A - Engine Oil Dipstick

IMPORTANT: Do Not operate engine when oil level is below “ADD” mark on dipstick.

NOTE: A tag is located on the dipstick tube to alert the operator of the break-in oil. After break-in has been completed, discard tag.

The engine in this machine was filled at the factory with John Deere Break-In Plus™ Engine Oil and is ready for normal operation. However, extra care during the first 375 hours of operation will result in more satisfactory long-term engine performance and life.

During the first 20 hours of operation, operate the engine under various conditions, particularly heavy loads with minimal idling, to help seat engine components properly. Avoid prolonged periods of engine idling or sustained maximum load operation. If engine is going to idle longer than 5 minutes, stop engine.

IMPORTANT: DO NOT add makeup oil unless oil level is BELOW the ADD mark on dipstick. John Deere Break-In Plus™ must be used to make up any oil consumed during the break-in period. (See JOHN DEERE BREAK-IN PLUS ENGINE OIL in Fuels, Lubricants, and Coolants section.)

DO NOT use Plus-50™ or Plus-50™ II Engine Oil during break-in period. These oils will not allow engine to wear properly during this break-in period.

DO NOT fill above the FULL mark. Oil levels anywhere within the crosshatch marks are considered in the acceptable operating range.

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

Verify that dipstick is completely in housing before removing to check oil level.

Remove dipstick (A) and check oil level daily. Oil level must be between ADD mark and top of crosshatch area on dipstick. If oil level is below ADD mark, add oil as needed.

After the first 375 hours maximum, change engine oil and replace engine oil filter. Fill crankcase with John Deere Plus-50™ II or other diesel engine oil. (See DIESEL ENGINE OIL in Fuels, Lubricants, and Coolants section for proper oil.)

A - Engine Coolant Temperature Gauge

B - Coolant Surge Tank

Watch engine coolant temperature gauge (A) closely. If needle on gauge rises into warning zone and caution indicator light comes on, engine is overheating. Shift to lower gear or reduce load by reducing ground speed. Unless temperature drops quickly, STOP engine. Determine cause of overheating.

CAUTION: The explosive release of fluids from pressurized cooling system can cause burns resulting in serious injury or death to you or others. Do not remove surge tank cap until it is cool enough to touch with bare hands. Shut off engine and wait until it cools. Then slowly loosen cap to relieve pressure before removing it completely.

Check coolant level in surge tank (B) frequently during break-in period, when engine is cold. Watch for any signs of leaks. Coolant level must remain between maximum and minimum cold level marked on tank.
