[. . . ] The cab shell is attached to the frame with viscous rubber cab mounts that dampen vibrations and sound levels to enhance operator comfort. Machine Security System An optional Machine Security System (MSS) utilizes a programmable key, deterring theft, vandalism and unauthorized usage. MSS uses electronically coded keys selected by the customer to limit usage by individuals or time parameters. 3 Engine Delivering the most work per liter/gallon of fuel consumed The Cat® C4. 2 engine with ACERTTM Technology optimizes performance and meets U. S. In conjunction with integrated electronics, ACERT Technology reduces emissions during the combustion process by using advanced technology in the air and fuel systems. The Cat C4. 2 engine delivers exceptional power, allowing more hydraulic pressure to drive productivity and reduce your cost per ton of material moved. Automatic Engine Control and Fuel Delivery A two-stage control with one-touch command maximizes fuel efficiency and reduces sound levels. [. . . ] A test connection for the Cat Electronic Technician (Cat ET) service tool is now located in the cab. Air Cleaner A double-layered filter core in the radial seal air filter gives more efficient filtration. A warning is displayed on the monitor when dust accumulates above a preset level. This filter is conveniently located in the compartment behind the cab. An optional pre-cleaner is also available to extend filter life and reduce maintenance costs. Capsule Filter Capsule-type, hydraulic return filter is accessible from outside the tank and prevents contaminants from entering the system when changing the hydraulic oil. Radiator Compartment Horizontal air conditioner condenser swings out for easy cleaning. Removable screens are located in front of the radiator and hydraulic cooler, reducing cleaning time and effort. 8 Technology Products Advanced technologies improve productivity and simplify serviceability AccuGradeTM Systems AccuGradeTM Grade Control Systems are easy to use and deliver a wide range of benefits to customers, including: · Increased productivity · Increased job-site safety · Assistance with labor shortages · Improved employee satisfaction and retention · Increased equipment versatility · Integration into Cat® machines AccuGrade Site Reference System Advanced slope and elevation guidance simplifies excavation, improves accuracy, increases efficiency and lowers production costs. AccuGrade Laser Reference System This system builds on the Site Reference System by using laser receivers to carry benchmark information across a large job site. AccuGrade GPS System GPS satellites allow for precise digging and slope control in real-time for increased accuracy and productivity. E-Ceiling Function The e-ceiling function limits the operation of the boom, stick and bucket ­ except for the swing when the height limit has been set in advance. A height limit is set using the LCD monitor in the cab and must be reset for each bucket. · Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/ windows open) for extended periods or in noisy environment.
