3.3 Basic check items
9. Hydraulic oil temperature gauge
This meter (9) displays the hydraulic oil temperature.
During operations, the indicator should be in the black range.
If the indicator enters red range (A) during operations, the
hydraulic oil temperature has gone above 102°C. Stop the
engine or run it at low idle and wait for the hydraulic oil tempera-
ture to go down.
REMARK
When the indicator is in the red range (A) to (B), the hydraulic oil
temperature is as follows.
Red range position (A): More than 102°C.
Red range position (B): More than 105°C.
When the indicator is in the red range (A) to (B), hydraulic oil
temperature monitor (1) lights up red. When indicator is between
A and C the hydraulic oil temperature monitor (1) remains green.
If the indicator is at position (C) when the engine is started, the
hydraulic oil temperature is less than 25°C, and hydraulic oil
temperature monitor (1) lights up white. In this case, carry out
the warming-up operation.
For details, see "Warming up operation (3-115)".
REMARK
If other warnings are displayed, only monitor (1) is displayed and
not the range indicator.
10. Service meter and clock
This monitor (10) displays the total time that the machine has
been operated. When the engine is running this display changes
to a clock.
Use the time display to set the maintenance interval. When the
starting switch is ON, the service meter advances even if the
machine is not moving.
The service meter advances by 1 for every hour of operation,
regardless of the engine speed.
