOW ANYONE NEAR THE WORK AREA WITHOUT
PROPER EAR PROTECTION.
REMEMBER: ULTRA-HIGH PRESSURE BLASTING CAN
CAUSE DEBRIS TO BE PROJECTED UNEXPECTEDLY IN
ANDAROUND THE WORK AREATHAT CAN CAUSE SEVERE
INJURY. MAKE SURE ALL PERSONNEL STAY CLEAR OF
THE BLASTING AREA AND USE HARD HATS, EYE AND EAR
PROTECTION.
Always be sure your work area is clear of people
whenever the ultra-high pressure pump is en-
gaged.

death. Alterations without manufacturer consent
will void the warranty.
Inspect Equipment
Inspect the condition of all components prior to
use. Do not use any item that is in questionable
condition. Use only components which are marked
with the recommended operating pressure. Never
exceed the operating pressure of the weakest
component in the system.
IMPORTANT NOTE:
SOME HOG TECHNOLOGIES EQUIPMENT USES INTERNAL
COMBUSTION ENGINES AND FLAMMABLE FUEL. EVERY
PRECAUTION HAS BEEN TAKEN BY HOG TECHNOLOGIES
TO REDUCE THE RISKS ASSOCIATED WITH POSSIBLE
INJURY AND DAMAGE FROM FIRE OR EXPLOSION, BUT
YOUR OWN PRECAUTION AND GOOD MAINTENANCE
PROCEDURES ARE NECESSARY TO ENSURE THE SAFE
OPERATION OF YOUR EQUIPMENT.
Store Components Properly
Protect all components from damage when not in
use. Secure for travel.
Freezing Conditions
Water and vacuum systems, hoses and the water
blasting head should be drained of all water or
lled with an antifreeze solution. For the 40K pump
system, refer to pump manufacturer’s procedures
for maintaining equipment in freezing climates.
Prior to starting operations, the operation of all
equipment components must be checked carefully
to ensure they are not frozen, have not been dam-
aged by frozen water and are operating properly.
1.2 Blasting Safety
Safety First – ALWAYS!
Whenever the high pressure pump is engaged for
setting pressure or operations, always be sure
work area is clear of people, hands, feet, etc.
before engaging the high pressure.
WARNING
INJURIES FROM ULTRA-HIGH PRESSUREWATER BLASTING
ARE VERY SERIOUS AND CAN RESULT IN A FATALITY.
ALWAYS MAKE SURE ALL PERSONNEL ARE A SAFE
DISTANCEFROM THE WORKAREABEFORE THEPRESSURE
PUMPIS ENGAGED. NEVER PUT HANDS,FEET ORANY PART
OF YOUR BODYIN OR NEAR THE HIGH PRESSURE STREAM.
Equip All Personnel with Proper Safety Gear
Handheld waterblasting equipment can be ex-
tremely dangerous if proper precautions are not
observed. Operators handling the waterblasting
devices must be extremely carefully and wear pro-
tective gear designed for waterblasting. Remem-
ber that high pressure can instantly cause severe
injury or death if any part of the body is contacted

