Dirt Shield
The dirt shield is a threaded stainless steel flat washer that protects the thru-shaft seals and bearings
from dirt and debris during ultra-high pressure blasting operations. It is located between the spray
bar and the shroud and consists of a special felt gasket that protects the shroud from damage while
the spray bar is rotating. The dirt shield should be inspected prior to the start of each shift as part of
the pre-start procedure and replaced if it becomes worn or damaged. When installing a dirt shield, it
should be adjusted “finger tight.” If it is set too tight it will prevent the spray bar from rotating. (Refer
to the Dirt Shield Installation procedure in the Maintenance section of this manual for instructions for
replacing the dirt shield).
