Safety Information
1.1 General Safety
Use Safety Training
Only trained personnel should be allowed to setup,
operate, or maintain this equipment. Water blast
operators should be made aware that the water
jet nozzles can cause serious bodily injury. Train-
ing supervisors should demonstrate the powerful
potential damage of the nozzles by showing new
trainees the eect of water jets cutting a piece
of 2 x 4 wood.
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.
Work Area Safety
Remember, safety is rst! Only set up to work
in areas properly protected from trac and other
hazards. Always barricade the work area and post
signs warning personnel of the hazards associated
with high pressure waterblasting operations.
Outt all operators with proper safety apparel.
Steel toed, non-skid boots, hard hats with safety
shields or safety glasses, gloves, ear protection,
etc.
Most ultra high pressure waterblasting opera-
tions generate noise levels above 90 db. Hearing
protection is required in accordance with OSHA
standards.
Use Only Products Intended for High
Pressure Waterblasting Use
Know the pressure ratings of all equipment being
used and never exceed any operating pressure
higher than the rating of the weakest component.
This system is designed to work with pressures
up to but not exceeding 40,000 PSI (2,758 Bar).
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.
Always Read Instructions
Read and follow all the manufacturer’s instructions
prior to using any Hog Technologies product. Con-
tact Hog Technologies should any questions arise.
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.
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 pre-
vent “galling,” as galling will destroy the threads
and essentially the ttings and/or hose ends.
Tighten Connections
Properly tighten all high pressure connections.
Usually, snug plus a 15% tightening will properly
seal connections.
Purge System
Before attaching accessories to the high pressure
hoses, engage pump at low speed to purge the
system. Any dirt or debris in the system can clog
nozzle orice’s and cause system pressure to spike
excessively causing damage to components.
Test System
With the Waterblasting tools properly attached and
equipped with proper high cohesive nozzles, oper-
ate the pump at low pressure to check for nozzle
accuracy and leaks on spray bar, spray head, spray
bar or nozzles. Should any repairs or adjustments
be necessary, disengage the pump and shutdown
all engines to relieve all pressure before making
any required repairs or adjustments.
Set System Pressure
With system operating properly, set your pressure
according to methods described by pump manu-
facturers instructions. Refer to the pump oper-
ating manual for specications and instructions.
Use the Minimum Pressure Required
Do not exceed the operating pressure of the
system’s lowest pressure-rated component. All
equipment 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,
