Cold Weather Starting

When outside temperatures fall below 0°C (32° F) it may be necessary to consider using cold weather starting aids.

Your PowerTech™ Engines may be fitted with a block heater, air intake heater and increased capacity battery and/or lower viscosity oil may also be used. See your local John Deere engine distributor or servicing dealer for recommendations. (Also see “Using a Booster Battery or Charger” later in this section.)

1. Perform all prestarting checks outlined in Lubrication & Maintenance/Daily Section later in this manual.

2. Disengage engine rear driveline (if equipped) or gen set drive.

3. Open the fuel supply shut-off valve, if equipped.

4. Place the speed control lever in the “START” position, if equipped.

5. IMPORTANT: Do not operate the starter for more than 15 seconds at a time. To do so may overheat the starter. If the engine does not start the first time, wait at least 2 minutes before trying again. If engine does not start after four attempts, see Troubleshooting Section.

   Turn key switch to “ON” position and hold “PREHEAT” button (if equipped with preheat option) in for up to 30 seconds. Turn key switch to “START” while continuing to hold the “PREHEAT” button and the reset button. Hold until engine starts. Release key and “PREHEAT” button once engine starts; key automatically returns to “ON” position and instrument panel gauges start operating. Release reset button when oil pressure is at a safe operating level.

6. Warm-up engine for at least 5 minutes before applying a load. (See WARMING ENGINE, later in this section.)
