1.1 General Safety
Use Professional Training
Operating high pressure waterblasting equipment
requires professional training, including safe work
practices and procedures. Only professionally
trained personnel should be allowed to setup,
operate, or maintain high pressure waterblast-
ing 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 pres-
sure 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 equipment opera-
tion manuals and instructions prior to using any
Hog Technologies product. Contact Hog Technolo-
gies (877-HOG ROAD) should any questions arise.
Major Component Operation Manuals
The suppliers of some major components such
as truck chassis, tractors, engines, pumps, and
drive units, provide their own operation manuals
which have been included with your equipment.
You should read the information in this manual
and the manuals of other manufacturers com-
pletely 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 WATERBLASTING 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.
Always use eye protection to shield from projected
debris. Use ear protection to protect from noise
levels generated from pump, vacuum and water-
blasting heads. It is very important to wear steel
toed boots that provide good traction on slippery
surfaces such as on top of water and debris tanks.
Never wear loose clothing. Loose clothing can get
caught on moving or rotating parts causing serious
injury or even death.
Most ultra-high pressure waterblasting opera-
tions generate noise levels above 90 dB. Hearing
protection 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 SOTHAT 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 WORKAREATHAT CAN CAUSE SEVERE
INJURY. MAKE SURE ALL PERSONNEL STAY CLEAR OF
THE BLASTING AREAAND USE HARD HATS, EYE AND EAR
PROTECTION.

12
Section 1 - Safety Information
Always be sure your work area is clear of people
whenever the ultra-high pressure pump is en-
gaged. When working on the waterblasting head
with an operator in the cab of the truck you should
always make sure you can see his hands.
Use Only Products Intended for High
Pressure waterblasting Use
Know the pressure ratings of all equipment be-
ing used and never exceed the service rating of
the weakest component. This system is designed
to work with pressures up to but not exceed-
ing 40,000 psi (2758 bar). Ultra-High Pressure
replacement parts must have a stated minimum
burst rating of 1.5 times the maximum operat-
ing pressure. All equipment pressure rating and
warning tags should be left intact.

Never Alter a Hog Technologies Product
Do not alter any product without written consent
from the manufacturer. Any alterations could have
serious consequences including bodily harm or
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:
YOUR 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
The water and vacuum systems, hoses and the
waterblasting head should be drained of all wa-
ter or lled with an antifreeze solution. For the
40K pump system, refer to pump manufacturer’s
procedures for maintaining equipment in freez-
ing climates. If the unit is operated in freezing
temperatures or even temperatures below 60
degrees Fahrenheit, it is necessary to operate the
system with the high pressure pump engaged and
the engine set at IDLE speed only, until the oil
temperature rises above 60 degrees Fahrenheit.
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 (DUMP VALVE
40K) switch.
WARNING
INJURIES FROM ULTRA-HIGH PRESSURE WATERBLASTING
ARE VERY SERIOUS AND CAN RESULT IN A FATALITY.
ALWAYS MAKE SURE ALL PERSONNEL ARE A SAFE
DISTANCE FROM THE WORKAREABEFORE THE PRESSURE
PUMPISENGAGED. NEVER PUTHANDS, FEETOR ANYPART
OF YOUR BODYIN OR NEAR THE HIGH PRESSURE STREAM.
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.

