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 orifices and cause
system pressure to spike excessively, causing
damage to components.
Check Water Blasting 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 water blasting 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 traffic, 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
TO AvOID POSSIBLE INJURY AND DAMAGE TO EqUIPMENT,
U S E O N LY T H O R O U G H LY T R A I N E D P E R S O N N E L 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 specifications 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.
