HIGH ALTITUDE OPERATION
CAUTION: Operating at an altitude of greater than 2000 feet (610 meters) may affect your engines
performance, fuel consumption, and emissions. To remain emissions compliant and improve engine
performance at higher altitudes, a high-altitude kit is required. A high altitude kit includes a carburetor
jet resized to help correct air / fuel mixture at altitude. To order a high altitude kit or if you have
additional questions, go to www.northerntool.com or contact us at1-877-234-6869. Please note,
engines with the high-altitude kit installed operated at lower altitudes could cause severe engine
damage and affect emissions compliance. When modified, a tag or decal should be added to the
product stating that a high-altitude kit was installed and to remind you to re-service the carburetor (re-
jet) when operating in lower altitude environments.
Note: Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-
foot (300-meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
