High Pressure Nozzles and Spray Bars
Each nozzle delivers a stream of water at ex-
tremely high pressure. The size and intensity of
the stream is determined by orifice size in the
nozzle. The performance ranges from least ag-
gressive to most aggressive.
Nozzles typically last 12-16 hours of blast time,
however, you could experience shorter or longer
nozzle life, depending on the type of surface be-
ing blasted. They should be inspected before the
start of each shift or when the operator notices a
change in performance while waterblasting.
Nozzles are easy to replace and different nozzle
sizes in a variety of spray bar configurations can
be selected to accommodate the material to be re-
moved and the type of substrate. The nozzle flow

chart and spray bar configuration diagrams located
in the Safety Information section and Appendix C
will provide assistance in choosing the best nozzles
for the job. As the operator becomes more expe-
rienced, nozzle selection becomes easier. You can
also contact Hog Technologies Customer Service
for assistance in selecting the proper spray bar
and nozzle configuration for your job.
To check the nozzles on the tractor spray bar, raise
the hog head, set the parking brake, activate the
high pressure system and set the operating pres-
sure to a safe level. Make sure the head rotation
speed dial is set to 0 so the spray bar does not
rotate. Staying well clear of the water jets, visu-
ally 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 is good.
