rotation speed dial is set to 0 so the spray bar
does not rotate. Staying well clear of the water
jets, no closer than 18”, visually inspect the spray
pattern of each nozzle. If the spray is tight with
a cohesive stream for 1/2 -1 1/2 inches from the
nozzle, it rates as grade 4 or better (Refer to the
Nozzle Quality Guide in this section of the manual)
and it is good.
DANGER
THE HIGH PRESSURE STREAM FROM THE SPRAY NOZZLES
CAN CAUSE SEVERE INJURY OR DEATH IF IT COMES IN
CONTACT WITH HANDS, FEET OR ANY PART OF A PERSON’S
BODY. IT CAN ALSO PROJECT LOOSE DEBRIS IN THE
AREA OF THE HOG HEAD WITH ENOUGH FORCE TO CAUSE
SERIOUS INJURY, PARTICULARLY TO THE EYES. HIGH
PRESSURE WATER CAN TEAR OFF SKIN AND INJECT WATER
DIRECTLY INTO THE BLOOD STREAM WHICH CAN BE FATAL.
ALWAYS DEACTIVATE THE HIGH PRESSURE SYSTEM BEFORE
RAISING THE HOG HEAD AND MAKE SURE THE AREA IS
CLEAR OF PEOPLE, HANDS AND FEET BEFORE ENGAGING
THE CHARGE WATER, PTO AND DUMP VALVE SWITCHES
TO ACTIVATE THE HIGH PRESSURE SYSTEM TO TEST AND
INSPECT THE NOZZLES WITH THE HOG HEAD RAISED.
If a nozzle rates as a 5 or higher on the Nozzle
Quality Chart, it is worn or damaged and must be
replaced. Nozzle replacement is easy and doesn’t
take much time. Refer to the nozzle replacement
procedure in the Maintenance section of this man-
ual for detailed instructions for replacing nozzles.
Nozzles typically last 12-16 hours of blast time,
however, you can experience shorter or longer
nozzle life, depending on the source and quality of
water being used. Any dirt or debris in the system
can clog a nozzle orifice causing a spike in the high
pressure system which will rupture the burst discs
and could cause damage to components.
NOTICE:
NOZZLES MUST ALWAYS BE CHECKED WITH THE SPRAY
BAR PROTECTOR REMOVED TO AVOID INACCURATE
READINGS. START THE PUMP AT LOW PRESSURE AND
SLOWLY INCREASE TO OPERATING PRESSURE TO CHECK
NOZZLE QUALITY AND FOR LEAKS ON THE SPRAY BAR,
NOZZLES AND HOSES. SHUTDOWN THE WATERBLASTING

You can select different nozzle sizes in a variety of
spray bar configurations to accommodate the ma

terial to be removed and the type of substrate. The
Nozzle Quality Guide in this section and Spray Bar
Configuration Diagrams located in the Waterblast
-
ing Operation section will provide assistance in
choosing the right nozzle configurations for most
removal applications. The number of nozzles in a
spray bar should be considered in every removal
