Note (1)
Net power advertised is the power available at the flywheel when the engine is equipped with fan, air cleaner, CEM exhaust gas aftertreatment, alternator, and cooling fan with engine speed at 2,200 rpm. Advertised power is tested per the specified standard in effect at the time of manufacture.
Note (2)
¹Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels.Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations“ (SEBU6250) for details. * Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).** Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.

Note
The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a (Global Warming Potential = 1430). The system contains 1.0 kg of refrigerant which has a CO2 equivalent of 1.43 metric tonnes.
- Cab Monitor Improvements
- Continuously improved user interface allows for intuitive navigation, minimizing performance interruption with the easy-to-use touchscreen menu.
- Identify apps quickly with a grid list view, abbreviated app names, and categorized menu options.
- A new notification center keeps important information visible to the operator, and displays messages without shrinking the camera view.
- Color coded notifications set critical messages apart from the rest.
- Use the in-monitor QR code to learn about machine and technology features through a full suite of “how-to” videos.
- Enhance visibility to make service work easier and safer with optional inspection lighting.
- Standard integrated vehicle health management system alerts the operator with service guidance and parts needed to enhance uptime.
Build Number: 07D
- The Cat C7.1 engine matches your performance and production needs.
- Up to 5 percent lower fuel consumption compared to M322F.
- Built-in fuel savers like Auto Engine Speed Control and Engine Idle Shutdown eliminate waste.
- Dedicated swing pump allows faster, smoother combined movements.
- Save time with Excavator Tilt Rotator Systems that help you maneuver around obstacles without repositioning the machine
- Travel easily between jobsites with travel speeds up to 30 km/h (19 mph).
- Joystick buttons/sliders can be set up as desired by the operator.
- Enhanced swing lock makes it possible to lock swing and front linkage independently. Don't let the temperature stop you from working. The excavator has a standard high-ambient temperature capability of 52°C (125°F) and cold start capability of -18°C (0°F).

- Everything can be adjusted in the cab from the steering column height to the electrically adjustable mirrors.
- Large split-screen monitor to allow quick view of multiple cameras on the same display.
- Program your power mode and joystick preferences using Operator ID; the excavator remembers your settings each time you go to work.
- Navigate quickly on the standard high-resolution 254 mm (10 inch) touchscreen monitor or with the aid of the jog dial control.
- The auto axle lock presses the pedal for you to reduce your overall number of actions. It also detects when the service brake and axle need to be locked or unlocked.
- The service platform design provides easy, safe, and quick access to the cab; the steps use an anti-skid punch plate to prevent slipping.
- Operator works in clean air thanks to the cabin filtration system that includes precleaner, a recirculation filter, and a cabin pressure monitor.
- Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the pushbutton starting feature.
