Test or Replace the Hydraulic Oil
Replacement or testing of the hydraulic oil is
essential for good machine performance and
service life. Dirty oil and suction strainers may
cause the machine to perform poorly and
continued use may cause component damage.
Extremely dirty conditions may require oil changes
to be performed more often.
The machine uses Dexron II
equivalent hydraulic oil. Before
replacing the hydraulic oil, the oil
may be tested by an oil distributor
for specific levels of contamination
to verify that changing the oil is
necessary. If the hydraulic oil
is not replaced at the two year
inspection, test the oil
quarterly. Replace the oil when
it fails the test.
Perform this procedure with the
boom in the stowed position.
1 Place a suitable container under the hydraulic
power unit reservoir.
2 Remove the power unit side turntable cover.
3 Remove the drain plug from the bottom of the
hydraulic power unit reservoir.
4 Completely drain the reservoir into a suitable
container.
See capacity specifications listed above.
5 Remove the reservoir mounting fasteners.
Remove the reservoir and clean it using a mild
solvent.
6 Remove the suction strainer and clean it using
a mild solvent.
7 Install the suction strainer.
8 Install the reservoir onto the power unit.
9 Install the reservoir drain plug using a thread
sealant.
10 Fill the reservoir with hydraulic oil until the level
is visible in the sight gauge. Do not overfill.
11 Clean up any oil that may have spilled.
