Stripe Hog Systems
Tool Boxes
Heavy duty, lockable tool boxes are located on
the truck chassis. The tool boxes are used for the
storage of hoses, fittings, extra parts and tools.
Instructions for routine maintenance and adjust-
ing the latches are located on labels attached to
the inside of the each door.
2.2 Truck Power System and PTO
All major components of the Stripe Hog are
powered by the truck engine. The primary drive
system has two modes, Drive Mode and Work
Mode. Drive Mode connects the drive shafts from
the transmission directly to the differential and
is the normal mode for highway driving. Work
Mode disconnects the transmission from the dif-
ferential and connects it to the transmission Power
Take-OFF (PTO), the OMSI Drive and the hydraulic
systems that power the hydrostatic truck drive
and all waterblasting features and components.
Controls in the cab allow the operator to switch
quickly between Drive Mode and Work Mode. A
specially designed gear box called the “OMSI
Drive” and the Power Take-Off (PTO) on the truck
transmission facilitate this operation. The OMSI
Drive transfers the energy in the drive shaft from
the differential to special belts and pulleys that
power the high pressure water pump and vacuum
blower. It also provides power to the hydraulic
pump that powers the hydrostatic drive system.
The transmission PTO transfers drive train energy
to the hydraulic pump that powers the Hog Head
and waterblasting hydraulic systems. Pneumati-
cally activated control levers on the OMSI Drive
and truck transmission shift the unit from Drive
Mode to Work Mode when the PTO switches are
activated.
An electric air compressor, located on the passen-
ger side of the chassis, below the clean water tank,
provides the compressed air for the pneumatic
control actuators. The compressor is completely
automatic and always activated unless it is turned
OFF by the switch on the pressure control sensor
near the compressor.
The OMSI Drive gear box has specific lubrication
requirements. The fluid level must be checked
weekly to ensure the gear box is full and there are
no leaks. The fluid level is monitored by removing
the oil level plug on the OMSI Drive main gearbox.
The oil level should be maintained within .5” (1.3
cm) of the plug threads. Refer to the OMSI Drive
operating and maintenance manual for additional
Typical OMSI Drive
OMSI Drive Fluid Level Plug & Hydrostatic Drive
information on checking fluid the level and re
-
quired routine maintenance.
Shifting the Drive Modes
Changing from Drive Mode to Work Mode and back
again is orchestrated by using the clutch, gear
shift, and the PTO switches on the Waterblasting
joystick control panel and the truck dashboard.
The normal vehicle drive train is disabled and the
hydrostatic drive system moves the truck when-
ever the PTO switches are engaged.
The system should only be engaged into Work
Mode when the Stripe Hog is on a job site and
ready for operations. The truck must be stopped
with the engine at idle, the transmission in neutral
and the clutch depressed, before the transmission
and OMSI Drive PTO switches can be shifted from
Drive Mode (OFF) to Work Mode (ON.) In-cab
instructions are visible to assist in the start-up
and shut-down procedures for the operation of
the unit. The instructions are specific to each unit
