A - Coolant Temperature Gauge

B - Engine Information Indicator

C - Charging Indicator

IMPORTANT: The engine is ready for normal operation. However, extra care during the initial break-in period will result in more satisfactory long-term engine performance and life.During the initial operation of a new engine, change the oil and filter between a minimum of 100 hours and a maximum equal to the specified John Deere Plus 50 or John Deere Plus 50 II engine oil.

1. Warm up engine at slow rpm. Check coolant temperature gauge (A), engine information (B) and charging (C) warning indicators.
2. Operate the engine at heavy loads with minimal idling during the break-in period.

   During the first 20 hours, avoid prolonged periods of engine idling or sustained maximum load operation. If engine will idle longer that 5 minutes, stop the engine.

3. Check engine oil, coolant, transmission/hydraulic, and mechanical front wheel drive (if equipped) fluid levels frequently. Watch for fluid leaks.

NOTE: Some increase in oil consumption may be expected when low viscosity oils are used. Check oil levels more frequently.

If air temperature is below -10° C (14° F), use an engine block heater.

IMPORTANT: This engine is factory-filled with John Deere ENGINE BREAK-IN OIL.

If the engine has significant operating time at idle, constant speeds, and/or light load usage, or makeup oil is required in the first 100 hour period, a longer break-in period may be required. In these situations, an additional 100 hour break-in period is recommended, using a new change of John Deere Engine BREAK-IN OIL and a new John Deere oil filter.

Check engine oil level more frequently during engine break-in period.

Do not add make-up oil until the oil level is BELOW the ADD mark on dipstick. If make-up oil is required during the break-in period, John Deere Engine Break-In Plus oil should be used whenever possible.
