Safety Information
WARNING
Start at Low Pressure
Always start blasting with the system at low
pressure slowly increasing to operating pressure.
Engage and disengage Ultra High Pressure (40 K)
switch two times at operating pressure to check
operation of Hog Head before starting blasting
operations.
Check Your Stripe Hog Dumping Pressure
When setting pressure ALWAYS ensure that the
system pressure drops to less than 100 PSI (7
Bar) immediately when 40 K switch is turned
OFF. If this does not relieve system pressure im-
mediately to below 100 PSI when turned off, do
not use the equipment until repairs are made to
the dump valve.
Know Your Surroundings
Know your surroundings well – i.e. - truck, hoses,
people, walls, moving vehicles, live lanes of traf-
fic, etc.
Never Blast When Stopped
Always make sure 40 K switch is OFF BEFORE
forward or reverse motion is stopped. Damage to
road surface will occur if blasting continues when
a Stripe Hog is brought to a stop.
MOST HIGH PRESSURE wATERBLASTING OPERATIONS
PRODUcE NOISE LEVELS THAT EXcEED 90 DB wHIcH cAN
cAUSE PERMANENT HEARING LOSS.
ALL OPERATORS AND SUPPORT PERSONNEL MUST wEAR EAR
PROTEcTION IN AccORDANcE wITH OSHA STANDARDS AND
PROVISION SHOULD BE MADE FOR REGULAR INSPEcTION
AND MAINTENANcE.
ALL PERSONNEL EXPOSED TO 90 DB OR GREATER NOISE
LEVELS SHOULD REcEIVE INSTRUcTION IN THE cORREcT
USE OF EAR PROTEcTION SO 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 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.
1.3 Nozzle Safety
Check Flow Rating
Nozzles combined flow rating must be compatible
with the pump discharge and pressure rating. Re -
fer to your nozzle flow rating chart in this section.
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 Orifices
Prior to installation, make sure the nozzles have
no clogged orifices. 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.
Connect Nozzle
Insert the nozzle into blasting head finger tight.
Using a 3/8” socket or box end wrench, tighten
the nozzle about 15% more. In some situations,
it may be necessary to tighten additionally. Be
certain the nozzle seat in the blasting head is in
good condition. If it is damaged, replace with a
new blasting head.
