An air filter restriction indicator for monitoring the
condition of the elements is located in the rubber elbow
at the rear of the air cleaner. If the air filter becomes
restricted, this indicator turns red to warn the operator
that the air cleaner requires service. Push the reset but-
ton located at the end of the indicator after replacing
the element
NOTE: Before replacing the filter element(s),
push the reset button on the indicator. Start the
engine and run at full throttle. If the indicator does
not turn red, do not replace the element(s).
The outer element should be replaced when the restric-
tion indicator turns red. The inner element should be
replaced every third time the outer element is replaced,
unless the outer element is damaged or the inner ele-
ment is visibly dirty. Along with a daily check of the
restriction indicator, check that the air cleaner intake
hose and clamps, and the mounting bracket hardware
are properly secure.
Unlatch the three latches on the air cleaner and remove
the end cap. Clean out any dirt in the end cap.
Primary Element
1. Carefully pull the primary (outer) element out of
the housing. Never remove the secondary (inner)
element unless it is to be replaced.
2. Clean out any dirt in the housing. Leave the sec-
ondary element installed during this step to prevent
debris from entering the engine intake manifold.
3. Use a trouble light inside the new primary element
to inspect for bad spots, pinholes and ruptures.
Replace the primary element if any damage is
found. The primary element must be replaced if it
IMPORTANT: DO NOT OVERFILL! lf the oil level
is too high, oil foaming, excessively high oil tem-
perature and oil leakage at the seals could result.
4. Start and run the machine long enough for the oil
to circulate and warm slightly. Recheck the level
with the dipstick.
CHANGING HYDRAULIC RETURN FIL-
TER ELEMENT
The hydraulic return filter element is a cartridge-type
accessible from a housing on top of the hydraulic reser-
voir. Initial replacement is after the first 100 hours. See
illustration. Remove the top cover of the housing.
Remove the element and discard. Insert the new ele-
ment into the housing and replace the cover.
CHANGING AIR FILTER ELEMENTS
IMPORTANT:
Failure to follow proper filter ser-
vicing instructions could result in catastrophic
engine damage.
The air cleaner assembly consists of an outer (primary)
filter element and an inner (secondary) filter element.
WARNING
Lower the boom to the ground when servicing
the hydraulic system.
