OPERATION
EXPLANATION OF COMPONENTS
ENGINE WATER TEMPEARTURE GAUGE
This gauge (2) indicates the cooling water temperature.
When the indicator is in the white range during operation, the
water temperature is normal.
If the indicator moves from the white range into the red range
during operation, stop the machine immediately, run the engine
under no load at a midrange speed, and wait for the indicator to
go down to the white range. After starting the engine, warm up
it until the indicator moves into the white range.
TRANSMISSION OIL TEMPERATURE GAUGE
This meter (3) indicates the temperature of the transmission
lubricating oil.
When the indicator is in the white range during operation, the
oil temperature is normal.
If the indicator moves from the white range into the red range
during operation, stop the machine, run the engine under no
load at a midrange speed, and wait for the indicator to go down
to the white range.
FUEL GAUGE
When the starting switch is turned ON, this meter (4) displays
the amount of fuel remaining in the fuel tank.
F indicates a full tank.
When the indicator points to E, it indicates that there is less
than 43 liters (11.35US gal) remaining, so add fuel.
Always fill the tank after finishing operations.

This lamp (5) warns of a rise in the temperature of the engine
cooling water.
If the lamp lights up, stop the machine, run the engine under no
load at a midrange speed, and wait for the indicator of the
