D-3 Replace Hydraulic Oil Tank Return
Oil Filter Element
Replacing the return oil filter of the hydraulic oil tank is
important for the proper operation and the service life of
the machine. Repeated use of a dirty or blocked filter
could cause damage to the machine components.
Replace the element of the return oil filter more
frequently in very dirty environments.
BURN HAZARD
Allow the hydraulic oil to cool to
room temperature before servicing
the hydraulic system.
NOTICE
Perform this procedure when the hydraulic pump is
turned off.
1. Open the right side door of the chassis and locate
the return filter.
2. Place a suitable container under the return filter of
the hydraulic tank.
HIGH-PRESSURE HAZARD
Slowly remove the hydraulic
components to reduce hydraulic
oil pressure. High hydraulic oil
pressure could penetrate the skin.
Seek medical attention
immediately.
3. Unscrew the return oil filter element.
4. Install and tighten the new return oil filter element.
5. Clean all oil spills during the replacement process.
6. Start the machine and inspect the filter and
hydraulic components to ensure no leakage exists.
D-4 Inspect and Replace Hydraulic Oil
Inspecting and replacing the hydraulic oil is important
for the proper operation and service life of the machine.
The machine may be unable to operate properly if the
hydraulic oil and the filter screen become dirty, and the
hydraulic parts may be damaged after repeated use of
dirty hydraulic oil. Replace the hydraulic oil when the
service environment is very dirty. As required in the
specifications, replace the hydraulic oil once a year.
NOTICE
Before replacing the hydraulic oil, inspect it first. Re-
place the hydraulic oil if required.
Perform this procedure when the platform is retracted
fully.
1. Switch off the power,Open the right door of the
chassis and remove the traveling cut-off protector.
ELECTRICAL SHOCK HAZARD
Be sure to disconnect the battery
from the machine and the charger
from the AC outlet before chang-
ing the hydraulic oil. Contact with
live conductors could result in
death or serious injury.
2. Remove the oil drain plug, and drain the oil into an
appropriate container; the capacity of the hydraulic
oil tank is 15 L.
HIGH-PRESSURE HAZARD
Slowly remove the hydraulic com-
ponents to reduce hydraulic oil
pressure. High hydraulic oil pres-
sure could penetrate the skin.
Seek medical attention
immediately.
3. Disconnect and plug the oil suction pipe.
4. Disconnect and plug the oil return pipe.
5. Remove the bolts from the hydraulic oil tank.
6. Remove the oil tank from the machine.
7. Wash the oil tank inside with clean solvent and al-
low the hydraulic oil tank to dry.
8. Install the hydraulic oil tank on the machine.
9. Install the fastening bolts of the oil tank.
10. Install the oil suction pipe onto the hydraulic oil tank.
11. Install the oil return pipe onto the hydraulic oil tank.
