Section 1:
Safety Information
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 blast-
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 water blasting
equipment operation manuals and instructions
prior to using any Hog Technologies product. Con-
tact Hog Technologies (877-HOG ROAD) should
any questions arise.
Major Component Operation Manuals
The suppliers of some major components such
as trailer axles, engines and pumps, 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 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.
Always 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 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 water blasting 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 PROTECTIONSO 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 WORKAREA THAT CAN CAUSE SEVERE
INJURY. MAKE SURE ALL PERSONNEL STAY CLEAR OF
THE BLASTING AREAAND USE HARD HATS, EYE AND EAR
PROTECTION.

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 water blasting head
or other high pressure components, always make
sure the high pressure system and trailer engine
are shutdown.
Use Only Products Intended for High
Pressure water blasting 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 exceeding
40,000 psi (2758 bar). ultra-high pressure system
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.

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 AN
INTERNAL COMBUSTION ENGINE 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
MAINTENANCEPROCEDURESARENECESSARYTOENSURE
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
water blasting 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
switch.
WARNING
INJURIES FROM ULTRA-HIGH PRESSURE SYSTEM WATER
BLASTING ARE VERY SERIOUS AND CAN RESULT IN A
FATALITY. ALWAYS MAKE SURE ALL PERSONNEL ARE
A SAFE DISTANCE FROM THE WORK AREA BEFORE THE
PRESSURE PUMP IS ENGAGED. NEVER PUT HANDS, FEET
OR ANY PART OF YOUR BODY IN 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 Water Blasting head
Check blasting head 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 water blasting operations.
WARNING
ULTRA-HIGH PRESSURE SYSTEM 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 sur-
roundings, i.e., the trailer, hoses, people, walls,
moving vehicles, live lanes of trac, etc.
Test System
With the spray bar and high cohesive nozzles
installed and the blasting head raised, operate
the pump at low pressure to check for nozzle
accuracy and leaks in spray bars, connections or
nozzles. Should any repairs or adjustments be
necessary, disengage the pump and shutdown the
high pressure system and trailer engine 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 TESTALL
COMPONENTS AT LOW PRESSURE.
Start at Low Pressure
Always start blasting with the system at low pres-
sure (low RPM) and slowly increase RPM to oper-
ating pressure. Engage and disengage the DUMP
VALVE 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 switch
turned o. If this does not relieve system pressure
immediately to below 100 psi (7 bar), 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,
relieve the pressure in the system and shutdown
the trailer engine before attempting any repair.
Always follow manufacturer’s repair instructions.
Never Blast When Stopped
Always make sure ultra-high pressure system
is disengaged before forward or reverse motion
is stopped. Damage to road surface will occur
if blasting continues when the blasting head is
brought to a stop.

14
Section 1 - Safety Information
WARNING
MOST HIGH PRESSURE WATER BLASTING 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 SYSTEM 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 system hoses are tough, but
not invincible. They require proper care and han-
dling 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 system 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
system hose or expose the hose to heavy
loads like dragging 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 system 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, slip-
page 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 clean water tank must have a
large enough diameter and psi strength so that
potentially 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 trailer 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.
1.7 Trailering Safety
A. The tow vehicle must be rated for the expected
trailer and tongue weight.
B. Check trailer tire air pressure.
C. Make sure the hitch is latched and locked.
D. Connect and test trailer lights.
E. Make sure the safety chains are crossed and
connected.
F. Test the trailer brakes for proper operation.
G. Empty the clean water tank and waste water
bladder before trailering on the highway when
possible to reduce trailer weight.

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 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

2.1 Stripe Hog System Introduction
Introduction
The SK2000 water blasting system is mounted
to the trailer chassis and powered by an onboard
diesel engine and a belt driven hydraulic pump.
The water blasting system includes an ultra-high
pressure water system, vacuum system, water
tank with an integrated wastewater bladder, hy-
draulic system and a DC electrical system.
Most components are controlled by switches in
control panels mounted on the front of the trailer.
Dumping and other operations are controlled by
a removable remote switch panel connected to a
plug on the chassis. Quick connect hydraulic hose
connectors and a 12 volt DC plug is provided to
connect the optional HT1000 Ground Hog, HT2500
Hog Rider or other Hog Tools to the water blast-
ing system.
The operation and maintenance requirements for
the engine are unique to the manufacturer. Each
major component of the power unit and water
blasting system provides an owners information
manual with their product. It is important that you
read the manuals carefully and become familiar
with the proper care and operation of the engine,
water blasting system and related components.

