Hog Technologies is excited to welcome you and your crew to the Stripe Hog Operators’ Team. Together we embrace the challenge of constantly developing our equipment, knowledge and skills so that our highways will be safer for all who rely on them and our pavement surfaces will last longer for those who pay for them.
Hog Technologies warrants its components to be free from defects in material and workmanship while under normal use and service. Hog Technologies will, at its option, either repair or replace free of charge any such part that appears to us to be defective in material or workmanship during the warranty period.
IMPROPERLY. IMPORTANT NOTE: Every precaution has been taken by Hog Technologies to reduce the risks associated with possible injury and damage from electrical faults, high pressure water and hydraulic components or mechanical failure. However, your own precaution and good maintenance procedures are necessary in order to maintain a safe working environment.

Section 2 - Stripe Hog Systems Rupture Discs There are two rupture discs installed on the high pressure side of the UHP pump that protect the high pressure water blasting system against un- usually high spikes in pressure. The rupture discs are designed to burst and immediately relieve pressure if the water pressure in the ultra-high pressure system exceeds the disc burst rating.

Section 2 - Stripe Hog Systems Wear Brush The wear brush clamped to the bottom of the shroud provides a partial seal between the shroud and pavement. The wear brush regulates vacuum air flow into the shroud and reduces the amount of debris and water exiting the blasting head dur- ing water blasting operations.
Section 2 - Stripe Hog Systems 2.8 High Pressure Hoses, Connections & Fittings The ultra-high pressure hoses used in the water blasting system are tough but not invincible. They require proper care and handling to achieve maximum life expectancy. Only use high pressure hoses with an operating pressure rating of 40,000 psi (2758 Bar) and a listed burst rating of 60,000 psi (4,137 Bar).

Section 2 - Stripe Hog Systems Filter And Filter Canister The vacuum filter canister houses the vacuum filter which protects the blower from debris. The filter should be checked at the beginning of each shift and periodically during operation. It is normal for some water vapor to travel from the debris tank to the vacuum filter canister where it will accumulate.

Section 2 - Stripe Hog Systems Typical Debris Tank Tilted for Dumping Debris Tank Dump System Solid debris is separated from the wastewater by the 100 micron filter bag and needs to be dumped when the debris cage is near full. A hydraulic ram below the tank lifts the passenger side, causing the tank to tilt for easy dumping.
Section 2 - Stripe Hog Systems 2.10 Optional Hog Tool Auxiliary Connection General When this option is installed, an optional Ground Hog or other Hog Tool is connected to the aux- iliary connections. The electrical system senses that the tool is connected and the levers on the tool then control Ultra-High Pressure water to the blast head and hydraulic fluid flow to the spray bar motor.
Fuses in the outside terminal box (OTB) protect accessory circuits acti- vated by switches in the panel and other electrical equipment installed by Hog Technologies. Main Circuit Breakers The 50 and 30 amp main breakers are connected directly to the skid batteries and supply electri- cal power to the OTB accessory fuse panels.
