Checklist E Procedures
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 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.
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.
Crushing hazard. Keep
hands clear of the safety arm when lowering
the platform.
1 Raise the platform, use the Safety Arm.
2 Disconnect the battery pack from the
machine.
3 Remove the oil drain plug at bottom.
4 Drain all of the oil into a suitable container.
5 Open the hydraulic tank clear cover.
6 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.
7 Tag and disconnect the hydraulic pump
inlet line and remove the line from the tank.
Cap the fitting on the pump.
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.
12 Install the hydraulic pump inlet line into the
tank. Install the fitting onto the pump and
torque.
13 Install the hydraulic pump return line into
the tank. Install the fitting onto the
hydraulic filter head and torque.
14 Install the hydraulic tank clear cover.
15 Fill the tank with hydraulic oil until the fluid
is full in the hydraulic tank. Do not overfill.
16 Activate the pump to fill the hydraulic
system with oil and bleed the system of air.