2.2 Trailer Chassis
The waterblasting system is mounted to a heavy
duty trailer with a welded galvanized steel frame,
tandom torsion axles, pintle style coupler, brakes,
lights and a tongue jack.
The trailer weighs 12,000 lbs (5443 kg) with
empty fuel and water tanks and 17,000 (7711
kg) to 18,000 lbs (8165 kg)when the tanks are
full. Tongue weight is 2,700 (1225 kg) with
empty tanks and 3,500 lbs (1588 kg) when they
are full. Make sure your vehicle is rated to handle
the tongue and gross vehicle weight of the trailer.
Pintle Hitch
The standard pintle coupler is bolted to a bracket
on the front of the trailer. Bolt holes in the bracket
allow the coupler to be moved up or down to ac-
commodate a variety of tow vehicle hitch heights.
Trailer Jack
A swivel mounted jack on the side of the trailer
frame raises or lowers the trailer coupler. A pin
on the swivel mount is removed to swivel the jack
down for use and up for travel. Insert the pin with
the jack in the up or down position to secure the
jack in the selected position.
Trailer Lights
All trailers are equipped with side marker and
tail lights that are connected to the tow vehicle.
Always test the lights to make sure they are op-
erating properly whenever the trailer is connected
to the tow vehicle.
Electric Brakes
Each axle is equipped with electric brakes acti-
vated by a brake controller in the cap of the tow
vehicle. The controller applies the trailer brakes
whenever the tow vehicle brakes are activated.
The controller senses the tow vehicle deceleration
rate and activates the trailer brakes in proportion
to the vehicles braking action.

Trailer Break-Away System
The system includes a break-away system with
a cable tether attached to the tow vehicle and
the break-away switch that automatically applies
the trailer brakes and stop the trailer if it should
accidently disconnect from the tow vehicle while
driving. The system includes a separate battery
charged by the vehicle that provides electrical
power to the brake actuators at each wheel if the
trailer disconnects while towing.
A test button and LED status lights show the con-
dition of the battery. You should always press the
test button to check the status of the break-away
system battery each time the trailer is attached
to the tow vehicle.
2.3 Ground Hog Landing Pad
The Ground Hog is typically stored and transported
on a special landing pad on the trailer chassis. The
pad is equipped with a ramp and tie down bracket
for easy loading and to secure the Ground Hog
for transport.
Spring loaded safety pins on each side of the ramp
secure it in the stored position. It is lowered for
loading and unloading by removing the pins and
lowering the ramp until is resting on the pave-
ment. The tie down bracket is hinged and secured
with a spring loaded safety pin.
Refer to the Water Blasting Operation section for
instructions to load and unload the Ground Hog.

Typical Trailer Engine
2.4 Trailer Mounted Trailer Engine
The ultra-high pressure system pump is powered
by the onboard auxiliary diesel engine. The vacuum
system, charge water pump and all other hydrauli-
cally powered systems are powered by a hydraulic
pump connected to the engine by a pulley and belt
drive system. An electronic engine control panel
at the front of the trailer provides complete con-
trol of the engine. It also monitors critical engine
systems and provides warnings and/or automatic
shutdown to prevent costly engine repairs in the
event a critical engine function fails.
A tank mounted on the forward trailer chassis
provides fuel for the engine. A digital gauge in
the engine control panel monitors fuel ow to the
engine and total gallons consumed. Some tanks
are also equipped with a fuel level gauge. The fuel
tank should be lled at the start of each shift.
The engine and water blasting system DC electrical
system is equipped with onboard batteries, circuit
protection and charging system. Refer to the Elec-
trical System section for additional information on
the engine and water blasting electrical system.
The ultra-high pressure (UHP) system pump is
directly driven by the trailer engine. The pump is
mounted to a reduction gear case that reduces the
output shaft RPM to between 500-600 RPM, which
is the operating range for the pump. A exible cou-
pler between the engine and pump reduces vibra-
tion and reduces the possibility of engine damage
from a catastrophic pump failure. The gear case
is equipped with a site glass to monitor oil level.
Refer to the Scheduled Maintenance section for
addition information on the reduction gear case.
The engine should be started only when the Stripe
Hog is on the job site and ready to go to work. Al-
ways check the uid levels and all systems before
starting the engine.
Trailer engine Throttle Control
The operator uses the hare/turtle throttle switch on
the engine control panel to set the engine speed for
the desired water blasting pressure and vacuum.
Press and hold the top (hare) of the throttle rocker
switch to increase engine speed. Press and hold
the bottom (turtle) of the rocker switch to decrease
engine speed.
The engine remains at the selected engine speed
until it is increased or deceased by the operator us-
Trailer engine Control Panel
ing throttle switch. Consequently, when the DUMP
VALVE switch is turned o, the engine RPM remains
at the preset speed. This allows the water blasting
system to develop full pressure immediately when
the DUMP VALVE switch is turned on.
When blasting operations are complete, press the
bottom (turtle) of the switch to reduce engine
speed to idle before shutting down the engine.
