situation. The number of nozzles and the nozzle
orifice size will determine the aggressiveness of
the spray bar. As operators becomes more expe-
rienced, nozzle selection becomes easier. You can
also contact Hog Technologies Customer Support
toll free at (877) HOG-ROAD for assistance in
selecting the proper spray bar and nozzle con-
figuration for your job.
A nozzle should be removed from service if
any of the following are indicated:
• Nozzle is split or damaged
• Nozzle is clogged
• Nozzle water spray is fanned out
• Nozzle’s ability to hold pressure is suspect
• Nozzle’s hex head is worn excessively from
blasting
• Nozzle threads are damaged
When replacing nozzles make sure to check the
flow and pressure rating. Use only nozzles with a
manufacturer’s pressure rating of at least the UHP
pump’s maximum operating pressure. We recom-
mend that you only use nozzles, high pressure
hoses and fittings supplied by Hog Technologies
to ensure the nozzles and other components are
compatible with your Ultra-High Pressure water
blasting system.
Shroud
The shroud is the heavy duty stainless steel hous-
ing attached to the bottom of the Hog Head mo-
tor housing that encases the spray bar, keeping
water and debris contained for optimal vacuum
extraction. The vacuum hose is connected to the
top of the shroud by cam lock connectors. Shrouds
are available in various sizes to accommodate a
variety of spray bar lengths.
