NOTE
● The hazard lights remain flashing even when the
starter key switch is in the OFF position.
● Allowing the turn signal/hazard lights to flash for
an extended period can lead to loss of battery
voltage.
NOTE
● In some cases, even when the parking brake lock
lever appears to be in the "LOCKED" position, the
parking brake itself may not be actually securely
locked.
IMPORTANT
● Decrease the load on the tractor:
• when the pointer on the coolant temperature
gauge reaches the abnormally high
temperature
• when the pointer on the coolant temperature
gauge jumps up or rapidly increases
● To lower the coolant temperature:
• idle the engine until the reading on the gauge
falls to the green zone
• shut off the engine
• allow the engine to cool down
● After the preceding actions, check the following:
• the coolant level in the radiator and in the
reserve tank are adequate
• the radiator and radiator screen are free from
dust deposits
• the alternator/fan belt tension is correct
For details, see “Chapter 14. PERIODIC SERVICE”
on page 14-1.
● If the pointer on the coolant temperature gauge
enters the red zone or the reading rapidly
increases again:
• shut down the engine
• immediately contact YOUR LOCAL YANMAR
