Check the High Pressure
Hydraulic Filter Condition
Indicator (if equipped)
Maintaining the hydraulic return filter in good
condition is essential to good system performance
and safe machine operation. The filter condition
indicator will show when the hydraulic flow is
bypassing a clogged filter. If the filter is not
frequently checked and replaced, impurities will
remain in the hydraulic system and cause
component damage.
1 Open the engine side turntable cover.
2 Start the engine from the ground controls.
3 Change the engine idle to high rpm (rabbit
symbol).
4 Visually inspect the filter condition indicator.
Result: The filter condition indicator should be
operating with the plunger in the green area. If
the indicator displays the plunger in the red
area, this indicates that the hydraulic filter is
being bypassed and the filter should be
replaced. See D-8, Replace the Hydraulic
Filters.

Test the Oscillate Axle
(if equipped)
Proper axle oscillation is essential to safe machine
operation. If the axle oscillation system is not
operating correctly, the stability of the machine is
compromised and it may tip over.
1 Start the engine from the platform controls.
2 Drive the right steer tire up onto a
6 inch / 15 cm block or curb.
Result: The three remaining tires should stay in
firm contact with the ground.
3 Drive the left steer tire up onto a
6 inch / 15 cm block or curb.
Result: The three remaining tires should stay in
firm contact with the ground.
4 Drive both steer tires up onto a
6 inch / 15 cm block or curb.
Result: The non-steer tires should stay in firm
contact with the ground.
