Do Not Modify Fuel System

TS1343-UN-18MAR92

CAUTION: Do not open high-pressure lines.

High-pressure fluid remaining in fuel lines can cause serious injury. Do not disconnect or attempt repair of fuel lines, sensors, or any other components between the high-pressure fuel pump and nozzles on engines with High Pressure Common Rail (HPCR) fuel system.

Only technicians familiar with this type of system can perform repairs. (See your John Deere Dealer.)

IMPORTANT: Never steam clean or pour cold water on a warm high pressure pump. To do so may cause seizure of pump parts.

Modification or alteration of the high pressure fuel pump (A), injection timing, or fuel injectors not recommended by the manufacturer will terminate the warranty obligation to the purchaser.

In addition, tampering with fuel system which alters emission-related equipment on engines may result in fines or other penalties, per EPA regulations or other local emission laws.

Do not attempt to service high pressure pump or fuel injectors yourself. Special training and tools are required. (See your authorized servicing dealer or engine distributor.)
