Anleitung Zusammenfassung
Particularly suitable for urban work, these engines have significantly reduced noise levels, one of the lowest fuel consumptions on the market. Engine rotation speed checking via an electric potentiometer. Manual return to idle, control on RH control lever. Engine pre-heating. High performance filtration circuit enables oil change intervals to be extended to every 500 h. Make ...........................................................................................

Load-holding valves on boom and dipper. FILTRATION Hydraulic system components protected by “ULTRA CLEAN” filter which filters out particles larger than 1µ and also traces of condensation water. High performance filtration for longer hydraulic fluid life-time (fluid change interval now 5000 hours). SWING Fixed displacement, axial piston swing motor.

The CX75SR cab has the same level of comfort and convenience as the standard models in the CX range; it is integrated with the upperstructure and therefore does not affect manoeuvrability on 360° swing. It’s still wide enough to provide the operator with maximum comfort and all the advantages of a "standard" machine, including mechanical suspension and a multi-adjustable driver's seat, with a storage compartment to the rear LH of the seat. Mechanical suspension, multi- adjustable driver’s seat (with a storage compartment to the rear LH of the seat). The cab has a large roof window, enabling continuous checking of the bucket position when Attachments To meet user requirements, CASE "short radius" crawler excavators are suitable for every type of work-site. These machines are mainly used on the following types of work: • Construction and maintenance of high speed roads and urban streets. • Construction in residential areas. • Demolition. • Forestry work. • Machine hire companies. To provide best possible profitability in the various sorts of work encountered, machine configuration needs to be able to be changed quickly and easily: the attachment is fully retracted. For operator comfort, the cab is insulated from vibration and noise by four elastofluid mountings. THE ”CASE” ANSWERS • A choice of one-piece or double offset boom for digging vertical walled trenches, regardless of their depth. • A choice of different dipper lengths. • “MULTIFIT” quick coupler. • Supply to the most varied types of implement, using supplementary hydraulic functions (swing, tool orientation, etc.) • Reduced...
