SIMPLE OPERATION

Start the engine with a push button; use a Bluetooth® key fob or the unique Operator ID function.
Program each joystick button, including power mode, response, and pattern, using Operator ID; the machine will remember what you set each time you go to work.
Automatic hydraulic oil warmup gets you to work faster in cold temperatures and helps prolong the life of components.
Navigate quickly on the high-resolution 254 mm (10 in) touchscreen monitor or with the aid of the jog dial control.
Make moving the excavator much easier with Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.
Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.

EFFICIENCY AND PRODUCTIVITY WITH CAT TECHNOLOGY

Standard Cat Grade with 2D with a retrofit boom indicates depth and slope on the monitor with auditory alerts.
Cat Payload onboard weighing helps you achieve precise load targets to improve your operating efficiency with a retrofit boom. Pick up a load of material – with either a bucket or grapple – and get a real-time weight estimate without even swinging.
Combine Payload with VisionLink® and remotely manage your production targets. The monitor’s USB port lets you download results from one shift all the way up to 30 days of work, so you can manage your progress without needing an internet connection or VisionLink subscription.
The stability monitoring system continuously informs operators of work tool position within the safe working range and warns when approaching the stability limit.
Know the excavator’s exact position relative to GPS and GLONASS systems. The machine automatically compensates for excavator pitch and roll caused by sloping ground conditions.
VisionLink provides actionable data insights for all assets - regardless of fleet size or equipment manufacturer.* Review equipment data from your desktop or mobile device to maximize uptime and optimize assets. Dashboards provide information such as hours, miles, location, idle time, and fuel utilization. Make informed decisions that lower costs, simplify maintenance, and improve safety and security on your jobsite.
VisionLink Productivity gathers and summarizes machine telematics and jobsite data from all your equipment – regardless of the manufacture.* View actionable information such as idle time, fuel burn, location, payload, load counts, total cycles, and more to improve machine efficiency, productivity, and utilization. Access data anywhere via a mobile, tablet, or desktop device - on or off the jobsite.
Remote Flash is a mobile application that allows you to update onboard software without a technician being present, allowing you to initiate software updates when convenient, increasing your overall operating efficiency.

*Data field availability can vary by equipment manufacturer.

MAINTENANCE

Enjoy low maintenance cost due to extended service intervals.
Check hydraulic system oil and easily drain fuel system water and fuel tank water from ground level.
Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
Change all fuel filters at a synchronized 1,000 hours. Oil and fuel filters are grouped and located on the right-hand side of the machine for easy maintenance.
The engine air intake filter with pre-cleaner has double the dust holding capacity of the previous air intake filter.
The hydraulic oil filter provides improved filtration; anti-drain valves keep oil clean when the filter is replaced.
Boost productivity with proactive service reminders. The Integrated vehicle health management system alerts the operator with step-by-step service guidance along with parts needed so you don't experience any unnecessary downtime.
