EXPLANATION OF COMPONENTS
OPERATION
3-18
ENGINE COOLING WATER TEMPERATURE CAUTION LAMP
This lamp (4) lights up to warn the operator that the engine
cooling water temperature has risen.
During checks before starting (when the starting switch is
turned to the ON position but the engine is not started), this
monitor does not light up.
During operation (engine running)
If the engine cooling water temperature rises, the engine cool-
ing water temperature caution lamp only will light up.
If the water temperature rises further, the central warning lamp
will light up and the alarm buzzer will sound intermittently.
At the same time that the central warning lamp lights up, “E02“
and “ENGINE OVERHEAT“ are displayed on the character dis-
play in turn, so stop the machine and run the engine at a mid-
range speed under no load until the lamp goes out.
FUEL LEVEL CAUTION LAMP
This lamp (5) lights up if the amount of fuel remaining in the
fuel tank goes below 31 liters (8.19 US gal).
If it lights up, check and add fuel as soon as possible.
REMARK
Even if the caution lamp lights up, action code “E02“ is not dis-
played on the character display.
WARNING/LIMIT FUNCTIONS FOR TRAVEL SPEED 3
When the travel speed goes above 40.0 km/h (24.9 MPH), the
central warning lamp lights up and the alarm buzzer sounds.
At the same time, “E00“ is displayed on the character display,
and then “OVERRUN PROTECT“ and “E00“ are displayed in
turn for 3 seconds each.
If the alarm buzzer sounds, ease the accelerator pedal back
and reduce speed.
TRAVEL SPEED LIMIT FUNCTION
The travel speed is automatically controlled so that it does not go above approx. 42 km/h (26.1 MPH).