13
Section 1 - Safety Information
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 Waterblasting Heads
Check blasting heads for smooth and proper
operation before each shift. Do not use equipment
that has not been checked thoroughly.
Check Control Components
Check all switches and control panel devices to
ensure each is working properly before beginning
operations. Do not use equipment if any device is
malfunctioning.
Use Safety Protection
Always use eye protection to protect eyes from
projected debris. Use ear protection to protect
from noise levels generated from pump, vacuum
and waterblasting operations.
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.
Know Your Surroundings
Always be aware of, and pay attention to your
surroundings. – i.e. - truck, 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 bars,
connections or nozzles. Should any repairs or ad-
justments be necessary, disengage the pump to
relieve all pressure before making any required
repairs or adjustments.
CAUTION
TOAVOID POSSIBLE INJURYAND DAMAGE TO EQUIPMENT,
USE ONLY THOROUGHLY TRAINED PERSONNEL TO
PERFORM MAINTENANCE OR REPAIRS. ALWAYS TEST ALL
COMPONENTS AT LOW PRESSURE.
Start at Low Pressure
Always start blasting with the system at low
pressure (low RPM) and slowly increase RPM to
operating pressure. Engage and disengage 40K
switch two times at operating pressure to check
the operation of the blasting head and dump 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 40K STOP
switch is pressed. 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 to the dump valve.
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 Stopped
Always make sure Ultra-High Pressure is dis-
engaged before forward or reverse motion is
stopped. Damage to road surface will occur if
blasting continues when the truck is brought to
a stop.

14
Section 1 - Safety Information
WARNING
MOST HIGH PRESSURE WATERBLASTING OPERATIONS
PRODUCE NOISE LEVELS THAT EXCEED90 DB WHICH CAN
CAUSE PERMANENT HEARING LOSS.
ALL OPERATORS AND SUPPORT PERSONNEL MUST
WEAR EAR PROTECTION IN ACCORDANCE WITH OSHA
STANDARDS AND PROVISIONS SHOULD BE MADE FOR
REGULAR INSPECTION AND MAINTENANCE.
REMEMBER: ULTRA-HIGH PRESSURE BLASTING CAN
CAUSE DEBRIS TO BE PROJECTED UNEXPECTEDLY IN
ANDAROUND THE WORKAREATHAT CAN CAUSE SEVERE
INJURY. MAKE SURE ALL PERSONNEL STAY WELL CLEAR
OF THE BLASTING AREA AND USE HARD HATS, EYE AND
EAR PROTECTION.
1.3 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.
1.4 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.
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.

15
Section 1 - Safety Information
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.
1.5 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.
1.6 Dumping Safety
A) Always drain all the liquid from the debris
tank before dumping the solids.
B) Always dump on level ground, never uneven
or sloped ground.
C) Always choose solid ground, not soft sand or
wet soil.
D) Always use the remote control to tilt the
tank.
E) Make sure the operator and all personnel are
well clear of the truck before tilting the tank.
F) Never allow personnel under a raised tank
without safety supports in place.
G) Always be careful to avoid any pinch points
which could cause injury.

AN INJURY CAUSED BY HIGH PRESSURE WATERJETS CAN BE SERIOUS. YOU
SHOULD READ THIS WARNING STATEMENT CAREFULLYANDALWAYS CARYTHE
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 THE TIME OF THEACCIDENTAND THE SOURCE OF THE 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 distant from the site of the injury. Injuries to extremities
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. Aggressive
irrigation and debridement is recommended. Surgical decompression
and exploration may also be necessary. Angiographic studies are recom-
mended 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 subcutaneous
emphysema. Unusual infections with uncommon organisms in immuno-
competent 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 ob-
tained.

2.1 Stripe Hog System Introduction
The SH7500 waterblasting system is mounted to
the truck chassis and powered by the truck engine
through a transmission PTO and a gearbox PTO.
The waterblasting system includes an Ultra-high
pressure water system, vacuum system, water
and debris tanks, hydraulic system, hydrostatic
drive system and DC electrical system.
Most components are controlled by switches in the
cab mounted control panel and Joystick. Others
are controlled by switches in the remote control
or switch panels located on the chassis.
The systems also supports the connection of
the optional HT1000 Ground Hog when the job
requires the extended reach and/or additional
maneuverability.
The operation and maintenance requirements for
the engine, drive train and chassis components
are unique to the manufacturer and the selected
options. Each truck chassis manufacturer provides
owners information manuals with their product.
It is important that you read the manuals care-
fully and become familiar with the proper care
and operation of engine, drive system, chassis,
safety equipment and all components of your
truck chassis.

