Checklist E Procedure
E-1
Test or Replace the Hydraulic Oil
DINGLI requires that this procedure be
performed every 2000 hours or every two
years, whichever comes first.
Replacement or testing of the hydraulic oil is
essential for good machine performance and
service life. Dirty oil 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.
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.
Note: Perform this procedure with the platform
in the stowed position.
1 Disconnect the battery pack from the
machine.
Electrocution / burn hazard:
Contact with electrically charged circuits could
result in death or serious injury. Remove all
rings, watches and other jewelry.
2 Open the power unit module tray.
3 Remove the oil drain plug at bottom.
4 Drain all of the oil into a suitable container.
5 Tag and disconnect the hydraulic tank
return line from the hydraulic filter head
and remove the line from the tank. Cap the
fitting on the filter head.
6 Tag and disconnect the hydraulic pump
inlet line and remove the line from the tank.
Cap the fitting on the pump.
7 Remove the hydraulic tank retaining
fasteners and remove the hydraulic tank
from the machine.
Bodily injury hazard.
Spraying hydraulic oil can penetrate and burn
skin. Loosen hydraulic connections very slowly
to allow the oil pressure to dissipate gradually.
Do not allow oil to squirt or spray.
8 Clean up any oil that may have spilled.
Properly discard the used oil.
9 Clean the inside of the hydraulic tank using
a mild solvent. Allow the tank to dry
completely.
10 Install a new filter onto the tank.
11 Tighten the drain plug. Torque to
specification.
