Do Not Modify Fuel System

IMPORTANT: Increasing horsepower or altering fuel and air delivery beyond the factory rating causes emissions to exceed United States Environmental Protection Agency (EPA) approved levels. Violations of EPA regulations can result in substantial fines to persons or companies committing such violations.

Machine warranty is void if power level is changed from factory specifications.

Do not attempt to service injection pump or fuel injectors yourself. Special training and special tools are required. See your John Deere dealer.
