Replace the Hydraulic Tank Return
Filter Element
DINGLI requires that this procedure be
performed every 1000 hours or annually,
whichever comes first.
Replacement of the hydraulic tank 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.
Beware of hot oil. Contact
with hot oil may cause severe burns.
The hydraulic tank return
filter is mounted on the bracket between the
function manifold and the hydraulic power unit.
1 Clean the area around the oil filter.
Remove the filter with an oil filter wrench.
2 Apply a thin layer of oil to the new oil filter
gasket.
3 Install the new filter and tighten it securely
by hand.
4 Use a permanent ink marker to write the
date and number of hours from the hour
meter onto the filter.
5 Turn the key switch to ground control. Pull
out the platform and ground red
Emergency Stop button to the on position.
6 Activate and hold the platform up toggle
switch.
7 Inspect the filter and related components
to be sure that there are no leaks.
8 Clean up any oil that may have spilled.
