Section 5:
Scheduled Maintenance
5.1 Scheduled Maintenance Introduction
Most components of the water blasting system
require specific maintenance at scheduled intervals
recommended by the component manufacturer or
Hog Technologies. Maintenance schedules and ser-
vice procedures for the primary components of the
water blasting 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
identifies the recommended service and/or lubrica -
tion intervals for each primary component of the
water blasting system. You should become familiar
with the maintenance and lubrication requirements
of all components. Some of the lubrication points
on components such as the blower, UHP pump
and thru-shaft motor bearings require specialized
lubricants. The use of any lubricant other than the
lubricant specified 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.

5.2 Truck Maintenance
Engine and Chassis
Proper engine and chassis maintenance is essen-
tial to the proper performance and reliability of
the Stripe Hog truck. You should perform all rec-
ommended maintenance according to the manu-
facturers’ specifications. Maintenance schedules
and procedures are outlined in the truck owner’s
manual. They should be followed exactly.
Drive PTO
A transfer case/PTO is used to disconnect the truck
drivetrain and engage the hydrostatic drive sys-
tem. Maintaining the fluid levels and performing
routine maintenance is important in the transfer
case. Maintenance schedules are outlined in the
manufacturer’s operating manual included with
your truck. They should be followed exactly.
Refer to the Lubrication Chart and Maintenance
Matrix in this section for lubrication specifications.
Weekly/50 Hour Maintenance:
• Check fluid level in the transfer case and in -
spect for signs of leakage. The fluid level is
checked by removing the plug on the side of
the case. The fluid level should be maintained
within .5” (1.3 cm) of the plug threads.
• Inspect components for loose bolts and uni-
versal joints.
Periodic Maintenance:
• Grease drive shaft splines and universal joints
monthly/200 hours.
• Change fluid in the transfer case as recom -
mend in the manufacturer’s manual.