2.2 Ultra-high Pressure Water System
The ultra high waterblasting system consists of
two water storage tanks, charge pump, Ultra-
High Pressure (UHP) pump, high pressure hoses
and the Hog Head. Switches and the joystick in
the control panel enable the operator to control
all aspects of the high pressure blasting system
from the cab of the truck.
Each manufacturer of the high pressure water-
blasting system components provides an informa-
tion and operating manual with its product. It is
extremely important that you read the manuals
and become familiar with the proper care and
operation of the components before operating the
waterblasting system.
WARNING
HIGH PRESSURE WATER FROM SPRAY JETS OR RUPTURED
HOSES CAN CAUSE SEVERE INJURY OR EVEN DEATH.
ALWAYS BE SURE WORK AREA IS CLEAR OF PEOPLE,
HANDS, FEET, ETC., BEFORE ENGAGING THE DUMP VALVE
40K SWITCH TO ACTIVATE THE ULTRA-HIGH PRESSURE
SYSTEM.
Clean Water Tank
The clean water tanks are mounted to the chas-
sis just forward of the debris tank and made of
plastic to reduce corrosion and provide a supply
of clean, fresh water to the charge pump. A site
tube on the side of the forward tank indicates the
water level and a valve on the passenger side, just
below the tank allows for quick draining.
An optional hose and quick connect coupler at
the rear of the truck provides a connection to an
optional trailer mounted water tank to provide
additional water which dramatically increases
working time between rells. A three-way valve
in the intake hose allows the operator to select to
use the trailer tank, main tanks or the truck and
trailer tanks simultaneously. To avoid water sup-
ply problems to the charge water and UHP pumps,
always make sure the valve is set to the desired
position before waterblasting operations begin.

1919
Section 2 - Stripe Hog Systems
Note:
If your truck is equipped with the optional
trailer mounted water tank, it is important
that the three-way valve be set to select only
the main tanks when not using the trailer
mounted tank. If the valve is set to select
the trailer tank or to use the truck and trailer
tanks simultaneously, the charge pump will
suck air and not provide water to the UHP
pump. This can cause severe damage to
both pumps.
The clean water ll connection accommodates
large hoses that are typically connected to a me-
tered source like a re hydrant to expedite the
lling of the tank. Operators must always monitor
the tank closely during lling operations as the
ow of water from a hydrant will be greater than
the ow capacity of tank air vent. Overlling the
tank will cause excessive pressure and damage
the tank.

Section 2 - Stripe Hog Systems
Only use potable water (clean enough to drink)
to increase the service life of the components in
the Ultra-High Pressure system. Always ush the
water source for several minutes prior to lling
the tank to help ensure that no debris enters the
system. Additionally, the tank should be ushed
frequently with clean, fresh water to prevent the
accumulation of debris that may accidently enter
the tank.
There is a 3” ball valve on the passenger side
bottom of the tank that allows for quick draining
of the tanks when ushing is required and com-
plete draining for system winterization. Another
3” valve on the passenger side provides drainage
for the wastewater bladder in the rear clean water
tank. A large man-way hatch on the top of each
tank provides access to the interior of the tank or
wastewater bladder for inspection or to facilitate
cleaning.
Remember that the wastewater bladder displaces
clean water in the tank as it lls, causing the site
gauge to show more water than is actually in
the tanks. The site gauge is intended to provide
an accurate indication of the water level during
lling operations only. It is not a reliable level
indicator during operation when the debris tank
transfer pump is being used to collect recovered
wastewater.
Use actual blasting time during operation with an
average pump consumption of 8-9 gallons (30-34
liters) per minute to estimate the remaining clean
water in the tank. To ensure maximum clean water
volume, always completely drain the wastewater
bladder before lling the clean water tank.
