Replacing Hydraulic Fluid and Filters
(cont.)

Once the nut is loosened, continue to rotate
the bottom retaining nut CCW until all the
way loose, then pull the bottom portion
(spring and nut) off of the retaining rod to
separate the filter assembly portions from the
filter element.

Separate the used filter element from the top
portion of the holder, by pulling them apart.

With the used filter element removed, wipe
clean any metal fragments from the magnet
using a cloth.

Clean the rubber O-ring on the top half of the
assembly by wiping it with a clean dry cloth.
Inspect the O-ring for damage. If damaged,
remove it and replace with a new O-ring prior
to installing the new filter element-
(see Parts
section for replacement)
.
NOTE: The filter element is partially comprised of
steel, and the top of the filter assembly contains a
powerful magnet for catching any possible metallic
debris within the system. This combination may
require a little finesse when removing and installing
the metal filter.
CAUTION : Make sure hydraulic fluid system has
had at least 30 minutes to cool prior to
maintenance.
CAUTION : It is recommended to wear puncture
proof gloves when cleaning the magnet, as metal
fragments may be sharp and can cut or puncture
skin.
