OPERATION
EXPLANATION OF COMPONENTS
ENGINE COOLING WATER TEMPERATORE GAUGE
This gauge (1) indicates the temperature of the cooling water.
If the temperature is normal during operation, the green range (B)
will light.
If the red range (C) lights up during operation, move the Fuel
control dial to lower the engine speed to approx. 3/4 of the full
speed, and run until the water temperature enters the green range
(B).
If the engine cooling water temperature enters the red range, and
the engine water temperature monitor flashes and the alarm
buzzer sounds, stop the machine and run at low idling until the
water temperature enters the green range.
(A): White range
(B): Green range
(C): Red range
NOTICE
If
the
water
temperature
gauge
often
enters
the
red
range
(C),
check
the
radiator
for
clogging.
POWER TRAIN OIL TEMPERATORE GAUGE
This gauge(2) indicates the oil temperature of the torque converter
outlet. If the temperature is normal during operation, the green
range will light.
If the red range (C) lights up during operation, move the fuel control
lever to lower the engine speed to approx. 3/4 of the full speed,
reduce the load and run until the oil temperature enters the green
range (B).
If the power train oil temperature enters the red range, and the
power train oil temperature caution lamp flashes and the alarm
buzzer sounds, stop the machine and run at low idling until the oil
temperature enters the green range.
(A): White range
(B): Green range
(C): Red range
NOTICE
If
the
power
train
oil
temperature
gauge
often
enters
the
red
range
(C),
we
recommend
you
to
lower
the
travel
speed
one
range
(for
example,
F2
→
F1)
to
reduce
the
load
on
the
