Section 5:
Scheduled Maintenance
5.1 Scheduled Maintenance Introduction
Most components of the waterblasting system re-
quire specic maintenance at scheduled intervals
recommended by the component manufacturer
or Hog Technologies. Maintenance schedules and
service procedures for the primary components
of the waterblasting system are covered in this
section.
The information on components manufactured and
supplied by other manufacturers outlined in this
section is a general overview of the maintenance
recommended and steps required. Always refer to
the component manufacturer’s manuals for more
detailed information and additional maintenance
information.
The Maintenance Matrix at the end this section
identies the recommended service and/or lu-
brication intervals for each primary component
of the SH8000 Waterblasting system. You should
become familiar with the maintenance and lubri-
cation requirements of all components. Some of
the lubrication points on components such as the
blower, ultra high pressure pumps and thru-shaft
motor bearings require specialized lubricants. The
use of any lubricant other than the lubricant speci-
ed will void the warranty on those components.
The maintenance intervals outlined in this section
are considered typical for units used in normal
operating conditions. Units used in extremely dirty
conditions, high temperatures or other severe duty
applications will require more frequent service.
THE SCHEDULED MAINTENANCE PROCEDURES IN
THIS SECTION MUST BE FOLLOWED EXACTLY TO
AVOID DAMAGING COMPONENTS AND/OR VOIDING THE
WARRANTY.
5.2 Periodic Maintenance Items
The primary components in the waterblasting sys-
tem have specic stated service intervals. Other
components that support primary equipment re-
quire periodic inspection and routine maintenance.
Many of those items are mentioned in this section.
