Replace the Hydraulic Return
Filter
Note: Terex requires that this procedure be
performed every 1000 hours or annually, whichever
comes first.
Replacement of the hydraulic return filter is
essential for good machine performance and
service life. A dirty or clogged filter may cause the
machine to perform poorly and continued use may
cause component damage. Extremely dirty
conditions may require that the filter be replaced
more often.
Bodily injury hazard. Beware of hot
oil. Contact with hot oil may cause
severe burns.
1 Open the road side cabinet cover and locate the
hydraulic return filter next to the power unit.
2 Place a suitable container under the hydraulic
filter.
3 Clean the area around the filter. Remove the
filter with an oil filter wrench.
4 Apply a thin layer of fresh oil to the gasket of
the new oil filter.
5 Install the new filter and tighten it securely by
hand. Clean up any oil that may have spilled.
6 Pull out the red Emergency Stop button (if
equipped) to the on position located on the back
panel of the light tower cabinet.
7 Activate any tower function and inspect the filter
and related components to be sure that there
are no leaks.
8 Use a permanent ink marker to write the date
and number of hours from the hour meter on the
oil filter.
