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 at 1-866-443-2576 –
Powerhorse. 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.
