justed whenever the spray bar is removed. The
dirt shield should be replaced if it is damaged or
worn and be adjusted “finger tight.” If it is too
tight it will prevent the spray bar from rotating.
With the spray bar installed, operate the pump
at low pressure to check for nozzle accuracy and
leaks on the spray bar or nozzles. Water dripping
from any of the weep holes in the side of the spray
bar indicates that a nozzle is not seated properly.
Leaks at the nozzle seats or thru-shaft threads
must be corrected before beginning high pres-
sure operations or the spray bar will be ruined.
Should any repairs or adjustments be necessary,
disengage the pump to relieve all pressure before
making any required repairs or adjustments.
Each spray bar is equipped with a spray bar pro-
tector that is held in place with one or two cotter
pins, depending on the size of the spray bar. The
spray bar protector shields the nozzles and spray
bar from damage caused by debris during blasting
operations. Never water blast without the spray
bar protector installed. Spray bars and nozzles
are expensive and the life of the nozzles and spray
bars will be dramatically shortened without the
spray bar protector.

Notice:
Never Blast When Stopped. Damage to road
surface will occur if blasting continues when
the Stripe Hog is brought to a stop.
3.3 Tractor Waterblasting
The tractor Hog Arm and Hog Head are supplied
high pressure water and vacuum from the SK3000
waterblasting system. Quick disconnect fittings on
the hoses and swing arm booms allow the tractor
to be quickly connected to the SK3000 systems
and enable unrestricted movement of the trac-
tor around the truck. The operation of the Ultra
High pressure water is controlled by the operator
on the tractor. Refer to the Water Blast System
(Section 2.6) of this manual for information on
waterblasting controls and systems.
High pressure hoses and fittings can be dan -
gerous if a hose fails or a fitting breaks dur -
ing high pressure blasting. Outfit the tractor
operator with proper safety apparel. Additionally,
the operator must always be aware of the maxi-
mum distance from the truck the hose length will
allow. The SK3000 is capable of supporting the
