IMPORTANT: If charging system or oil pressure indicators (C or B) fail to go out, or temperature gauge (A) indicates hot, stop engine and determine the cause.

Coolant Temperature Gauge (A)

The needle on the temperature gauge rises as engine warms up. If needle reaches red zone, stop engine and determine the cause.

Check coolant level in recovery tank and radiator when engine cools. Also check grille, radiator and radiator screen for plugging. Check fan belt tension. If problem is not corrected, see your John Deere dealer.

Oil Pressure Indicator (B)

Oil pressure indicator will light if engine oil pressure is low. Indicator should light when key is turned to RUN position and go out when engine starts.

IMPORTANT: NEVER operate engine without sufficient oil pressure. If indicator stays lit for longer than five seconds under normal operating conditions, stop engine and check for cause.

If low oil level is not the problem, see your John Deere dealer.

Charging System Indicator (C)

Charging system indicator will light when alternator output is low.

If indicator stays lit for longer than five seconds in normal operation, stop engine and check for cause. If loose or broken fan belt is not the cause, see your John Deere dealer.

Air Restriction Indicator (D)

Air restriction indicator will light if air cleaner becomes plugged. Service air cleaner as soon as possible.

Fuel Level Gauge (E)

Stop to refuel before fuel gauge reaches empty mark.

IMPORTANT: Use diesel fuel only. See Fuel, Lubricants and Coolant section for fuel specifications.

Should tractor run out of fuel and not start in several tries, air must be bled from fuel system. (See Bleed Fuel System in Maintenance—Fuel System section.)

Park Brake (F)

At ignition mode of key switch, park brake indicator light illuminates on display when transmission is in park pawl condition.

QRL Indicator (G)

QRL Indicator illuminates when hitch malfunction occurs. If necessary, have the John Deere dealer diagnose vehicle.
