The primary functions of the hydraulic tank are to
cool and deaerate the hydraulic fluid during
operation. It utilizes internal suction strainers for
the pump supply lines and has an external return
line filter.
How to Remove the
Hydraulic Tank
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.
When removing a hose assembly or fitting, the
fitting and/or hose end must be torqued to
specification during installation. Refer to Section 2,
Hydraulic Hose and Fitting Torque Specifications.
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.

and allow all of the oil from the tank to drain into
a suitable container.