13
Section 1 - Safety Information
by the high pressure stream. Waterblasting tool
operators must be equipped with the following;
heavy duty, steel toed, non-skid knee high boots,
a heavy duty, protective rain suit, gloves, hard hat
with safety shield or goggles and ear protection.
Support team operators should be equipped with
a minimum of steel towed, non-skid safety boots,
heavy duty work clothes, gloves, hard hat, safety
glasses or goggles and ear protection.
WARNING
ULTRA-HIGH PRESSURE BLASTING CAN CAUSE DEBRIS
TO BE PROJECTED UNEXPECTEDLY IN AND AROUND
THE WORK AREA THAT CAN CAUSE SEVERE INJURY.
MAKE SURE ALL PERSONNEL STAY WELL CLEAR OF THE
BLASTING AREA AND USE HARD HATS, EYE AND EAR
PROTECTION.
DANGER
AVOID SERIOUS INJURY OR DEATH. NEVER APPROACH
A PERSON THAT IS RUNNING A HAND TOOL DURING UHP
OPERATIONS UNLESS THE PERSON CAN SEE YOU. MAKE
SURE THAT THE PERSON STOPS BLASTING BEFORE YOU
GET WITHIN RANGE OF POTENTIAL BLAST.
WHEN BLASTING, NEVER TURN AROUND SUDDENLY
WITHOUT STOPPING THE PRESSURE FIRST IN CASE
A PERSON HAS APPROACHED YOU WITHOUT YOUR
KNOWLEDGE.
ALWAYS STOP THE PUMP BEFORE PASSING THE TOOL.
Check Water Supply
Use only clean water in any ultra-high pressure
system. DO NOT accept water drawn from reten-
tion ponds, canals or other non-potable sources.
Purge System
Before attaching a spray bar to the Hog Head as-
sembly, engage the high pressure pump at low
speed to purge the system. Any dirt or debris
in the system can clog nozzle orices and cause
system pressure to spike excessively, causing
damage to components.
Check Water Blasting Head
Check the blasting head and spray bar for smooth
and proper operation before each shift. Do not use
equipment that has not been checked thoroughly.
Check Control Components
Check all controls, switches and control panel
devices to ensure each is working properly before
beginning operations. Do not use equipment if any
device is malfunctioning.
Know Your Surroundings
Always be aware of, and pay attention to your
surroundings. – i.e. - pump, hoses, people, walls,
moving vehicles, live lanes of trac, etc.
Test System
With the spray bar and high cohesive nozzles
installed, operate the pump at low pressure to
check for nozzle accuracy and leaks in spray bar,
connections or nozzles. Should any repairs or
adjustments be necessary, disengage the pump
to relieve all pressure before making any required
repairs or adjustments.
Always Use At Least Two Operators.
For safety purposes, at least two operators should
always be present during waterblasting opera-
tions with one tool and three operators present
when operating two tools. The primary operator
handling the waterblasting tool must have direct
control of the water pressure. The secondary
operator (assistant), should observe operations
from a safe distance (at least 12 feet (366 cm)
and be able to shutdown system pressure from
a secondary control to quickly relive pressure in
case of an emergency.
Brace Yourself and Be Prepared
Operators of handheld tools should always be
braced and maintain rm, solid footing at all times
before beginning pressure testing the system
or blasting. Be ready, if water volume from the
pump is excessive. Excessive force from the spray
bar can be enough to lift the Ground Hog o the
ground causing loss of control and/or the blast to
cross the path of people or equipment. Always
make sure other members of the crew are a safe
distance from the operator before blasting opera-
tions begin to ensure there is no chance for them
to come in contact with the high pressure stream
if the operator loses control.
If waterblasting in a man lift, on scaolding or
above ground level, always use a fall protection
device such as safety belts, harnesses, and fall
nets. Never operate handheld waterblasting
equipment while standing on slippery surfaces.

14
Section 1 - Safety Information
CAUTION
TOAVOID POSSIBLE INJURYAND DAMAGE TO EQUIPMENT,
USE ONLY THOROUGHLY TRAINED PERSONNEL TO
PERFORM MAINTENANCE OR REPAIRS. ALWAYS TESTALL
COMPONENTS AT LOW PRESSURE.
Start at Low Pressure
Always start blasting with the system at low
pressure and slowly increase RPM to operating
pressure. Engage and disengage the high pres-
sure control lever two times at operating pressure
to check the operation of the blasting head and
control valve before starting blasting operations.
Set System Pressure
With system operating properly, set your pressure
according to methods described by pump manu-
facturer’s instructions. Refer to the pump oper-
ating manual for specications and instructions.
Check Dumping Pressure
When setting pressure ALWAYS ensure that the
system pressure drops to less than 100 psi (7
bar) immediately when the DUMP VALVE control
lever is released. If this does not relieve system
pressure immediately to below 100 psi (7 bar)
when released, do not use the unit until repairs
are made.
Use the Minimum Pressure Required
Do not exceed the operating pressure of the sys-
tem’s lowest pressure-rated component. All equip-
ment pressure rating and warning tags should be
left intact.
Be Prepared
If the equipment malfunctions or a malfunction is
suspected, immediately stop all blasting activity
and relieve the pressure in the system before at-
tempting any repair. Always follow manufacturer’s
repair instructions.
Never Blast When the Tool is Stopped
Always make sure High Pressure switch or lever
is OFF BEFORE motion is stopped. Damage to
the surface will occur if blasting continues when
high pressure is supplied to a waterblasting tool
that is not moving.
Stop the Pump Before Passing the Tool
Passing o handheld waterblasting tools is ex-
tremely dangerous due to the possibility of ac-
cidental trigger activation.
When passing a Hand Hog tool to another person,
always stop the pressure then, place the unit
safely on the ground. Once the unit is neutralized
and secure, the other person can take possession
of it and begin working again.

