Replace the Hydraulic Tank
Return Filter
Replacement of the hydraulic tank return filter
element is essential for good machine performance
and service life. A dirty or clogged filter element
may cause the machine to perform poorly and
continued use may cause component damage.
Extremely dirty conditions may require that the
filter element be replaced more often.
Burn hazard. Beware of hot oil.
Contact with hot oil may cause
severe burns.
The hydraulic filter is mounted on
the function manifold next to the
hydraulic power unit.
1 Clean the area around the hydraulic oil filter.
Remove the filter with an oil filter wrench.
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.
2 Use a permanent ink marker to write the date
and number of hours from the hour meter (if
equipped) on the new filter.
3 Apply a thin layer of fresh oil onto the gasket of
the new oil filter.
4 Install the filter and tighten it securely by hand.
5 Clean up any oil that may have spilled during
the replacement procedure. Properly discard
the used filter.
6 Turn the key switch to ground controls and pull
out the red Emergency Stop button to the on
position at both the ground and platform
controls.
7 Move and hold the function enable toggle switch
in the up direction and activate the platform up
function.
8 Inspect the filter and related components to
be sure that there are no leaks.
