Do Not Modify Fuel System

IMPORTANT: Modification or alteration of the injection pump, injection pump timing or fuel injection nozzles in ways not recommended by the manufacturer will terminate the warranty obligation of the engine manufacturer. See warranty information on inside front cover.

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

John Deere dealers are in violation of their dealership agreement if found to be altering power levels of John Deere equipment.

Forage harvester warranty is void if power level is changed from factory specifications.

Never steam clean or spray water on a warm injection pump. This could cause damage to pump parts.