15
Section 1 - Safety Information
1.2 Nozzle Safety
Check Flow Rating
Combined nozzle ow rate must be compatible
with the pump discharge and pressure rating.
Refer to the nozzle ow chart in this manual.
Check Pressure Rating
Use only nozzles with a manufacturer’s pressure
rating of at least the pump’s operating pressure
or a burst rating of no less than 60,000 psi (4,137
BAR.)
Check Orices
Prior to installation, make sure the nozzles have
no clogged orices. Also, check to ensure nozzles
are sharp and not excessively worn.
Check Connections
Be sure to never force a nozzle into the blasting
head. Clean threads to ensure nozzle is not cross-
threading. Use an ample amount of anti-seize
on threads only, never on the seat of the nozzle.
Inspect the seat area on nozzle to ensure a tight
seal. If it is damaged, do not use.
Clogged Nozzles
If a nozzle appears clogged, immediately disen-
gage pump. Remove any clogged nozzles and
replace with new nozzles. Any particles of the
smallest size will clog nozzles. Clogged nozzles
can create excessive pressure in pump.
Remove Nozzle from Service if:
A) Nozzle is split or damaged.
B) Nozzle is clogged.
C) Nozzle water spray is fanned out.
D) Nozzle’s ability to hold pressure is suspect.
E) Nozzle’s hex head is worn excessively from
blasting.
F) Nozzle threads are damaged.

Section 1 - Safety Information
1.3 Hose Safety
General
Ultra-High Pressure hoses are tough, but not in-
vincible. They require proper care and handling
to achieve the normal service life of 300 - 600
hours. If the hoses are abused, the service life
will be much shorter.
Stretched or abused hose can fail prematurely
and unexpectedly, which could cause injury to
personnel. Hoses that have been exposed to
excessive stretching or kinks should be removed
from service and discarded.
Hoses Present Tripping Hazards
Be careful to layout the hoses to reduce risk of
entanglement and tripping.
Check Connections
Check the condition of the connection threads
prior to connecting any ttings or hoses. Use an
anti-seize compound on all ttings and hoses
to prevent “galling,” as galling will destroy the
threads, ttings and/or hose ends.
Tighten Connections
Properly tighten all high pressure connections.
Usually, snug plus a 15% tightening will properly
seal connections.
Take Proper Care of Your Hose
A) Protect the hose from contact with sharp
objects, abrasive surfaces and foot or wheel
trac.
B) Never subject Ultra-High Pressure hose to a
tight radius (less than 30” (.8 m) or pull on a
coiled hose. Always make sure the hoses are
straight with no coils before pulling on the hose
to deploy it.
C) Never pull hard on an Ultra-High Pressure hose
or expose the hose to heavy loads like drag-
ging equipment or deploying long lengths of
hose. This can stretch the hose and weaken
it. Never pull more than 25 feet of hose by a
coupler or tting. Always move long lengths
of hose by the hose itself to keep the strain
o the ttings.
D) When using a tractor or a hog tool, always op-
erate the equipment well within the maximum
distance to avoid straining or damaging hoses.
Check Burst Rating
Do not use an Ultra-High Pressure hose that does
not have a listed burst rating or with a burst rating
of less than 60,000 PSI (4,137 BAR).
Retire Hose from Service if:
A) Cover is damaged and reinforcing wires are
exposed to rust and corrosion.
B) Cover is loose and/or has blisters or bulges.
C) Hose has been crushed or kinked.
D) End tting shows evidence of damage, slippage
or leakage.
E) Hose has been exposed to pressures of 2 times
the operating pressure.
F) Hose has been stressed or stretched.
Check Dump Valve Water Hose
Any hose used for returning dumped water back
to the pump or vacuum line must have a large
enough diameter and psi strength so that poten-
tially dangerous release pressure is allowed full
ow and release pressure is contained safely. Keep
hose in good condition.
1.4 High Pressure Fitting Safety
Fitting Ratings
Use high pressure ttings with a rating of 60,000
psi (4137 BAR.)
Check Fittings
Do not use ttings that have been cross threaded
or have damaged threads.
Fitting Connections
Use anti-seize compound on all hose and tting
connections to prevent galling. Do NOT apply
anti-seize to the seating area of any connections.

