Confirmation of the oil Temperature
Confirm the oil temperature is between 45° - 55° C using the
self check function. If the temperature is low use the following
warm-up procedure.
Warming-up Procedure
1
Turn the Throttle Control to mid-range and make sure the
Work Mode Selection Switch is set to S.
2
Press the One Touch Idle Switch.
3
Run the engine until the Coolant Temperature gauge
reads within the normal (green) range.
4
Set the Servo Isolator Switch to ON to enable the
hydraulic servo controls to be operated.
5
Operate the bucket control slowly until it reaches one end
of its travel and leave it there for 30 seconds.
6
Operate the bucket control slowly to the other end of its
travel and leave it there for 30 seconds.
7
Repeat steps 5 and 6 for 10 minutes to warm up the
hydraulic circuit.
8
Now operate the excavating controls three to five times in
each direction to distribute warm hydraulic oil around the
system.
