3.6. Individual Operations of Maintenance
For easier cleaning it is possible to dismantle the whole upper
cover 1 with the ller. If you dismantled the whole upper cover,
use a new teon sealing strip.
Drain oil after it has cooled down below
50 °C (122 °F).
Follow the re safety measures!
After disconnecting the hydraulic cir-
cuits blind all holes with plugs.
Collect drained oil; do not leave it soak
into the soil.
Used oil is environmentally dangerous
waste - have them liquidated.
Checking the oil thermometer sensor
Dismantle the sensor and clean the contact.•
Dip the sensor into warm oil of known temperature and •
read out the oil temperature on the thermometer. Replace
the sensor if not working properly.
Filling the hydraulic circuit:
Use a lling device with the following parameters:•
min. pressure 6 MPa (870 PSI)
ltering property 3 to 10 µm
Open the cover on the right side under the cabin and re-•
move the cap of lling terminal.
Mount the quick coupling of the lling device to the quick •
coupling. Fill the hydraulic circuit until clean oil starts to ow
out of the hose. Collect it to a clean vessel.