Section 1 - Safety Information
DANGER
AN INJURY CAUSED BY HIGH PRESSURE WATERJETS CAN BE SERIOUS. YOU
SHOULD READ THIS WARNING STATEMENT CAREFULLYANDALWAYS CARY THE
MEDICAL INFORMATION CARD WITH YOU.
• IN THE EVENT OF ANY WATERJET INJURY:
• SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT DELAY.
• INFORM THE DOCTOR OF THE CAUSE OF THE INJURY.
• SHOW THE DOCTOR THE MEDICAL INFORMATION CARD OR THIS WARNING
STATEMENT AND NOTE TO PHYSICIAN BELOW.
• TELL THE PHYSICIAN WHAT TYPE OF WATERJET PROJECT WAS BEING
PERFORMEDAT THETIME OFTHEACCIDENTAND THESOURCE OFTHE WATER.
MEDICAL ALERT
NOTE TO PHYSICIAN
This patient may be suering from a waterjet injury. Evaluation and
management should parallel that of a gunshot injury. The external mani-
festations of the injury cannot be used to predict the extent of internal
damage. Initial management should include stabilization and a thorough
neurovascular examination. X-rays can be used to asses subcutaneous
air and foreign bodies distant from the site of the injury. Injuries to ex-
tremities can involve extensive nerve, muscle, vessel damage as well as
cause a distal compartment syndrome. Injuries to the torso can involve
internal organ damage. Surgical consultation should be obtained. Ag-
gressive irrigation and debridement is recommended. Surgical decom-
pression and exploration may also be necessary. Angiographic studies
are recommended preoperatively if arterial injury is suspected. Bandages
with a hygroscopic solution (mgso4 ) and hyperbaric oxygen treatment
have been used as adjunctive therapy to decrease pain, edema and sub-
cutaneous emphysema. Unusual infections with uncommon organisms
in immunocompetent patients have been seen; the source of the water is
important in deciding on initial, empiric antibiotic treatment, and broad-
spectrum intravenous antibiotics should be administered. Cultures should
be obtained.

2.1 HT1000 Overview
The Ground Hog is a walk behind, Ultra High Pres-
sure waterblasting tool equipped with a rotating
spray bar. High pressure water, vacuum and hy-
draulic oil pressure is supplied by an Ultra High
Pressure (UHP) water pump, vacuum blower and
hydraulic system on a Waterblasting truck, skid
unit or customer supplied, remote power system.
Hydraulic pressure hydraulic uid that rotates the
spray bar and UHP water ow are turned ON and
OFF by control levers on the Ground Hog handle.
Switches in the control levers are connected to
electric solenoid valves on the power system that
control the ow of pressurized hydraulic uid to
the spray bar thru-shaft motor and the valve that
turns high pressure water ON and OFF.
The Ground Hog is designed for operating pres-
sures of up to 40,000 psi (2,758 bar) and to be
directly connected to the accessory ports on the
Waterblasting truck, trailer or skid mounted unit.
If the Ground Hog is connected to a non Water-
blasting power system that includes a hydraulic
system, the unit must be equipped with a hydraulic
manifold and a 12 or 24 volt electrical system
with a harness and electric solenoids designed to
be used with Waterblasting handheld Hog Tools.

2.2 Hog Head
Overview
The Hog Head is a single blasting head design
mounted on the Ground Hog chassis. Front and
rear castor wheels support the head at a preset
height to prevent the spray bar from contacting
the pavement.
The term “Stando” refers to the height of the
spray bar above the pavement. The stando dis-
tance is set by adjusting the wheels that support
the Hog Head. Stando directly aects removal
performance and should be checked periodically
and adjusted as required.
The factory preset stando distance is 1.5” (3.5
cm) from the spray bar to the pavement. Spacers
on each front caster adjust the height of the Hog
Head. Adjustment may be required to maintain
proper clearance by adding spacers as the castor
wheels wear.
Large wing nuts on the caster support arms allow
the caster assemblies to be rotated in and out.
Caster assemblies can be rotated parallel to the
handle to reduce the width of the Ground Hog for
storage or to allow the Hog Head to get closer to
curbs and walls. Move the caster assemblies out
to a 45 degree angle to provide maximum stability
for most operating situations. Make sure to tighten
the wing nuts securely once the caster assemblies
are in the desired position.
High pressure water from the power system is
supplied by the UHP hose connected to a special
tting at the top of the thru-shaft hydraulic motor.
The center of the rotating shaft is drilled to allow
high pressure water to pass through the motor
shaft to the spray bar. A special swivel seal as-
sembly provides a positive seal for the connection
to the high pressure hose while allowing the thru-
shaft to turn freely. A brass button seal provides
a positive seal for the spray bar to thru-shaft
connection.
The Hog Head design allows the operator to choose
several dierent length spray bars for specic
removal widths. The operator can choose spray
bar rotation speeds between 700 and 3000 RPM
using the adjustable control valve on the Ground
Hog handle.
