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 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 frequently.
Component damage hazard.
The work area and surfaces where this
procedure will be performed must be clean
and free of debris that could get into the
hydraulic system.
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.
Electrocution / burn hazard:
Contact with electrically charged circuits could
result in death or serious injury. Remove all
rings, watches and other jewelry.
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.
1 Disconnect the battery pack from the
machine.
2 Open the power unit module cover.
3 Remove the oil drain plug at bottom Drain
all of the oil into a suitable container.
4 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.
5 Tag and disconnect the hydraulic pump
inlet line and remove the line from the tank.
Cap the fitting on the pump.
6 Remove the hydraulic tank retaining
fasteners and remove the hydraulic tank
from the machine.
7 Open the tank cover and remove the oil
filter.
8 Remove the breather cap from the
hydraulic tank.
9 Clean the inside of the hydraulic tank using
a mild solvent. Allow the tank to dry
completely.
10 Tighten the drain plug.
11 Install a new oil filter onto the tank and
install the tank cover.
12 Install the breather cap onto the hydraulic
tank.
13 Install the hydraulic tank and install and
tighten the hydraulic tank retaining
fasteners.
14 Install the hydraulic pump inlet line into the
tank. Install the fitting onto the pump and
torque.
