3.2 Hog Tool Waterblast Systems

General

When a Hog Tool is connected to the auxiliary

connections, the Waterblasting electrical system

senses that a tool is connected and allows the

levers on the tool to control the dump valve and

hydraulic pressure to the blast head thru-shaft

motor. The truck hydraulic system provides the

hydraulic power that rotates the spray bar on the

Hog Tool. The truck UHP pump and vacuum sys-

tem provides water pressure and vacuum.

Hydraulic and electrical Systems

Hydraulic hoses with quick disconnect fittings are

connected the to the truck hydraulic system. The

hydraulic manifold on the truck controls the oil

flow and regulates the pressure. Switches and/or

control knobs on the Hog Tool provide the operator

with control of the hydraulically activated features.

A 12-Volt DC harness runs from the outlet plug

on the front of the truck to a plug on the tool and

allows the switch lever on the tool to activate the

spray head rotation.

High Pressure Waterblasting System

The High Pressure water line runs from the UHP

pump and dump valve on the SH5500 to the Hog

Tool. The manual bypass valve on the UHP pump

and engine RPM is used to adjust the volume and

pressure supplied to the tool.

When the SH5500 is connected to a Hog Tool, the

high pressure water is controlled by a lever on the

tool handle. The control lever activates a switch

that sends electrical current to the dump valve on

the UHP pump to engage or disengage high water

pressure water at the blasting head on the tool.

When the system is activated, it operates much

like the truck mounted high pressure water sys-

tem. The tools must be moving before the high

pressure is activated and all waterblasting safety

precautions apply.

High pressure hoses and fittings can be dangerous

if a hose bursts or a fitting fails during high pres

sure blasting. Outfit the Hog Tool operator with

proper safety apparel. Hard hat, safety shield or

glasses, gloves, ear protection, etc.

DANGER

THE SINGLE BLASTING HEAD ON THE TRACTOR OR ANY
OTHER HOG TOOL WILL BE OVERPOWERED BY THE SH5500
HIGH PRESSURE PUMP IF THE SYSTEM IS NOT ADJUSTED
TO THE REDUCED VOLUME FOR A SINGLE BLASTING HEAD.
FAILURE TO ADJUST THE SYSTEM WILL PROVIDE TOO
MUCH PRESSURE TO THE SPRAY HEAD THAT WILL CAUSE
THE RUPTURE DISCS TO BLOW AND COULD CAUSE SEVERE
DAMAGE TO THE UHP SYSTEM AND/OR INJURY TO THE
OPERATOR OR CREW WHEN THE SYSTEM IS ACTIVATED.

WHEN SWITCHING THE UNIT FROM THE MAIN HOG HEAD TO
EQUIPMENT WITH A SMALLER BLASTING HEAD, ALWAYS
ENGAGE THE TRUCK OMSI DRIVE PTO WITH THE ENGINE
AT IDLE AND TURN THE DUMP VALVE ON. GRADUALLY
INCREASE THE RPM WHILE ADJUSTING THE MANUAL
BYPASS VALVE UNTIL THE DESIRED PRESSURE AND
VACUUM FOR THE BLASTING HEAD IS ACHIEVED. THIS
PROCEDURE MUST BE DONE BEFORE THE TRACTOR OR
HOG TOOL IS USED AND MUST NEVER BE OVERLOOKED.

3.3 Hog Tool Vacuum Systems

The HT1100 Hog Waller and HT1000 Ground Hog

are equipped with blast heads that are designed

to be attached directly to the SH5500 vacuum

system. When the system is activated, it per-

forms much like the vacuum system when it is

connected to the truck blast head. Vacuum is

supplied whenever the engine on the SH5500 is

running and the OMSI Drive PTO is engaged.
