• Use the correct container to get an oil sample and make sure that it is
clean. An incorrect or dirty container causes contamination of the oil. For
information on the equipment that you can use to get an oil sample, refer
to section
• Measure the quantity of oil that you drain from the device. This includes
the quantity of the oil sample. Add the same quantity of new oil to the gear
unit or the hydraulic system after you complete this task. Use the same oil
as the oil in the gear unit or the hydraulic system.
Procedure
1. Hold a container below the opening of
the sample point (A).
2. Turn the handle (B) counterclockwise
to open the sample point.
Make sure that the stop is removed
from the sample point.
3. Fill the container with oil.
Make sure that the flow of oil from the
sample point is constant.
4. When the container contains sufficient
oil, turn the handle clockwise to close
the sample point.
5. Remove the container.
Drain the oil from the device
Procedure
1. Stop the device. Refer to section
2. Close the drain valve on the connecting gear unit, hydraulic system, or container.
3. Disconnect the suction hose from the drain valve of the gear unit, hydraulic system,
or container.
4. Hold the suction hose up to make sure that no oil can flow out of the suction hose.
5. Start the device. Refer to section
on page 25.
This removes the oil from the suction hose and the suction area of the device.
Caution: The oil level in the gear unit or the hydraulic system must not
become too high.
6. Stop the device. Refer to section
on page 25.
7. Disconnect the return hose from the gear unit, hydraulic system, or container.
8. Seal the hoses with a plug and lay them on the ground.
