Prepare Machine for Maintenance

IMPORTANT: Improperly disposing of waste can threaten the environment and ecology. Potentially harmful waste used with John Deere equipment includes such items as oil, fuel, coolant, brake fluid, filters, and batteries. Do not pour waste onto the ground, down a drain, or into any water source.

Before performing procedures in the maintenance chapters and before leaving the operator's seat, park the machine and position hydraulic functions as described in Parking the Machine in Driving the Machine chapter, unless another position is specified.

CAUTION: Prevent serious injury or death from unexpected machine movement. Always install the loader boom service lock, or lower the front loader boom fully to the ground, and move control levers to release hydraulic pressure before working near the front of the machine. (See Loader Boom Service Lock in this chapter for installation instructions.)

IMPORTANT: Do not raise or lower the front loader boom while the engine hood is open. Always close the engine hood fully before moving the front loader boom, or severe damage to the engine hood will occur. (See Opening and Closing the Engine Hood in this chapter for instructions.)

Raise the front loader boom and install the loader boom service lock before performing maintenance in the engine compartment. (See Loader Boom Service Lock in this chapter for installation instructions.)

If the machine is equipped with ride control, discharge hydraulic pressure from the ride control system before performing maintenance. (See Discharge Ride Control System Hydraulic Pressure-If Equipped in Maintenance chapter.)
