ENGINE TACHOMETER
The engine tachometer indicates the engine speed.
If the engine speed is higher than the allowable range during
operation, the engine overrun caution lamp lights up in red.
At the same time, the centralized warning lamp lights up and
alarm buzzer sounds intermittently.
Operate the machine with moderate engine speed and travel
speed.
ENGINE COOLANT TEMPERATURE GAUGE
Engine coolant temperature gauge shows the engine coolant
temperature.
When the indicator is in white range (A) or green range (B) dur-
ing operation, it is normal.
If the indicator is in red range (C), the engine coolant tempera-
ture caution lamp lights up in red, and action level “L02” is dis-
played.
At the same time, the centralized warning lamp lights up and
alarm buzzer sounds intermittently.
The engine output is then limited automatically.
Place the machine in a safe place, set the gear shift lever to NEUTRAL position (N), and run the engine at a
medium speed with no load until the engine coolant temperature caution lamp goes out.
TORQUE CONVERTER OIL TEMPERATURE GAUGE
The torque converter oil temperature gauge indicates the tor-
que converter oil temperature.
When the indicator is in green range (B) during operation, it is
normal.
If the indicator is in red range (C), the torque converter oil tem-
perature caution lamp lights up in red, and action level “L02” is
displayed.
At the same time, the centralized warning lamp lights up and
alarm buzzer sounds intermittently.
Place the machine in a safe place, set the gear shift lever to
NEUTRAL position (N), and run the engine at a medium speed with no load until the torque converter oil tem-
perature caution lamp goes out.
RETARDER OIL TEMPERATURE GAUGE
The retarder oil temperature gauge indicates the retarder oil
temperature.
When the indicator is in green range (B) during operation, it is
normal.
If the indicator is in red range (C), the retarder oil temperature
caution lamp lights up in red, and action level “L02” is dis-
played.
Place the machine in a safe place, set the gear shift lever to
NEUTRAL position (N), and run the engine at a medium speed
with no load until retarder oil temperature caution lamp goes
out.
