Section 4 - General Maintenance
4.8 Nozzle Installation
The condition of the nozzles is critical to removal
performance and maintaining a tight, cohesive
stream as water is forced through the nozzles.
Maximum productivity and 98% removal without
damage requires all nozzles to be in excellent
condition. Nozzles should be inspected before the
start of each shift as part of the pre-operation
check or when the operator notices a loss in pres-
sure or a change in performance while blasting. If
visual inspection of the nozzle spray pattern indi-
cates that the pattern is not in the # 1-4 quality
range as indicated on the Nozzle Quality Guide,
the nozzle must be replaced.
Use the following procedure when replacing
nozzles:
1. Make sure the Hog Arm and Head are in the
full up position and locked with the safety pin.
2. Make sure the water blasting system is shut-
down with the truck in the service position.
3. Remove the spray bar protector cotter pin and
the spray bar protector.
4. Remove worn or damaged nozzles.
5. Reactivate the truck and the water blasting
system by following the steps in the Start Up
Procedure.
6.
Turn the charge pump on and flush debris from
the spray bar with low charge pressure water.
7.
Once the spray bar is flushed, deactivate the
water blasting system and return the truck to
the service position.
8. Apply a light coat of anti-seize to the threads
on the new nozzles.
