HIGH ALTITUDE OPERATION NOTICE This pressure washer is NOT equipped with an altitude carburetor modification. Even with a carburetor modification, engine horsepower will decrease about 3.5% for each 300 meter (1,000 foot) increase in altitude. The effect of altitude on horsepower will be greater if no carburetor modification is made. A decrease in engine horsepower will decrease the power output of the pressure washer. Contact our service team to order altitude kits.
