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.

Stripe Hog Systems Dump Valve (Diverter Valve) The Dump Valve is a safety feature that is located on the Ultra-High Pressure pump manifold and controlled by the DUMP VALVE switch in the cap switch panel. When activated, it diverts (dumps) high pressure water from the blasting head to the clean water tank immediately eliminating the high pressure water at the blasting head.
