1. Be sure the boom is fully retracted and lowered and the
outriggers are retracted and up.
2. Level the crane, engage the parking brake and shut off
the engine.
3. Visually check the oil level on the hydraulic oil level sight
gauge (Figure 5-20). The hydraulic oil should be 3 mm

Check the Air Cleaner Restriction Indicator
The air cleaner is equipped with a filter restriction indicator
(Figure 5-21). The air cleaner element needs cleaning or
replacing if the indicator's colored piston has popped out and
is visible when the engine is running at high idle.
To check the visual indicator the engine must be running.
The filter restriction indicator is visible through the rear cab
window.
Don't remove the element for inspection. Such a check
always does more harm to your engine than the good your
inspection can do. Ridges of dirt on the gasket sealing
surface can drop on the clean filter side when the gasket is
released.
