Starting the Engine

TS220-UN-15APR13

Use Proper Ventilation

The following instructions apply to the optional controls and instruments available through the John Deere Parts Distribution Network. The controls and instruments for your engine may be different from those shown here; always follow manufacturer's instructions.

CAUTION: Before starting engine in a confined building, install proper outlet exhaust ventilation equipment. Always use safety approved fuel storage and piping.

NOTE: If temperature is below 0°C (32°F), it may be necessary to use cold weather starting aids (See COLD WEATHER OPERATION, later in this section).

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

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

3. Disengage power (or clutch if equipped) to any engine drivelines.

   Analog Throttle Control and Speed Select Switch

   A - Analog Throttle Control (Optional)

   B - Speed Select Rocker Switch

   Set slow idle as follows:

   Panels with high-low speed select rocker switch (B) only: Set slow speed by pressing lower half of switch.

   Panels with optional analog throttle(s) (A) : Set high-low speed select rocker switch to slow (turtle), then push in on analog throttle handle or turn full counterclockwise to set analog throttle(s) to slow speed.

   IMPORTANT: Do not operate the starter for more than 30 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.

5. Turn the key start switch (A) clockwise to the “ON” position. Wait until the Engine Preheater Indicator light turns off, then turn the key start switch clockwise “START” position to crank the engine. (In cold weather, preheater indicator light remains on longer while engine is warmed. See COLD WEATHER OPERATION later in this section.) When the engine starts, release the key switch so that it returns to the “ON” position.

   Start And Idle Engine Controls On Instrument Panel

   A - Key Start Switch

   B - High-Low Speed Select Rocker Switch

   C - Bump Speed Enable Rocker Switch

   D - Speed Select Rocker Switch

   E - Analog Throttle Control (Optional)

   IMPORTANT: If the key switch is released before the engine starts, wait until the starter and the engine stop turning before trying again. This will prevent possible damage to the starter and/or flywheel.

6. After engine starts, idle engine at not more than 1200 rpm until warm. (See WARMING ENGINE later in this section).

   Panels with high-low speed select rocker switch (B) only: Set rpm using bump speed enable switch (C) with speed select rocker switch (D).

   Panels with optional analog throttle (E): Set either high-low speed select switch (B) or analog throttle (E) to slow speed, and set desired speed with remaining control. (See “Changing Engine Speeds” later in this section).

   NOTE: Engine control unit (ECU) reads the higher of the high-low speed select rocker switch or the analog throttle speed settings.

7. Check all gauges for normal engine operation. If operation is not normal, stop the engine and determine the cause. (For normal gauge pressures and temperatures, see BREAK-IN SERVICE earlier in this section.)
