High Altitude
Operation CAUTION : Operating at an altitude of greater than 5000 feet (1500 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.
