Section 2 - Stripe Hog Systems
When replacing or connecting fittings or hoses
always inspect the threads and use an anti-seize
compound on all threads to prevent “galling.”
(Refer to the High pressure hose installation pro-
cedure in the Maintenance section of this manual).
Galling is the term for thread damage that occurs
from heat buildup in the threads of stainless steel
fittings. This will destroy the threads and cold
weld the fittings together before they are tight.
To prevent system contamination, do not get
anti-seize on the seat area of any high pressure
water fitting. Always inspect and test the system
with the blasting head up following repairs or at
the start of each shift by operating the system at
low pressure. Then slowly bring the equipment up
to operating pressure while carefully monitoring
the replaced components for any leaks. If a leak
is detected, pressure down the system, tighten
the fitting or hose and then check again until no
leaks are detected.
WARNING
HIGH PRESSURE WATER FROM NOZZLES OR RUPTURED
HOSES CAN CAUSE SEVERE INJURY. ALWAYS MAKE SURE
TO CHECK YOUR WORK AREA TO ENSURE IT IS CLEAR OF
PEOPLE BEFORE ACTIVATING THE PTO, CHARGE PUMP AND
DUMP VALVE 40K SWITCHES TO ACTIVATE THE ULTRA-HIGH
PRESSURE SYSTEM.
WARNING
REFER TO THE GENERAL SAFETY SECTION OF THIS
MANUAL FOR A LIST OF PRECAUTIONS TO BE OBSERVED
WHEN OPERATING OR SERVICING ULTRA-HIGH PRESSURE
EQUIPMENT. USE ONLY THOROUGHLY TRAINED PERSONNEL
TO PERFORM MAINTENANCE OR REPAIRS ON THE HIGH
PRESSURE SYSTEM.
Take proper care of your hoses:
A) Protect the ultra-high pressure hose from
contact with sharp objects, abrasive surfaces,
foot and/or wheel traffic.
B) Never subject an ultra-high pressure hose to
a coil diameter less than 10” (.25 m) or pull
on a coiled hose. Always make sure the hose
is 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. Never pull more than 25 feet of hose by
a coupler or fitting. Always move long lengths
of hose by the hose itself to keep the strain
off the fittings.
WARNING
H I G H P R E S S U R E H O S E S O F I N F E R I O R Q U A L I T Y O R
OF A LOWER PRESSURE RATING THAN SPECIFIED BY
H O G T E C H N O L O G I E S C A N R E S U LT I N D A M A G E TO
EQUIPMENT AND/OR SEVERE INJURY TO PERSONNEL.
NEVER USE REPLACEMENT HOSES WITH UNKNOWN
PRESSURE RATINGS OR RATED LESS THAN REQUIRED
SPECIFICATIONS.
WHEN REPLACING DAMAGED OR WORN HOSES YOU
SHOULD ONLY USE HIGH PRESSURE HOSES PURCHASED
F R O M H O G T E C H N O L O G I E S W I T H A N O P E R AT I N G
PRESSURE RATING OF AT LEAST 40,000 PSI (2758 BAR.)
THESE HOSES ARE DIFFICULT TO FIND. YOU SHOULD
ALWAYS KEEP SPARES ON THE TRUCK AS SUGGESTED IN
THE SPARE PARTS SYSTEM.
Retire hose from service if:
A) Cover is damaged and reinforcing wires are
exposed to rust and corrosion.
B) End fitting shows evidence of damage or is
leaking.
C) Hose has been kinked, crushed, stretched or
coiled tighter than the minimum bend radius.
