UsIng Indicator Lights

TCAL43729-UN-21MAR13

• Hourmeter (A) will display number of hours machine has run.
• Engine Coolant Temperature Indicator (B) will glow if engine temperature becomes excessive. Stop engine and determine cause.

NOTE: Deck lift and PTO functions will be disabled whenever the Engine Coolant Temperature indicator is illuminated.

• Battery Discharge Indicator (C) will glow when alternator is not producing adequate voltage. Stop engine and determine cause.
• Hydraulic Oil Temperature Indicator (D) will glow when hydraulic oil temperature is high and deck lift and PTO functions will stop. Let hydraulic oil temperature cool by allowing engine to idle under a no-load situation. This keeps the oil flowing through the oil cooler and cools the oil. Check oil level and make sure oil cooler coils are clean. Continued operation may cause higher temperatures, resulting in damage.

NOTE: Deck lift and PTO functions will be disabled whenever the Hydraulic Oil Temperature indicator is illuminated.

• Engine Glow Plug Indicator Light (E) will glow when key switch is turned to the run position. After approximately 3 to 15 seconds the light will go out.
• Diagnostic Indicator Light (F) will flash a diagnostic code to help the operator identify operational and electrical problems. (See Diagnostics in this section.)
• Engine Oil Pressure Indicator (G) will glow when engine oil pressure is low. If lamp glows when engine is running, stop engine immediately. (See your John Deere distributor.)
